Nursing Elites

1. A nurse caring for a client with hypocalcemia would expect to note which of the following changes on the electrocardiogram?

• A. Widened T wave
• B. Prominent U wave
• C. Prolonged QT interval
• D. Shortened ST segment

Correct answer: C

Rationale: In hypocalcemia, a decreased level of calcium can lead to a prolonged QT interval on the ECG due to its role in myocardial repolarization. A widened T wave (Choice A) is typically seen in hyperkalemia. A prominent U wave (Choice B) is associated with hypokalemia. A shortened ST segment (Choice D) is not a typical ECG finding in hypocalcemia.

2. A client with hyperparathyroidism is at risk for which of the following complications?

• A. Hypocalcemia
• B. Osteoporosis
• C. Hypokalemia
• D. Hyponatremia

Correct answer: B

Rationale: A client with hyperparathyroidism is at risk for osteoporosis, not hypocalcemia, hypokalemia, or hyponatremia. Hyperparathyroidism results in increased levels of parathyroid hormone, which causes excessive breakdown of bone tissue to release calcium into the bloodstream. This process can lead to weakened bones and an increased risk of osteoporosis. Hypocalcemia is unlikely in hyperparathyroidism as the condition is characterized by elevated calcium levels due to the abnormal activity of the parathyroid glands. Hypokalemia and hyponatremia are not directly associated with hyperparathyroidism; they are more commonly linked to other conditions affecting potassium and sodium levels in the body.

3. A client with a diagnosis of diabetic ketoacidosis (DKA) is being treated in the ER. Which finding would a nurse expect to note as confirming this diagnosis?

• A. Elevated blood glucose level and a low plasma bicarbonate
• B. Decreased urine output
• C. Increased respirations and an increase in pH
• D. Comatose state

Correct answer: A

Rationale: The correct answer is A: Elevated blood glucose level and a low plasma bicarbonate. Diabetic ketoacidosis (DKA) is characterized by hyperglycemia, ketosis, and metabolic acidosis, reflected by a low plasma bicarbonate. Elevated blood glucose levels are a hallmark of DKA due to the body's inability to use glucose properly. Choices B, C, and D are incorrect. Decreased urine output is not a specific finding associated with DKA. Increased respirations and an increase in pH are not typical in DKA; in fact, respiratory compensation for the metabolic acidosis in DKA leads to Kussmaul breathing (deep, rapid breathing). A comatose state may occur in severe cases of DKA but is not a confirming finding for the diagnosis.

4. A client with hypothyroidism is receiving levothyroxine therapy. The healthcare provider should monitor for which of the following signs of medication overdose?

• A. Bradycardia
• B. Weight gain
• C. Tachycardia
• D. Cold intolerance

Correct answer: C

Rationale: The correct answer is C: Tachycardia. Tachycardia is a sign of levothyroxine overdose, indicating that the dose may need to be adjusted. Bradycardia (Choice A) is a sign of hypothyroidism, not an overdose of levothyroxine. Weight gain (Choice B) and cold intolerance (Choice D) are also symptoms of hypothyroidism, not medication overdose.

5. A client with hyperparathyroidism is receiving dietary instructions. Which of the following foods should the client avoid?

• A. Milk
• B. Bananas
• C. Spinach
• D. Processed meats

Correct answer: A

Rationale: In hyperparathyroidism, there are already elevated calcium levels in the body. Therefore, clients should avoid high-calcium foods like milk to prevent further increase in calcium levels. Bananas, spinach, and processed meats do not have significant calcium content and do not need to be avoided specifically in hyperparathyroidism.
