A child receiving chemotherapy weighing 29.4 kg
Question 1 of 5
A nurse is preparing to administer ondansetron 0.15 mg/kg IV to a 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?
Correct Answer: A
Rationale:
To calculate the dose, we first multiply the child's weight (29.4 kg) by the dose (0.15 mg/kg) to get 4.41 mg. Next, we convert mg to mL using the available concentration of 4 mg/2mL. This gives us 2.205 mL, which can be rounded to 2.2 mL.
Therefore, choice A (2.2 mL) is correct.
Choice B (2.0 mL) is incorrect because it does not account for the accurate dose calculation.
Choice C (2.5 mL) is incorrect as it overestimates the dose based on the calculated value.
Choice D (2.1 mL) is also incorrect because it underestimates the dose.
