A client is receive a continuous Heparin infusion at 950 units per hour. Pharmacy supplies Heparin in a concentration of 25.000 units per 250mL of IV fluid. Calculate the rate at which the nurse should set the IV pump. (Use a preceding zero if it applies. Do not use trailing zeros. Round to the nearest tenth).
The Correct Answer is ["9.5"]
Identify the Desired Dose:
The client needs 950 units of Heparin per hour.
Identify the Available Concentration:
The pharmacy provides Heparin at a concentration of 25,000 units in 250 mL of IV fluid.
Set up the Proportion:
(Desired Dose / Available Concentration) = (Rate (mL/hr) / Volume (mL))
(950 units / 25,000 units) = (X mL / 250 mL)
Solve for X (the Rate):
Cross-multiply: 950 units x 250 mL = 25,000 units x X mL
237,500 = 25,000X
X = 237,500 / 25,000
X = 9.5 mL/hr

Correct Answer is ["5"]
Explanation
Determine the concentration of the insulin solution:
There are 100 units of insulin in 100 mL of IV fluid.
Concentration = 100 units / 100 mL = 1 unit/mL
Calculate the volume (in mL) needed per hour:
The client needs 5 units per hour.
Since the concentration is 1 unit/mL, this means the client needs 5 mL per hour.
Set the IV pump:
The IV pump should be set to infuse at 5 mL/hr.
Correct Answer is ["1.5"]
Explanation
Determine the Desired Dose:
The healthcare provider prescribed 750 mg of metformin.
Determine the Available Dose:
Each tablet contains 500 mg of metformin.
Calculate the Number of Tablets:
Number of Tablets = Desired Dose / Available Dose
Number of Tablets = 750 mg / 500 mg
Number of Tablets = 1.5
