AEMT Pediatric and Geriatric Emergencies 2

Question 1

In pediatric cardiac arrest, the MOST common initial rhythm is:

Accepted Answer

Asystole or pulseless electrical activity (PEA)

Answer

Unlike adults, pediatric cardiac arrest usually results from respiratory failure leading to asystole or PEA, not primary arrhythmia.

Question 2

The epinephrine dose for pediatric cardiac arrest is:

Accepted Answer

0.01 mg/kg of 1:10,000 IV/IO

Answer

Pediatric epinephrine for cardiac arrest is 0.01 mg/kg of 1:10,000 solution IV/IO, repeated every 3–5 minutes.

Question 3

An elderly patient presents with confusion, fever of 101.8°F, and urinary symptoms. You should suspect:

Accepted Answer

Urinary tract infection (UTI) — a common cause of altered mental status in the elderly

Answer

UTIs frequently cause acute confusional states in geriatric patients because the aging brain is more vulnerable to systemic infection and inflammation.

Question 4

Which of the following physiologic changes in the elderly increases the risk of drug toxicity?

Accepted Answer

Decreased renal clearance and reduced hepatic metabolism

Answer

Aging reduces both kidney clearance and liver metabolism, causing drugs to accumulate to toxic levels more readily in elderly patients.

Question 5

A 7-year-old child (22 kg) needs defibrillation. What is the correct initial energy dose?

Accepted Answer

88 J (2 J/kg)

Answer

Pediatric defibrillation starts at 2 J/kg; for a 22 kg child that is 44 J, and subsequent shocks can be increased to 4 J/kg.
