A 3-month-old infant is being treated with Vancomycin for bacterial meningitis. Order: 60mg/kg/day divided every 6 hours. The infant weighs 11 pounds. The nurse first confirms safe dose. The nurse then calculates the dosage. Which one of the following is the correct SINGLE dose order for the nurse to administer?
75 mg
150 mg
60 mg
300 mg
The Correct Answer is A
Convert weight to kg: 11 lbs ÷ 2.2 = 5 kg. Calculate total daily dose: 60 mg/kg/day × 5 kg = 300 mg/day. Divide the total daily dose by the number of doses per day: 300 mg/day ÷ 4 (every 6 hours) = 75 mg per dose
Convert weight to kg: 11 lbs ÷ 2.2 = 5 kg. Calculate total daily dose: 60 mg/kg/day × 5 kg = 300 mg/day. Divide the total daily dose by the number of doses per day: 300 mg/day ÷ 4 (every 6 hours) = 75 mg per dose

Correct Answer is ["0.4"]
Explanation
To calculate the daily maintenance dose of digoxin for the infant, we first convert the ordered amount from micrograms to milligrams: 4 mcg/kg/day is equivalent to 0.004 mg/kg/day. For an infant weighing 5 kg, the daily dose would be 0.004 mg/kg/day * 5 kg = 0.02 mg/day. Now, using the concentration provided on the label, which is 0.25 mg/5 mL, we can find out how many milliliters would equate to the required daily dose. This is done by setting up a proportion: (0.25 mg / 5 mL) = (0.02 mg / X mL). Solving for X gives us X = (0.02 mg * 5 mL) / 0.25 mg, which equals 0.4 mL.
Correct Answer is C
Explanation
A. Showing pictures may not be as effective for a 4-year-old to understand the procedure and what to expect.
B. A cartoon video may not accurately depict the procedure and could create unrealistic expectations.
C. Using a doll with a sternal incision and dressing helps the child visualize and understand what will happen, making the experience less frightening.
