A nurse is teaching a client who has GERD about appropriate dietary choices. Which of the following food choices by the client indicates an understanding of the teaching?

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.

A. Strain the client's urine. This is incorrect because straining urine is necessary for clients with radioactive seeds placed in the bladder, but not for prostate cancer brachytherapy, where the seeds typically remain in place.
B. Limit each of the client's visitors to 2 hr per day. This is incorrect because visitors should be limited to short durations, but the exact time is typically restricted to 30 minutes per visit rather than a total of 2 hours per day.
C. Attach a dosimeter to the client's gown. This is incorrect because a dosimeter should be worn by healthcare staff, not attached to the client. It helps monitor radiation exposure for staff members.
D. Instruct visitors to stay 1 m (3.3 feet) away from the client. This is correct because maintaining a safe distance from the client helps minimize radiation exposure for visitors. Visitors should also limit their time near the client and avoid close contact.
