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 ["0.7"]
Explanation
Given:
Ordered dose of Filgrastim: 410 mcg SUBQ every day
Concentration of Filgrastim: 600 mcg/mL
Step 1: Set up the proportion:
Desired dose (mcg) / Volume to administer (mL) = Concentration (mcg/mL)
Step 2: Substitute the values:
410 mcg / Volume = 600 mcg/mL
Step 3: Solve for the unknown volume:
Volume = 410 mcg / (600 mcg/mL)
Volume = 410 mcg x (1 mL / 600 mcg)
Volume = 0.6833 mL
Step 4: Round to the nearest tenth:
Volume ≈ 0.7 mL
Correct Answer is ["1"]
Explanation
Given:
Ordered dose of trimethobenzamide: 100 mg IM every 6 hours
Concentration of trimethobenzamide: 200 mg/2 mL vial
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
100 mg / Volume = 200 mg/2 mL
Step 3: Solve for the unknown volume:
Volume = 100 mg / (200 mg/2 mL)
Volume = 100 mg x (2 mL / 200 mg)
Volume = 1 mL
