,NR 328 Pediatric Cardiology & Assessment (Week 3) 2026/2027 UPDATE – Chamberlain
College
1. A 2-week-old infant is diagnosed with Transposition of the Great Arteries (TGA). Which
medication should the nurse prioritize to maintain ductal patency before surgical
intervention?
A. Indomethacin
B. Furosemide
C. Alprostadil (Prostaglandin E1)
D. Digoxin
Answer: C
Rationale: In cyanotic heart defects like TGA where blood mixing is essential for survival,
Prostaglandin E1 is administered to keep the ductus arteriosus open. Indomethacin is used
to close a PDA.
2. When assessing a child with Tetralogy of Fallot, the nurse notes increased cyanosis,
irritability, and tachypnea. What is the physiological basis for this ‘Tet spell’?
A. Sudden increase in systemic vascular resistance
B. Acute decrease in pulmonary vascular resistance
, C. Rapid closure of the ventricular septal defect
D. Spasm of the infundibular septum increasing right-to-left shunting
Answer: D
Rationale: Hypercyanotic spells are caused by an acute increase in right-to-left shunting,
often due to infundibular spasm or a decrease in systemic vascular resistance relative to
pulmonary resistance.
3. Which clinical finding is pathognomonic for a large Patent Ductus Arteriosus (PDA) in an
older infant?
A. Systolic ejection click at the left upper sternal border
B. Continuous machinery-like murmur below the left clavicle
C. Holosystolic murmur at the lower left sternal border
D. Diastolic decrescendo murmur at the aortic area
Answer: B
Rationale: The classic murmur of PDA is a continuous, machinery-like sound heard
throughout the cardiac cycle at the left infraclavicular area.
4. A child is admitted with suspected Kawasaki Disease. Which assessment finding is most
characteristic of the acute phase?
A. Desquamation of the hands and feet
B. Coronary artery aneurysm formation
