Question 1Health Promotion, Disease Prevention, and Anticipatory Guidance

A 4-month-old infant is seen for a routine well-child visit. Which feeding guidance is most appropriate to give the parents at this age?

  1. Introduce pureed fruits and cereals to improve sleep
  2. Offer water between feeds to prevent dehydration
  3. Continue breast milk or iron-fortified formula as the sole source of nutrition Correct answer.
  4. Begin whole cow's milk to increase calcium intake

Explanation

Exclusive milk feeding (breast milk or iron-fortified formula) is recommended until about 6 months, when complementary foods are introduced alongside continued milk feeding. Whole cow's milk is not recommended before 12 months because of low iron content and renal solute load. Water supplementation is generally unnecessary in this age group.

Question 2Health Promotion, Disease Prevention, and Anticipatory Guidance

A 2-year-old child has a hemoglobin of 9.8 g/dL with microcytic indices and a low ferritin. The family reports the child drinks about 1 liter of cow's milk daily and eats little meat. Which single recommendation most directly addresses the likely cause?

  1. Increase juice intake to improve iron absorption
  2. Limit cow's milk to about 16-24 oz per day and offer iron-rich foods Correct answer.
  3. Add a daily multivitamin containing vitamin C only
  4. Switch to low-fat milk to reduce total calorie intake

Explanation

Excessive cow's milk intake is a classic cause of iron deficiency in toddlers because it displaces iron-rich foods and impairs iron absorption. Limiting milk to roughly 16-24 oz daily while emphasizing iron-rich foods addresses the mechanism. Vitamin C aids absorption but does not correct the underlying dietary excess of milk.

Question 3Health Promotion, Disease Prevention, and Anticipatory Guidance

According to standard immunization schedules, at which age is the first dose of measles-mumps-rubella vaccine typically recommended in healthy children?

  1. At 12-15 months Correct answer.
  2. At 2 months
  3. At 4-6 years
  4. At birth

Explanation

The first MMR dose is recommended at 12-15 months, when maternal antibody interference has waned and the child can mount a durable response. A second dose is given at 4-6 years or at least 28 days after the first. Earlier administration may be indicated for travel or outbreaks but is not the routine schedule.

Question 4Health Promotion, Disease Prevention, and Anticipatory Guidance

A 65-year-old man with no symptoms asks about colorectal cancer screening. He has average risk and no family history. Which statement best reflects current screening guidance?

  1. Screening is only indicated if rectal bleeding develops
  2. Screening ends at age 60 regardless of prior results
  3. Screening should begin at age 45-50 and continue to about age 75 Correct answer.
  4. Screening should begin at age 30 for all average-risk adults

Explanation

Average-risk colorectal cancer screening is recommended to begin around age 45-50 and continue through about age 75, using colonoscopy or stool-based testing. Symptom-based testing misses the purpose of screening, which is detection before symptoms appear. Earlier or later start ages apply to specific risk groups, not average-risk adults.

Question 5Health Promotion, Disease Prevention, and Anticipatory Guidance

A 50-year-old woman with obesity and prediabetes asks what lifestyle change would most reduce her risk of progressing to type 2 diabetes. Which recommendation is best supported?

  1. Losing 5-7% of body weight with 150 minutes of moderate activity weekly Correct answer.
  2. Starting a very-low-calorie diet indefinitely
  3. Avoiding all carbohydrate-containing foods
  4. Taking a daily multivitamin with chromium

Explanation

Large trials show that modest weight loss of about 5-7% combined with 150 minutes per week of moderate-intensity activity substantially reduces progression from prediabetes to diabetes. Extreme or indefinite restriction is not sustainable and is not the recommended approach. Supplements and complete carbohydrate avoidance lack this evidence base.

Question 6Health Promotion, Disease Prevention, and Anticipatory Guidance

A 16-year-old presents for a sports physical. Which counseling topic is most important to address as part of adolescent anticipatory guidance?

  1. Initiation of statin therapy
  2. Routine use of helmets and seat belts Correct answer.
  3. Menopause planning
  4. Scheduling of adult cancer screening

Explanation

Unintentional injury is the leading cause of death in adolescents, so counseling on helmet use, seat belts, and safe driving is a core preventive topic. Cancer screening, statins, and menopause planning are not relevant to a healthy adolescent. Anticipatory guidance should match the developmental stage.

Question 7Health Promotion, Disease Prevention, and Anticipatory Guidance

A pregnant patient at 10 weeks asks about folic acid. Which recommendation is standard?

  1. Start 400 mcg daily only after 20 weeks
  2. 400-800 mcg daily starting before conception and through early pregnancy Correct answer.
  3. 4 mg daily for all pregnant patients
  4. No supplementation if the diet includes leafy greens

Explanation

Folic acid 400-800 mcg daily is recommended before conception and through early pregnancy to reduce neural tube defects. The 4 mg dose is reserved for patients with a prior affected pregnancy or specific risk factors. Dietary intake alone is often insufficient to reach the target.

Question 8Health Promotion, Disease Prevention, and Anticipatory Guidance

A 70-year-old woman reports two falls in the past year. Which intervention has the strongest evidence for reducing future falls?

  1. Prescribing a benzodiazepine for sleep
  2. Encouraging use of a cane without assessment
  3. Bed rest to prevent further injury
  4. A structured balance and strength exercise program Correct answer.

Explanation

Exercise programs targeting balance and lower-extremity strength reduce fall risk in older adults. Sedatives increase fall risk, and bed rest promotes deconditioning. Assistive devices should follow individualized assessment rather than being recommended reflexively.

Question 9Health Promotion, Disease Prevention, and Anticipatory Guidance

Which counseling approach best supports smoking cessation in a patient who is not yet ready to quit?

  1. Brief motivational counseling and an offer to help when ready Correct answer.
  2. Prescribing nicotine replacement without discussion
  3. Refusing to see the patient until they quit
  4. Stating that quitting is easy if they try harder

Explanation

For patients not ready to quit, motivational approaches and maintaining open offers of support are more effective than confrontation. Prescribing pharmacotherapy without agreement undermines engagement. Dismissive or judgmental language damages the therapeutic relationship.

Question 10Health Promotion, Disease Prevention, and Anticipatory Guidance

A 3-year-old is brought for a well-child visit. Which developmental screening approach is most consistent with current recommendations?

  1. Screening only if the child is not speaking in sentences
  2. Standardized developmental screening at 9, 18, and 30 months Correct answer.
  3. Informal observation only unless a parent raises a concern
  4. Screening only at school entry

Explanation

Standardized developmental screening is recommended at 9, 18, and 30 months, with autism-specific screening at 18 and 24 months. Relying on informal observation or waiting for parent concern misses children with delays. Screening should not be deferred to school entry.

Question 11Health Promotion, Disease Prevention, and Anticipatory Guidance

A 55-year-old woman is due for cervical cancer screening and has had normal results for many years. Which option reflects typical current guidance for average-risk screening?

  1. Cytology every 3 years or co-testing every 5 years, with exit around age 65 if adequately screened Correct answer.
  2. Annual cytology for life
  3. Screening only after symptoms develop
  4. Screening every 10 years with co-testing

Explanation

Average-risk cervical cancer screening typically uses cytology every 3 years or HPV co-testing every 5 years, with cessation around age 65 for those with adequate prior normal screening. Annual cytology for life is not recommended, and symptom-based testing is not screening. A 10-year interval exceeds recommended intervals.

Question 12Health Promotion, Disease Prevention, and Anticipatory Guidance

A parent asks how to reduce the risk of sudden infant death syndrome. Which set of practices is recommended?

  1. Place the infant supine on a firm surface with no soft bedding Correct answer.
  2. Use a soft pillow to keep the head elevated
  3. Place the infant prone to prevent choking
  4. Share the bed with the infant to promote bonding

Explanation

Supine sleep on a firm, flat surface without soft bedding reduces SIDS risk. Prone sleeping and soft objects increase risk. Bed sharing is not recommended because of suffocation and entrapment hazards, although room sharing is encouraged.

Question 13Health Promotion, Disease Prevention, and Anticipatory Guidance

A 45-year-old man has a blood pressure of 138/88 mmHg on two occasions and no other cardiovascular risk factors. Which initial management is most appropriate?

  1. No follow-up needed because the value is normal
  2. Starting two antihypertensive drugs immediately
  3. Lifestyle counseling with recheck in several weeks Correct answer.
  4. Diagnosing hypertensive emergency

Explanation

Values in the elevated or stage 1 range without high risk generally warrant lifestyle counseling and repeat measurement before pharmacotherapy. Immediate dual therapy is reserved for higher-risk or markedly elevated cases. This is not a hypertensive emergency, and the value is not normal.

Question 14Health Promotion, Disease Prevention, and Anticipatory Guidance

Which vaccine is contraindicated in a patient with severe immunodeficiency?

  1. Recombinant hepatitis B vaccine
  2. Live attenuated measles-mumps-rubella vaccine Correct answer.
  3. Tetanus-diphtheria toxoid
  4. Inactivated influenza vaccine

Explanation

Live attenuated vaccines such as MMR carry a risk of disseminated infection in severely immunocompromised patients and are contraindicated. Inactivated and toxoid vaccines are generally safe because they cannot replicate. Recombinant vaccines are likewise non-infectious.

Question 15Health Promotion, Disease Prevention, and Anticipatory Guidance

A 30-year-old woman asks about screening for sexually transmitted infections. She is asymptomatic and reports a new partner. Which approach is most appropriate?

  1. Offer screening for chlamydia and gonorrhea and discuss HIV testing Correct answer.
  2. Test only if symptoms develop
  3. Defer all testing until she plans pregnancy
  4. Tell her testing is unnecessary without symptoms

Explanation

Asymptomatic sexually transmitted infections are common, so screening is based on risk rather than symptoms. Offering chlamydia and gonorrhea testing plus HIV screening is appropriate for a patient with a new partner. Waiting for symptoms or pregnancy misses the opportunity for prevention and treatment.

Question 16Health Promotion, Disease Prevention, and Anticipatory Guidance

A 6-year-old is overweight. Which counseling message best aligns with obesity prevention guidance for children?

  1. Focus only on the child's weight without involving parents
  2. Start pharmacotherapy as first-line treatment
  3. Place the child on a very restrictive calorie diet
  4. Encourage family meals, limit sugar-sweetened beverages, and increase active play Correct answer.

Explanation

Pediatric obesity prevention emphasizes family-level changes such as shared meals, reduced sugar-sweetened beverages, and at least 60 minutes of daily activity. Very restrictive diets can impair growth and are not first-line. Parental involvement is essential because the family shapes the child's environment.

Question 17Health Promotion, Disease Prevention, and Anticipatory Guidance

A 60-year-old woman has a 10-year cardiovascular risk of 12% and no diabetes. Which preventive strategy is most appropriate?

  1. Start high-dose statin without discussion
  2. Discuss a statin for primary prevention alongside lifestyle changes Correct answer.
  3. Avoid statins because she has no prior heart attack
  4. Order a coronary calcium scan before any discussion

Explanation

At a 10-year risk around 10-20%, shared decision-making about a moderate-intensity statin plus lifestyle change is appropriate. Statins are not limited to secondary prevention. High-dose therapy without discussion or mandatory imaging before any conversation is not the standard first step.

Question 18Health Promotion, Disease Prevention, and Anticipatory Guidance

A newborn is born to a mother who is hepatitis B surface antigen positive. Which action is indicated at birth?

  1. Give hepatitis B vaccine and hepatitis B immune globulin within 12 hours Correct answer.
  2. Give immune globulin only if the infant becomes jaundiced
  3. Give hepatitis B vaccine alone at 2 months
  4. Delay all immunizations until 6 months

Explanation

Infants born to HBsAg-positive mothers should receive both hepatitis B vaccine and hepatitis B immune globulin within 12 hours of birth to prevent perinatal transmission. Delaying to 2 months or later substantially increases the risk of chronic infection. Jaundice is not the trigger for prophylaxis.

Question 19Health Promotion, Disease Prevention, and Anticipatory Guidance

A 75-year-old man with diabetes asks about pneumococcal vaccination. Which statement is most accurate?

  1. Vaccination is needed only after a pneumonia episode
  2. Pneumococcal vaccination is recommended for adults with diabetes according to age- and product-specific schedules Correct answer.
  3. Only children require pneumococcal vaccination
  4. Pneumococcal vaccination is contraindicated in diabetes

Explanation

Adults with diabetes are at increased risk for invasive pneumococcal disease, and vaccination is recommended following current age- and product-specific schedules. Diabetes is an indication, not a contraindication. Vaccination is preventive and should not wait for an episode of pneumonia.

Question 20Health Promotion, Disease Prevention, and Anticipatory Guidance

A 40-year-old woman reports binge drinking on weekends. Which screening tool is specifically designed to identify unhealthy alcohol use in primary care?

  1. Apgar score
  2. Mini-Cog
  3. AUDIT-C questionnaire Correct answer.
  4. PHQ-9

Explanation

The AUDIT-C is a brief validated tool for identifying hazardous drinking and is widely used in primary care. The PHQ-9 screens for depression, the Mini-Cog for cognition, and the Apgar for newborn status. Matching the tool to the condition is essential for valid screening.

Question 21Health Promotion, Disease Prevention, and Anticipatory Guidance

A 68-year-old woman has osteopenia on DXA and a history of a hip fracture in her mother. Which preventive recommendation is most appropriate?

  1. Avoid exercise because of fracture risk
  2. Recommend bed rest to protect the bones
  3. Ensure adequate calcium and vitamin D and encourage weight-bearing exercise Correct answer.
  4. Start high-dose vitamin D without any other measures

Explanation

Bone health is supported by adequate calcium and vitamin D intake and regular weight-bearing and muscle-strengthening exercise. Bed rest and exercise avoidance accelerate bone loss and increase fall risk. High-dose vitamin D alone is not a substitute for a comprehensive approach.

Question 22Health Promotion, Disease Prevention, and Anticipatory Guidance

A 25-year-old woman with no chronic illness asks about routine immunizations. She has no record of varicella vaccination or infection. What is the appropriate approach?

  1. Give varicella vaccine only after exposure occurs
  2. Offer varicella vaccination unless contraindicated, such as in pregnancy or immunodeficiency Correct answer.
  3. Assume immunity and give no vaccine
  4. Give varicella vaccine during pregnancy

Explanation

Adults without evidence of varicella immunity should be vaccinated unless contraindicated. Live varicella vaccine is contraindicated during pregnancy and in significant immunodeficiency. Post-exposure vaccination is not the primary preventive strategy for routine care.

Question 23Health Promotion, Disease Prevention, and Anticipatory Guidance

A 35-year-old woman has a body mass index of 32 and asks about weight management. Which counseling approach is most consistent with behavior-change principles?

  1. Focus only on the number on the scale
  2. Set specific, achievable goals with self-monitoring and regular follow-up Correct answer.
  3. Recommend a single rapid weight-loss program without follow-up
  4. Advise skipping meals to reduce intake

Explanation

Effective weight counseling uses specific, achievable goals, self-monitoring, and ongoing follow-up to support sustainable behavior change. One-time rapid programs without follow-up rarely produce durable results. Skipping meals and focusing only on weight undermine healthy habits.

Question 24Health Promotion, Disease Prevention, and Anticipatory Guidance

A 12-month-old is due for health supervision. Which preventive topic should be emphasized at this visit?

  1. Mammography
  2. Lead screening and injury prevention in the home Correct answer.
  3. Routine cholesterol screening
  4. Colorectal cancer screening

Explanation

At 12 months, health supervision emphasizes lead screening where indicated and home injury prevention as the child becomes mobile. Cholesterol, colorectal cancer, and mammography screening apply to older age groups. Anticipatory guidance should match the child's developmental stage.

Question 25Health Promotion, Disease Prevention, and Anticipatory Guidance

A patient with chronic obstructive pulmonary disease asks how to reduce exacerbations. Which combination is best supported?

  1. Routine antibiotics every month
  2. Avoiding all physical activity
  3. Smoking cessation, recommended vaccinations, and inhaler adherence Correct answer.
  4. Stopping inhaled therapy when symptoms improve

Explanation

Smoking cessation, appropriate vaccination, and adherence to prescribed inhaled therapy reduce COPD exacerbations. Avoiding activity leads to deconditioning, and routine monthly antibiotics promote resistance. Inhaled therapy should be continued as prescribed rather than stopped when symptoms improve.

Question 26Health Promotion, Disease Prevention, and Anticipatory Guidance

During a routine health supervision visit, a clinician wants to apply the US Preventive Services Task Force (USPSTF) framework to a preventive service. Which statement best describes how the USPSTF assigns a grade to a preventive service?

  1. The grade is assigned by each insurer based on local coverage determinations for the service
  2. The grade reflects the certainty and magnitude of net benefit from the evidence for the service in the general population Correct answer.
  3. The grade reflects the cost-effectiveness ratio of the service relative to other preventive services
  4. The grade reflects the number of years a service has been available in clinical practice

Explanation

The USPSTF assigns letter grades based on the certainty of the evidence and the magnitude of net benefit (benefits minus harms) for a preventive service in the general population. A grade of A or B indicates high or moderate certainty of substantial or moderate net benefit and generally triggers coverage without cost sharing under the Affordable Care Act. Grades of C, D, and I reflect smaller net benefit, net harm, or insufficient evidence.

Question 27Health Promotion, Disease Prevention, and Anticipatory Guidance

A 52-year-old man with no symptoms asks about colorectal cancer screening. Which statement about screening options is most accurate?

  1. Colonoscopy every 10 years and annual fecal immunochemical testing are both acceptable screening strategies Correct answer.
  2. Screening should begin at age 60 for all average-risk adults
  3. A single negative stool test is sufficient to stop screening permanently
  4. Only colonoscopy is an acceptable screening method for average-risk adults

Explanation

For average-risk adults, multiple screening strategies are acceptable, including colonoscopy every 10 years and annual fecal immunochemical testing (FIT). The choice depends on patient preference, availability, and adherence. Screening generally starts at age 45 and continues to about age 75, with individualized decisions thereafter.

Question 28Health Promotion, Disease Prevention, and Anticipatory Guidance

A 24-year-old woman with no chronic conditions is due for routine immunizations. She has no documentation of prior HPV vaccination. Which recommendation is most consistent with current guidance?

  1. HPV vaccination should be deferred until she has an abnormal Pap test
  2. HPV vaccination is not indicated because she is older than 18
  3. Offer HPV vaccination now, since catch-up vaccination is recommended through age 26 Correct answer.
  4. HPV vaccination is recommended only for patients with multiple partners

Explanation

HPV vaccination is routinely recommended at ages 11 to 12 and catch-up vaccination is recommended through age 26 for those not adequately vaccinated. Shared clinical decision-making applies for ages 27 through 45. Vaccination is not contingent on sexual history or Pap results.

Question 29Health Promotion, Disease Prevention, and Anticipatory Guidance

A 58-year-old woman with prediabetes (A1c 6.1%) asks what she can do to reduce her risk of progressing to type 2 diabetes. Which counseling is best supported by evidence?

  1. Restricting carbohydrate intake to less than 20 grams daily
  2. Starting basal insulin now to normalize glucose
  3. A structured behavioral program targeting 7% weight loss and 150 minutes of moderate activity weekly Correct answer.
  4. Annual A1c testing only, with no lifestyle changes unless diabetes develops

Explanation

The Diabetes Prevention Program showed that a structured lifestyle intervention aiming for about 7% weight loss and at least 150 minutes of moderate-intensity activity per week reduced progression to diabetes by roughly 58%. This is the cornerstone of counseling for prediabetes. Metformin may be considered in selected higher-risk patients but is not first-line for most.

Question 30Health Promotion, Disease Prevention, and Anticipatory Guidance

A 32-year-old woman is planning pregnancy and has never had varicella infection or vaccination. Which counseling is most appropriate?

  1. Receive varicella immune globulin before conception
  2. Avoid vaccination entirely because she has no history of chickenpox
  3. Receive varicella vaccine now and delay conception for at least one month Correct answer.
  4. Receive varicella vaccine during the first trimester of pregnancy

Explanation

Varicella vaccine is a live vaccine and is contraindicated during pregnancy, but it can be given before conception with a recommendation to avoid pregnancy for at least one month afterward. Preconception counseling is the ideal time to update live-vaccine status. Immunity should be documented because varicella in pregnancy carries maternal and fetal risks.

Question 31Health Promotion, Disease Prevention, and Anticipatory Guidance

A 66-year-old man with hypertension and a 10-year atherosclerotic cardiovascular disease risk of 8% is considering statin therapy. Which statement best reflects current guidance?

  1. Statin therapy should be started only after a coronary calcium score of zero
  2. Moderate-intensity statin therapy is reasonable after a clinician-patient risk discussion Correct answer.
  3. High-intensity statin therapy is required regardless of his risk estimate
  4. Statin therapy is not indicated because his risk is below 20%

Explanation

For adults aged 40 to 75 with at least one risk factor and a 10-year risk between 7.5% and 20%, moderate-intensity statin therapy is reasonable after a risk discussion. Decision aids and risk enhancers can refine the decision. High-intensity therapy is generally reserved for higher-risk patients or those with clinical ASCVD.

Question 32Health Promotion, Disease Prevention, and Anticipatory Guidance

A 45-year-old woman with a body mass index of 34 kg/m² and no other risk factors asks about screening for type 2 diabetes. Which recommendation is most consistent with current guidance?

  1. Screen now with fasting glucose or A1c and repeat at least every 3 years if normal Correct answer.
  2. Screen with a random glucose once and never repeat if normal
  3. Defer screening until she reaches age 50
  4. Screen only if she develops symptoms of hyperglycemia

Explanation

Screening for prediabetes and type 2 diabetes is recommended for adults aged 35 to 70 with overweight or obesity, and earlier for those with additional risk factors. If results are normal, repeat screening at least every 3 years is reasonable. Symptom-based testing alone would miss asymptomatic dysglycemia.

Question 33Health Promotion, Disease Prevention, and Anticipatory Guidance

A 70-year-old woman with osteoporosis and a prior vertebral fracture asks about preventing future fractures. Which combination is best supported?

  1. Pharmacologic therapy plus adequate calcium and vitamin D intake, weight-bearing exercise, and fall prevention Correct answer.
  2. Estrogen therapy as first-line treatment at her age
  3. Calcium and vitamin D alone without pharmacologic therapy
  4. Bed rest to reduce the risk of falls

Explanation

For a patient with osteoporosis and a fragility fracture, pharmacologic therapy is indicated, combined with adequate calcium and vitamin D, weight-bearing and muscle-strengthening exercise, and fall-prevention measures. This multifactorial approach addresses bone density and fall risk simultaneously. Estrogen is not first-line at age 70 because of its risk profile.

Question 34Health Promotion, Disease Prevention, and Anticipatory Guidance

A 38-year-old woman reports drinking four to five drinks on most weekends and denies daily drinking. Which screening approach best identifies unhealthy alcohol use in this setting?

  1. A validated brief instrument such as AUDIT-C, followed by brief intervention if positive Correct answer.
  2. Waiting for her to report alcohol-related consequences spontaneously
  3. Ordering liver enzymes as the sole screening method
  4. Asking only whether she has ever been told she has a drinking problem

Explanation

Validated brief instruments such as AUDIT-C or the single-question screen are recommended for detecting unhealthy alcohol use in primary care. Positive screens should be followed by brief behavioral counseling, which is effective in reducing risky drinking. Liver enzymes lack sensitivity and specificity for this purpose.

Question 35Health Promotion, Disease Prevention, and Anticipatory Guidance

A 62-year-old woman has a family history of breast cancer in a first-degree relative diagnosed at age 48. She has no symptoms. Which approach to risk assessment is most appropriate?

  1. Use a validated family history tool to estimate risk and discuss genetic counseling and earlier or supplemental screening if indicated Correct answer.
  2. Order a breast MRI as a first-line screening test for all women with any family history
  3. Recommend prophylactic bilateral mastectomy immediately
  4. Recommend average-risk mammography only and do not address family history

Explanation

A validated family history tool should be used to identify women at increased risk who may benefit from genetic counseling, earlier screening, or supplemental imaging such as MRI. Risk assessment guides whether enhanced screening or genetic evaluation is warranted. Prophylactic surgery is reserved for very high-risk patients after appropriate counseling.

Question 36Health Promotion, Disease Prevention, and Anticipatory Guidance

A 50-year-old man recently immigrated and has no documentation of prior hepatitis B testing. He feels well. Which screening approach is most appropriate?

  1. Defer screening because he is asymptomatic
  2. Test only liver enzymes and treat if elevated
  3. Screen with hepatitis B surface antigen alone and no further testing
  4. Screen with hepatitis B surface antigen, surface antibody, and core antibody to determine infection and immunity status Correct answer.

Explanation

For adults at increased risk, including people born in regions with high hepatitis B prevalence, screening with hepatitis B surface antigen, surface antibody, and core antibody distinguishes chronic infection, prior infection, and immunity. This informs vaccination and linkage to care. Liver enzymes alone cannot establish infection status.

Question 37Growth, Development, and Developmental-Behavioral Assessment

According to Piaget's theory, a 9-month-old who searches for a toy hidden under a cloth demonstrates that object permanence is beginning to develop. In which stage does this typically first occur?

  1. Sensorimotor stage Correct answer.
  2. Preoperational stage
  3. Concrete operational stage
  4. Formal operational stage

Explanation

Object permanence emerges during the sensorimotor stage, roughly between 8 and 12 months, as infants begin to represent objects that are no longer visible. The preoperational, concrete operational, and formal operational stages all occur later and involve different cognitive achievements.

Question 38Growth, Development, and Developmental-Behavioral Assessment

A toddler points at a dog and says "doggie," and the parent responds "Yes, that's a doggie!" This exchange best illustrates which language-learning process?

  1. Reinforcement of babbling
  2. Recasting and expansion Correct answer.
  3. Overregularization
  4. Fast mapping

Explanation

Expansion occurs when an adult repeats the child's utterance in a fuller or corrected form, and recasting rephrases it, both supporting vocabulary and syntax growth. Here the parent confirms and models the word, which fits this category rather than error patterns or single-trial word learning.

Question 39Growth, Development, and Developmental-Behavioral Assessment

A 4-year-old can use scissors to cut a straight line but cannot yet tie shoelaces or button small buttons. Which developmental domain do these skills primarily reflect?

  1. Fine motor skills Correct answer.
  2. Social-emotional skills
  3. Gross motor skills
  4. Receptive language

Explanation

Fine motor skills involve precise hand and finger movements such as cutting, drawing, and manipulating fasteners. Gross motor skills involve large muscle movement, while language and social-emotional domains are unrelated to these manual tasks.

Question 40Growth, Development, and Developmental-Behavioral Assessment

At what age do most typically developing infants first achieve independent sitting without support?

  1. About 15 to 18 months
  2. About 2 to 3 months
  3. About 11 to 12 months
  4. About 6 to 8 months Correct answer.

Explanation

Independent sitting without support typically emerges between 6 and 8 months of age in most infants. Earlier sitting usually requires support, and later milestones such as walking occur after the first birthday.

Question 41Growth, Development, and Developmental-Behavioral Assessment

A clinician uses the Denver II to screen a 2-year-old. What is the primary purpose of this type of screening instrument?

  1. To determine eligibility for special education services
  2. To identify children who may need more comprehensive developmental evaluation Correct answer.
  3. To measure intelligence quotient precisely
  4. To diagnose autism spectrum disorder definitively

Explanation

Developmental screening tools such as the Denver II are designed to flag children whose development may be delayed so they can be referred for fuller assessment. They are not diagnostic instruments and do not establish IQ or service eligibility on their own.

Question 42Growth, Development, and Developmental-Behavioral Assessment

A 10-month-old who was born at 28 weeks gestation is being assessed for developmental delay. Which adjustment should the clinician apply when interpreting milestones?

  1. Use the corrected age only after 3 years
  2. Correct for prematurity by subtracting the weeks born early from chronological age Correct answer.
  3. Add the weeks of prematurity to chronological age
  4. Use chronological age without correction

Explanation

Corrected age is calculated by subtracting the number of weeks the infant was born before term from chronological age, which is standard practice for interpreting milestones in preterm infants. This correction is typically applied until about 2 years of age.

Question 43Growth, Development, and Developmental-Behavioral Assessment

A 15-month-old has a vocabulary of about 5 words and does not point to indicate interest. Which statement best describes the clinical significance?

  1. Delayed expressive vocabulary combined with reduced joint attention warrants further evaluation Correct answer.
  2. This is entirely within normal limits and no follow-up is needed
  3. The child should be diagnosed with autism spectrum disorder immediately
  4. Vocabulary size at 15 months has no predictive value

Explanation

By 15 months most children use several words and show joint attention behaviors such as pointing. A small vocabulary plus absent pointing raises concern and warrants developmental evaluation rather than immediate diagnosis.

Question 44Growth, Development, and Developmental-Behavioral Assessment

Which of the following best describes the concept of a developmental quotient (DQ) as used in assessment?

  1. The ratio of developmental age to chronological age multiplied by 100 Correct answer.
  2. The number of milestones achieved per year of life
  3. The difference between verbal and performance scores
  4. The child's percentile rank on a normed intelligence test

Explanation

Developmental quotient is traditionally computed as developmental age divided by chronological age, multiplied by 100. It provides an index of developmental progress relative to age rather than a percentile or a discrepancy score.

Question 45Growth, Development, and Developmental-Behavioral Assessment

A 3-year-old uses two-word phrases such as "more juice" and "daddy go." A clinician notes this is below expectations. What is the typical expectation for phrase speech at this age?

  1. Single words only
  2. Two- to three-word phrases and simple sentences Correct answer.
  3. Narrative storytelling with past tense
  4. Complex sentences with subordinate clauses

Explanation

By age 3, most children combine words into short phrases and simple sentences and are increasingly intelligible to unfamiliar listeners. Single-word communication at this age would be delayed, while complex syntax and narratives develop later.

Question 46Growth, Development, and Developmental-Behavioral Assessment

Which assessment approach gathers information from parents and teachers about a child's behavior across home and school settings?

  1. Direct standardized cognitive testing
  2. Multi-informant rating scales Correct answer.
  3. Vision and hearing screening
  4. Neuroimaging

Explanation

Multi-informant rating scales collect observations from caregivers and teachers to capture behavior across settings. This cross-setting information is essential because behavior can vary by environment.

Question 47Growth, Development, and Developmental-Behavioral Assessment

A 6-year-old is described as egocentric and unable to take another person's perspective. According to Piaget, this is most characteristic of which stage?

  1. Concrete operational
  2. Preoperational Correct answer.
  3. Formal operational
  4. Sensorimotor

Explanation

Egocentrism and difficulty with perspective-taking are hallmarks of the preoperational stage, roughly ages 2 to 7. Concrete operational children begin to decenter, and formal operational adolescents can reason abstractly about others' viewpoints.

Question 48Growth, Development, and Developmental-Behavioral Assessment

Which of the following is a key feature of the Brazelton Neonatal Behavioral Assessment Scale (NBAS)?

  1. It assesses newborn behavioral organization and responsiveness Correct answer.
  2. It evaluates adolescent identity development
  3. It diagnoses language disorders
  4. It measures school readiness

Explanation

The NBAS assesses the newborn's behavioral organization, including reflexes, state regulation, and responsiveness to stimulation. It is designed for the neonatal period and does not address school-age or adolescent domains.

Question 49Growth, Development, and Developmental-Behavioral Assessment

A clinician wants to assess a child's adaptive behavior. Which domain is most relevant?

  1. Daily living skills such as dressing and feeding Correct answer.
  2. Abstract reasoning
  3. Phonological awareness
  4. Visual acuity

Explanation

Adaptive behavior refers to the practical skills needed for everyday functioning, including self-care, communication, and social skills. Abstract reasoning, phonological awareness, and visual acuity belong to cognitive, language, and sensory domains respectively.

Question 50Growth, Development, and Developmental-Behavioral Assessment

A 4-year-old is unable to hop on one foot and has difficulty pedaling a tricycle. Which developmental area should be evaluated first?

  1. Phonemic awareness
  2. Social reciprocity
  3. Receptive vocabulary
  4. Gross motor coordination Correct answer.

Explanation

Hopping and pedaling are gross motor skills that typically emerge in the preschool years. Difficulty with these tasks points to gross motor coordination as the primary area for evaluation.
