A nurse is preparing a client for a paracentesis. Which of the following actions should the nurse take?

Option A. Instruct the client to void, because this reduces the risk of bladder injury during the procedure. The other options are incorrect because they are not necessary or appropriate for a paracentesis. Option B, position the client on their left side, is incorrect because the client should be positioned upright or semi-Fowler's to allow gravity to assist with fluid drainage. Option C, insert an IV catheter, is incorrect because an IV catheter is not required for a paracentesis unless the client needs fluid replacement or medication administration. Option D, prepare the client for moderate (conscious) sedation, is incorrect because a paracentesis is usually performed under local anesthesia and does not require sedation.
