1. A postpartum patient is 4 hours post-vaginal delivery. Upon assessment, the
nurse finds the fundus is firm, midline, and two fingerbreadths below the
, umbilicus, but the patient is experiencing heavy vaginal bleeding with numerous
small clots. What is the most likely cause?
A. Uterine atony
B. Retained placental fragments
C. Cervical or vaginal laceration
D. Disseminated intravascular coagulation
🟢 Correct answer: C. Cervical or vaginal laceration
🔴 RATIONALE: When the fundus remains firm and midline but heavy bleeding
persists, it suggests a laceration of the birth canal rather than uterine atony. Atony
would result in a "boggy" or soft uterus.
2. A newborn at 2 hours of age has a respiratory rate of 72 breaths per minute,
mild intercostal retractions, and occasional grunting. The infant was born via
elective Cesarean section at 38 weeks. What is the most probable diagnosis?
A. Respiratory distress syndrome
B. Transient tachypnea of the newborn
C. Meconium aspiration syndrome
D. Persistent pulmonary hypertension
,🟢 Correct answer: B. Transient tachypnea of the newborn
🔴 RATIONALE: Transient tachypnea of the newborn (TTN) is common in infants
born via C-section due to the lack of "thoracic squeeze" that helps clear fetal lung
fluid. It typically presents with mild respiratory distress shortly after birth.
3. Which of the following is a primary legal requirement when a nurse suspects a
colleague of diverting narcotics in the maternal-newborn unit?
A. Confront the colleague directly
B. Report the suspicion to the nurse manager or supervisor
C. Document the colleague's behavior for 30 days before reporting
D. Ignore the situation unless patient harm occurs
🟢 Correct answer: B. Report the suspicion to the nurse manager or supervisor
🔴 RATIONALE: Professional standards and legal regulations require nurses to
report suspected impairment or diversion to their immediate supervisor to ensure
patient safety and facilitate appropriate intervention.
4. A mother who is breastfeeding asks how to tell if her 4-day-old infant is getting
enough milk. Which indicator is most reliable?
, A. The infant sleeps for 4 hours between feedings
B. The infant has at least 6 to 8 wet diapers in 24 hours
C. The mother's breasts feel soft after every feeding
D. The infant stops crying immediately after nursing
🟢 Correct answer: B. The infant has at least 6 to 8 wet diapers in 24 hours
🔴 RATIONALE: Objective measures such as the number of wet diapers (typically 6-
8 per day by day 4) and yellow, seedy stools are the most reliable indicators of
adequate intake in a breastfed neonate.
5. During the initial assessment of a newborn, the nurse notes a localized swelling
on the head that does not cross the suture lines. This is documented as:
A. Caput succedaneum
B. Subgaleal hemorrhage
C. Cephalohematoma
D. Encephalocele
🟢 Correct answer: C. Cephalohematoma
🔴 RATIONALE: A cephalohematoma is a collection of blood between the
periosteum and the skull bone; because it is confined by the periosteum, it does not
