Question 1: A postpartum client who is Rh-negative and has an Rh-positive
newborn is scheduled to receive Rh(D) immune globulin. The nurse
understands that this medication is most effective when administered within
what specific timeframe after delivery to prevent maternal sensitization?
A. 24 hours
B. 48 hours
C. 72 hours
D. 96 hours
CORRECT ANSWER: C. 72 hours
Rationale: Rh(D) immune globulin (RhoGAM) is most effective when administered
within 72 hours of delivery. While it can be given up to 28 days postpartum, the
standard of care and maximum efficacy is achieved within this 72-hour window to
prevent the mother's immune system from producing anti-Rh antibodies against fetal
Rh-positive erythrocytes that may have entered her circulation during delivery.
Question 2: A nurse is assessing a newborn who is 12 hours old and notes a
respiratory rate of 68 breaths per minute with mild grunting. Which of the
following actions should the nurse take first?
A. Notify the healthcare provider immediately
B. Continue routine monitoring as this is expected
C. Place the newborn in a prone position
D. Administer oxygen via hood at 2 L/min
CORRECT ANSWER: A. Notify the healthcare provider immediately
Rationale: A respiratory rate of 68 breaths per minute with grunting in a 12-hour-old
newborn is above the normal range (30-60 breaths/min) and indicates potential
respiratory distress. Grunting is a sign of early respiratory compromise. The nurse
should notify the healthcare provider immediately for further evaluation while
continuing to monitor the newborn's oxygenation and vital signs.
,Question 3: A postpartum mother reports that her breasts feel full, firm, and
tender on the third day after delivery. She is bottle-feeding her infant. Which of
the following nursing interventions is most appropriate to alleviate her
discomfort?
A. Apply warm compresses to the breasts before feeding
B. Express small amounts of milk to relieve pressure
C. Administer a prescribed diuretic to reduce fluid retention
D. Encourage the mother to wear a tight-fitting bra and apply ice packs
CORRECT ANSWER: D. Encourage the mother to wear a tight-fitting bra and
apply ice packs
Rationale: For a mother who is bottle-feeding and experiencing engorgement,
interventions should suppress lactation and milk production. A tight-fitting bra provides
support, while ice packs decrease vasodilation and reduce swelling and discomfort.
Warm compresses and expressing milk would stimulate further milk production, which
is not desired for a mother who is not breastfeeding.
Question 4: The nurse is assessing a newborn's gestational age using the
Ballard Scale. Which physical characteristic is most indicative of a full-term
newborn?
A. Abundant lanugo covering the back and shoulders
B. Plantar creases that cover the entire sole of the foot
C. Pinna of the ear that is soft and folds easily
D. Breast tissue measuring less than 2 mm in diameter
CORRECT ANSWER: B. Plantar creases that cover the entire sole of the foot
Rationale: In a full-term newborn (37-42 weeks gestation), plantar creases are
expected to cover the entire sole of the foot. Abundant lanugo is more characteristic of
preterm infants. A soft, foldable pinna and minimal breast tissue are also signs of
prematurity. As gestational age increases, the ear cartilage becomes more rigid, and
breast tissue increases in size.
Question 5: A postpartum client who had a vaginal delivery 4 hours ago has a
continuous trickle of bright red blood from the vagina and a firm fundus at the
umbilicus. What condition should the nurse suspect first?
A. Uterine atony
B. Retained placental fragments
C. Vaginal or cervical laceration
D. Normal lochia rubra
,CORRECT ANSWER: C. Vaginal or cervical laceration
Rationale: A continuous trickle of bright red blood despite a firm fundus is a classic
sign of a vaginal or cervical laceration. The firm fundus indicates the uterus is
contracting effectively, ruling out uterine atony as the primary cause of bleeding. Bright
red blood (not dark or clotted) and a continuous flow suggest active bleeding from a
lower genital tract injury. Normal lochia rubra is dark red and occurs in moderate
amounts, not as a continuous trickle.
Question 6: The nurse is teaching a postpartum client about signs of infection.
Which statement by the client indicates a need for further teaching?
A. "I should call my doctor if my incision becomes red and warm."
B. "A fever of 99.5°F (37.5°C) is normal for the first 24 hours."
C. "I will monitor my lochia for a foul odor."
D. "If I have chills, I should contact my provider."
CORRECT ANSWER: B. "A fever of 99.5°F (37.5°C) is normal for the first 24
hours."
Rationale: While a slight temperature elevation can occur after delivery due to
dehydration from labor, a fever of 100.4°F (38°C) or higher on two occasions after the
first 24 hours is considered a sign of postpartum infection. A temperature of 99.5°F may
be acceptable within the first 24 hours, but stating it is "normal" implies that a fever is
not a concern, which is an incorrect generalization. Any persistent fever should be
reported.
Question 7: A newborn is receiving phototherapy for hyperbilirubinemia.
Which nursing intervention is essential to ensure the safety and effectiveness
of the therapy?
A. Position the newborn supine for the entire treatment
B. Cover the newborn's eyes with opaque shields
C. Apply lotion to the newborn's skin to prevent drying
D. Encourage feeding every 6 hours to promote bilirubin excretion
CORRECT ANSWER: B. Cover the newborn's eyes with opaque shields
Rationale: The essential safety intervention during phototherapy is to cover the
newborn's eyes with opaque eye shields to prevent retinal damage from the high-
intensity light. The newborn's position should be changed frequently to expose all skin
surfaces to the light. Lotions should not be used as they can absorb heat and cause
burns. Feeding should be encouraged every 2-3 hours to promote bowel movements,
which excrete bilirubin.
, Question 8: A postpartum client is 6 hours post-cesarean section and has an
indwelling urinary catheter. The nurse notes that the urine output for the past
3 hours is 20 mL/hour. What is the priority nursing action?
A. Increase the IV fluid rate
B. Assess the catheter for kinks or obstruction
C. Document the finding as normal
D. Administer a diuretic as prescribed
CORRECT ANSWER: B. Assess the catheter for kinks or obstruction
Rationale: A urine output of less than 30 mL/hour indicates oliguria. The priority
action is to assess the urinary catheter system for kinks, obstruction, or proper
placement to ensure the bladder is emptying appropriately. This is a basic nursing
intervention that should be performed before increasing IV fluids or administering
diuretics. Documentation is important, but assessment is the priority.
Question 9: The nurse is assessing a newborn's reflexes. Which finding would
be considered abnormal and require further evaluation?
A. The newborn turns head toward the cheek when stroked
B. The newborn's toes curl downward when the sole is stroked
C. The newborn extends the arms and legs when startled
D. The newborn's foot bends backward when pressure is applied to the ball of the foot
CORRECT ANSWER: B. The newborn's toes curl downward when the sole is
stroked
Rationale: When the sole of the foot is stroked, the expected response is a Babinski
reflex, where the toes fan upward and outward. Toes curling downward is an abnormal
finding and may indicate a neurological issue. The other options describe expected
reflexes: rooting (turning toward the cheek), Moro (startle response), and a normal
response to pressure on the ball of the foot.
Question 10: A postpartum mother who is breastfeeding reports severe nipple
pain and cracks. The nurse observes that the infant's lips are turned inward
during feeding. What is the most likely cause of the mother's discomfort?
A. Engorgement
B. Thrush
C. Improper latch
D. Mastitis
CORRECT ANSWER: C. Improper latch
Rationale: An improper latch, indicated by the infant's lips being turned inward
(instead of flanged outward), is the most common cause of nipple pain, trauma, and
