A nurse is caring for a client who has a three-chamber chest tube system. Which of the following actions should the nurse take?
Ensure 2 cm (0.8 in) of water is in the water seal chamber.
Check the patency of the tubing every 2 hr.
Keep the drainage system above the level of the client's chest.
Empty the collection chamber every 8 hr.
The Correct Answer is A
A. Ensure 2 cm (0.8 in) of water is in the water seal chamber. This is correct because maintaining the correct water level in the water seal chamber is essential for proper functioning of the chest tube system, as it prevents air from entering the pleural space.
B. Check the patency of the tubing every 2 hr. This is incorrect because continuous monitoring is required, and patency should be ensured at all times, not just at set intervals. However, frequent assessments are important.
C. Keep the drainage system above the level of the client's chest. This is incorrect because the drainage system should be kept below chest level to allow gravity drainage and prevent backflow into the pleural space.
D. Empty the collection chamber every 8 hr. This is incorrect because the collection chamber should only be emptied when full, following facility protocol, to maintain an accurate record of drainage output.

Correct Answer is B
Explanation
A. Choose the client's dominant arm for IV access whenever possible. The nondominant arm is preferred to minimize interference with daily activities.
B. Select a site proximal to previous venipuncture sites. This is the appropriate action because using a site above a previous one ensures better vein integrity and reduces complications.
C. Initiate IV access on the palmar side of the client's wrist. This site should be avoided as it is more painful and increases the risk of nerve damage.
D. Insert a larger gauge IV catheter to prevent phlebitis. A smaller gauge catheter is preferred when possible, as larger catheters can increase the risk of vein irritation and phlebitis.
Correct Answer is D
Explanation
A. Sore throat. This is incorrect because a sore throat is an expected postoperative finding following a tonsillectomy and does not indicate a complication.
B. Dark brown emesis. This is incorrect because dark brown emesis may be swallowed blood from surgery and is not necessarily an immediate concern unless it continues or turns bright red.
C. Blood-tinged mucus. This is incorrect because small amounts of blood-tinged mucus are normal after a tonsillectomy and do not indicate active bleeding.
D. Frequent swallowing. This is correct because frequent swallowing can indicate active bleeding from the surgical site. Post-tonsillectomy hemorrhage is a serious complication that requires immediate intervention.
