The healthcare provider prescribes daptomycin 9 mg/kg/day IV for a child who weighs 44 pounds. How many mg of the medication should the nurse prepare to administer? (Enter numeric value only.)
The Correct Answer is ["180"]
Given:
Ordered dose of Daptomycin: 9 mg/kg/day
Child's weight: 44 pounds
Step 1: Convert child's weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Child's weight in kg = 44 lbs x 0.453592 kg/lb = 19.958 kg
Step 2: Calculate the total daily dose of Daptomycin:
Total daily dose (mg) = Ordered dose (mg/kg/day) x Child's weight (kg)
Total daily dose (mg) = 9 mg/kg/day x 19.958 kg
Total daily dose (mg) = 179.622 mg
Round off to 180 mg

Ordered dose of Atropine Sulfate: 0.01 mg/kg
Child's weight: 44 pounds
Step 1: Convert child's weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Child's weight in kg = 44 lbs x 0.453592 kg/lb = 19.958 kg
Step 2: Calculate the total dose of Atropine Sulfate:
Total dose (mg) = Ordered dose (mg/kg) x Child's weight (kg)
Total dose (mg) = 0.01 mg/kg x 19.958 kg
Total dose (mg) = 0.19958 mg
Step 3: Round to the nearest tenth:
Total dose (mg) ≈ 0.2 mg
Correct Answer is ["60"]
Explanation
Given:
Ordered dose: 25 mL PO every 6 hours PRN
Medication label: "Acetaminophen and Codeine Phosphate Oral Solution, USP: 120/12 mg per 5 mL"
Step 1: Determine the concentration of codeine in the solution:
Concentration of Codeine = Amount of Codeine / Volume of Solution
Concentration of Codeine = 12 mg / 5 mL
Concentration of Codeine = 2.4 mg/mL
Step 2: Calculate the amount of codeine per dose:
Amount of Codeine per Dose = Concentration of Codeine x Volume per Dose
Amount of Codeine per Dose = 2.4 mg/mL x 25 mL
Amount of Codeine per Dose = 60 mg
