Question

Patient in respiratory distress, BP 70/50 mm Hg, with a lead II ECG showing a persistent tachyarrhythmia. What is the most appropriate intervention?

A) Administer nitroglycerin
B) Initiate synchronized cardioversion
C) Administer a beta-blocker
D) Perform chest compressions

Answer 1

Synchronized cardioversion is the most appropriate and urgent intervention for a patient exhibiting respiratory distress, hypotension, and persistent tachyarrhythmia.

Step-by-step explanation:

The most appropriate intervention for a patient in respiratory distress with a blood pressure of 70/50 mm Hg and a persistent tachyarrhythmia on a lead II ECG is Initiate synchronized cardioversion (Option B). Given the urgency, a beta-blocker may be too slow in action and could potentially worsen hypotension, nitroglycerin is contraindicated due to the low blood pressure and risk of further hypotension, and chest compressions are only necessary if the patient is in cardiac arrest (no pulse). Synchronized cardioversion is used as urgent treatment for those who have severe symptoms from an arrhythmia, which in this situation applies due to the presence of respiratory distress and hypotension.
