Calculate the flow rate I mL/hr. and Units/hr. (Equipment used is programmable in whole mL/hr and Show all work) Order: 25,000 units of Heparin in 250 mL to infuse at 11 mL/hr. Calculate rate in units/hr.
900 units/hr
1,000 units/hr
2.000 units/hr
1,100 units/hr
The Correct Answer is D
Given:
Total Heparin in solution: 25,000 units
Volume of solution: 250 mL
Infusion rate: 11 mL/hr
Step 1: Calculate the concentration of Heparin in the solution:
Concentration (units/mL) = Total Heparin (units) / Volume of solution (mL)
Concentration (units/mL) = 25,000 units / 250 mL
Concentration (units/mL) = 100 units/mL
Step 2: Calculate the infusion rate in units/hr:
Infusion rate (units/hr) = Infusion rate (mL/hr) x Concentration (units/mL)
Infusion rate (units/hr) = 11 mL/hr x 100 units/mL
Infusion rate (units/hr) = 1100 units/hr

Correct Answer is A
Explanation
Given:
Ordered dose of Heparin: 15 units/kg/hr
Patient weight: 82 kg
Total Heparin in solution: 25,000 units
Volume of solution: 250 mL
Step 1: Calculate the total dose of Heparin in units/hr:
Total dose (units/hr) = Ordered dose (units/kg/hr) x Patient weight (kg)
Total dose (units/hr) = 15 units/kg/hr x 82 kg
Total dose (units/hr) = 1230 units/hr
Step 2: Calculate the concentration of Heparin in the solution:
Concentration (units/mL) = Total Heparin (units) / Volume of solution (mL)
Concentration (units/mL) = 25,000 units / 250 mL
Concentration (units/mL) = 100 units/mL
Step 3: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Total dose (units/hr) / Concentration (units/mL)
Infusion rate (mL/hr) = 1230 units/hr / 100 units/mL
Infusion rate (mL/hr) = 12.3 mL/hr
Correct Answer is B
Explanation
Given:
Ordered dose of hydrocortisone: 100 mg
Concentration of hydrocortisone: 250 mg/2 mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
100 mg / Volume = 250 mg/2 mL
Step 3: Solve for the unknown volume:
Volume = 100 mg / (250 mg/2 mL)
Volume = 100 mg x (2 mL / 250 mg)
Volume = 0.8 mL
