Nursing Elites

1. A client with diabetes mellitus is scheduled for surgery. The nurse should prioritize which of the following preoperative actions?

• A. Administer a full dose of insulin before surgery
• B. Hold all oral hypoglycemic agents the day before surgery
• C. Monitor blood glucose levels closely before surgery
• D. Instruct the client to avoid all fluids the morning of surgery

Correct answer: C

Rationale: Monitoring blood glucose levels closely before surgery is the priority for a client with diabetes mellitus. This allows for early detection of any abnormalities and helps prevent hypo- or hyperglycemia complications that can arise during the perioperative period. Option A is incorrect because insulin dosing should be individualized based on the client's current blood glucose levels and the surgical plan. Option B is incorrect as abruptly holding oral hypoglycemic agents can lead to uncontrolled blood glucose levels. Option D is incorrect as adequate fluid intake is important for the client's hydration status and overall well-being before surgery.

2. A nurse is preparing to administer NPH insulin to a client with DM. The nurse notes that the NPH insulin vial is cloudy. The nurse should:

• A. Obtain a new vial of NPH insulin.
• B. Draw up the cloudy insulin as ordered.
• C. Shake the vial vigorously before drawing up the insulin.
• D. Warm the insulin to room temperature before administration.

Correct answer: B

Rationale: The correct answer is to draw up the cloudy insulin as ordered. NPH insulin is inherently cloudy due to its suspension of insulin crystals. Shaking the vial vigorously can lead to denaturation of the insulin molecules, altering its efficacy. Warming NPH insulin is not necessary as it can cause breakdown of insulin molecules. The nurse should gently roll the vial between hands to mix it before drawing it up to ensure an even distribution of insulin in the suspension.

3. The nurse is caring for a client with diabetes insipidus. Which of the following laboratory findings should the nurse monitor?

• A. Serum sodium
• B. Serum potassium
• C. Serum calcium
• D. Serum magnesium

Correct answer: A

Rationale: In diabetes insipidus, there is excessive excretion of water leading to dehydration. Monitoring serum sodium levels is crucial because these clients often experience hypernatremia (elevated serum sodium levels) due to the loss of relatively more water than sodium, resulting in a sodium concentration imbalance. While monitoring serum potassium, calcium, and magnesium levels is also important in various conditions, they are not the primary focus in diabetes insipidus.

4. What is the most common cause of hyperaldosteronism?

• A. Excessive sodium intake
• B. A pituitary adenoma
• C. Deficient potassium intake
• D. An adrenal adenoma

Correct answer: D

Rationale: An adrenal adenoma is the most common cause of primary hyperaldosteronism. Hyperaldosteronism is typically caused by an adrenal adenoma, a benign tumor in the adrenal gland that leads to excessive aldosterone production. Excessive sodium intake (Choice A) does not directly cause hyperaldosteronism. Pituitary adenoma (Choice B) is associated with conditions like Cushing's disease, not hyperaldosteronism. Deficient potassium intake (Choice C) can lead to hypokalemia but is not a common cause of hyperaldosteronism.

5. A client with type 2 DM is being taught about the importance of foot care. Which instruction should the nurse include?

• A. Wear comfortable shoes that allow air circulation.
• B. Walk barefoot whenever possible.
• C. Use a heating pad to warm your feet.
• D. Soak your feet in hot water every night.

Correct answer: A

Rationale: The correct instruction for a client with type 2 diabetes mellitus (DM) regarding foot care is to wear comfortable shoes that allow air circulation. This recommendation helps prevent foot injuries and infections, which are common concerns for individuals with diabetes. Choice B, walking barefoot, can increase the risk of injuries and wounds due to reduced sensation in the feet often seen in diabetes. Choice C, using a heating pad, can lead to burns or skin damage if the temperature is not carefully monitored, making it an unsafe practice. Choice D, soaking feet in hot water every night, can also be harmful as it can cause burns and dry out the skin, leading to further complications for individuals with diabetes. Therefore, the most appropriate and safe advice is to wear comfortable shoes that promote air circulation to maintain foot health and prevent complications.
