Acute Care Nurse Practitioner Cardiovascular Emergencies and Arrhythmia Management

Question 1

A patient presents with acute anterior STEMI. What is the preferred reperfusion strategy when PCI can be performed within 90 minutes?

Accepted Answer

Primary percutaneous coronary intervention (PCI)

Answer

Primary PCI is the preferred reperfusion strategy for STEMI when achievable within 90 minutes of first medical contact.

Question 2

Which ECG finding is diagnostic of ST-elevation myocardial infarction (STEMI) in two contiguous leads?

Accepted Answer

New LBBB or ST elevation ≥1 mm (≥2 mm in V1-V3)

Answer

STEMI is diagnosed by ST elevation ≥1 mm in two contiguous leads (≥2 mm in V1-V3) or new LBBB with ischemic symptoms.

Question 3

A patient with acute decompensated heart failure (ADHF) has an SpO₂ of 85% on room air and BP 150/90. Which is the MOST appropriate initial intervention?

Accepted Answer

Administer IV furosemide and apply NIPPV (BiPAP)

Answer

ADHF with hypoxia but intact blood pressure is best managed with diuresis (furosemide) and NIPPV to offload preload and improve oxygenation.

Question 4

Which arrhythmia is the MOST common cause of sudden cardiac arrest in adults?

Accepted Answer

Ventricular fibrillation

Answer

Ventricular fibrillation is the most common initial arrhythmia in sudden cardiac arrest, requiring immediate defibrillation.

Question 5

Which medication is indicated for rate control in atrial fibrillation with preserved ejection fraction and heart rate of 140 bpm?

Accepted Answer

Metoprolol IV

Answer

IV metoprolol (beta-blocker) is a first-line rate control agent for AF with preserved EF due to its rapid onset and reliability.
