Nursing Elites

1. The nurse is reviewing the laboratory results of a client with chronic kidney disease. The client's serum calcium level is 7.5 mg/dL. Which condition should the nurse suspect?

• A. Hypercalcemia
• B. Hyperkalemia
• C. Hyponatremia
• D. Hypocalcemia

Correct answer: D

Rationale: A serum calcium level of 7.5 mg/dL is indicative of hypocalcemia, a common complication in clients with chronic kidney disease due to impaired calcium absorption and metabolism. Hypercalcemia (Choice A) is the opposite of the condition presented in the question and is characterized by elevated serum calcium levels. Hyperkalemia (Choice B) is an increased potassium level, not related to the client's serum calcium level. Hyponatremia (Choice C) is a decreased sodium level and is also not related to the client's serum calcium level.

2. A client with cirrhosis is prescribed spironolactone to manage ascites. Which serum laboratory value is most important for the nurse to monitor?

• A. Sodium
• B. Calcium
• C. Magnesium
• D. Potassium

Correct answer: D

Rationale: The correct answer is D: Potassium. Spironolactone is a potassium-sparing diuretic, which can lead to hyperkalemia. Monitoring potassium levels is crucial to prevent complications like cardiac arrhythmias. Choices A, B, and C are incorrect because sodium, calcium, and magnesium levels are not directly affected by spironolactone use for managing ascites in cirrhosis.

3. The nurse is providing care for a client with a percutaneous endoscopic gastrostomy (PEG) tube. Which intervention should the nurse implement to prevent complications associated with the tube?

• A. Elevate the head of the bed to 15 degrees during feedings
• B. Aspirate gastric contents before administering medications
• C. Clamp the tube between feedings
• D. Flush the tube with water before and after feedings

Correct answer: D

Rationale: Flushing the PEG tube with water before and after feedings helps prevent clogging and maintains tube patency. Proper flushing is essential for avoiding complications related to tube blockages. Elevating the head of the bed is important for preventing aspiration during and after feedings, not specifically related to PEG tube complications. Aspirating gastric contents before administering medications is not routinely recommended for PEG tube care. Clamping the tube between feedings can lead to tube occlusion and is not a standard practice in PEG tube care.

4. A client is admitted with diabetic ketoacidosis (DKA). Which laboratory result would the nurse expect to find in this client?

• A. pH level of 7.45
• B. Serum calcium of 15 mg/dL
• C. Blood glucose of 450 mg/dL
• D. Sodium level of 120 mEq/L

Correct answer: C

Rationale: Clients with diabetic ketoacidosis typically present with elevated blood glucose levels, often above 300 mg/dL. This high blood glucose level, along with other symptoms, helps confirm the diagnosis of DKA. A pH level of 7.45 would be indicative of alkalosis, not the acidosis seen in DKA. A serum calcium level of 15 mg/dL is significantly elevated and is not a typical finding in DKA. A sodium level of 120 mEq/L indicates hyponatremia, which is not a characteristic laboratory finding in DKA.

5. After a thyroidectomy, which vital sign is the most important for the nurse to monitor closely?

• A. Monitor respiratory rate and rhythm.
• B. Assess for signs of hypocalcemia.
• C. Monitor for elevated body temperature.
• D. Check blood pressure every 30 minutes.

Correct answer: B

Rationale: The correct answer is B: Assess for signs of hypocalcemia. After a thyroidectomy, monitoring for hypocalcemia is crucial because damage to the parathyroid glands during surgery can result in low calcium levels, which may cause life-threatening complications. Monitoring respiratory rate and rhythm (choice A) is important but not the most critical in this situation. Monitoring for elevated body temperature (choice C) is less of a priority post-thyroidectomy. Checking blood pressure every 30 minutes (choice D) is not as vital as monitoring for hypocalcemia in this context.
