A client with a renal calculi receives a prescription for an IV infusion of 0.9% sodium chloride 1,000 ml to be infused over 2.5 hours. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["400"]
Given:
Volume of fluid: 1000 mL
Infusion time: 2.5 hours
Formula:
Flow rate (mL/hr) = Volume (mL) / Time (hr)
Step 1: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = 1000 mL / 2.5 hr
Flow rate (mL/hr) = 400 mL/hr

Correct Answer is ["120"]
Explanation
Given:
Ordered dose of Labetalol HCl: 2 mg/minute
Concentration of Labetalol HCl: 200 mg in 200 mL (1 mg/mL)
Step 1: Calculate the infusion rate in mg/hour:
Infusion rate (mg/hour) = Ordered dose (mg/minute) x 60 minutes/hour
Infusion rate (mg/hour) = 2 mg/minute x 60 minutes/hour
Infusion rate (mg/hour) = 120 mg/hour
Step 2: Calculate the infusion rate in mL/hour:
Infusion rate (mL/hour) = Infusion rate (mg/hour) / Concentration (mg/mL)
Infusion rate (mL/hour) = 120 mg/hour / 1 mg/mL
Infusion rate (mL/hour) = 120 mL/hour
Correct Answer is ["7"]
Explanation
Given:
Ordered dose of Nesiritide: 0.01 mcg/kg/minute
Patient weight: 155.1 pounds
Bag size: 250 mL D5W
Concentration of Nesiritide: 1.5 mg
Step 1: Convert patient weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Patient weight in kg = 155.1 lbs x 0.453592 kg/lb = 70.3 kg
Step 2: Calculate the total dose of Nesiritide in mcg/minute:
Total dose (mcg/minute) = Ordered dose (mcg/kg/minute) x Patient weight (kg)
Total dose (mcg/minute) = 0.01 mcg/kg/minute x 70.3 kg
Total dose (mcg/minute) = 0.703 mcg/minute
Step 3: Convert mcg/minute to mg/hour:
Total dose (mg/hour) = Total dose (mcg/minute) x 60 minutes/hour / 1000 mcg/mg
Total dose (mg/hour) = 0.703 mcg/minute x 60 minutes/hour / 1000 mcg/mg
Total dose (mg/hour) = 0.04218 mg/hour
Step 4: Calculate the infusion rate in mL/hour:
Infusion rate (mL/hour) = Total dose (mg/hour) / Concentration (mg/mL)
Infusion rate (mL/hour) = 0.04218 mg/hour / (1.5 mg/250 mL)
Infusion rate (mL/hour) = 0.04218 mg/hour x (250 mL/1.5 mg)
Infusion rate (mL/hour) = 7.03 mL/hour
Step 5: Round to the nearest whole number:
Infusion rate (mL/hour) ≈ 7 mL/hour
