Correct Answer: C

Rationale: In a patient with a history of angina experiencing chest pain, the priority action for the nurse is to obtain a 12-lead ECG. This helps in assessing for myocardial infarction, a serious condition that requires immediate attention. Administering oxygen, nitroglycerin, or notifying the healthcare provider can be important interventions but obtaining the ECG comes first to determine the presence of myocardial infarction and guide further management.

Correct Answer: A

Rationale: Methimazole is the correct answer. It is commonly used to treat hyperthyroidism by inhibiting the production of thyroid hormones. Levothyroxine, on the other hand, is a medication used to treat hypothyroidism by providing synthetic thyroid hormone. Propylthiouracil is another medication used to treat hyperthyroidism by blocking the production of thyroid hormones. Aspirin is not used to treat hyperthyroidism, but rather for pain relief and reducing inflammation.

Correct Answer: B

Rationale: The correct instruction the nurse should include is to advise the client to avoid consuming grapefruit juice when taking statin medication. Grapefruit juice can interfere with the metabolism of statins, leading to an increased risk of adverse effects. Taking the medication on an empty stomach (Choice A) or in the morning (Choice D) is not specifically necessary for statins. While increasing dietary fiber intake (Choice C) is generally beneficial for health, it is not a specific instruction related to taking statin medication.

Correct Answer: B

Rationale: The correct answer is B: Perform weight-bearing exercises. Weight-bearing exercises are essential for preventing further bone loss and improving bone density in clients with osteoporosis. Calcium supplements alone may not be sufficient to prevent bone loss without adequate physical activity. Option C, 'Avoid weight-bearing exercises,' is incorrect as these exercises are beneficial for bone health. Option D, 'Limit intake of high-phosphorus foods,' is not directly related to preventing further bone loss in osteoporosis.

Correct Answer: B

Rationale: The correct answer is B: Loss of interest in usual activities. Clients with PTSD often exhibit symptoms such as numbing, which can manifest as a loss of interest in activities they once enjoyed. Choice A, dependence on family and friends, is more indicative of seeking support rather than a direct symptom of PTSD. Choice C, ritualistic behavior, is more commonly associated with conditions like obsessive-compulsive disorder. Choice D, passive-aggressive behavior, is not a typical finding in clients with PTSD.
