A nurse is caring for a client who reports shortness of breath and heart palpitations. An ECG confirms the client is experiencing ventricular tachycardia (VT). The nurse palpates a rapid carotid pulse with a blood pressure of 70/30, and the client reports feeling dizzy. The nurse should anticipate the need for which priority action?

Initiate external pacing.

Initiate CPR.

Defibrillation.

Synchronized cardioversion.

Answer and Explanation

The Correct Answer is D

A. External pacing is not indicated for ventricular tachycardia with a pulse. Pacing is typically used for bradyarrhythmias.
B. CPR is only necessary if the client is pulseless. Since the client has a pulse, a more appropriate intervention is needed.
C. Defibrillation is used for pulseless VT or ventricular fibrillation, but this client has a pulse and is symptomatic.
D. Synchronized cardioversion is the appropriate intervention for unstable ventricular tachycardia with a pulse. The shock is synchronized to the R wave to prevent inducing ventricular fibrillation.

Correct Answer is A

Explanation

A. Digoxin is a positive inotropic agent, meaning it increases the force of cardiac contractions. This helps improve cardiac output in patients with heart failure.
B. Digoxin does not decrease the force of contractions; instead, it strengthens them, making it beneficial for heart failure treatment.
C. Digoxin is commonly used in heart failure management, particularly in cases of systolic dysfunction or atrial fibrillation.
D. Digoxin decreases heart rate by slowing conduction through the atrioventricular (AV) node, making it useful in atrial fibrillation, but its primary benefit in heart failure is increasing contractility.

A. Nitroglycerin B. Atorvastatin C. Metformin D. Carvedilol

Correct Answer is C

Explanation

A. Nitroglycerin is used for angina and does not interact with contrast material or increase the risk of acute kidney injury.
B. Atorvastatin, a statin medication, is not known to interact with contrast dye or cause kidney injury in this context.
C. Metformin is contraindicated with contrast dye because it can increase the risk of lactic acidosis, especially in clients with impaired renal function. It should be withheld before and after the procedure to prevent complications.
D. Carvedilol, a beta-blocker, is used for blood pressure and heart failure management but does not interfere with contrast dye.
