Nursing Elites

1. A client with hyperthyroidism is prescribed propranolol. The nurse understands that this medication is used to:

• A. Increase metabolism
• B. Reduce anxiety
• C. Decrease heart rate
• D. Increase blood pressure

Correct answer: C

Rationale: Propranolol is a beta-blocker commonly used in the management of hyperthyroidism. It works by blocking the effects of adrenaline, resulting in a decrease in heart rate and blood pressure. Choice A is incorrect because propranolol does not increase metabolism; instead, it may have a mild inhibitory effect. Choice B is incorrect as propranolol is not primarily used to reduce anxiety, although it may have some anxiolytic effects. Choice D is incorrect as propranolol actually decreases blood pressure by blocking the effects of adrenaline on the heart and blood vessels.

2. How often should rotation sites for insulin injection be separated from one another?

• A. Every third day.
• B. Every week.
• C. Every 2-3 weeks.
• D. Every 2-4 weeks.

Correct answer: C

Rationale: Insulin injection sites should be rotated every 2-3 weeks to prevent lipodystrophy and ensure proper insulin absorption. Option A ('Every third day') is too frequent and does not allow enough time for the previous site to heal properly. Option B ('Every week') might not provide adequate time for the tissue to recover. Option D ('Every 2-4 weeks') could potentially lead to overuse of a single injection site, increasing the risk of lipodystrophy and inconsistent insulin absorption. Therefore, the recommended interval of every 2-3 weeks is optimal for insulin injection site rotation.

3. Nurse Perry is caring for a female client with type 1 diabetes mellitus who exhibits confusion, light-headedness, and aberrant behavior. The client is still conscious. The nurse should first administer:

• A. I.M. or subcutaneous glucagon.
• B. I.V. bolus of dextrose 50%.
• C. 15 to 20 g of a fast-acting carbohydrate such as orange juice.
• D. 10 U of fast-acting insulin.

Correct answer: C

Rationale: For a conscious client with hypoglycemia, the initial treatment should involve administering 15 to 20 g of a fast-acting carbohydrate, such as orange juice. This helps rapidly raise the client's blood glucose levels. Choices A and D are incorrect as administering glucagon or fast-acting insulin is not the first-line treatment for hypoglycemia in a conscious client. Choice B, an I.V. bolus of dextrose 50%, is a more invasive and aggressive intervention that is not typically indicated for a conscious client with hypoglycemia.

4. A male client with type 1 diabetes mellitus asks the nurse about taking an oral antidiabetic agent. Nurse Jack explains that these medications are only effective if the client:

• A. Prefers to take insulin orally.
• B. Has type 2 diabetes.
• C. Has type 1 diabetes.
• D. Is pregnant and has type 2 diabetes.

Correct answer: B

Rationale: Oral antidiabetic agents are specifically designed for type 2 diabetes mellitus. Type 1 diabetes requires insulin therapy as the primary treatment due to the absence of endogenous insulin production. Therefore, these medications are not effective for individuals with type 1 diabetes like the male client in this scenario. Choice A is incorrect as oral antidiabetic agents are not about preference but rather about treatment efficacy. Choice D is incorrect as being pregnant does not impact the effectiveness of oral antidiabetic agents; they are primarily indicated for type 2 diabetes.

5. A client with type 2 diabetes mellitus is prescribed metformin. The nurse should monitor the client for which of the following potential side effects?

• A. Lactic acidosis
• B. Hypokalemia
• C. Hyperglycemia
• D. Weight gain

Correct answer: A

Rationale: The correct answer is A, lactic acidosis. Metformin, a common medication for type 2 diabetes mellitus, can lead to lactic acidosis, particularly in individuals with renal impairment or predisposing factors. Monitoring for signs of lactic acidosis, such as muscle pain, weakness, trouble breathing, dizziness, and slow or uneven heart rate, is crucial to prevent serious complications. Choices B, C, and D are incorrect as metformin does not typically cause hypokalemia, hyperglycemia, or weight gain as its primary side effects.
