A nurse is preparing to administer 10 mg/kg acetaminophen (Tylenol) PO to a toddler who weighs 9 kg (19.8 lb). Available is acetaminophen liquid 160 mg/5 mL. How many mL should the nurse plan to administer? (Round the answer to the nearest tenth.)
Explanation
Pediatric medication administration requires careful weight-based calculations to ensure both safety and effectiveness. For drugs like acetaminophen, accurate conversion from milligrams to milliliters is crucial to avoid underdosing or overdosing in children.
Rationale for correct answer:
Step 1: Calculate the Total Dose
First, determine the total dose of acetaminophen the toddler should receive based on their weight.
- Formula: Total Dose = Weight (kg) × Dose per kg
 - Calculation: 9kg×10mg/kg=90mg
 
Step 2: Calculate the Volume to Administer
Next, use the total dose and the concentration of the available medication to find the volume to be administered. The concentration is 160 mg in 5 mL.
- Formula: Volume = Total Dose ÷ Concentration
 - Calculation:
	
- Find the concentration: 160mg÷5mL=32mg/mL
 - Find the volume: 90mg÷32mg/mL=2.8125mL
 
 
Step 3: Round to the Nearest Tenth
Round the final answer to the nearest tenth as requested.
- Correct answer: 2.8125mL≈2.8mL
 
Take-home points:
- Always calculate pediatric doses using the child’s weight in kilograms and the prescribed mg/kg dosage.
 - Convert the supplied concentration into mg/mL before calculating the required volume.
 - For a 9 kg toddler receiving 10 mg/kg acetaminophen, the correct dose is 2.8 mL of a 160 mg/5 mL solution.
