A nurse is reinforcing teaching about healthy lifestyle changes with a female client who has mild hypertension. Which of the following statements by the client indicates an understanding of the teaching?

C, "You can begin collection of urine after discarding your first morning void."

A 24-hour creatinine clearance test is used to evaluate how well the kidneys are functioning by measuring the amount of creatinine in the blood and urine over a 24-hour period. During the test, the client is asked to discard their first morning void and then collect all urine for the next 24 hours.

Option A is incorrect because a protein-rich diet can affect the creatinine levels in the urine, which can result in inaccurate test results. Therefore, the nurse should advise the client to avoid a protein-rich diet during the collection period.

Option B is incorrect because blood glucose levels are not relevant to a 24-hour creatinine clearance test. Therefore, the nurse should not ask the client to record their blood glucose level each time they void.

Option D is incorrect because using an antiseptic towel to cleanse the perineal area can also affect the test results by introducing contaminants into the urine sample. Therefore, the nurse should advise the client to cleanse the perineal area with soap and water or an alcohol wipe.

Albuterol is a bronchodilator medication that is commonly delivered through a metered-dose inhaler (MDI) to treat asthma and other respiratory conditions. Proper inhaler technique is crucial for the effective delivery of the medication to the lungs.

Option (a) is incorrect because the client should actually tilt their head back slightly and breathe out fully before inhaling the medication.

Option (b) is incorrect because the client should take a slow, deep breath while depressing the canister once.

Option (d) is incorrect because the client should hold their breath for 10 seconds after inhaling the medication to allow it to reach the lungs.

Therefore, the correct instruction for the nurse to include in the teaching is to instruct the client to close their mouth around the mouthpiece of the inhaler to ensure that the medication is delivered directly to the lungs.
