Correct Answer: C

Rationale: When a client with rheumatoid arthritis is taking NSAIDs, the nurse should monitor serum creatinine levels. NSAIDs can potentially cause kidney damage, so monitoring creatinine levels helps assess for renal impairment. While monitoring hemoglobin, potassium, and white blood cell count may also be relevant in some cases, serum creatinine is the priority due to the risk of renal complications associated with NSAID use.

Correct Answer: B

Rationale: The correct answer is B: Administer the morphine sulfate as prescribed. In this situation, the client is experiencing symptoms of acute pulmonary edema, a complication of heart failure. Morphine is indicated as it helps reduce anxiety and respiratory distress by decreasing preload and afterload. It dilates blood vessels, reducing the workload of the heart and improving oxygenation. The priority is to administer the morphine promptly to alleviate the client's distress and improve oxygenation. Consulting the charge nurse (A) or reviewing the need for the morphine prescription with the provider (D) would cause a delay in providing essential treatment. Withholding the morphine (C) would not be appropriate as it is indicated for this condition.

Correct Answer: B

Rationale: Processed meats should be avoided by clients with hypertension as they are high in sodium, which can contribute to elevated blood pressure. It is essential to limit the intake of high-sodium foods to help manage hypertension. Bananas, low-fat yogurt, and whole grains are generally beneficial for heart health due to their nutrient content and should not be avoided in a heart-healthy diet.

Correct Answer: B

Rationale: The correct answer is B: Decreased fatigue and improved energy levels. Levothyroxine is a medication used to treat hypothyroidism by providing the body with the thyroid hormone it lacks. Therefore, a positive response to the medication would manifest as decreased fatigue and improved energy levels due to the correction of the thyroid hormone imbalance. Choices A, C, and D are incorrect because improved tolerance to cold, reduced anxiety, and increased sensitivity to heat are not direct indicators of the effectiveness of levothyroxine in managing hypothyroidism.

Correct Answer: B

Rationale: A significant drop in blood pressure following anesthesia could indicate a serious reaction, such as hypovolemia or anesthetic-induced hypotension. This requires immediate medical attention, while other symptoms like dizziness, mild nausea, and dry mouth are more common and less critical. Dizziness could be expected due to the effects of anesthesia, mild nausea is a common side effect, and dry mouth is a known effect of anesthesia as well.
