The healthcare provider prescribes a 24-hour urine specimen to be collected for creatinine clearance. The client is eager to go home and tells the nurse that the first sample was put in the urinal 2 hours ago. Which action should the nurse implement?
Start collecting the specimen with the next void.
Begin the collection the next day.
Observe the sample for sediment.
Empty the sample into the 24-hour container.
The Correct Answer is A
The correct answer is A. Start collecting the specimen with the next void.
Choice A reason: The 4-hour urine collection for creatinine clearance should start with an empty bladder. The first urine of the day is discarded and the time is noted. All subsequent urine for the next 4 hours, including the first urine the following day, should be collected. If the first sample was put in the urinal hours ago and was not collected, the nurse should start collecting the specimen with the next void.
Choice B reason: Beginning the collection the next day would delay the test and may not be necessary. The test should ideally start after the first urine of the day is discarded.
Choice C reason: Observing the sample for sediment is not typically part of the procedure for a 4-hour urine collection for creatinine clearance. The focus is on collecting all urine for a specified period, not on the physical characteristics of the sample.
Choice D reason: Emptying the sample into the 4-hour container would be incorrect if the sample was the first urine of the day, which should be discarded. The collection should start with the next void.

Correct Answer is A
Explanation
Choice A reason: This is the most therapeutic response as it invites the client to share her feelings and thoughts about the visit. It also shows the nurse's interest and empathy for the client.
Choice B reason: This is a less therapeutic response as it is vague and non-specific. It does not address the client's behavior or mood. It also puts the burden on the client to initiate the conversation.
Choice C reason: This is a less therapeutic response as it assumes that the client enjoyed the visit. It may not reflect the client's true feelings or experiences. It also limits the client's expression to positive aspects only.
Choice D reason: This is a non-therapeutic response as it labels the client's emotion without validation. It may not accurately describe the client's feeling or situation. It also closes the communication by making a statement instead of asking a question.
Correct Answer is A
Explanation
Choice A reason: Providing oral sponge toothettes is the best action to take. It helps the client to maintain oral hygiene and comfort, and prevents dryness and cracking of the oral mucosa.
Choice B reason: Teaching the client that the oral mucosa must remain dry to prevent aspiration is not a correct action. The oral mucosa needs to be moist to protect it from infection and irritation. Aspiration is prevented by checking the placement of the nasogastric tube and keeping the head of the bed elevated.
Choice C reason: Turning the suction off while allowing the client to rinse his mouth with cool water is not a safe action. It may increase the risk of aspiration and interfere with the function of the nasogastric tube. The suction should only be turned off when necessary, such as during medication administration or tube feeding.
Choice D reason: Instilling 50 ml of normal saline solution into the tube and clamping the tube for one hour is not an appropriate action. It may cause fluid overload, electrolyte imbalance, and abdominal distension. The nasogastric tube should be flushed with 30 ml of water every 4 to 6 hours to maintain patency and prevent clogging.
