Question 1Choose one

A 4-year-old child with tricuspid atresia is admitted to the pediatric intensive care unit following an extracardiac Fontan completion. To maintain adequate cardiac output in this patient, which hemodynamic principle must guide the nurse's priority assessments and interventions?

Question 2Choose one

A 5-month-old infant with hypoplastic left heart syndrome is admitted to the pediatric intensive care unit following a stage II bidirectional Glenn procedure (superior vena cava to right pulmonary artery anastomosis). The child is mechanically ventilated on pressure control ventilation. Invasive arterial blood pressure is 68/42 mm Hg (mean 50 mm Hg), central venous pressure (CVP) transduced from the internal jugular line is 18 mm Hg, and pulse oximetry is 81% on an FiO2 of 0.35. Over the past hour, the nurse observes that somatic near-infrared spectroscopy (NIRS) remains stable at 65%, but cerebral NIRS has dropped progressively from 62% to 41%. The infant is noted to have facial plethora and non-reactive periorbital edema. Which postoperative complication should the nurse suspect as the primary cause of this presentation?

Question 3Choose one

In pediatric patients, which electrocardiographic measurement criteria differentiates a wide-complex tachycardia from a narrow-complex tachycardia?

Question 4Choose 2

An alert 6-year-old child presents to the pediatric intensive care unit with sudden-onset palpitations and lightheadedness. The bedside cardiac monitor shows a regular, narrow-complex tachycardia at 230 beats/min with absent P waves. The patient's blood pressure is 96/60 mm Hg, capillary refill is 2 seconds, and peripheral pulses are strong. Which TWO initial interventions are appropriate for this hemodynamically stable supraventricular tachycardia? (Select TWO)

Question 5Choose one

A 12-year-old adolescent with a known history of Wolff-Parkinson-White (WPW) syndrome develops atrial fibrillation with rapid ventricular response and an irregularly irregular wide QRS morphology on the monitor. The patient remains conscious with a blood pressure of 104/68 mm Hg. Which medication is contraindicated because it accelerates conduction down the accessory pathway and risks precipitating ventricular fibrillation?

Question 6Choose one

A 4-year-old child with septic shock and worsening encephalopathy requires rapid sequence intubation (RSI). When preparing the child for endotracheal intubation, which evidence-based practice aligns with current pediatric resuscitation standards?
