Correct Answer: B

Rationale: The correct answer is to place the nitroglycerin tablet under the tongue. Nitroglycerin tablets are meant for sublingual absorption during angina episodes to provide quick relief. Option A is incorrect because nitroglycerin should not be taken with food. Option C is incorrect as nitroglycerin should be stored in a cool, dark place, not in the refrigerator. Option D is incorrect because nitroglycerin can have side effects, including headaches, dizziness, and low blood pressure.

Correct Answer: A

Rationale: In this scenario, the nurse should respond by indicating that the patient needs to provide permission to share their medical records with the family member. Patient confidentiality is a fundamental principle in healthcare, and sharing medical records without the patient's consent is a violation of privacy. Choice B is incorrect because the provider's approval alone is not sufficient to share medical records, as patient consent is crucial. Choice C is incorrect because viewing the patient's chart without the patient's consent is not appropriate. Choice D is incorrect as filling out a request form does not address the issue of patient consent, which is essential for sharing medical information.

Correct Answer: A

Rationale: The correct answer is A: Hyperkalemia. Clients with chronic kidney disease are at risk for hyperkalemia due to impaired potassium excretion. In chronic kidney disease, the kidneys are unable to effectively excrete potassium, leading to its accumulation in the blood. Hypercalcemia (Choice B) is not typically associated with chronic kidney disease. Hypoglycemia (Choice C) refers to low blood sugar levels and is not directly related to chronic kidney disease. Hyponatremia (Choice D) is a condition characterized by low sodium levels and is not a typical concern in chronic kidney disease.

Correct Answer: A

Rationale: The correct instruction for a client prescribed ferrous sulfate for anemia is to take the medication on an empty stomach. This is because ferrous sulfate is best absorbed in an acidic environment, which is enhanced on an empty stomach. However, if the client experiences gastrointestinal side effects, they can take the medication with food. Choice B, notifying the provider if stool becomes dark green, is correct because dark or black stools are common with iron therapy and not a cause for concern. Choice C, decreasing dietary fiber intake, is incorrect as dietary fiber does not interfere with the absorption of ferrous sulfate. Choice D, taking prescribed antacids at the same time, is incorrect as antacids can decrease the absorption of ferrous sulfate.

Correct Answer: A

Rationale: The correct answer is A: Gastrointestinal upset. Metformin can cause gastrointestinal upset, especially when first starting therapy. It is important to take it with food to reduce these effects. Increased appetite (choice B) and weight loss (choice C) are not common side effects of metformin but may occur due to improved blood sugar control. Frequent urination (choice D) is a symptom of uncontrolled diabetes and not a side effect of metformin.
