Question 1

A 3-year-old weighing 14 kg requires a weight-based dopamine infusion at 5 mcg/kg/min. Using the rule of 6, how many mg of dopamine should be added to 100 mL of D5W?

Accepted Answer

84 mg

Answer

Rule of 6: weight (kg) × 6 = mg added to 100 mL; 14 × 6 = 84 mg, giving 1 mcg/kg/min per 1 mL/hr.

Question 2

During neonatal transport, a 28-week premature infant develops bradycardia to 80 bpm with oxygen saturation dropping to 75%. The FIRST intervention should be:

Accepted Answer

Provide positive pressure ventilation with 100% oxygen

Answer

Neonatal bradycardia is almost always hypoxia-driven, so the first step is to ensure adequate ventilation with PPV.

Question 3

A 6-week-old infant presents with bilious vomiting and abdominal distension. Which diagnosis should the flight nurse prioritize as most life-threatening?

Accepted Answer

Midgut volvulus

Answer

Midgut volvulus causes rapid intestinal ischemia and can be fatal within hours if untreated, making it the most immediately life-threatening cause of bilious vomiting in an infant.

Question 4

When securing a pediatric endotracheal tube in flight, the flight nurse should verify correct depth using which landmark formula?

Accepted Answer

3 × ETT internal diameter (mm) at the lip

Answer

Tube depth (cm at lip) = 3 × internal diameter of the ETT is a reliable bedside formula for pediatric patients.

Question 5

A 10 kg toddler in hemorrhagic shock receives an initial fluid bolus of 20 mL/kg NS. After two boluses with minimal improvement, what is the next most appropriate intervention?

Accepted Answer

Administer 10 mL/kg packed red blood cells

Answer

After two crystalloid boluses with inadequate response in hemorrhagic shock, early transfusion with pRBC at 10 mL/kg is indicated.
