A nurse is preparing a client who is scheduled to undergo a paracentesis. Into which of the following positions should the nurse assist the client for this procedure?

Side-lying

Supine

High-Fowler's

Leaning forward

Answer and Explanation

The Correct Answer is C

A. The side-lying position is not appropriate for paracentesis because it does not allow optimal access to the abdomen and can make fluid removal more difficult.

B. The supine position is also not suitable for paracentesis, as it may not allow for proper drainage and can increase the risk of respiratory compromise, especially in clients with large volumes of ascitic fluid.

C. High-Fowler’s position is correct because it helps pool the ascitic fluid in the lower abdomen, making it easier to access and drain during the procedure. This position also helps improve breathing by relieving pressure on the diaphragm caused by the ascites.

D. The leaning forward position is not appropriate for paracentesis, as it can be uncomfortable and does not provide optimal access to the abdominal cavity for fluid removal.

Correct Answer is B

Explanation

A. Radiofrequency catheter ablation is incorrect. This is a long-term treatment for arrhythmias but not for immediate management of VT.

B. Defibrillation is correct. Defibrillation is used for pulseless ventricular tachycardia or ventricular fibrillation to restore a normal heart rhythm.

C. CPR is incorrect. CPR is performed if the patient is unresponsive and pulseless, not as the first-line intervention for VT.

D. Elective cardioversion is incorrect. Elective cardioversion is used for stable arrhythmias such as atrial fibrillation, not for immediate VT treatment.
