Paramedics Exam Cardiology & Resuscitation 5

Question 1

A 70-year-old patient is in asystole. After confirming the rhythm in two leads, what is the correct immediate action?

Accepted Answer

Begin high-quality CPR and administer epinephrine

Answer

Asystole is a non-shockable rhythm; treatment is high-quality CPR with epinephrine every 3–5 minutes and search for reversible causes.

Question 2

Which of the following represents the correct interpretation of a QTc interval greater than 500 ms?

Accepted Answer

Significantly prolonged, associated with risk of Torsades de Pointes

Answer

A QTc >500 ms significantly increases the risk of Torsades de Pointes, a life-threatening polymorphic ventricular tachycardia.

Question 3

The treatment of choice for Torsades de Pointes (TdP) in a hemodynamically stable patient is:

Accepted Answer

Magnesium sulfate 1–2g IV over 5–20 minutes

Answer

Magnesium sulfate 1–2g IV is the first-line treatment for TdP as it suppresses the triggered activity causing the arrhythmia.

Question 4

Which statement about performing CPR on a pregnant patient in cardiac arrest is correct?

Accepted Answer

Manually displace the uterus to the left while performing standard CPR

Answer

Left uterine displacement (LUD) relieves aortocaval compression and improves venous return during CPR in pregnancy.

Question 5

A patient presents with bradycardia at 38 bpm, hypotension, and diaphoresis. Atropine 0.5mg IV fails to improve the rate. What is the next most appropriate intervention?

Accepted Answer

Initiate transcutaneous pacing

Answer

When atropine fails for symptomatic bradycardia, transcutaneous pacing is the next indicated intervention per ACLS guidelines.
