Passage / Scenario
Child weighs 55 lbA nurse is preparing to administer ibuprofen 10 mg/kg PO to a child. The child weighs 55 lb. Available is ibuprofen 100 mg/5 mL solution. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
12.5 mL
Rationale
To determine the correct dose of ibuprofen for the child, we first convert the child's weight from pounds to kilograms (55 lb ├À 2.2 = 25 kg). Then, we calculate the dose: 10 mg/kg ├ù 25 kg = 250 mg. Next, we convert the dose from mg to mL using the available concentration: 250 mg ├À 100 mg/5 mL = 12.5 mL. Therefore, the nurse should administer 12.5 mL of ibuprofen. The other choices are incorrect because they do not follow the correct calculations based on the child's weight and the concentration of the available ibuprofen solution.
