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 ["1.3"]
Explanation
Given:
Ordered dose of Filgrastim: 5 mcg/kg/daily
Patient weight: 176 pounds
Concentration of Filgrastim: 300 mcg/mL
Step 1: Convert patient weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Patient weight in kg = 176 lbs x 0.453592 kg/lb = 79.832 kg
Step 2: Calculate the total daily dose of Filgrastim:
Total daily dose (mcg) = Ordered dose (mcg/kg/daily) x Patient weight (kg)
Total daily dose (mcg) = 5 mcg/kg/daily x 79.832 kg
Total daily dose (mcg) = 399.16 mcg
Step 3: Calculate the volume to be administered:
Volume (mL) = Total daily dose (mcg) / Concentration (mcg/mL)
Volume (mL) = 399.16 mcg / 300 mcg/mL
Volume (mL) = 1.3305 mL
Step 4: Round to the nearest tenth:
Volume (mL) ≈ 1.3 mL
Correct Answer is ["6"]
Explanation
Given:
Ordered dose of Oxytocin: 2 milliunits/min
Concentration of Oxytocin: 20 units in 1 liter (1000 mL) = 20 units/1000 mL = 0.02 units/mL
Step 1: Convert milliunits to units:
Ordered dose (units/min) = Ordered dose (milliunits/min) / 1000 milliunits/unit
Ordered dose (units/min) = 2 milliunits/min / 1000 milliunits/unit
Ordered dose (units/min) = 0.002 units/min
Step 2: Calculate the infusion rate in units/hour:
Infusion rate (units/hour) = Ordered dose (units/min) x 60 minutes/hour
Infusion rate (units/hour) = 0.002 units/min x 60 minutes/hour
Infusion rate (units/hour) = 0.12 units/hour
Step 3: Calculate the infusion rate in mL/hour:
Infusion rate (mL/hour) = Infusion rate (units/hour) / Concentration (units/mL)
Infusion rate (mL/hour) = 0.12 units/hour / 0.02 units/mL
Infusion rate (mL/hour) = 6 mL/hour
