Question 1Human body systems and disease mechanisms

Which combination includes major modifiable risk factors for cardiovascular disease?

  1. High blood pressure, smoking, high LDL cholesterol, and physical inactivity Correct answer.
  2. Eye color, handedness, and shoe size
  3. Listening to music and reading books
  4. Having a birthday once each year

Explanation

Cardiovascular risk is strongly affected by modifiable factors such as blood pressure, tobacco use, cholesterol patterns, diabetes management, diet, and physical activity. Age and family history also matter but are not modifiable.

Question 2Human body systems and disease mechanisms

Cancer is best described as which process?

  1. Uncontrolled growth and spread of abnormal cells Correct answer.
  2. A normal response to all exercise
  3. A temporary rise in heart rate
  4. A vitamin deficiency only

Explanation

Cancer involves abnormal cells that grow and divide uncontrollably and may invade nearby tissues or spread. Different cancers have different causes, risk factors, screenings, and treatments.

Question 3Human body systems and disease mechanisms

Diabetes is most directly related to problems with which body process?

  1. Regulating blood glucose Correct answer.
  2. Producing hair color
  3. Filtering sound waves
  4. Forming fingerprints

Explanation

Diabetes involves elevated blood glucose due to problems with insulin production, insulin action, or both. Long-term high glucose can damage blood vessels, nerves, kidneys, eyes, and other organs.

Question 4Human body systems and disease mechanisms

Arthritis primarily affects which body structures?

  1. Joints Correct answer.
  2. Teeth enamel only
  3. Hair follicles only
  4. The lens of the eye only

Explanation

Arthritis refers to joint inflammation, pain, stiffness, and related functional limitations. Different types, such as osteoarthritis and rheumatoid arthritis, have different mechanisms.

Question 5Human body systems and disease mechanisms

Which symptom pattern should raise concern for stroke and urgent emergency response?

  1. Sudden face drooping, arm weakness, or speech difficulty Correct answer.
  2. Gradual hunger before lunch
  3. Mild muscle soreness after exercise
  4. Temporary thirst after sweating

Explanation

Sudden facial droop, arm weakness, and speech difficulty are classic warning signs of stroke and require urgent response. Rapid treatment can reduce brain injury and disability.

Question 6Human body systems and disease mechanisms

Which comparison between type 1 and type 2 diabetes is most accurate?

  1. Type 1 involves autoimmune destruction of insulin-producing cells; type 2 often involves insulin resistance. Correct answer.
  2. Type 1 is caused only by eating sugar; type 2 is always contagious.
  3. Type 1 never requires insulin; type 2 always begins in infancy.
  4. Both types are unrelated to blood glucose.

Explanation

Type 1 diabetes usually results from autoimmune destruction of pancreatic beta cells, leading to insulin deficiency. Type 2 diabetes commonly involves insulin resistance and progressive beta-cell dysfunction.

Question 7Human body systems and disease mechanisms

Which description best fits an autoimmune disorder?

  1. The immune system mistakenly attacks the body's own tissues. Correct answer.
  2. The immune system stops recognizing any pathogen.
  3. The body has no immune cells from birth in every case.
  4. The disease is always caused by eating too much protein.

Explanation

In autoimmune disorders, immune responses target self tissues, causing inflammation and damage. Examples include rheumatoid arthritis, type 1 diabetes, and lupus, though each has different mechanisms and effects.

Question 8Human body systems and disease mechanisms

Which comparison between Alzheimer's disease and Parkinson's disease is most accurate?

  1. Alzheimer's disease is commonly associated with progressive memory and cognitive decline; Parkinson's disease commonly involves movement symptoms such as tremor and rigidity. Correct answer.
  2. Both diseases are caused by a single short-term fever.
  3. Parkinson's disease only affects the skin.
  4. Alzheimer's disease is the same as normal forgetfulness.

Explanation

Alzheimer's disease is a common cause of dementia with progressive cognitive decline. Parkinson's disease is a movement disorder, though it can also involve nonmotor symptoms and cognitive changes in some people.

Question 9Human body systems and disease mechanisms

Why do obesity, hypertension, abnormal lipids, and insulin resistance often cluster in chronic disease risk discussions?

  1. They can interact as cardiometabolic risk factors that increase risk for type 2 diabetes and cardiovascular disease. Correct answer.
  2. They are all caused by a single contagious virus.
  3. They are unrelated to diet, activity, sleep, or genetics.
  4. They guarantee immediate symptoms in every person.

Explanation

Cardiometabolic risk factors often cluster and can reinforce risk for diabetes, atherosclerosis, heart disease, and stroke. They are influenced by genetics, environment, behavior, and social conditions, and may be silent for years.

Question 10Infection, immunity and prevention pathways

Which disease is infectious?

  1. Influenza Correct answer.
  2. Osteoarthritis
  3. Type 2 diabetes
  4. Hypertension

Explanation

Influenza is caused by a virus and can spread from person to person. Osteoarthritis, type 2 diabetes, and hypertension are generally discussed as chronic noninfectious conditions, although they have many risk factors.

Question 11Infection, immunity and prevention pathways

Which practice helps reduce transmission of many infectious diseases?

  1. Handwashing with soap and water Correct answer.
  2. Sharing needles
  3. Ignoring vaccination recommendations
  4. Coughing into another person's face

Explanation

Handwashing removes germs and lowers transmission risk for many infections. Vaccination, respiratory etiquette, safe injection practices, and staying home when contagious can also reduce spread.

Question 12Infection, immunity and prevention pathways

Which step in the chain of infection is directly targeted by covering coughs and wearing a mask when sick?

  1. Mode of transmission Correct answer.
  2. Genetic inheritance
  3. Bone remodeling
  4. Nutrient storage

Explanation

Respiratory etiquette and masks can reduce the movement of infectious droplets or aerosols from one person to another. This interrupts the mode of transmission in the chain of infection.

Question 13Infection, immunity and prevention pathways

How can high vaccination coverage protect some people who cannot be vaccinated?

  1. It reduces spread in the community, making exposure less likely. Correct answer.
  2. It makes unvaccinated people produce vaccine records.
  3. It changes all infections into noninfectious diseases.
  4. It guarantees no vaccinated person can ever become infected.

Explanation

When enough people are immune, a pathogen has fewer opportunities to spread, which can indirectly protect vulnerable people. The level needed varies by disease and vaccine effectiveness.

Question 14Infection, immunity and prevention pathways

How does inappropriate antibiotic use contribute to antibiotic resistance?

  1. It kills all bacteria forever.
  2. It creates selection pressure that allows resistant bacteria to survive and spread. Correct answer.
  3. It turns viruses into bacteria.
  4. It makes vaccines unnecessary.

Explanation

Antibiotics can kill susceptible bacteria while resistant strains survive and multiply. Using antibiotics when they are not needed, or not using them as directed, can increase this selection pressure.

Question 15Infection, immunity and prevention pathways

Which factor can increase the risk that an infectious disease emerges or re-emerges?

  1. Global travel, pathogen mutation, animal-to-human transmission, and reduced vaccination coverage Correct answer.
  2. Complete elimination of human contact worldwide
  3. Permanent immunity to all pathogens after one infection
  4. Stopping all disease surveillance

Explanation

Emerging infections can be influenced by travel, ecological change, animal reservoirs, mutation, antimicrobial resistance, and gaps in vaccination or surveillance. Surveillance helps detect outbreaks early rather than increasing safety by being absent.

Question 16Mental health, substance use and cognitive assessment

Which statement best distinguishes mental health from mental illness?

  1. Mental health refers only to the absence of any symptoms.
  2. Mental illness is always caused by weak willpower.
  3. Mental health includes emotional, psychological, and social well-being; mental illness refers to diagnosable conditions that affect functioning. Correct answer.
  4. Mental illness cannot coexist with positive coping skills.

Explanation

Mental health is broader than the absence of illness and includes functioning, coping, relationships, and well-being. A person can have a mental health condition and still use strengths, treatment, and support to function well.

Question 17Mental health, substance use and cognitive assessment

Which finding best illustrates the mind/body connection?

  1. Chronic stress can affect sleep, immune function, blood pressure, and mood. Correct answer.
  2. Exercise has no effect on emotional health.
  3. Mental states are unrelated to physical symptoms.
  4. Only infectious agents can affect the body.

Explanation

The mind/body connection recognizes that psychological states and physical processes influence each other. Chronic stress can alter behavior and physiology, which is why stress management is a health topic rather than only a mood topic.

Question 18Mental health, substance use and cognitive assessment

Why can long-term stress increase disease risk?

  1. It permanently turns off all immune responses.
  2. It can keep stress hormones and unhealthy coping behaviors active over time. Correct answer.
  3. It prevents the body from ever using glucose.
  4. It guarantees that a person will develop a mental disorder.

Explanation

Chronic stress can affect neuroendocrine activity, sleep, inflammation, blood pressure, and coping behaviors such as alcohol use or overeating. It increases risk, but it does not make a specific disease inevitable.

Question 19Mental health, substance use and cognitive assessment

Which public health message best reduces stigma about mental illness?

  1. People with mental illness should be avoided until cured.
  2. Mental illness is treatable, common, and not a personal failure. Correct answer.
  3. Only severe mental illness deserves medical care.
  4. Treatment should be delayed to see whether symptoms disappear.

Explanation

Stigma decreases when mental illness is framed as treatable and as a health issue rather than a character flaw. Reducing stigma encourages earlier help-seeking and social support.

Question 20Mental health, substance use and cognitive assessment

Which pattern best suggests an anxiety disorder rather than ordinary short-term stress?

  1. Feeling tense before a scheduled presentation
  2. Worry that is persistent, excessive, hard to control, and interferes with daily life Correct answer.
  3. Brief sadness after receiving disappointing news
  4. Temporary alertness while driving in heavy traffic

Explanation

Anxiety becomes clinically concerning when it is persistent, disproportionate, difficult to control, and impairing. Normal stress responses are usually tied to a situation and ease when the demand passes.

Question 21Mental health, substance use and cognitive assessment

Why can integrating behavioral health into primary care improve health outcomes?

  1. It separates mental health from chronic disease management.
  2. It lets clinicians address depression, substance use, stress, and adherence during routine medical care. Correct answer.
  3. It removes the need for any specialty referrals.
  4. It limits care to medication-only treatment.

Explanation

Integrated care recognizes that behavior, mental health, and chronic disease management are linked. Screening and brief intervention in primary care can reduce missed needs and improve follow-through.

Question 22Mental health, substance use and cognitive assessment

Which statement best defines addiction?

  1. Compulsive use or behavior that continues despite harmful consequences Correct answer.
  2. Any single use of a legal substance
  3. A habit that is always harmless
  4. A behavior that can be stopped instantly without difficulty

Explanation

Addiction involves impaired control, craving, continued use despite harm, and often changes in reward and stress systems. It is more than simple use or a harmless routine.

Question 23Mental health, substance use and cognitive assessment

What does tolerance mean in substance use?

  1. Needing less of a substance to get the same effect
  2. Needing more of a substance to get the same effect Correct answer.
  3. Being unable to metabolize any drug
  4. Having no withdrawal symptoms

Explanation

Tolerance occurs when repeated exposure reduces response, so more of the substance may be needed to produce the same effect. Tolerance can contribute to escalating use and overdose risk.

Question 24Mental health, substance use and cognitive assessment

Which substance in tobacco products is primarily responsible for addiction?

  1. Nicotine Correct answer.
  2. Calcium
  3. Vitamin C
  4. Fiber

Explanation

Nicotine is the addictive drug in tobacco products and many e-cigarettes. Smoke and aerosol can contain many other harmful chemicals, but nicotine drives dependence.

Question 25Mental health, substance use and cognitive assessment

Why do many addictive substances strongly affect dopamine pathways?

  1. Dopamine is unrelated to reward or learning.
  2. Dopamine signaling helps reinforce behaviors by linking them to reward and motivation. Correct answer.
  3. Dopamine prevents all withdrawal symptoms.
  4. Dopamine exists only in the liver.

Explanation

Dopamine is involved in reward, motivation, and reinforcement learning. Addictive substances can powerfully stimulate these pathways, making the brain more likely to repeat substance-seeking behavior.

Question 26Mental health, substance use and cognitive assessment

A person who stops heavy alcohol use develops tremors, sweating, and anxiety. Which concept best explains these symptoms?

  1. Withdrawal Correct answer.
  2. Protective immunity
  3. Placebo effect only
  4. Nutrient density

Explanation

Withdrawal occurs when the body has adapted to a substance and symptoms appear after reducing or stopping it. Alcohol withdrawal can be medically serious and may require supervised care.

Question 27Mental health, substance use and cognitive assessment

Which feature is most important in identifying a substance use disorder?

  1. Use causes significant impairment, risky behavior, or continued use despite problems. Correct answer.
  2. The substance was legal for adults.
  3. The person used the substance one time.
  4. The person has never experienced withdrawal.

Explanation

Substance use disorder is defined by a pattern that produces impairment or distress, not simply by whether a substance is legal. Problems such as impaired control, risky use, tolerance, withdrawal, and continued use despite harm are key signs.

Question 28Mental health, substance use and cognitive assessment

Why is naloxone used in opioid overdose response?

  1. It reverses opioid effects at receptors and can restore breathing temporarily. Correct answer.
  2. It cures opioid use disorder in one dose.
  3. It increases alcohol metabolism.
  4. It prevents nicotine withdrawal.

Explanation

Naloxone is an opioid antagonist that can rapidly reverse life-threatening respiratory depression from opioid overdose. It is an emergency intervention, not a complete treatment plan for opioid use disorder.

Question 29Mental health, substance use and cognitive assessment

Which tobacco-cessation approach is usually strongest for a person who is ready to quit?

  1. Relying only on willpower and avoiding all support
  2. Combining behavioral counseling with approved cessation medication when appropriate Correct answer.
  3. Switching to more cigarettes with lower tar labels
  4. Waiting until symptoms of lung disease appear

Explanation

Cessation is often more successful when counseling, coping strategies, and evidence-based medications are combined. Waiting for disease or choosing misleading lower-tar products does not address nicotine dependence.

Question 30Mental health, substance use and cognitive assessment

Which health effect is associated with long-term heavy alcohol use?

  1. Reduced risk of liver disease in all users
  2. Increased risk of liver disease, some cancers, hypertension, and injuries Correct answer.
  3. Permanent immunity to infection
  4. Guaranteed improvement in sleep quality

Explanation

Long-term heavy alcohol use is associated with multiple harms, including liver disease, increased cancer risk, high blood pressure, injuries, and mental health problems. Alcohol can disrupt sleep even when it initially causes drowsiness.

Question 31Mental health, substance use and cognitive assessment

Which behavior can be considered a non-substance addiction when it becomes persistent, compulsive, and harmful?

  1. Gambling Correct answer.
  2. Handwashing before meals
  3. Eating vegetables
  4. Wearing a seat belt

Explanation

Gambling can become addictive when it involves loss of control, craving, financial harm, and continued behavior despite consequences. The key is the compulsive harmful pattern, not simply repeating an activity.

Question 32Mental health, substance use and cognitive assessment

A patient has opioid use disorder and major depression. Which care approach is most appropriate?

  1. Treat only the substance use and ignore depression.
  2. Treat only depression and assume substance use will disappear.
  3. Use integrated care that addresses both conditions and their interaction. Correct answer.
  4. Delay all care until both conditions resolve spontaneously.

Explanation

Co-occurring mental health and substance use disorders often influence each other. Integrated assessment and treatment can improve adherence, safety, relapse prevention, and overall functioning.

Question 33Mental health, substance use and cognitive assessment

Why is physical dependence not the same as addiction?

  1. Dependence can occur with medically supervised use, while addiction involves compulsive use despite harm. Correct answer.
  2. Dependence always means illegal drug use.
  3. Addiction never involves withdrawal.
  4. Dependence has no relationship to the body adapting to a substance.

Explanation

Physical dependence means the body has adapted and may experience withdrawal if the substance stops. Addiction includes behavioral loss of control and continued use despite harm, and it may or may not include physical dependence.

Question 34Mental health, substance use and cognitive assessment

Which counselor response best reflects motivational interviewing for a person ambivalent about quitting alcohol?

  1. You are wrong, and I will tell you what to do.
  2. It sounds like drinking helps you relax, but you are also worried about your blood pressure. Tell me more about that. Correct answer.
  3. There is no need to discuss your reasons for change.
  4. You should feel ashamed before you can improve.

Explanation

Motivational interviewing uses empathy, reflective listening, and exploration of ambivalence to strengthen the person's own reasons for change. Confrontation and shame often increase defensiveness rather than readiness.

Question 35Mental health, substance use and cognitive assessment

Which relapse-prevention plan is most complete?

  1. Avoid thinking about triggers so they disappear.
  2. Identify high-risk triggers, practice coping skills, build support, and plan what to do after a lapse. Correct answer.
  3. Assume one lapse means treatment has failed permanently.
  4. Focus only on punishment for future use.

Explanation

Relapse prevention prepares for predictable risks and builds coping responses before cravings occur. A lapse can be used as information for strengthening the plan rather than proof of failure.

Question 36Development, context and assessment across childhood

Where does human fertilization most commonly occur?

  1. Ovary
  2. Fallopian tube Correct answer.
  3. Uterine lining
  4. Cervix

Explanation

Fertilization usually occurs in the fallopian tube after ovulation. The fertilized egg then travels toward the uterus, where implantation can occur.

Question 37Development, context and assessment across childhood

Which contraceptive method also helps reduce the transmission of many sexually transmitted infections when used correctly?

  1. Condom Correct answer.
  2. Intrauterine device
  3. Oral contraceptive pill
  4. Fertility awareness only

Explanation

Condoms are barrier methods that can reduce exposure to semen, vaginal fluids, and some skin-to-skin contact. Hormonal and intrauterine methods can prevent pregnancy but do not provide the same STI barrier protection.

Question 38Development, context and assessment across childhood

Which feature is essential to a healthy sexual relationship?

  1. One partner making all decisions
  2. Consent that is voluntary, informed, and ongoing Correct answer.
  3. Avoiding communication to prevent conflict
  4. Using jealousy as proof of commitment

Explanation

Healthy relationships require respect, communication, and consent that can be freely given or withdrawn. Coercion, control, and intimidation undermine consent and relationship safety.

Question 39Development, context and assessment across childhood

Which change is generally considered a normal part of healthy aging?

  1. A gradual decrease in maximal aerobic capacity Correct answer.
  2. Sudden severe confusion in a day
  3. Complete loss of all long-term memory
  4. Inevitable inability to learn new skills

Explanation

Some gradual physical changes, such as lower maximal aerobic capacity, are common with aging. Sudden confusion or major memory loss should be evaluated because they are not simply normal aging.

Question 40Development, context and assessment across childhood

Which statement about grief is most accurate?

  1. Everyone moves through the same stages in the same order.
  2. Grief responses vary and may include emotional, physical, cognitive, and social changes. Correct answer.
  3. Healthy grieving always ends within a fixed number of weeks.
  4. Talking about the loss always makes grief worse.

Explanation

Grief is highly individual and can affect feelings, thoughts, sleep, appetite, energy, and relationships. Stage models can be useful descriptions, but they should not be treated as a required sequence.

Question 41Development, context and assessment across childhood

Why is alcohol avoidance recommended during pregnancy?

  1. Alcohol cannot cross the placenta.
  2. Only the last month of pregnancy is sensitive to alcohol.
  3. Alcohol exposure can disrupt fetal development and cause lifelong effects. Correct answer.
  4. The fetus metabolizes alcohol faster than the adult.

Explanation

Alcohol can cross the placenta and affect the developing brain and body. Because no risk-free amount is established for pregnancy, avoidance is the safest recommendation.

Question 42Development, context and assessment across childhood

A teenager is exploring values, future roles, and personal beliefs. Which developmental task is most directly involved?

  1. Object permanence
  2. Identity formation Correct answer.
  3. Conservation of mass
  4. Integrity versus despair

Explanation

Adolescence is often associated with identity formation, including exploration of roles, values, beliefs, and goals. Object permanence and conservation are earlier cognitive milestones, while integrity versus despair is typically linked to later adulthood.

Question 43Development, context and assessment across childhood

Menopause is best defined as which event?

  1. The beginning of ovulation
  2. The permanent end of menstrual periods after ovarian hormone changes Correct answer.
  3. A disease that always requires emergency treatment
  4. The first menstrual period

Explanation

Menopause is the permanent end of menstruation related to declining ovarian function and is commonly confirmed after 12 months without a menstrual period. It is a normal life transition, though symptoms and health concerns may need care.

Question 44Development, context and assessment across childhood

Which communication pattern is most consistent with a healthy intimate relationship?

  1. Using threats to win disagreements
  2. Listening, stating needs clearly, and respecting boundaries Correct answer.
  3. Keeping finances secret to maintain control
  4. Monitoring a partner's phone to prevent independence

Explanation

Healthy relationships depend on respectful communication, trust, and boundaries. Threats, secrecy for control, and monitoring are warning signs of unhealthy or abusive dynamics.

Question 45Development, context and assessment across childhood

In a typical menstrual cycle, what is ovulation?

  1. The release of an egg from an ovary Correct answer.
  2. The implantation of an embryo in the uterus
  3. The shedding of the uterine lining
  4. The fertilization of the egg

Explanation

Ovulation is the release of an egg from an ovary. Menstruation is shedding of the uterine lining, fertilization is union of egg and sperm, and implantation occurs later in the uterus.

Question 46Development, context and assessment across childhood

Which strategy best reduces caregiver strain when caring for an older adult with chronic illness?

  1. Refusing all outside help to preserve privacy
  2. Using respite care, support groups, and shared care planning Correct answer.
  3. Ignoring the caregiver's own sleep and medical needs
  4. Waiting until a crisis before seeking resources

Explanation

Caregiver strain is reduced by practical support, respite, education, and shared decision-making. Supporting the caregiver protects both the caregiver's health and the quality of care for the older adult.

Question 47Development, context and assessment across childhood

Why do contraceptive failure rates often differ between perfect use and typical use?

  1. Perfect use includes real-world missed doses and inconsistent condom use.
  2. Typical use reflects how people actually use the method, including errors or inconsistent use. Correct answer.
  3. Typical use assumes all users are infertile.
  4. Perfect use is always less effective than typical use.

Explanation

Perfect use estimates effectiveness when a method is used exactly as directed every time. Typical use includes human behavior, such as missed pills, delayed injections, or incorrect condom use.

Question 48Development, context and assessment across childhood

Why is social support considered protective across development?

  1. It eliminates every stressful event.
  2. It can buffer stress, encourage healthy behavior, and improve coping. Correct answer.
  3. It replaces the need for medical care.
  4. It only matters during childhood.

Explanation

Supportive relationships can reduce the impact of stress and make healthy behavior easier to maintain. Social support matters across the life span, including adolescence, adulthood, and older age.

Question 49Nutrients, digestion and metabolic reasoning

Which activity primarily improves cardiorespiratory endurance?

  1. Brisk walking for 30 minutes Correct answer.
  2. Holding a single static stretch
  3. Reading a nutrition label
  4. Weighing food portions

Explanation

Brisk walking challenges the heart, lungs, and large muscles over time, making it an aerobic activity. Stretching improves flexibility, while label reading and weighing food relate to nutrition behavior.

Question 50Nutrients, digestion and metabolic reasoning

Flexibility refers to which ability?

  1. The ability of a joint to move through its range of motion Correct answer.
  2. The maximum force a muscle can produce once
  3. The number of calories in a gram of protein
  4. The amount of oxygen in the blood after infection

Explanation

Flexibility is range of motion at a joint or group of joints. It differs from muscular strength, nutrition values, and oxygen saturation.
