Clinical Judgment
Question 1: A postpartum nurse is assessing a client who is 12 hours post-vaginal delivery.
Which finding would be most indicative of a potential postpartum hemorrhage?
A. Heart rate of 80 bpm
B. Blood pressure of 120/80 mmHg
C. A firm, midline fundus at the umbilicus
D. A boggy fundus that does not respond to massage
CORRECT ANSWER: D. A boggy fundus that does not respond to massage
Rationale: A boggy uterus that is unresponsive to massage is a classic sign of uterine
atony, the most common cause of early postpartum hemorrhage. A firm fundus indicates
good uterine tone. Tachycardia and hypotension are late signs of hemorrhage, not early
indicators.
Question 2: A newborn is placed under a radiant warmer. Which nursing intervention is
essential to prevent hypothermia during the transition to an open crib?
A. Place the crib next to a window for sunlight.
B. Dress the newborn in a single layer of cotton.
C. Maintain the crib environment at 24°C (75°F).
D. Gradually decrease the warmer temperature while monitoring axillary temperature.
CORRECT ANSWER: D. Gradually decrease the warmer temperature while monitoring
axillary temperature.
Rationale: Gradual weaning from the radiant warmer allows the newborn to adapt to room
temperature. Axillary temperature is the most accurate and safe method for monitoring
core temperature in neonates. The crib should be placed away from drafts, not windows.
Question 3: A postpartum client reports severe perineal pain and a feeling of pressure 24
hours after a vaginal delivery with an episiotomy. What is the nurse's priority action?
A. Administer the prescribed PRN pain medication.
B. Apply an ice pack to the perineum.
C. Assess the perineum for hematoma formation.
D. Encourage the client to take a warm sitz bath.
CORRECT ANSWER: C. Assess the perineum for hematoma formation.
Rationale: Severe pain and pressure in the perineal area, especially after an episiotomy,
are key indicators of a hematoma. Assessment is the priority to identify this complication.
,While pain relief is important, it should not precede a thorough assessment for the
underlying cause.
Question 4: A nurse is providing discharge teaching to a new mother regarding newborn
safety. Which statement by the parent indicates a correct understanding of preventing
Sudden Infant Death Syndrome (SIDS)?
A. "I will place my baby on their side to sleep."
B. "I will use a firm mattress with a fitted sheet in the crib."
C. "I will place a soft blanket in the crib for comfort."
D. "I will keep the room warm to prevent chilling."
CORRECT ANSWER: B. "I will use a firm mattress with a fitted sheet in the crib."
Rationale: A firm mattress with a fitted sheet is a safe sleep environment. The American
Academy of Pediatrics recommends placing infants on their backs (not side) to sleep. Soft
bedding and overheating increase the risk of SIDS.
Question 5: A newborn is 24 hours old and has not passed meconium. Which condition
should the nurse suspect?
A. Jaundice
B. Caput succedaneum
C. Cephalohematoma
D. Meconium ileus
CORRECT ANSWER: D. Meconium ileus
Rationale: Meconium is usually passed within the first 24 to 48 hours of life. Failure to pass
meconium within this timeframe may indicate an intestinal obstruction, such as
meconium ileus, which is often associated with cystic fibrosis.
Question 6: A postpartum client diagnosed with preeclampsia is receiving magnesium
sulfate. Which assessment finding indicates magnesium toxicity?
A. Respiratory rate of 16 breaths per minute
B. Urine output of 40 mL/hr
C. Patellar reflex of 2+
D. Respiratory rate of 10 breaths per minute
CORRECT ANSWER: D. Respiratory rate of 10 breaths per minute
Rationale: Magnesium toxicity suppresses the central nervous system and can lead to
respiratory depression. A respiratory rate below 12 breaths per minute is a critical sign.
Urine output should be at least 30 mL/hr, and deep tendon reflexes should be 1+ to 2+.
Question 7: The nurse is assessing a newborn's gestational age using the Ballard score.
Which physical characteristic would indicate a more mature gestational age?
A. Sparse, fine lanugo
B. Prominent clitoris and labia majora
C. Flat areola with no bud
D. Faint red marks on the soles of the feet
,CORRECT ANSWER: A. Sparse, fine lanugo
Rationale: As gestational age increases, lanugo (fine hair) decreases and becomes sparse.
A prominent clitoris and flat areola are signs of prematurity. Creases on the soles of the
feet increase with maturity.
Question 8: A postpartum client is concerned about her breast milk supply. Which action is
most effective for establishing and maintaining an adequate milk supply?
A. Feed the newborn on a strict 4-hour schedule.
B. Supplement with water between feedings.
C. Breastfeed frequently and on demand.
D. Limit breastfeeding sessions to 5 minutes per side.
CORRECT ANSWER: C. Breastfeed frequently and on demand.
Rationale: Frequent and effective emptying of the breasts stimulates prolactin and
oxytocin release, which are essential for establishing and maintaining milk supply.
Demand feeding ensures the baby's needs are met and signals the body to produce more
milk.
Question 9: A nurse is caring for a newborn with jaundice. Which finding would warrant
immediate intervention?
A. Yellowing of the face
B. Yellowing of the chest
C. Yellowing of the abdomen
D. Yellowing of the palms and soles
CORRECT ANSWER: D. Yellowing of the palms and soles
Rationale: Jaundice that progresses to the palms and soles indicates significant
hyperbilirubinemia. This is a sign of pathologic jaundice and requires immediate
intervention to prevent kernicterus.
Question 10: Which medication is administered to a newborn immediately after birth to
prevent ophthalmia neonatorum?
A. Vitamin K
B. Hepatitis B vaccine
C. Erythromycin ophthalmic ointment
D. Naloxone
CORRECT ANSWER: C. Erythromycin ophthalmic ointment
Rationale: Erythromycin ophthalmic ointment is instilled in the newborn's eyes within 1
hour of birth to prevent ophthalmia neonatorum, an infection caused by Neisseria
gonorrhoeae or Chlamydia trachomatis acquired during delivery.
Question 11: A postpartum client is 48 hours post-cesarean birth. The nurse notes that the
client's lochia is moderate, rubra, and has a fleshy odor. What is the best interpretation of
this finding?
, A. A sign of infection
B. A normal finding
C. A sign of retained placental fragments
D. A sign of hemorrhage
CORRECT ANSWER: B. A normal finding
Rationale: Lochia rubra, which is dark red, is expected for the first 1 to 3 days postpartum.
A moderate amount with a fleshy odor is normal. A foul odor or large clots would suggest
infection or retained fragments.
Question 12: The nurse is educating a new mother on how to care for her newborn's
umbilical cord. Which statement indicates a need for further teaching?
A. "I will keep the cord clean and dry."
B. "I will fold the diaper below the cord stump."
C. "I will clean the base with alcohol after each diaper change."
D. "I will give my baby a tub bath until the cord falls off."
CORRECT ANSWER: D. "I will give my baby a tub bath until the cord falls off."
Rationale: The umbilical stump should remain dry and exposed to air to promote drying
and separation. Submerging the stump in water can delay separation and increase
infection risk. Sponge baths are recommended until the cord falls off.
Question 13: A newborn's heart rate is assessed at 100 bpm, with irregular breathing, a
weak cry, and some flexion of the extremities. What is the newborn's Apgar score based on
these findings?
A. 4
B. 5
C. 6
D. 7
CORRECT ANSWER: C. 6
Rationale: The Apgar score is based on five components: heart rate (100 bpm = 1 point),
respiratory effort (irregular = 1 point), muscle tone (some flexion = 1 point), reflex irritability
(weak cry = 1 point), and color (assumed acrocyanosis = 1 point). Total: 1+1+1+1+1 = 5?
Let's recalculate: HR 100 (1), RR irregular (1), Weak cry (1), Flexion (1), Color: if
acrocyanotic, it's 1. Total 5. However, if the scenario implies a higher score, but based on
the text, the correct answer is 5. Let's correct: HR 100=1, Irregular breathing=1, Weak
cry=1, Some flexion=1, Acrocyanosis=1 = 5. The answer is B. 5.
Question 14: A postpartum client asks the nurse about returning to her pre-pregnancy
weight. What is the most appropriate response regarding weight loss after delivery?
A. "You should lose all the weight within 2 weeks."
B. "Breastfeeding may help with weight loss, but it is gradual."
C. "You will need to start a strict diet immediately."
D. "Weight loss is not possible until you stop breastfeeding."
CORRECT ANSWER: B. "Breastfeeding may help with weight loss, but it is gradual."
