Correct Answer is A

No explanation

A. Monitor for at least 150 mL of drainage every hour. B. Clamp the tube for 30 min every 8 hr. C. Pin the tubing to the client's bed sheets. D. Replace the unit when the drainage chamber is full.

Correct Answer is A

Explanation

Monitor for at least 150 mL of drainage every hour. The nurse should monitor the chest tube drainage for excessive or sudden increases in order to detect any complications, such as pneumothorax. Clamping the tube for 30 minutes every 8 hours is not standard practice and can cause complications. Pinning the tubing to the client's bed sheets can cause traction on the chest tube and should be avoided. The chest tube unit should only be replaced when there is a problem with the unit or the seals.

Choice B: Clamping the tube for 30 minutes every 8 hours is not standard practice and can cause complications.

Choice C: Pinning the tubing to the client's bed sheets can cause traction on the chest tube and should be avoided.

Choice D: The chest tube unit should only be replaced when there is a problem with the unit or the seals.
