Answer :
The answer to the question is that a client weighing 165 lb. (75 kg) should have a urine output of 75 mL/hour to maintain an adequate fluid balance.
To provide an explanation, the standard urine output for a healthy adult is approximately 1 mL/kg/hour. In this case, the client weighs 75 kg, so the expected urine output per hour would be 75 mL. Since the question asks for urine output over 4 hours, the total expected urine output would be 300 mL (75 mL/hour x 4 hours). Therefore, an adequate fluid balance would be indicated if the client had a urine output of at least 300 mL over the 4-hour period.
