,1. The MD orders 3500 mg IV every day for a 12-year-old patient weighing 50 kg. The
recommended pediatric weight-based dosing is 50–75 mg/kg IV every 24 hours. Is this
a safe dose?
Correct Answer:
Yes, this is a safe dose.
Calculation:
Minimum recommended dose: 50 kg × 50 mg/kg = 2500 mg/day
Maximum recommended dose: 50 kg × 75 mg/kg = 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/kg/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 kg
, Dose range: 11.36 kg × 10 mg/kg = 113.6 mg 11.36 kg × 15 mg/kg = 170.4 mg
Safe dose range = 113.6–170.4 mg per dose
Medication concentration: 160 mg / 5 mL
1 teaspoon = 5 mL = 160 mg
160 mg falls within the safe dose range.
Daily total if given 6 times: 160 mg × 6 = 960 mg/day
960 mg/day is below the 2.6 g/day maximum.
Rationale:
The safest choice is the dose that falls within the recommended mg/kg range and does
not exceed the maximum total daily dose.
3. Convert 37 degrees Celsius to Fahrenheit:
Correct Answer:
98.6°F
Calculation:
°F = °C × 9/5 + 32 37 × 9/5 + 32 = 98.6°F
Rationale:
Celsius is converted to Fahrenheit by multiplying by 9/5 and adding 32.
4. How many pounds are in 55 kg?
Correct Answer:
121 pounds
Calculation:
55 kg × 2.2 lb/kg = 121 lb
Rationale:
To convert kilograms to pounds, multiply the weight in kilograms by 2.2.
