A child has a brain tumor. Which of the following findings should the nurse expect?
- A. Decreased head circumference
- B. Frequent headaches
- C. Increased appetite
- D. Increased blood pressure
Correct Answer: B
Rationale: Children with brain tumors commonly experience frequent headaches due to increased intracranial pressure. This pressure can result in pain and discomfort, leading to headaches as a common symptom. Other symptoms may include nausea, vomiting, changes in vision, and behavioral changes, but headaches are a prominent feature in children with brain tumors.

When the nurse is reviewing a patient's daily laboratory test results, which of the ff. electrolyte imbalances should the nurse recognize as predisposing the patient to digoxin toxicity?
- A. Hypokalemia
- B. Hyponatremia
- C. Hyperkalemia
- D. Hypernatremia
Correct Answer: A
Rationale: Hypokalemia, or low potassium levels, predisposes the patient to digoxin toxicity because potassium is essential for proper digoxin metabolism. Potassium competes with digoxin for binding sites on sodium-potassium ATPase pumps in the myocardial cells. When potassium levels are low, digoxin binding is increased, leading to an increased risk of digoxin toxicity. Monitoring and correcting hypokalemia are important in patients taking digoxin to reduce the risk of toxicity. Hyperkalemia, on the other hand, can increase the risk of digoxin toxicity by affecting electrophysiological properties of the heart, but hypokalemia is the most significant imbalance predisposing to digoxin toxicity.
