A client is receiving a 200 ml bolus of 0.9% sodium chloride to be infused over 20 minutes. The nurse should set the infusion pump deliver how many mL/hour? (Enter numeric value only.)
The Correct Answer is ["600"]
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 ["9"]
Explanation
Given:
Ordered dose of insulin: 0.1 units/kg
Patient weight: 200 pounds
Step 1: Convert patient weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Patient weight in kg = 200 lbs x 0.453592 kg/lb = 90.718 kg
Step 2: Calculate the total dose of insulin:
Total dose (units) = Ordered dose (units/kg) x Patient weight (kg)
Total dose (units) = 0.1 units/kg x 90.718 kg
Total dose (units) = 9.0718 units
Step 3: Round to the nearest whole number:
Total dose (units) ≈ 9 units
Correct Answer is ["1.3"]
Explanation
Given:
Ordered dose of amoxicillin: 25 mg/kg/day
Child's weight: 18 pounds
Concentration of amoxicillin suspension: 400 mg/5 mL
Step 1: Convert child's weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Child's weight in kg = 18 lbs x 0.453592 kg/lb = 8.164656 kg
Step 2: Calculate the total daily dose of amoxicillin:
Total daily dose (mg) = Ordered dose (mg/kg/day) x Child's weight (kg)
Total daily dose (mg) = 25 mg/kg/day x 8.164656 kg
Total daily dose (mg) = 204.1164 mg/day
Step 3: Calculate the dose per administration:
Since the medication is given every 12 hours, there are 2 administrations per day.
Dose per administration (mg) = Total daily dose (mg) / Number of administrations per day
Dose per administration (mg) = 204.1164 mg/day / 2 administrations/day
Dose per administration (mg) = 102.0582 mg
Step 4: Calculate the volume to be administered per dose:
Volume (mL) = Dose per administration (mg) / Concentration (mg/mL)
Volume (mL) = 102.0582 mg / (400 mg/5 mL)
Volume (mL) = 102.0582 mg x (5 mL / 400 mg)
Volume (mL) = 1.2757275 mL
Step 5: Round to the nearest tenth:
Volume (mL) ≈ 1.3 mL
