The nurse needs to insert an indwelling urinary catheter into the preoperative client with renal insufficiency. Which is the best client teaching the nurse to provide about the purpose of the ca-theter?

3. Clients who have renal insufficiency are usually fluid overloaded and have elec-trolyte disorders because the kidney's ability to clear water and solute is impaired; precise measurement of I&O is important to avoid aggravating the client's fluid and electrolyte problems during surgery and helps to prevent the administration of exces-sive fluid or unsuitable electrolyte infusions that can be life threatening. If the client is oliguric, the catheter is removed quickly after surgery to decrease the risk of infec-tion.
1. An empty bladder helps prevent bladder infections by decreasing the risk of resi-dual urine and is an important consideration for clients with renal insufficiency; however, a bladder infection is not as an immediate threat to the client as fluid and electrolyte imbalance is.
2. A urinary catheter drains urine from an obstruction but clients with renal insuffi-ciency usually have renal damage from prerenal or intrarenal causes; an obstruction is a postrenal problem.
4. Incontinent urine interferes with wound healing; however, clients with renal insuf-ficiency are not necessarily incontinent.
