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.)

A. A 4-year-old preschooler who has status asthmaticus and a pulse oximetry of 95%. While status asthmaticus is a serious condition, a pulse oximetry reading of 95% indicates adequate oxygenation, so this child is not in immediate distress.

B. A 1-year-old infant who has roseola and a temperature of 39°C (102.2°F). While the fever requires monitoring and treatment, roseola is typically a self-limiting illness, and this temperature, while high, is not immediately life-threatening.

C. A 7-year-old child who has diabetes insipidus and a urine specific gravity of 1.002. A urine specific gravity of 1.002 indicates very dilute urine, which is concerning for diabetes insipidus and potential dehydration. This condition requires immediate attention to prevent severe dehydration and electrolyte imbalance.

D. A 10-year-old child who has sickle cell anemia and a pain rating of 6 on a 0 to 10 scale. While managing pain in sickle cell anemia is important, the child’s condition is stable, and pain relief can be addressed after assessing the more urgent case of potential dehydration in the child with diabetes insipidus.

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.
