A client is to receive drug N at 7.8 mg/hr. The medication is mixed: 100 mg of drug N is added to 250 mL of IV fluid. At what rate should the nurse set the IV pump?

Answer and Explanation

The Correct Answer is ["19.5"]

Determine the concentration of the drug solution:

You have 100 mg of drug N in 250 mL of IV fluid.

This can be expressed as a ratio: 100 mg / 250 mL

Calculate the mL per hour needed:

The client needs 7.8 mg of drug N per hour.

Use the concentration as a conversion factor to find the mL needed:

(7.8 mg / hr) x (250 mL / 100 mg) = 19.5 mL/hr

Set the IV pump:

The IV pump should be set to infuse at 19.5 mL/hr.

Correct Answer is ["114"]

Explanation

Calculate the concentration of the reconstituted Acyclovir:

You have 500 mg of Acyclovir in 20 mL of sterile water.

Concentration = 500 mg / 20 mL = 25 mg/mL

Calculate the volume needed for the prescribed dose:

Desired dose: 350 mg

Volume (mL) = Desired dose / Concentration

Volume (mL) = 350 mg / 25 mg/mL = 14 mL

Calculate the total volume for infusion:

The 14 mL of Acyclovir is added to 100 mL of IV fluid.

Total volume = 14 mL + 100 mL = 114 mL

Determine the infusion time in hours:

The infusion is to run over 1 hour.

Calculate the IV pump rate in mL/hr:

IV pump rate (mL/hr) = Total volume (mL) / Infusion time (hr)

IV pump rate = 114 mL / 1 hr = 114 mL/hr

Correct Answer is ["7.5"]

Explanation

Identify the Desired Dose:

The client needs 6 units of insulin per hour.

Identify the Available Concentration:

The solution has 200 units of insulin in 250 mL of NSS.

Set up the Proportion:

(Desired Dose / Available Concentration) = (Rate (mL/hr) / Volume (mL))

(6 units / 200 units) = (X mL / 250 mL)

Solve for X (the Rate):

Cross-multiply: 6 units x 250 mL = 200 units x X mL

1500 = 200X

X = 1500 / 200

X = 7.5 mL/hr
