Correct Answer: A

Rationale: The correct answer is A: Avoid foods high in potassium. During an acute episode of gastritis, it is advisable to avoid foods high in potassium as they can exacerbate symptoms. Potassium-rich foods may irritate the stomach lining, leading to increased discomfort. Choices B, C, and D are incorrect. Avoiding foods high in sodium is not specifically related to managing gastritis. Increasing exercise to reduce stress is a good general recommendation but not directly related to managing gastritis symptoms. Drinking milk as a snack is not recommended for gastritis as dairy products can sometimes worsen symptoms due to their fat content.

Correct Answer: A

Rationale: The correct initial action for treating chest pain in acute coronary syndrome is to administer sublingual nitroglycerin. Nitroglycerin helps dilate blood vessels, reducing the workload on the heart and improving blood flow to the heart muscle. Administering aspirin can also be beneficial, but the priority is to address chest pain promptly. Checking cardiac enzymes and obtaining IV access are important steps but are not the initial actions needed to alleviate chest pain in acute coronary syndrome.

Correct Answer: A

Rationale: The correct answer is to avoid alcohol. In diabetes insipidus, excessive urination leads to fluid loss, so it is essential to avoid alcohol which can exacerbate dehydration. Choice B is incorrect as increasing exercise may not directly impact diabetes insipidus. Choice C is also incorrect because although increasing fluid intake may seem intuitive, it is not the primary concern in managing diabetes insipidus. Choice D is not directly related to managing diabetes insipidus; sodium restriction is more relevant in conditions like hypertension or heart failure.

Correct Answer: A

Rationale: Corrected Rationale: Muscle weakness is a common symptom of hypokalemia and should be closely monitored in affected patients. Hypokalemia is a condition characterized by low potassium levels in the blood, which can lead to muscle weakness, cramps, and even paralysis. While bradycardia (slow heart rate) can be associated with severe hypokalemia, monitoring for muscle weakness is more specific to the condition. Checking deep tendon reflexes is not typically a primary monitoring parameter for hypokalemia. Monitoring for hyperglycemia is not directly related to hypokalemia, as hypokalemia is primarily associated with potassium levels in the blood.

Correct Answer: A

Rationale: The correct answer is to avoid NSAIDs after cataract surgery to reduce the risk of bleeding. Choice B, wearing dark glasses when outdoors, is generally recommended after cataract surgery to protect the eyes from bright sunlight, but it is not the most critical instruction. Choice C, reporting green or yellow drainage immediately, is important to monitor for signs of infection, but it is not specific to cataract surgery. Choice D, itching is normal unless accompanied by pain and nausea, is not the most crucial advice post-cataract surgery. Therefore, the key instruction is to avoid NSAIDs to minimize bleeding risk.
