A nurse is caring for a client who is scheduled to have his alanine aminotransferase (ALT) level checked. The client asks the nurse to explain the laboratory test. Which of the following is an appropriate response by the nurse?

Choice A Reason:
Perform percussion over the lower back. Percussion is typically performed over the lung segments being drained, and it is commonly done with cupped hands to promote loosening and mobilization of mucus in the airways. In the case of cystic fibrosis, this procedure is typically done on the back to help clear mucus from the lungs.
Choice B Reason:
Cover the area of percussion with a towel. Placing a towel or cloth over the area of percussion helps to protect the skin and provide some comfort for the client during the procedure.

Choice CReason:
Schedule postural drainage after meals. Postural drainage is typically scheduled at times when the client is less likely to have a full stomach, as it can be uncomfortable and lead to nausea if performed immediately after meals. It's important to provide the client with time to digest before the procedure.

Choice DReason:
Instruct the client to exhale quickly during vibration. Vibration is often performed by having the client exhale quickly while the nurse applies gentle oscillations to the chest wall. This helps dislodge mucus and facilitate its removal.

Choice A Reason:
A Emptying the drainage bag when it is three-quarters full is not necessary for routine care. Emptying the bag when it's approximately half full is a more common practice to prevent overdistension of the bag and to maintain an accurate measurement of urine output.
Choice B Reason:
Taping the catheter to the lower abdomen is not recommended, as it can lead to complications such as catheter-associated urinary tract infections. The catheter should be secured to the client's thigh or the bedding, but not to the abdomen.
Choice C Reason:
Keep the drainage bag below the level of the bladder. Maintaining the drainage bag below the level of the bladder is essential to ensure proper urine flow and prevent backflow into the bladder, reducing the risk of infection. This action helps maintain the integrity of the closed urinary drainage system.
Choice D Reason:
Attaching the drainage bag to the side rails of the bed is not recommended as it can lead to contamination and potential complications. It's best to keep the drainage bag on a designated hanger or hook that is not in direct contact with the bed or floor.
