Immediate Defibrillation

Synchronized Cardioversion

Perform CPR

Repeat electrocardiogram (ECG)

Answer and Explanation

The Correct Answer is A

A. Defibrillation is the priority intervention for pulseless ventricular tachycardia, as it can restore a normal rhythm. It should be performed as soon as possible.
B. Synchronized cardioversion is used for hemodynamically unstable tachyarrhythmias with a pulse, not for pulseless V-Tach.
C. CPR should be initiated if a defibrillator is not immediately available, but defibrillation is the definitive treatment.
D. Repeating an ECG does not address the immediate life-threatening situation.

Correct Answer is A

Explanation

A. In a hypertensive emergency, the goal is to reduce blood pressure gradually over 24 to 48 hours to prevent organ damage while avoiding excessive drops that could cause ischemia.
B. Rapid reduction of blood pressure over a few hours can lead to organ hypoperfusion and ischemic complications, such as stroke or acute kidney injury.
C. A 50% reduction in the first hour is too aggressive and may result in severe adverse effects such as cerebral or myocardial ischemia. The recommended initial reduction is no more than 25% in the first hour.
D. Treating hypertension based solely on symptoms is inappropriate, as some patients may be asymptomatic despite dangerously high blood pressure. The focus is on preventing target organ damage.

A. Prolonged PR interval B. Presence of a U wave C. Peaked T waves D. Elevated ST segment

Correct Answer is C

Explanation

A. A prolonged PR interval can be seen in hyperkalemia but is not as characteristic as peaked T waves.
B. A U wave is typically seen in hypokalemia, not hyperkalemia.
C. Peaked T waves are a hallmark ECG finding in hyperkalemia and occur due to increased repolarization speed.
D. ST segment elevation is more commonly associated with myocardial infarction rather than hyperkalemia.
