Correct Answer: A

Rationale: The correct instruction for the client is to take the regular insulin first, then the NPH insulin. Regular insulin should be administered before NPH insulin to prevent contamination and maintain the potency of each insulin type. Choice B is incorrect because NPH insulin should not be taken before regular insulin. Mixing the insulins in a separate syringe, as suggested in choice C, is not recommended as it may alter the effectiveness of the insulins. Choice D is also incorrect as taking the regular insulin first and immediately following it with NPH insulin is not the recommended administration sequence.

Correct Answer: C

Rationale: The correct answer is C. Glycosylated hemoglobin (HbA1c) reflects average blood glucose levels over the past 3 months. This test is used to assess long-term blood sugar control in individuals with diabetes. Choice A is incorrect because fasting is not required for an HbA1c test. Choice B is judgmental and not supported by the information provided. Choice D is not the most accurate statement to make based on the HbA1c result; adjusting insulin would depend on a more comprehensive assessment of the client's overall diabetes management.

Correct Answer: B

Rationale: The correct intervention for a client with SIADH is to restrict fluid intake. SIADH leads to water retention and dilution of sodium levels in the body, resulting in hyponatremia. Restricting fluid intake helps prevent further dilutional hyponatremia. Encouraging oral fluids (Choice A) would exacerbate the condition by further increasing fluid retention. Administering potassium supplements (Choice C) is not directly related to managing SIADH. Increasing sodium intake (Choice D) is contraindicated because it can worsen hyponatremia in clients with SIADH.

Correct Answer: C

Rationale: Propranolol is a beta-blocker that works by blocking the effects of adrenaline, which helps to reduce symptoms such as tachycardia (fast heart rate) and anxiety in individuals with hyperthyroidism. Choices A and B are incorrect because propranolol does not affect thyroid hormone production; it only addresses symptoms. Choice D is incorrect because propranolol does not prevent weight loss associated with hyperthyroidism.

Correct Answer: D

Rationale: Conveying empathy, trust, and respect can help reduce the client's anxiety and improve their overall experience during treatment. This approach creates a supportive environment and fosters a sense of safety and understanding for the client. Administering a sedative (Choice A) should not be the initial intervention for anxiety, as it does not address the underlying emotional needs of the client. Making sure the client knows all the correct medical terms (Choice B) may increase anxiety by overwhelming the client with technical information. Ignoring signs and symptoms of anxiety (Choice C) can lead to worsening distress and potential complications in the client's care.
