Nursing Elites

1. A client with hyperthyroidism is prescribed methimazole. The nurse should instruct the client that the purpose of this medication is to:

• A. Decrease thyroid hormone production
• B. Increase thyroid hormone production
• C. Suppress the immune system
• D. Prevent thyroid storm

Correct answer: A

Rationale: The correct answer is A: Decrease thyroid hormone production. Methimazole works by inhibiting the synthesis of thyroid hormones, specifically by blocking the enzyme responsible for this process. By reducing the production of thyroid hormones, methimazole helps to normalize the elevated levels seen in hyperthyroidism. Choices B, C, and D are incorrect. Choice B, 'Increase thyroid hormone production,' is inaccurate as methimazole actually decreases thyroid hormone production. Choice C, 'Suppress the immune system,' is unrelated to the mechanism of action of methimazole. Choice D, 'Prevent thyroid storm,' is not the primary purpose of methimazole; while it may help prevent worsening of hyperthyroidism, its main action is to reduce thyroid hormone levels.

2. Nurse Wayne is aware that a positive Chvostek's sign indicates:

• A. Hypocalcemia
• B. Hyponatremia
• C. Hypokalemia
• D. Hypermagnesemia

Correct answer: A

Rationale: A positive Chvostek's sign indicates hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching due to increased neuromuscular irritability from low calcium levels. Hyponatremia (Choice B) is characterized by low sodium levels, but it does not present with Chvostek's sign. Hypokalemia (Choice C) is low potassium levels, and hypermagnesemia (Choice D) is high magnesium levels, neither of which are associated with Chvostek's sign.

3. During a physical assessment of a client with type 2 DM, a nurse notes the following findings: fasting blood glucose of 120 mg/dl, temperature of 101°F, pulse 88 bpm, respirations 22/min, and BP 140/84 mmHg. Which finding should concern the nurse the most?

• A. Pulse
• B. BP
• C. Respiration
• D. Temperature

Correct answer: D

Rationale: The correct answer is 'Temperature.' A temperature of 101°F indicates a fever, which can be a sign of infection. In individuals with diabetes, infections can lead to significant complications and affect blood glucose control. Monitoring and addressing infections promptly are crucial in individuals with diabetes to prevent worsening of their condition. Choice A, 'Pulse,' is within the normal range (60-100 bpm) and does not indicate an immediate concern. Choice B, 'BP,' while slightly elevated, is not as acutely concerning as an elevated temperature in this scenario. Choice C, 'Respiration,' falls within the normal range (12-20 breaths/min) and is not the most concerning finding among the options provided.

4. A client with DM is taking regular and NPH insulin every morning. The nurse should provide which instruction to the client?

• A. Take the regular insulin first, then the NPH insulin.
• B. Take the NPH insulin first, then the regular insulin.
• C. Mix the insulins in a separate syringe.
• D. Take the regular insulin first and immediately follow it with the NPH insulin.

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.

5. A nurse is preparing a plan of care for a client with DM who has hyperglycemia. The priority nursing diagnosis would be:

• A. High risk for deficient fluid volume
• B. Deficient knowledge: disease process and treatment
• C. Imbalanced nutrition: less than body requirements
• D. Disabled family coping: compromised

Correct answer: A

Rationale: The priority nursing diagnosis for a client with diabetes mellitus (DM) experiencing hyperglycemia would be 'High risk for deficient fluid volume.' Hyperglycemia can lead to osmotic diuresis, causing significant fluid loss and an increased risk of deficient fluid volume. This nursing diagnosis addresses the immediate physiological concern related to fluid balance.\n\nChoice B, 'Deficient knowledge: disease process and treatment,' focuses on the client's understanding of DM, which is important but not the priority when the client is at risk of fluid volume deficit.\n\nChoice C, 'Imbalanced nutrition: less than body requirements,' pertains to inadequate intake of nutrients, which is not the priority concern when fluid volume deficit poses a more immediate threat.\n\nChoice D, 'Disabled family coping: compromised,' addresses a psychosocial aspect and is not the priority over the critical physiological issue of fluid volume deficit in a client with hyperglycemia.
