A nurse is preparing to administer acetaminophen 10 mg/kg PO every 6 hr to a toddler who weighs 26.4 lb. Available is acetaminophen 80 mg/0.8 mL liquid. How many mL should the nurse administer with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
A
Rationale
The correct answer is A: 1.2 mL. To calculate the dosage, first convert the toddler's weight from pounds to kilograms (26.4 lb ├À 2.2 kg/lb = 12 kg). Next, multiply the weight by the prescribed dose (10 mg/kg) to get the total dose (12 kg x 10 mg/kg = 120 mg). Then, use the concentration of the liquid acetaminophen (80 mg/0.8 mL) to determine how many mL contain the total dose (120 mg ├À 80 mg/mL = 1.5 mL). Round to the nearest tenth, so the nurse should administer 1.2 mL.
Choice B, C, D, E, F, and G are incorrect because they do not align with the calculated dosage based on the toddler's weight, the prescribed dose, and the concentration of the acetaminophen liquid. The correct dosage calculation requires converting the weight, determining the total
