A client is to receive antibiotics 1,000,000 units IV. Package instructions are to mix the medication with enough sterile water to yield a concentration of 250,000 units per 4mL. After withdrawing the required dose from the vial, package instruction are to further dilute in 100mL of IV fluid and run it over 1 hour. At what raet should the nurse set the IV pump?

Answer and Explanation

The Correct Answer is ["116"]

Let's calculate the IV pump rate step-by-step:

1. Determine the total volume of the medication:
The desired dosage is 1,000,000 units.
The concentration of the reconstituted medication is 250,000 units per 4 mL.
To find the total volume needed, divide the desired dosage by the concentration:
1,000,000 units / 250,000 units/4 mL = 4 x 4 mL = 16 mL

2. Calculate the final volume after dilution:
The reconstituted medication (16 mL) is further diluted with 100 mL of IV fluid.
The total volume after dilution is 16 mL + 100 mL = 116 mL.

3. Determine the infusion rate:
The infusion time is given as 1 hour.
To calculate the infusion rate, divide the total volume by the infusion time:
116 mL / 1 hour = 116 mL/hour

Explanation

To determine the correct IV pump rate for the heparin infusion, follow these steps:

1. Calculate the concentration of heparin in units per mL:
The concentration is 25000 units in 250 mL.
Therefore, 25000 units / 250 mL = 100 units/mL.

2. Determine the infusion rate in mL per hour:
The ordered dose is 1100 units per hour.
Using the concentration, 1100 units/hr / 100 units/mL = 11 mL/hr.

Correct Answer is ["18"]

Explanation

To determine the correct IV pump rate for the heparin infusion, follow these steps:

1. Convert the patient’s weight from pounds to kilograms:
1 pound = 0.453592 kilograms
220 pounds x 0.453592 = 99.79 kilograms (rounded to two decimal places)

2. Calculate the dosage in units per hour:
18 units/kg/hr x 99.79 kg = 1796.22 units/hr

3. Determine the volume of heparin solution needed per hour:
The medication is supplied as 25000 units in 250 mL.
Therefore, the concentration is 100 units/mL.
1796.22 units/hr / 100 units/mL = 17.96 mL/hr

4. So, the nurse should set the IV pump to 18 mL/hour (rounded to the nearest whole number).
