Rationale: To ensure accurate creatinine clearance results, it is crucial to collect all urine within the 24-hour period. The process should begin with discarding the first specimen and then collecting all subsequent urine in the designated 24-hour collection container. This ensures that the sample is complete and accurate for the creatinine clearance calculation.

Correct Answer: B

Rationale: Theophylline should be administered on a regular around-the-clock schedule to provide the best bronchodilating effect and reduce the potential for adverse effects. The correct dosing schedule of 8 a.m., 4 p.m., and midnight ensures that the client receives consistent dosing throughout the day. Other options do not provide the necessary around-the-clock coverage. It's important to note that food may affect the absorption of the medication, which is why the dosing schedule should not be tied to meal times.

Correct Answer: A

Rationale: Monitoring urine output is the most direct way to assess kidney function as it provides crucial information about the kidneys' ability to filter waste and produce urine. Changes in urine output can indicate potential issues with kidney function, such as decreased filtration or impaired excretion of waste products.

Correct Answer: B

Rationale: For a client with redness in the sacral area, the most critical instruction is to change positions in the chair at least every hour. This is crucial to prevent pressure ulcers, which can develop due to prolonged pressure on the skin and underlying tissues. Regular position changes help relieve pressure on vulnerable areas, promoting circulation and reducing the risk of skin breakdown and pressure ulcer formation.

Correct Answer: A

Rationale: To demonstrate active listening effectively, it is essential to display open and engaging body language. Sitting facing the individual helps convey attentiveness and a willingness to listen. Maintaining eye contact further enhances the connection and shows respect and interest in the conversation. Crossing arms and legs can create a barrier and signal defensiveness or disinterest. Avoiding eye contact may suggest a lack of engagement or attentiveness. Leaning back in the chair can indicate relaxation but might be perceived as disengagement. Therefore, the most appropriate nonverbal action to demonstrate active listening is to sit facing the individual and maintain eye contact.
