Question 1

An infant presents with a heart rate of 55 bpm, poor perfusion, and decreased LOC despite oxygen therapy. The NEXT appropriate intervention is:

Accepted Answer

Chest compressions and prepare for IV/IO access

Answer

Symptomatic bradycardia with poor perfusion in an infant unresponsive to oxygenation requires immediate CPR and vascular access per pediatric guidelines.

Question 2

A patient with a known history of diabetes is found unresponsive. Blood glucose reads 28 mg/dL. No IV access can be established. The BEST alternative route for dextrose administration is:

Accepted Answer

Intraosseous (IO) access

Answer

When IV access fails, IO access allows rapid administration of dextrose in an unresponsive hypoglycemic patient.

Question 3

During endotracheal intubation, the colorimetric CO2 detector shows a PURPLE color after 6 ventilations. This MOST likely indicates:

Accepted Answer

Esophageal intubation

Answer

A persistent purple (negative) reading on a colorimetric CO2 detector after 6 ventilations strongly suggests esophageal intubation requiring immediate tube removal.

Question 4

A 70-year-old patient presents with sudden-onset tearing chest pain radiating to the back between the shoulder blades. Blood pressure is 190/110 in the right arm and 150/90 in the left arm. You MOST suspect:

Accepted Answer

Aortic dissection

Answer

Tearing back pain with a blood pressure differential between arms is a classic presentation of aortic dissection requiring rapid transport.

Question 5

Which of the following is the CORRECT compression-to-ventilation ratio for two-rescuer CPR on a 4-year-old child without an advanced airway?

Accepted Answer

15:2

Answer

Two-rescuer pediatric CPR without an advanced airway uses a 15:2 ratio to provide more frequent ventilations than in adult CPR.
