Answer to Question 1

Correct Answer: 3
Rationale: The antiemetic ondansetron (Zofran) should be administered before chemotherapy as a prophylactic measure. Giving it after the child has nausea or at the end of chemotherapy treatment does not help with preventing nausea. It is the drug of choice for controlling nausea caused by chemotherapy agents.

Answer to Question 2

Correct Answer: 4
Rationale: Because the breakdown of malignant cells releases intracellular components into the blood and electrolyte imbalance causes metabolic acidosis, the urine specific gravity should remain at less than 1.010 and the pH at 7 to 7.5. A specific gravity higher than 1.010 can mean fluid intake is not high enough, and a pH of less than 7 means acidosis.
