, 1. The MD orders 3500 mg IV every day for a 12-year-old patient weighing 50 ḳg. The
recommended pediatric weight-based dosing is 50–75 mg/ḳg IV every 24 hours. Is this
a safe dose?
Correct Answer:
Yes, this is a safe dose.
Calculation:
Minimum recommended dose: 50 ḳg × 50 mg/ḳg = 2500 mg/day
Maximum recommended dose: 50 ḳg × 75 mg/ḳg = 3750 mg/day
Ordered dose: 3500 mg/day
3500 mg falls within the safe range of 2500–3750 mg/day.
Rationale:
A pediatric weight-based dose is safe when the ordered dose falls within the recommended minimum and
maximum daily range.
2. The recommended dose range for acetaminophen is 10–15 mg/ḳg/dose. Give PO
every 4–6 hours and do not exceed more than 2.6 g in 24 hours. Which dose below
would be considered a safe dose, assuming they need 6 doses in a 24-hour period?
Explain your answer. Acetaminophen is available in 160 mg/5 mL and patient weighs
25 pounds.
a. 1 teaspoon every 4–6 hours
b. 1 tablespoon every 4–6 hours
c. 2 teaspoons every 4–6 hours
d. 8 mL every 4–6 hours
Correct Answer:
a. 1 teaspoon every 4–6 hours
Calculation:
25 lb ÷ 2.2 = 11.36 ḳg
Dose range: 11.36 ḳg × 10 mg/ḳg = 113.6 mg 11.36 ḳg × 15 mg/ḳg = 170.4 mg
Safe dose range = 113.6–170.4 mg per dose
