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 D
Explanation
Choice A rationale
Having a vocabulary of 30 words is not a finding that should be reported to the provider for a 24-month-old toddler. By 24 months, most children can say 50 words or more.
Choice B rationale
Sleeping 11 to 12 hours per day is not a finding that should be reported to the provider for a 24-month-old toddler. This is a typical amount of sleep for a child this age.
Choice C rationale
Eating a large amount of food one day then very little the next is not a finding that should be reported to the provider for a 24-month-old toddler. Toddlers often have variable appetites, and it’s normal for them to eat more on some days and less on others.
Choice D rationale
Holding his breath when having a temper tantrum is a finding that should be reported to the provider for a 24-month-old toddler. While breath-holding spells can be a normal part of toddler behavior, they can also be a sign of an underlying medical condition. It’s important for the provider to evaluate this behavior to rule out any potential health concerns.
