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 C
Explanation
Choice A reason: Offering a pair of non-skid socks is not the most important action to implement next. The client may already have non-skid socks on, or may not need them if they are not walking. The priority is to prevent falls and injuries when transferring the client to the chair.
Choice B reason: Placing the chair by the bed is a necessary action to implement, but not the next one. The chair should already be by the bed before the nurse raises the head of the bed and moves the client to a sitting position. The next action is to help the client stand up and move to the chair.
Choice C reason: Supporting the client when rising is the best action to implement next. The client may be weak, dizzy, or unsteady after a week of bedrest, and may need assistance to stand up and sit down. The nurse should use proper body mechanics and a transfer belt if needed to support the client.
Choice D reason: Determining how the client feels is a relevant action to implement, but not the next one. The nurse should assess the client's vital signs, comfort, and tolerance of the activity after transferring the client to the chair. The next action is to ensure the client's safety and stability.
Correct Answer is D
Explanation
Choice A reason: Urine specific gravity is a measure of the concentration of solutes in the urine. It is inversely related to the hydration status of the client. A high urine specific gravity indicates dehydration, while a low urine specific gravity indicates overhydration.
Choice B reason: Serum hematocrit is a measure of the percentage of red blood cells in the blood. It is also inversely related to the hydration status of the client. A high serum hematocrit indicates dehydration, while a low serum hematocrit indicates overhydration.
Choice C reason: Pulse rate is a measure of the frequency of the heartbeats. It is directly related to the hydration status of the client. A low pulse rate indicates dehydration, while a high pulse rate indicates overhydration.
Choice D reason: Urinary output is a measure of the amount of urine produced by the kidneys. It is directly related to the hydration status of the client. A low urinary output indicates dehydration, while a high urinary output indicates overhydration.
