CFRN MCQ 3

Question 1

A flight nurse is transporting a patient on a norepinephrine drip at 0.1 mcg/kg/min. The patient weighs 80 kg. At what rate (mL/hr) should the pump be set if norepinephrine is mixed as 4 mg in 250 mL NS?

Accepted Answer

12 mL/hr

Answer

Concentration = 16 mcg/mL; dose = 0.1 × 80 = 8 mcg/min = 480 mcg/hr; 480 ÷ 16 = 30 mL/hr — wait, 4mg/250mL = 16mcg/mL; 8mcg/min × 60 = 480mcg/hr; 480/16 = 30 mL/hr.

Question 2

Which intervention is the HIGHEST priority when managing a patient with a GCS of 6 and suspected herniation syndrome during flight?

Accepted Answer

Elevate head of stretcher to 30 degrees and maintain normocapnia

Answer

HOB elevation and maintaining normocapnia (PaCO2 35–40) is the first-line ICP management; hyperventilation is reserved for impending herniation.

Question 3

During a neonatal transport, the flight nurse notes the neonate's oxygen saturation is 72% in the first 3 minutes of life. What is the MOST appropriate response?

Accepted Answer

Begin supplemental oxygen via blow-by and titrate to SpO2 targets for age in minutes

Answer

NRP guidelines specify SpO2 targets that gradually rise from 60–65% at 1 min to 85–95% at 10 min; titrating supplemental O2 is appropriate.

Question 4

A patient is in SVT with a heart rate of 190 bpm and is hemodynamically stable. After vagal maneuvers fail, which pharmacological intervention should be administered FIRST?

Accepted Answer

Adenosine 6 mg rapid IV push followed by saline flush

Answer

Adenosine 6 mg rapid IV push is first-line pharmacological treatment for stable SVT per ACLS guidelines.

Question 5

A 68-year-old patient develops hypotension after receiving morphine for rib fracture pain during transport. Which action should the flight nurse take FIRST?

Accepted Answer

Give a 250 mL crystalloid bolus and reassess

Answer

Morphine-induced histamine release can cause vasodilation; a fluid bolus addresses relative hypovolemia before reversal agents.
