Question 1Maternal and Infant Anatomy and Physiology

A woman is unsure when she conceived, so her pregnancy is dated by ultrasound. According to standard obstetric convention, gestational age is counted from which point?

  1. The estimated day of conception
  2. The day of ovulation
  3. The first day of her last menstrual period Correct answer.
  4. The day of implantation

Explanation

Gestational age is conventionally calculated from the first day of the last menstrual period, not from fertilization. This makes gestational age roughly two weeks longer than the true post-conception age. Accurate dating matters because screening and growth thresholds are all defined against this convention.

Question 2Maternal and Infant Anatomy and Physiology

Which structure carries oxygenated blood from the placenta toward the fetal inferior vena cava?

  1. The foramen ovale
  2. The ductus venosus Correct answer.
  3. The umbilical arteries
  4. The ductus arteriosus

Explanation

The ductus venosus shunts oxygenated umbilical blood past the fetal liver directly into the inferior vena cava. Umbilical arteries carry deoxygenated blood away from the fetus toward the placenta. The foramen ovale and ductus arteriosus are intracardiac and great-vessel shunts downstream of this step.

Question 3Maternal and Infant Anatomy and Physiology

Which change in maternal physiology most directly increases oxygen delivery to the fetus during pregnancy?

  1. A decrease in plasma volume that concentrates haemoglobin
  2. A rise in maternal respiratory rate to roughly double resting values
  3. An increase in circulating 2,3-diphosphoglycerate that shifts the maternal oxygen curve rightward Correct answer.
  4. A fall in functional residual capacity with unchanged minute ventilation

Explanation

Pregnancy raises 2,3-DPG, shifting the maternal oxyhaemoglobin dissociation curve rightward so oxygen is unloaded more readily at the placenta. The fetus has a leftward-shifted curve with higher haemoglobin affinity, favouring uptake. This rightward maternal shift complements the rise in cardiac output and alveolar ventilation.

Question 4Maternal and Infant Anatomy and Physiology

Which layer of the uterus undergoes the greatest cyclical thickening and is shed during menstruation?

  1. The myometrium
  2. The endometrium Correct answer.
  3. The serosa
  4. The perimetrium

Explanation

The endometrium is the inner mucosal lining that proliferates under oestrogen and is shed at menstruation. The myometrium is the thick smooth muscle layer responsible for contractility in labour. The perimetrium and serosa refer to the outer covering, which is not shed.

Question 5Maternal and Infant Anatomy and Physiology

Fertilisation normally occurs in which part of the female reproductive tract?

  1. The cervix
  2. The isthmus of the fallopian tube
  3. The ampulla of the fallopian tube Correct answer.
  4. The fundus of the uterus

Explanation

The ampulla, the widened mid-portion of the fallopian tube, is the usual site of fertilisation. The isthmus is the narrower portion nearer the uterus where the embryo is later transported. Implantation occurs in the endometrium, not in the tube.

Question 6Maternal and Infant Anatomy and Physiology

A midwife notes that a newborn's head has moulded during labour. Which feature of the fetal skull best explains this capacity?

  1. Fusion of the cranial sutures before birth
  2. Complete ossification of the parietal bones at term
  3. Presence of membranous sutures and fontanelles between skull bones Correct answer.
  4. A rigid cartilaginous cranial vault

Explanation

The fetal cranial vault bones are separated by membranous sutures and fontanelles, allowing them to overlap and mould during passage through the birth canal. This mobility reduces the diameter of the presenting head. The sutures ossify only after birth.

Question 7Maternal and Infant Anatomy and Physiology

Which fetal presentation is described when the sacrum is the presenting part?

  1. Occiput posterior
  2. Transverse
  3. Breech Correct answer.
  4. Cephalic

Explanation

In a breech presentation the fetal pelvis or sacrum lies over the maternal pelvic inlet. Cephalic presentation means the head presents, and occiput posterior describes a head position rather than a different presenting part. A transverse lie presents a shoulder.

Question 8Maternal and Infant Anatomy and Physiology

Which hormone is primarily responsible for maintaining the corpus luteum and thus progesterone production in early pregnancy?

  1. Human chorionic gonadotrophin Correct answer.
  2. Prolactin
  3. Follicle-stimulating hormone
  4. Oxytocin

Explanation

Human chorionic gonadotrophin from the syncytiotrophoblast sustains the corpus luteum, which secretes progesterone until the placenta takes over. Falling LH would otherwise cause luteal regression. Progesterone from the corpus luteum is essential for maintaining the early pregnancy.

Question 9Maternal and Infant Anatomy and Physiology

The placenta produces which hormone in amounts that rise progressively across pregnancy and can contribute to insulin resistance?

  1. Calcitonin
  2. Human placental lactogen Correct answer.
  3. Thyroid-stimulating hormone
  4. Antidiuretic hormone

Explanation

Human placental lactogen rises through pregnancy and opposes insulin action, contributing to gestational glucose intolerance. It also supports fetal nutrient supply by altering maternal metabolism. The other listed hormones are not placental products of this kind.

Question 10Maternal and Infant Anatomy and Physiology

Which description best characterises the decidua basalis?

  1. The portion of endometrium lining the rest of the uterine cavity
  2. The portion of endometrium at the implantation site, forming the maternal part of the placenta Correct answer.
  3. The portion of endometrium covering the fetal surface of the membranes
  4. The layer of trophoblast that invades the myometrium

Explanation

The decidua basalis lies between the implanting conceptus and the myometrium and becomes the maternal component of the placenta. The decidua capsularis covers the conceptus on its cavity side, and the decidua parietalis lines the remaining cavity. Trophoblast is fetal tissue, not decidua.

Question 11Maternal and Infant Anatomy and Physiology

A woman at 34 weeks has a fundal height measured with a tape. Which landmark should the tape be placed on inferiorly for a standard symphysis-fundal height measurement?

  1. The sacral promontory
  2. The umbilicus
  3. The anterior superior iliac spine
  4. The upper border of the symphysis pubis Correct answer.

Explanation

Symphysis-fundal height is measured from the upper border of the symphysis pubis to the highest palpable point of the uterine fundus. The umbilicus is a surface landmark but not the fixed inferior reference. Consistency of landmarks allows serial measurements to be compared.

Question 12Maternal and Infant Anatomy and Physiology

Which maternal cardiovascular change is typical of normal pregnancy?

  1. A rise in systemic vascular resistance
  2. A fall in stroke volume across gestation
  3. An increase in cardiac output of roughly 30 to 50 percent Correct answer.
  4. A fall in resting heart rate of about 15 beats per minute

Explanation

Cardiac output rises substantially in pregnancy, mainly through increased stroke volume and later heart rate, alongside plasma volume expansion. Systemic vascular resistance falls because of vasodilatation and the low-resistance placental circuit. Resting heart rate increases rather than falls.

Question 13Maternal and Infant Anatomy and Physiology

Which change in renal physiology explains the glycosuria sometimes seen in healthy pregnancy?

  1. An increase in glomerular filtration rate with reduced tubular reabsorption of filtered glucose Correct answer.
  2. A fall in renal plasma flow
  3. Increased secretion of glucose by the tubules
  4. A rise in the renal threshold for glucose

Explanation

Glomerular filtration rate rises by around 50 percent in pregnancy while tubular reabsorptive capacity for glucose does not rise proportionately, so filtered glucose may escape into urine. This produces physiological glycosuria in some healthy women. The renal threshold for glucose is effectively lowered.

Question 14Maternal and Infant Anatomy and Physiology

Which blood vessel in the umbilical cord normally carries the most highly oxygenated blood?

  1. The descending fetal aorta
  2. The two umbilical arteries
  3. The single umbilical vein Correct answer.
  4. The ductus arteriosus

Explanation

The single umbilical vein returns oxygenated blood from the placenta to the fetus. The two umbilical arteries carry deoxygenated blood from the fetus back to the placenta. Downstream fetal vessels become progressively less oxygenated as blood is distributed to tissues.

Question 15Maternal and Infant Anatomy and Physiology

Which structure normally closes functionally within hours after birth to become the ligamentum teres of the liver?

  1. The foramen ovale
  2. The umbilical artery
  3. The ductus arteriosus
  4. The umbilical vein Correct answer.

Explanation

After birth the intra-abdominal portion of the umbilical vein obliterates and becomes the ligamentum teres. The ductus arteriosus becomes the ligamentum arteriosum, and the foramen ovale closes into the fossa ovalis. The umbilical arteries become the medial umbilical ligaments.

Question 16Maternal and Infant Anatomy and Physiology

Which statement about the fontanelles of the newborn skull is correct?

  1. Both fontanelles are fused at birth in a normal term infant
  2. The anterior fontanelle is triangular and closes by about six weeks
  3. The posterior fontanelle is diamond-shaped and closes last
  4. The anterior fontanelle is diamond-shaped and normally closes between about 9 and 18 months Correct answer.

Explanation

The anterior fontanelle is the larger, diamond-shaped gap between the frontal and parietal bones and normally closes in the second year of life. The posterior fontanelle is smaller and triangular and closes earlier, usually within a few months. Fontanelles are open at birth to allow moulding and brain growth.

Question 17Maternal and Infant Anatomy and Physiology

During a vaginal examination in labour the fetal head is felt with the sagittal suture in the transverse diameter and the occiput directed toward the maternal left. Which position is this?

  1. Direct occipito-anterior
  2. Left occipito-lateral
  3. Right occipito-transverse
  4. Left occipito-transverse Correct answer.

Explanation

When the occiput points to the maternal left and the sagittal suture lies in the transverse diameter, the position is left occipito-transverse. Occipito-anterior and occipito-posterior refer to the occiput lying toward the front or back of the maternal pelvis. The side named is the maternal side toward which the occiput points.

Question 18Maternal and Infant Anatomy and Physiology

Which pelvic plane represents the narrowest anteroposterior diameter that the fetal head must negotiate?

  1. The pelvic outlet
  2. The mid-cavity at the level of the ischial spines Correct answer.
  3. The pelvic inlet
  4. The plane of the sacral promontory

Explanation

The mid-cavity, at the level of the ischial spines, is the narrowest part of the pelvic canal in the anteroposterior dimension, and the head engages and rotates around this level. The inlet and outlet are wider in that dimension. Understanding this helps interpret arrest of descent.

Question 19Maternal and Infant Anatomy and Physiology

Which statement correctly describes the fetal haemoglobin dissociation curve compared with the maternal curve?

  1. It is shifted right, giving lower oxygen affinity
  2. It is identical to the maternal curve at term
  3. It is shifted left only after birth
  4. It is shifted left, giving higher oxygen affinity at any given partial pressure Correct answer.

Explanation

Fetal haemoglobin binds 2,3-DPG less avidly, shifting its dissociation curve leftward so it has a higher oxygen affinity than adult haemoglobin. This allows the fetus to extract oxygen from maternal blood across the placenta. The difference is present throughout fetal life before birth.

Question 20Maternal and Infant Anatomy and Physiology

A newborn's ductus arteriosus fails to close after birth. Which physiological change at birth normally triggers its closure?

  1. A rise in pulmonary blood flow and arterial oxygen tension Correct answer.
  2. A fall in systemic vascular resistance
  3. A fall in arterial oxygen tension
  4. Closure of the foramen ovale

Explanation

With the first breaths, pulmonary vascular resistance falls and pulmonary blood flow rises, while arterial oxygen tension increases; these changes promote constriction and closure of the ductus arteriosus. A persistent left-to-right shunt results if it stays open. Low oxygen and high pulmonary resistance favour patency in fetal life.

Question 21Maternal and Infant Anatomy and Physiology

Which component of breast tissue is responsible for milk production during lactation?

  1. The suspensory ligaments
  2. The alveolar secretory epithelium Correct answer.
  3. The lactiferous sinus
  4. The myoepithelial cells

Explanation

Milk is synthesised and secreted by the alveolar epithelial cells of the mammary gland lobules. Myoepithelial cells contract to eject milk in response to oxytocin but do not produce it. The lactiferous sinuses store milk and the suspensory ligaments provide structural support.

Question 22Maternal and Infant Anatomy and Physiology

Which reflex is responsible for milk ejection from the alveoli during breastfeeding?

  1. The progesterone withdrawal reflex
  2. The prolactin surge reflex
  3. The oxytocin-mediated let-down reflex Correct answer.
  4. The sympathetic suck reflex

Explanation

Suckling stimulates oxytocin release, which causes myoepithelial cells to contract and eject milk, known as the let-down reflex. Prolactin drives milk synthesis rather than ejection. Progesterone withdrawal initiates lactogenesis but is not the ejection mechanism.

Question 23Maternal and Infant Anatomy and Physiology

Which mechanism best explains why the fetal heart rate can be heard with a Pinard stethoscope over the lower abdomen in a cephalic presentation?

  1. The umbilical cord conducts fetal heart sounds to the maternal pelvis
  2. Sound travels through the maternal abdominal wall best from the fetal heart directly beneath the umbilicus
  3. Maternal aortic pulsation is heard because it is louder than the fetal heart
  4. Sound is transmitted through the fetal chest and conducted most clearly over the fetal back near the presenting part Correct answer.

Explanation

Fetal heart sounds are best heard through the fetal back, so in a cephalic presentation the auscultation point lies in the lower abdomen on the side of the fetal back. The heart itself is not directly against the abdominal wall. Distinguishing fetal heart rate from maternal pulse is essential in auscultation.

Question 24Maternal and Infant Anatomy and Physiology

Which maternal adaptation helps prevent supine hypotension in late pregnancy during normal daily activity?

  1. A rise in uterine artery pressure when the uterus compresses the aorta
  2. Increased venous return through the inferior vena cava in the supine position
  3. Compensatory vasodilatation of the lower limbs
  4. Activation of the sympathetic baroreflex with peripheral vasoconstriction and tachycardia Correct answer.

Explanation

When the gravid uterus compresses the inferior vena cava, venous return falls and cardiac output drops; the baroreflex responds with vasoconstriction and tachycardia to maintain blood pressure. This compensation is limited, which is why supine hypotension can still occur. Left lateral tilt relieves the compression.

Question 25Maternal and Infant Anatomy and Physiology

Which statement about the formation of the amniotic fluid in early pregnancy is most accurate?

  1. It is produced by the fetal lungs throughout pregnancy
  2. It is produced predominantly by fetal urine from the first weeks
  3. It is derived initially from maternal plasma across the amnion and later supplemented by fetal urine Correct answer.
  4. It is formed by secretion from the decidua basalis only

Explanation

Early amniotic fluid is largely a transudate of maternal plasma across the amniotic membrane; as the fetal kidneys mature, fetal urine becomes the major contributor. Fetal swallowing regulates volume by removing fluid. Lung liquid contributes only a small amount.

Question 26Maternal and Infant Anatomy and Physiology

A midwife is asked to explain how the fetal circulation adapts after birth. Which change in the umbilical vessels normally occurs once the cord is clamped and the newborn breathes?

  1. The umbilical arteries reverse flow direction and carry oxygenated blood to the liver.
  2. The umbilical arteries constrict and become the medial umbilical ligaments. Correct answer.
  3. The umbilical vein dilates to carry systemic venous return to the inferior vena cava.
  4. The umbilical vein becomes the ligamentum venosum within the falciform ligament.

Explanation

After birth, the umbilical arteries contract and fibrose to form the medial umbilical ligaments, while the intra-abdominal portion of the umbilical vein becomes the ligamentum teres. The ductus venosus, a separate vessel, becomes the ligamentum venosum. These obliterations reflect the loss of placental circulation once pulmonary gas exchange begins.

Question 27Maternal and Infant Anatomy and Physiology

A woman at 32 weeks' gestation reports a sudden gush of clear fluid and is found to have a fundal height smaller than expected. Which structure is the most likely source of the fluid in this situation?

  1. The choroid plexus, from increased fetal cerebrospinal fluid production
  2. The maternal bladder, from stress incontinence of pregnancy
  3. The decidua capsularis, from normal secretory activity
  4. The amniotic sac, from spontaneous rupture of membranes Correct answer.

Explanation

A sudden gush of clear fluid in pregnancy most commonly represents spontaneous rupture of the fetal membranes, releasing amniotic fluid. After rupture, the volume of liquor decreases, which can make fundal height measure smaller than expected for gestation. Amniotic fluid in later pregnancy is mainly fetal urine, with a smaller contribution from lung secretions.

Question 28Maternal and Infant Anatomy and Physiology

During a routine antenatal visit, a midwife palpates the abdomen to determine fetal lie. Which statement best describes the relationship between fetal lie and the long axis of the uterus?

  1. Lie describes whether the fetal long axis is longitudinal, transverse, or oblique to the uterus. Correct answer.
  2. Lie describes the part of the fetus that enters the pelvic brim first.
  3. Lie describes the degree of flexion of the fetal head at the pelvic inlet.
  4. Lie describes the position of the fetal back relative to the maternal abdomen.

Explanation

Fetal lie refers to the orientation of the fetal long axis relative to the long axis of the uterus, and is described as longitudinal, transverse, or oblique. It is distinct from presentation, which identifies the presenting part, and from position, which describes the relationship of the presenting part to the maternal pelvis. Attitude concerns the degree of flexion of the fetal body.

Question 29Maternal and Infant Anatomy and Physiology

A newborn is noted to have a small anterior fontanelle that closes early, and the midwife considers the timing of normal closure. Which statement about normal fontanelle closure is most accurate?

  1. The posterior fontanelle normally closes by about 6 to 8 weeks after birth.
  2. The anterior fontanelle normally closes by about 6 weeks after birth.
  3. Both fontanelles normally remain open until 18 months of age.
  4. The anterior fontanelle normally closes between about 9 and 18 months of age. Correct answer.

Explanation

The anterior fontanelle is diamond-shaped and normally closes between roughly 9 and 18 months of age, while the posterior fontanelle is triangular and usually closes within the first 6 to 8 weeks. Early closure of the anterior fontanelle warrants assessment for craniosynostosis. Knowing normal timing helps the midwife distinguish variation from pathology.

Question 30Maternal and Infant Anatomy and Physiology

A labouring woman has a pelvic assessment that identifies a prominent sacral promontory and a narrowed sacrosciatic notch. Which pelvic shape is most consistent with these findings, and what is its clinical significance?

  1. Gynecoid pelvis, which is the most favourable shape for vaginal delivery.
  2. Anthropoid pelvis, which has a long anteroposterior diameter and favours occipitoposterior positions.
  3. Android pelvis, which is associated with a narrowed subpubic arch and a higher risk of obstructed labour. Correct answer.
  4. Platypelloid pelvis, which has a wide transverse diameter and a flattened anteroposterior diameter.

Explanation

The android pelvis is heart-shaped with a prominent sacral promontory, narrow sacrosciatic notches, and a narrow subpubic arch. These features reduce the available diameters and increase the likelihood of difficult descent and obstructed labour. The gynecoid pelvis, by contrast, is rounded and most favourable for birth.

Question 31Normal Breastfeeding and Lactation Management

A breastfeeding parent reports that her 3-week-old feeds about 8 times in 24 hours and has 6 wet diapers daily. Which statement best describes this pattern?

  1. Feeding frequency and diaper output both fall within expected ranges for a 3-week-old Correct answer.
  2. Wet diapers are adequate but the feeding frequency suggests inadequate intake
  3. Feeding frequency is adequate but the wet diaper count is too low for this age
  4. Both feeding frequency and diaper output indicate a need for immediate supplementation

Explanation

Most breastfed newborns feed roughly 8 to 12 times per 24 hours, and after the first week a minimum of about 6 wet diapers daily is a reassuring sign of adequate intake. Combining an 8-feed pattern with 6 wet diapers therefore fits normal expectations. Clinical assessment should still include weight trajectory and feeding quality, but neither value alone signals a problem.

Question 32Normal Breastfeeding and Lactation Management

Which hormone is primarily responsible for milk ejection (the let-down reflex) during breastfeeding?

  1. Human placental lactogen
  2. Prolactin
  3. Progesterone
  4. Oxytocin Correct answer.

Explanation

Oxytocin released from the posterior pituitary causes myoepithelial cells around the alveoli to contract, ejecting milk into the ducts. Prolactin supports milk synthesis rather than ejection. Progesterone and placental lactogen are pregnancy-related hormones that decline around birth.

Question 33Normal Breastfeeding and Lactation Management

A parent with a 5-day-old infant has firm, engorged breasts and a slightly elevated temperature of 37.8°C with no focal redness or systemic symptoms. What is the most appropriate first-line management?

  1. Apply firm binding to the breasts to reduce swelling
  2. Immediate referral for antibiotic therapy
  3. Frequent effective milk removal through feeding or expression Correct answer.
  4. Stop breastfeeding for 24 hours to allow the breasts to rest

Explanation

Physiologic engorgement is managed primarily by frequent, effective milk removal, which relieves pressure and maintains supply. Mild temperature elevation without focal signs can accompany engorgement and usually resolves with milk removal. Binding and abrupt cessation worsen congestion and are not recommended.

Question 34Normal Breastfeeding and Lactation Management

Which statement about colostrum is accurate?

  1. It is produced only after the milk comes in around day 3 to 5
  2. It is high in volume and low in protein compared with mature milk
  3. It is rich in immunoglobulins, especially secretory IgA, and acts as a laxative Correct answer.
  4. It contains mostly fat and is designed to promote rapid weight gain

Explanation

Colostrum is produced from late pregnancy and is concentrated in immunoglobulins, particularly secretory IgA, and has a laxative effect that helps clear meconium. It is low in volume but high in protein and protective factors relative to mature milk. It is present before mature milk production begins.

Question 35Normal Breastfeeding and Lactation Management

A mother describes a deep stabbing breast pain that occurs between feeds and radiates to the back, with no fever. Which cause should be considered?

  1. Simple nipple trauma from a shallow latch
  2. Normal let-down sensation
  3. Physiologic engorgement
  4. Candida infection of the nipple and ductal tissue Correct answer.

Explanation

Burning or stabbing pain that persists between feeds and may radiate to the back is characteristic of candidal infection involving the nipple and ductal tissue. Let-down sensation is typically a brief tingling at the start of the feed. Nipple trauma pain is usually localized and related to latch.

Question 36Normal Breastfeeding and Lactation Management

Which of the following best describes the recommended position for a mother with a preterm infant who is not yet able to feed at the breast?

  1. Begin expressing within the first 1 to 2 hours after birth and express at least 8 times daily Correct answer.
  2. Provide formula until the infant reaches term gestational age
  3. Express only when the breasts feel full
  4. Delay all milk expression until the infant can latch

Explanation

Early and frequent expression, starting within the first 1 to 2 hours and continuing at least 8 times in 24 hours, establishes and protects milk supply when the infant cannot feed directly. Waiting for fullness or for the infant to mature reduces supply. Formula supplementation is not the default when maternal milk is available.

Question 37Normal Breastfeeding and Lactation Management

Which statement about the let-down reflex is correct?

  1. It is entirely under conscious control and can be started at will
  2. It can be inhibited by stress or pain and facilitated by relaxation and warmth Correct answer.
  3. It is unrelated to the infant's suckling stimulus
  4. It occurs only during the first feed of the day

Explanation

The let-down reflex is a neuroendocrine response that can be inhibited by stress, pain, or anxiety and facilitated by relaxation, warmth, and the infant's suckling. It is not fully under conscious control and can occur multiple times per feed. Suckling is a key stimulus.

Question 38Normal Breastfeeding and Lactation Management

A mother reports that her 4-month-old has begun to feed more frequently and seems less satisfied in the evenings. Which response is most appropriate?

  1. Recommend rigid 4-hour scheduling to increase supply
  2. Suggest supplementing with water between feeds
  3. Reassure that this is consistent with a growth spurt and encourage continued responsive feeding Correct answer.
  4. Advise weaning to formula because supply is failing

Explanation

Increased feeding frequency around growth spurts is normal and typically increases supply through demand. Responsive feeding supports this process. Rigid scheduling and water supplementation are not recommended and can undermine supply or safety.

Question 39Normal Breastfeeding and Lactation Management

Which of the following is a recognized sign of an effective latch?

  1. The mother experiences sharp pain throughout the feed
  2. The infant takes a large mouthful of breast with lips flanged outward and chin pressed to the breast Correct answer.
  3. The infant's lips are curled inward and the chin is far from the breast
  4. Feeding is accompanied by clicking sounds throughout

Explanation

An effective latch involves a wide gape with the infant taking a large mouthful, lips flanged outward, and the chin pressed into the breast. Clicking sounds and persistent pain suggest a shallow or ineffective latch. Curled-in lips indicate poor attachment.

Question 40Normal Breastfeeding and Lactation Management

A breastfeeding mother with a 2-month-old develops a tender, red, wedge-shaped area on one breast with fever of 38.6°C and flu-like symptoms. What is the most appropriate action?

  1. Stop breastfeeding on the affected side permanently
  2. Reduce fluid intake to decrease milk production
  3. Apply cold packs only and reassess in one week
  4. Continue breastfeeding and express, and seek prompt medical evaluation for possible mastitis Correct answer.

Explanation

Fever with a focal red, tender area suggests mastitis; continued milk removal plus prompt medical evaluation for possible antibiotics is standard. Abrupt cessation worsens congestion. Cold packs alone and fluid restriction are not adequate management.

Question 41Normal Breastfeeding and Lactation Management

Which of the following best describes the role of prolactin in lactation?

  1. It causes uterine involution after birth
  2. It triggers the onset of labor
  3. It promotes milk synthesis in the alveolar cells Correct answer.
  4. It stimulates milk ejection from the alveoli

Explanation

Prolactin from the anterior pituitary stimulates alveolar cells to synthesize milk. Milk ejection is driven by oxytocin. Uterine involution is influenced by oxytocin, and labor onset involves other hormonal signals.

Question 42Normal Breastfeeding and Lactation Management

A mother with flat nipples is struggling to latch her newborn. Which intervention is most appropriate initially?

  1. Recommend immediate use of a nipple shield for all feeds
  2. Advise weaning to bottle-feeding
  3. Teach techniques such as breast sandwiching and try different positions to draw out the nipple Correct answer.
  4. Delay all feeding until the nipples protrude spontaneously

Explanation

Initial management of flat nipples includes shaping the breast (sandwiching) and trying positions that help the infant grasp tissue. Nipple shields may be used selectively with guidance but are not the universal first step. Weaning and delaying feeds are inappropriate.

Question 43Normal Breastfeeding and Lactation Management

Which statement about the composition of mature human milk is correct?

  1. It has a constant composition throughout a single feed
  2. It contains no immunological factors once mature
  3. Fore-milk is higher in fat than hind-milk
  4. Hind-milk contains more fat than fore-milk Correct answer.

Explanation

Fat content increases during a feed, so hind-milk is richer in fat than fore-milk. Mature milk still contains immunological factors. Composition varies within and across feeds.

Question 44Normal Breastfeeding and Lactation Management

A mother returning to work asks how to maintain her milk supply while separated from her infant. Which plan is most appropriate?

  1. Pump only once daily at the end of the workday
  2. Pump at intervals approximating the infant's feeding schedule and store the milk safely Correct answer.
  3. Skip pumping and rely on formula during the workday
  4. Pump only when breasts become painful

Explanation

Pumping at intervals that mirror the infant's feeding pattern maintains stimulation and supply, and safe storage preserves milk quality. Infrequent or pain-driven pumping leads to declining supply. Formula reliance without pumping reduces stimulation.

Question 45Normal Breastfeeding and Lactation Management

Which of the following is an appropriate storage guideline for freshly expressed human milk at room temperature?

  1. Up to 4 hours at room temperature is generally acceptable Correct answer.
  2. Up to 24 hours at room temperature is generally acceptable
  3. It must be discarded immediately
  4. It can be stored at room temperature indefinitely

Explanation

Freshly expressed milk is generally considered safe at room temperature for up to about 4 hours. Longer room-temperature storage increases bacterial growth risk. Immediate discarding and indefinite storage are incorrect.

Question 46Normal Breastfeeding and Lactation Management

A newborn is jaundiced at 48 hours and is sleepy at the breast. Which action best supports both feeding and jaundice management?

  1. Supplement with water to flush bilirubin
  2. Stop breastfeeding until jaundice resolves
  3. Encourage frequent feeds, waking the infant if needed, and monitor output and weight Correct answer.
  4. Restrict feeds to allow the infant to sleep

Explanation

Frequent feeding promotes bilirubin excretion through stool and supports intake in a sleepy infant. Water does not aid bilirubin clearance and can displace milk. Stopping breastfeeding is not indicated for typical jaundice.

Question 47Normal Breastfeeding and Lactation Management

Which statement about skin-to-skin contact immediately after birth is correct?

  1. It should be delayed until the first feed is completed
  2. It is only beneficial for preterm infants
  3. It has no effect on breastfeeding initiation
  4. It supports thermoregulation and early breastfeeding initiation Correct answer.

Explanation

Skin-to-skin contact supports thermoregulation, stabilizes the newborn, and facilitates early breastfeeding initiation. It is beneficial for term and preterm infants and is not delayed until after feeding.

Question 48Normal Breastfeeding and Lactation Management

A mother reports nipple pain that begins at latch and improves during the feed. Which cause is most likely?

  1. Shallow latch or poor attachment Correct answer.
  2. Insufficient glandular tissue
  3. Mastitis
  4. Candida infection

Explanation

Pain at latch that improves as the feed progresses is typical of a shallow latch or poor attachment. Candida pain often persists between feeds and is burning. Mastitis presents with focal redness and systemic symptoms.

Question 49Normal Breastfeeding and Lactation Management

Which of the following best describes the recommended approach to introducing a bottle to a breastfed infant?

  1. Delay introduction until breastfeeding is well established, often around 3 to 4 weeks Correct answer.
  2. Introduce a bottle in the first week to prevent refusal
  3. Introduce a bottle only after 6 months
  4. Avoid bottles entirely regardless of maternal needs

Explanation

Delaying bottle introduction until breastfeeding is established, often around 3 to 4 weeks, reduces the risk of nipple confusion and supports supply. Early introduction and rigid avoidance extremes are not universally recommended.

Question 50Normal Breastfeeding and Lactation Management

A mother asks whether she can breastfeed while taking a common analgesic. What is the most appropriate response?

  1. Check a reliable lactation safety resource and individualize the decision Correct answer.
  2. Advise stopping breastfeeding for all medications
  3. Tell her any medication is safe without checking
  4. Recommend avoiding all analgesics regardless of need

Explanation

Many analgesics are compatible with breastfeeding, but decisions should be individualized using reliable lactation safety resources. Blanket cessation or blanket reassurance is inappropriate.
