CMT CMT Emergency Response and ACLS Protocols 2

Question 1

The H's and T's mnemonic in ACLS represents reversible causes of cardiac arrest. Which of the following is NOT one of the H's?

Accepted Answer

Hypertension

Answer

The H's of cardiac arrest are Hypovolemia, Hypoxia, Hydrogen ion (acidosis), Hypo/Hyperkalemia, and Hypothermia — Hypertension is not included.

Question 2

A patient in the telemetry unit develops a rapid wide-complex tachycardia at 180 bpm with a blood pressure of 60/40 mmHg. The CMT's priority notification should emphasize:

Accepted Answer

Hemodynamic instability requiring immediate bedside response

Answer

Hemodynamic instability with a dangerous tachyarrhythmia is a critical emergency requiring immediate bedside response; unstable patients may need cardioversion.

Question 3

Synchronized cardioversion is used instead of defibrillation for which arrhythmia?

Accepted Answer

Unstable atrial flutter with a pulse

Answer

Synchronized cardioversion delivers a shock timed to the QRS complex and is used for organized rhythms with a pulse, such as unstable SVT or atrial flutter.

Question 4

When transcutaneous pacing is initiated for complete heart block, the CMT confirms effective capture by:

Accepted Answer

Observing pacing spikes followed by wide QRS complexes plus a palpable pulse confirmed by bedside staff

Answer

Electrical capture is confirmed by pacing spikes followed by wide QRS complexes, and mechanical capture is confirmed by a palpable pulse.

Question 5

What does a post-resuscitation 12-lead ECG primarily evaluate for after return of spontaneous circulation (ROSC)?

Accepted Answer

ST elevation indicating STEMI requiring urgent cath lab activation

Answer

Post-ROSC 12-lead ECG is essential to detect STEMI, as myocardial infarction is a leading cause of cardiac arrest requiring emergent reperfusion.
