A patient with rheumatoid arthritis is prescribed methotrexate. What should the nurse include in the patient teaching?

Correct Answer: A

Rationale: The correct answer is A: Take folic acid supplements as prescribed. Methotrexate can lead to folic acid deficiency, so supplementing with folic acid helps prevent side effects. It is important for the nurse to educate the patient on the importance of taking folic acid to maintain overall health. Choice B is incorrect. While it is generally recommended to limit alcohol consumption with methotrexate, avoiding it completely may not be necessary for all patients. Choice C is incorrect. Methotrexate takes time to work, often several weeks to months, so immediate results should not be expected. Choice D is incorrect. Limiting fluid intake to 1 liter per day is not a standard recommendation for patients taking methotrexate. Adequate hydration is important for overall health.

Correct Answer: A

Rationale: The correct answer is A: Avoid foods high in vitamin K. Warfarin is a vitamin K antagonist, so consuming high-vitamin K foods can counteract its effects. By avoiding such foods, the medication can work effectively in preventing further blood clot formation. Choice B is incorrect because dairy products do not directly interact with warfarin. Choice C is incorrect as citrus fruits do not have a significant impact on warfarin therapy. Choice D is incorrect as sodium intake is not directly related to the action of warfarin.

Correct Answer: B

Rationale: The correct answer is B: Hyperkalemia. Spironolactone is a potassium-sparing diuretic commonly used in patients with heart failure. It works by blocking the aldosterone receptor, leading to potassium retention and potential hyperkalemia. Monitoring potassium levels is crucial as hyperkalemia can increase the risk of arrhythmias and other cardiac complications in heart failure patients. A: Hypokalemia is incorrect because spironolactone typically causes potassium retention. C: Hyponatremia and D: Hypernatremia are incorrect as spironolactone does not directly affect sodium levels. In summary, monitoring for hyperkalemia is essential in patients with heart failure taking spironolactone to prevent adverse cardiac events.

Correct Answer: A

Rationale: The correct answer is A: Report any vision changes immediately. This is crucial because hydroxychloroquine can cause retinal toxicity, which may lead to irreversible vision loss. Monitoring for vision changes allows for early detection and intervention. Choice B is incorrect as hydroxychloroquine is typically taken with food or milk to reduce gastrointestinal side effects. Choice C is irrelevant as there is no specific dietary restriction for hydroxychloroquine. Choice D is also incorrect as there is no evidence to support increasing green leafy vegetable intake in relation to hydroxychloroquine therapy.

Correct Answer: C

Rationale: The correct answer is C: Before meals. Omeprazole is a proton pump inhibitor that works by reducing stomach acid production. Taking it before meals allows the medication to be most effective in inhibiting the proton pumps before they are stimulated by food intake. This timing optimizes the drug's ability to reduce acid secretion during the digestion process. Choice A (With meals) is incorrect because taking omeprazole with meals may reduce its effectiveness as it will not have enough time to inhibit acid production before food intake. Choice B (At bedtime) is also incorrect as omeprazole works best when taken before meals to prevent acid production. Choice D (After meals) is incorrect because waiting until after meals to take omeprazole means that acid production has already been stimulated by the food consumed, reducing the drug's effectiveness in inhibiting acid secretion.
