A client with obstructive sleep apnea (OSA) calls the clinic to report difficulty wearing the continuous positive air pressure (CPAP) mask because it is uncomfortable. The client asks the nurse for an alternative way to manage sleep apnea. Which recommendation should the nurse provide?

Choice A reason: Sweet potatoes are not a food that the client should avoid after passing a calcium oxalate renal stone, because they are low in oxalate, which is a substance that can combine with calcium in the urine and form stones. The client should limit foods that are high in oxalate, such as spinach, rhubarb, beets, nuts, chocolate, tea, and wheat bran. Therefore, this choice is incorrect.

Choice B reason: Spinach salad is a food that the client should avoid after passing a calcium oxalate renal stone, because it is high in oxalate, which can increase the risk of stone formation. The client should consume foods that are low in oxalate, such as rice, corn, apples, grapes, peaches, and cheese. Therefore, this choice is correct.

Choice C reason: Bananas are not a food that the client should avoid after passing a calcium oxalate renal stone, because they are low in oxalate and high in potassium, which can help prevent stone formation. The client should increase the intake of fluids, calcium, and citrate, which can reduce the concentration of oxalate and calcium in the urine and inhibit stone formation. Therefore, this choice is incorrect.

Choice D reason: Fish is not a food that the client should avoid after passing a calcium oxalate renal stone, because it is low in oxalate and high in protein, which can help maintain muscle mass and prevent weight loss. The client should moderate the intake of animal protein, such as meat, poultry, eggs, and dairy products, which can increase the acidity of the urine and promote stone formation. Therefore, this choice is incorrect.

Choice A reason: Using incentive spirometer is not an information that the nurse should include in the discharge instructions for a client with BPH following a TUNA, because it is not related to the procedure or the condition. The incentive spirometer is a device that helps improve lung function and prevent respiratory complications by encouraging deep breathing and coughing. Therefore, this choice is incorrect.

Choice B reason: Monitoring urinary stream for decrease in output is an information that the nurse should include in the discharge instructions for a client with BPH following a TUNA, because it can indicate urinary retention or obstruction, which are potential complications of the procedure. The client should report any difficulty or inability to urinate, severe pain, or fever to the health care provider. Therefore, this choice is correct.

Choice C reason: Reporting when hematuria becomes pink tinged is not an information that the nurse should include in the discharge instructions for a client with BPH following a TUNA, because it is not a sign of a problem. Hematuria, or blood in the urine, is a common and expected finding after the procedure, and it usually resolves within a few days. The client should drink plenty of fluids to flush out the blood clots and debris. Therefore, this choice is incorrect.

Choice D reason: Restricting physical activities is an information that the nurse should include in the discharge instructions for a client with BPH following a TUNA, but it is not the best answer. The client should avoid strenuous activities, such as lifting heavy objects, driving, or sexual intercourse, for at least two weeks after the procedure to prevent bleeding and infection. However, this information is less important than monitoring urinary stream for decrease in output. Therefore, this choice is not the best answer.
