A nurse is preparing to administer ondansetron 0.15 mg/kg IV to child who is receiving chemotherapy and weighs 29.4 kg. Available is ondansetron 4 mg/2 mL solution.
How many mL should the nurse administer?
The Correct Answer is ["2.2"]
Step 1 is to calculate the total dose of ondansetron required. This is done by multiplying the child’s weight by the dose per kilogram. So, 29.4 kg × 0.15 mg/kg = 4.41 mg.
Step 2 is to calculate the volume of the solution required. This is done by dividing the total dose by the concentration of the solution. So, 4.41 mg ÷ (4 mg/2 mL) = 2.205 mL. The final calculated answer is that the nurse should administer approximately 2.2 mL of the ondansetron solution.

Correct Answer is A
Explanation
The correct answer is Choice A.
Choice A rationale: Increased restlessness in a toddler with a full-thickness burn may indicate hypoxia, pain, or shock. These conditions require immediate medical attention to prevent further complications and ensure proper management of the burn injury.
Choice B rationale: A respiratory rate of 25/min is within the normal range for toddlers (20-30 breaths per minute). This finding does not indicate an immediate concern that requires reporting to the provider.
Choice C rationale: Bowel sounds of 20/min are within the normal range (5-30 sounds per minute). This finding does not indicate any gastrointestinal complications that need to be reported to the provider.
Choice D rationale: Urinary output of 35 mL/hr is within the normal range for toddlers (1-2 mL/kg/hr). This finding indicates adequate kidney function and hydration status, so it does not require immediate reporting.
