  2. After the chemotherapy has been administered
  3. Before chemotherapy administration as a prophylactic measure
  4. Never; this antiemetic is not effective for controlling nausea and vomiting associated with chemotherapy.

Question 2

The nurse is monitoring the urine specific gravity and pH on a child receiving chemotherapy. Which urinalysis result is the goal for this child?
 
  1. Spec gravity 1.030; pH 6
  2. Spec gravity 1.030; pH 7.5
  3. Spec gravity 1.005; pH 6
  4. Spec gravity 1.005; pH 7.5

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.
