A nurse is preparing to administer acetaminophen 15 mg/kg PO to a preschool child for fever. The child weighs 30 lb. Available is acetaminophen liquid 160 mg/5 mL. 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.)
The Correct Answer is ["6.4"]
Convert the child's weight from pounds to kilograms:
Weight in pounds: 30 lb
Conversion: 1 lb ≈ 0.454 kg
Weight in kg: 30 lb× 0.454 kg/lb =13.62 kg
30lb×0.454kg/lb=13.62kg
Calculate the dose in mg:
Dose: 15 mg/kg
15 mg/kg ×13.62kg=204.3 mg
Determine the volume to administer:
Available concentration: 160 mg/5 mL
Volume in mL:
204.3 mg ÷160 mg/5 mL
= 204.3mg×5ml ÷160mg
=6.4mL
The nurse should administer 6.4 mL of acetaminophen.

Correct Answer is B
Explanation
A. Hepatitis B (HBV): The Hepatitis B vaccine is typically completed in the infant stage, and a 5-year-old with up-to-date vaccinations would not need a booster for school entry. This is not included in the pre-kindergarten vaccine schedule.
B. Measles, mumps, and rubella (MMR): The MMR vaccine is part of the pre-kindergarten immunization schedule. A second dose is recommended between ages 4 and 6 to ensure immunity before school entry.
C. Haemophilus influenzae type B (Hib): The Hib vaccine is typically administered to infants and young children, and a 5-year-old with up-to-date immunizations would already be fully vaccinated against Hib. No booster is required at this age.
D. Pneumococcal conjugate vaccine (PCV): The PCV vaccine series is usually completed in infancy, and a 5-year-old with current vaccinations would not require a booster. This vaccine is not part of the pre-kindergarten schedule.
