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 client with type 2 diabetes mellitus is taking 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 other predisposing factors. Monitoring for signs and symptoms of lactic acidosis, such as muscle pain, weakness, trouble breathing, dizziness, and slow or irregular heartbeat, is crucial when a client is taking metformin. Choice B, hypokalemia, is not a common side effect of metformin. Choice C, hyperglycemia, is contrary to the intended effect of metformin, which is to lower blood glucose levels. Choice D, weight gain, is not typically associated with metformin use; in fact, metformin may even contribute to weight loss in some individuals.

3. A client at risk for hypokalemia is being instructed by a nurse about foods high in potassium that should be included in the daily diet. The nurse determines that the client understands the food sources of potassium if the client states that the food item lowest in potassium is:

• A. Apples
• B. Carrots
• C. Spinach
• D. Avocado

Correct answer: A

Rationale: The correct answer is 'Apples.' Apples are the lowest in potassium among the given options. Carrots, spinach, and avocados are all higher in potassium content compared to apples. Carrots and spinach are vegetables known to have a moderate amount of potassium. Avocados, on the other hand, are a high-potassium fruit and would not be the lowest in potassium among the choices provided.

4. The nurse is caring for a client with primary adrenal insufficiency (Addison's disease). Which of the following laboratory findings would the nurse expect?

• A. Hypernatremia
• B. Hyperkalemia
• C. Hyperglycemia
• D. Hypercalcemia

Correct answer: B

Rationale: In primary adrenal insufficiency (Addison's disease), there is a decrease in aldosterone levels, leading to sodium loss and potassium retention. This imbalance results in hyperkalemia, making choice B the correct answer. Hypernatremia (choice A) is unlikely due to sodium loss. Hyperglycemia (choice C) and hypercalcemia (choice D) are not typically associated with primary adrenal insufficiency.

5. A healthcare professional caring for a client who has been receiving intravenous diuretics suspects that the client is experiencing a deficient fluid volume. Which assessment finding would the healthcare professional note in a client with this condition?

• A. Lung congestion
• B. Decreased hematocrit
• C. Increased blood pressure
• D. Decreased central venous pressure (CVP)

Correct answer: D

Rationale: Decreased central venous pressure (CVP) is the correct assessment finding in a client with deficient fluid volume. This is because a decrease in CVP indicates reduced blood volume returning to the heart, which is consistent with hypovolemia. Lung congestion (Choice A) would be more indicative of fluid volume excess, not deficiency. Decreased hematocrit (Choice B) may be seen in conditions such as anemia but is not specific to deficient fluid volume. Increased blood pressure (Choice C) is not typically associated with deficient fluid volume; in fact, hypovolemia often leads to decreased blood pressure.
