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

Correct Answer is ["600"]
Explanation
Given:
Volume of fluid: 200 mL
Infusion time: 20 minutes
Formula:
Flow rate (mL/hr) = Volume (mL) / Time (hr)
Step 1: Convert infusion time from minutes to hours:
Infusion time (hr) = 20 minutes / 60 minutes/hr
Infusion time (hr) = 1/3 hour
Step 2: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = 200 mL / (1/3) hr
Flow rate (mL/hr) = 200 mL x (3/1) hr
Flow rate (mL/hr) = 600 mL/hr
Correct Answer is ["42"]
Explanation
Given:
Volume of fluid: 1 liter = 1000 mL
Infusion time: 8 hours
Drop factor: 20 gtt/mL
Formula:
Flow rate (gtt/min) = (Volume (mL) / Time (hr)) x Drop factor (gtt/mL) / 60 min/hr
Step 1: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Volume (mL) / Time (hr)
Infusion rate (mL/hr) = 1000 mL / 8 hr
Infusion rate (mL/hr) = 125 mL/hr
Step 2: Calculate the flow rate in gtt/min:
Flow rate (gtt/min) = (Infusion rate (mL/hr) x Drop factor (gtt/mL)) / 60 min/hr
Flow rate (gtt/min) = (125 mL/hr x 20 gtt/mL) / 60 min/hr
Flow rate (gtt/min) = 2500 gtt/hr / 60 min/hr
Flow rate (gtt/min) = 41.667 gtt/min
Step 3: Round to the nearest whole number:
Flow rate (gtt/min) ≈ 42 gtt/min
