Nursing Elites

1. A nurse assesses a client who is prescribed furosemide (Lasix) for hypertension. For which acid-base imbalance should the nurse assess to prevent complications of this therapy?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: D

Rationale:

2. What is the main force that pushes fluid in blood capillaries?

• A. Blood pressure.
• B. Sodium in the blood plasma.
• C. Sodium in the interstitial fluid.
• D. Protein in the blood plasma.

Correct answer: A

Rationale: The correct answer is A, blood pressure. Blood pressure is the primary force that pushes fluid out of the capillaries into the surrounding tissues. This pressure difference is essential for the exchange of nutrients, gases, and waste products between the blood and tissues. Choices B, C, and D are incorrect as they do not represent the primary force responsible for pushing fluid in blood capillaries.

3. Your patient has alcoholism, and you may suspect during your assessment that his serum magnesium is low. What will the nurse potentially expect to assess related to hypomagnesemia?

• A. Tremor
• B. Pruritus
• C. Edema
• D. Decreased blood pressure

Correct answer: A

Rationale: The correct answer is A: Tremor. Signs and symptoms of hypomagnesemia primarily affect the neuromuscular system and can include tremors, confusion, tetany, laryngeal stridor, and ataxia. Pruritus (choice B) refers to itching and is not typically associated with hypomagnesemia. Edema (choice C) is swelling caused by fluid retention and is not a common manifestation of hypomagnesemia. Decreased blood pressure (choice D) is not a typical sign of hypomagnesemia; instead, low magnesium levels are more likely to cause hypertension.

4. You are working on a burns unit, and one of your acutely ill patients is exhibiting signs and symptoms of third spacing. Based on this change in status, you should expect the patient to exhibit signs and symptoms of what imbalance?

• A. Metabolic alkalosis
• B. Hypermagnesemia
• C. Hypercalcemia
• D. Hypovolemia

Correct answer: D

Rationale: When a patient exhibits signs and symptoms of third-spacing, where fluid moves out of the intravascular space but not into the intracellular space, hypovolemia is expected. This leads to a decreased circulating blood volume. Increased calcium and magnesium levels are not typically associated with third-spacing fluid shift. Burns usually result in acidosis rather than alkalosis, making metabolic alkalosis an incorrect choice. Therefore, hypovolemia is the correct answer in this scenario.

5. A nurse is assessing clients on a medical-surgical unit. Which clients are at increased risk for hypophosphatemia? (Select all that do not apply.)

• A. A 36-year-old who is malnourished
• B. A 42-year-old with uncontrolled diabetes
• C. A 76-year-old who is prescribed antacids
• D. 50-year-old with hyperparathyroidism

Correct answer: C
