A nurse is caring for a client who is postoperative following the placement of a colostomy. Which of the following findings indicates that the colostomy is functioning properly?

The correct answer is A:

Choice A reason:

Replace the unit when the drainage chamber is full. This ensures continuous, effective drainage. A full chamber cannot collect more fluid, risking system compromise and patient safety.

Choice B reason:

Pinning the tubing to the bed sheets is incorrect because it can cause kinks in the tubing, leading to obstruction of drainage and potential complications.

Choice C reason:

Monitoring for at least 150 mL of drainage every hour is not a standard practice. Normal chest tube drainage is variable; excessive drainage, such as 150 mL/hour, could indicate a serious condition like hemorrhage.

Choice D reason:

Clamping the tube routinely for 30 minutes every 8 hours is not recommended. Clamping may be done during tube removal or to check for air leaks but doing so routinely can lead to tension pneumothorax.

Choice A: This is incorrect because Sims position is used for clients who have lower back pain, abdominal surgery, or enemas. It is not appropriate for clients who have a closed head injury.

Choice B: This is incorrect because modified Trendelenburg position is used for clients who have hypovolemic shock or poor venous return. It is not appropriate for clients who have a closed head injury.

Choice C: This is correct because semi-Fowler's position is used for clients who have increased intracranial pressure, respiratory distress, or head trauma. It elevates the head and chest to reduce cerebral edema and facilitate breathing.

Choice D: This is incorrect because prone position is used for clients who have acute respiratory distress syndrome, spinal cord injury, or pressure ulcers. It is not appropriate for clients who have a closed head injury.
