A nurse is admitting a client who is to undergo paracentesis for removal of ascitic fluid. Which of the following actions should the nurse take?

A. Place the client in a side-lying position for the procedure: Paracentesis is typically performed with the client in an upright or high-Fowler’s position to allow fluid to pool in the lower abdomen for easier access and drainage. B. Administer a low-volume hypertonic enema the night before the procedure: Enemas are not routinely indicated for paracentesis since the bowel does not obstruct access to ascitic fluid, making this an unnecessary step. C. Ensure the client has a full bladder just prior to the procedure: A full bladder increases the risk of accidental puncture during needle insertion. The bladder should be emptied to reduce this risk. D. Weigh the client before and after the procedure: Weighing the client allows the healthcare team to estimate the volume of ascitic fluid removed and assess fluid balance, making this a key nursing responsibility.
