A child weighing 44 pounds is experiencing bradycardia and receives a prescription for atropine sulfate 0.01 mg./kg intravenously STAT. The medication is supplied as supplied as 0.1 mg/mL. How many mg should the nurse administer? (Enter numeric value only. If rounding is round to the nearest tenth.)
The Correct Answer is ["0.2"]
Given:
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 ["38"]
Explanation
Given:
Volume of fluid: 75 mL
Infusion time: 30 minutes
Drop factor: 15 gtt/mL
Formula:
Flow rate (gtt/min) = (Volume (mL) / Time (min)) x Drop factor (gtt/mL)
Step 1: Calculate the infusion rate in mL/min:
Infusion rate (mL/min) = Volume (mL) / Time (min)
Infusion rate (mL/min) = 75 mL / 30 min
Infusion rate (mL/min) = 2.5 mL/min
Step 2: Calculate the flow rate in gtt/min:
Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)
Flow rate (gtt/min) = 2.5 mL/min x 15 gtt/mL
Flow rate (gtt/min) = 37.5 gtt/min
Step 3: Round to the nearest whole number:
Flow rate (gtt/min) ≈ 38 gtt/min
Correct Answer is ["105"]
Explanation
Given:
Ordered dose of Ceftazidime: 30 mg/kg/day
Infant's weight: 3,500 grams (3.5 kg)
Step 1: Calculate the total daily dose of Ceftazidime:
Total daily dose (mg) = Ordered dose (mg/kg/day) x Infant's weight (kg)
Total daily dose (mg) = 30 mg/kg/day x 3.5 kg
Total daily dose (mg) = 105 mg
