  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?

    Answer: Hypertension

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

  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:

    Answer: Hemodynamic instability requiring immediate bedside response

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

  3. Synchronized cardioversion is used instead of defibrillation for which arrhythmia?

    Answer: Unstable atrial flutter with a pulse

    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.

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

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

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

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

    Answer: ST elevation indicating STEMI requiring urgent cath lab activation

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

  6. During a code, the CMT observes the rhythm change from VF to a slow wide-complex rhythm. The team should be informed that this may represent:

    Answer: Agonal rhythm (idioventricular) suggesting poor perfusion

    A slow wide-complex agonal rhythm following VF suggests a dying heart with poor perfusion, requiring continued aggressive resuscitation efforts.
