A nurse is reinforcing teaching about a low-cholesterol diet with a client who had a myocardial infarction. Which of the following meal selections by the client indicates an understanding of the teaching?

The correct answer is A, C, D

Choice A reason: Allopurinol is a medication that helps reduce the production of uric acid, which is beneficial for patients with gout and urolithiasis to prevent the formation of uric acid stones.

Choice B reason: While regular exercise is generally beneficial for overall health, it does not have a direct impact on the prevention of uric acid stone formation. Therefore, it is not a specific recommendation for preventing uric acid stone.

Choice C reason: Foods high in purines can increase uric acid levels in the body, leading to the formation of uric acid stones. Limiting the intake of such foods is a key step in preventing uric acid stones.

Choice D reason: Adequate fluid intake is crucial as it helps to dilute the urine, which can prevent the formation of uric acid stones by reducing the concentration of uric acid in the urine.

Choice E reason: Contrary to the statement, lemonade may actually be beneficial in preventing uric acid stones because it contains citrate, which can help prevent stone formation. Citrate can bind to calcium and prevent stone formation, and it also makes the urine less acidic, which can help prevent the formation of uric acid stones.

Choice A reason: This is a correct statement, because checking the heart rate each day can help monitor the function and effectiveness of the pacemaker, and detect any signs of malfunction, such as bradycardia, tachycardia, or irregular rhythm.

Choice B reason: This is an incorrect statement, because the client still needs to take the antihypertensive medications as prescribed, even with a pacemaker. The pacemaker regulates the heart rate, but does not control the blood pressure, which can be affected by other factors, such as stress, diet, or kidney function.

Choice C reason: This is an incorrect statement, because the client should avoid stretching the arms above the head for the first few weeks after the pacemaker insertion, as it can cause dislodgment or damage to the pacemaker leads. The client should limit the arm movements and activities until the incision site heals and the provider approves.

Choice D reason: This is an incorrect statement, because the client can stand in front of a microwave oven without any risk, as long as the oven is in good working condition and does not leak radiation. The modern microwave ovens and pacemakers are designed to prevent any interference or damage. However, the client should avoid close contact with other sources of electromagnetic fields, such as metal detectors, cell phones, or MRI machines.
