CPR Emergency Medical Procedures & Protocols 3

Question 1

A trauma patient has a systolic BP of 70 mmHg, heart rate of 130, and is unresponsive. Which fluid resuscitation strategy is preferred in penetrating torso trauma?

Accepted Answer

Permissive hypotension targeting SBP 80-90 mmHg

Answer

Permissive hypotension (targeting SBP 80-90 mmHg) is preferred in penetrating torso trauma to avoid diluting clotting factors while maintaining perfusion.

Question 2

Which finding on a 12-lead ECG is MOST indicative of an ST-elevation myocardial infarction (STEMI) requiring immediate cath lab activation?

Accepted Answer

ST elevation ≥1 mm in two or more contiguous leads

Answer

ST elevation ≥1 mm in two or more contiguous leads is the hallmark ECG criterion for STEMI requiring emergent reperfusion therapy.

Question 3

During a high-priority trauma transport, a patient's SpO2 drops from 98% to 82% with diminished breath sounds on the right. What is the MOST likely diagnosis?

Accepted Answer

Right-sided tension pneumothorax

Answer

Unilateral diminished breath sounds with acute SpO2 decline in a trauma patient is tension pneumothorax until proven otherwise.

Question 4

What is the correct dose of epinephrine administered during adult cardiac arrest per current AHA ACLS protocol?

Accepted Answer

1 mg IV every 3-5 minutes

Answer

Epinephrine 1 mg IV is given every 3-5 minutes during adult cardiac arrest as the primary vasopressor per AHA ACLS guidelines.

Question 5

A 6-year-old child (22 kg) requires IV fluid resuscitation for dehydration. What is the correct initial bolus volume?

Accepted Answer

220 mL normal saline

Answer

The standard pediatric fluid bolus is 20 mL/kg, so a 22 kg child receives 440 mL — but the initial safe bolus is commonly administered as 10-20 mL/kg; 20 mL/kg = 440 mL.
