A 22 lb child is prescribed ibuprofen 10 mg/kg every 6 hours.
The medication is available as 100 mg/5 mL. How many mL will you give per dose? (Round the answer to the whole number.)
Step 1 is (22 lb ÷ 2.2) = 10 kg.
Step 2 is 10 kg × 10 mg = 100 mg.
Step 3 is (100 mg ÷ 100 mg) × 5 mL = 5 mL. Answer: 5 mL

Correct Answer is ["A","B","C","D"]
Explanation
Step 1 is to convert the child's weight from pounds to kilograms: 28 lb ÷ 2.2 lb/kg = 12.727 kg.
Step 2 is to calculate the dose: 10 mg/kg × 12.727 kg = 127.27 mg.
Step 3 is to determine how many mL is needed: 127.27 mg ÷ (120 mg/5 mL) = 5.3029 mL.
Step 4 is to round to the nearest tenth: 5.3 mL. Final answer: 5.3 mL
Correct Answer is C
Explanation
Choice A rationale
The absence of creases on the plantar surface is typical of a preterm infant, not a term infant. Term infants usually have some creases.
Choice B rationale
Abundant lanugo is more common in preterm infants, while term infants may have some but not extensive lanugo.
Choice C rationale
A flexed position at rest is expected in a term neonate, as it indicates good muscle tone and neuromuscular development.
Choice D rationale
The pinna of the ear remaining folded is more indicative of a preterm infant, as term infants typically have fully formed and firmer ear cartilage.
