CERTIFICATION PREPARATION
1. A neonatal intensive care nurse is caring for an infant with a suspected congenital cardiac defect.
Which assessment finding should be reported immediately to the provider?
A. Heart rate of 148 beats/minute while awake
B. Mild acrocyanosis during crying
C. Oxygen saturation of 78% with increasing respiratory distress
D. Blood pressure of 62/38 mmHg
Correct Answer: C. Oxygen saturation of 78% with increasing respiratory distress
Rationale:
An oxygen saturation of 78% accompanied by worsening respiratory distress may indicate significant
cardiac compromise or inadequate systemic oxygen delivery and requires immediate intervention. A
heart rate of 148 beats/minute is within an expected neonatal range. Mild acrocyanosis may be
normal in newborns. The blood pressure listed may be acceptable depending on gestational age and
clinical status.
2. An infant with a ventricular septal defect is being monitored for signs of heart failure. Which
finding is most consistent with worsening cardiac workload?
A. Increased feeding tolerance
B. Tachypnea during feeding
C. Decreased urine specific gravity
D. Intermittent hiccups
Correct Answer: B. Tachypnea during feeding
Rationale:
Tachypnea during feeding is a classic sign of increased cardiac workload and developing heart failure
in infants with significant shunt lesions. Increased feeding tolerance suggests improvement. Urine
specific gravity is not a primary indicator of cardiac workload. Hiccups are generally unrelated to
heart failure progression.
3. A nurse is reviewing fetal circulation with a newly hired NICU nurse. Which structure normally
allows blood to bypass the fetal lungs?
A. Ductus arteriosus
B. Mitral valve
C. Pulmonary valve
D. Coronary sinus
Correct Answer: A. Ductus arteriosus
,Rationale:
The ductus arteriosus connects the pulmonary artery to the aorta, allowing blood to bypass the
nonfunctioning fetal lungs. The mitral and pulmonary valves regulate blood flow within the heart.
The coronary sinus drains venous blood from the myocardium.
4. Which intervention best reduces energy expenditure in a neonate with significant congenital
heart disease?
A. Increasing stimulation during wake periods
B. Frequent repositioning every 15 minutes
C. Clustered nursing care activities
D. Encouraging prolonged feeding sessions
Correct Answer: C. Clustered nursing care activities
Rationale:
Clustered care minimizes handling and conserves energy, reducing oxygen consumption. Excessive
stimulation, frequent repositioning, and prolonged feeding sessions can increase metabolic demands
and worsen cardiac stress.
5. A nurse notes weak femoral pulses and higher blood pressures in the upper extremities than the
lower extremities. Which condition should be suspected?
A. Patent ductus arteriosus
B. Atrial septal defect
C. Tetralogy of Fallot
D. Coarctation of the aorta
Correct Answer: D. Coarctation of the aorta
Rationale:
Coarctation of the aorta commonly causes diminished femoral pulses and a blood pressure gradient
between upper and lower extremities. The other defects do not typically produce this classic finding.
6. During administration of prostaglandin E1, which adverse effect requires close monitoring?
A. Hyperactivity
B. Apnea
C. Hypertension
D. Polyuria
Correct Answer: B. Apnea
Rationale:
Apnea is a well-recognized adverse effect of prostaglandin E1 therapy. Continuous respiratory
monitoring is essential. Hyperactivity, hypertension, and polyuria are not the primary concerns
associated with this medication.
7. A neonate develops sudden cyanosis and decreased oxygen saturation. What is the nurse's
priority action?
A. Document the event and continue observation
B. Increase environmental stimulation
, C. Assess airway, breathing, and circulation immediately
D. Delay assessment until the provider arrives
Correct Answer: C. Assess airway, breathing, and circulation immediately
Rationale:
Rapid assessment of airway, breathing, and circulation is the first priority during acute deterioration.
Waiting or delaying intervention may lead to worsening instability.
8. Which laboratory value is commonly elevated in neonates with chronic hypoxemia from
cyanotic heart disease?
A. Platelet count
B. Serum calcium
C. White blood cell count
D. Hematocrit
Correct Answer: D. Hematocrit
Rationale:
Chronic hypoxemia stimulates erythropoiesis, leading to elevated hematocrit levels. Platelets,
calcium, and white blood cells are not consistently elevated due to cyanotic heart disease alone.
9. A nurse caring for a postoperative cardiac infant notices decreased urine output. What is the
most appropriate interpretation?
A. Possible reduced cardiac output
B. Normal postoperative adaptation
C. Excessive nutrition intake
D. Improved renal function
Correct Answer: A. Possible reduced cardiac output
Rationale:
Reduced urine output may indicate decreased renal perfusion secondary to low cardiac output. It
requires prompt assessment and intervention. It is not automatically considered a normal adaptation.
10. Which assessment finding is most characteristic of congestive heart failure in a neonate?
A. Bradycardia during feeding
B. Poor weight gain
C. Increased alertness
D. Cool forehead only
Correct Answer: B. Poor weight gain
Rationale:
Poor weight gain results from increased metabolic demands and ineffective feeding associated with
heart failure. The other options are less characteristic indicators.
11. A nurse is preparing to administer furosemide. Which assessment should be prioritized before
administration?
A. Nail length
B. Fontanel shape only
