Answer :
Sure! Let's break down the solution for each part of the question step-by-step.
Part 1: Enoxaparin Dosage Calculation
1. Dose ordered: The prescription is for 60 mg of enoxaparin to be given subcutaneously twice a day (BID).
2. Available concentration: You have enoxaparin with a concentration of 75 mg/ml.
3. Calculate the volume to give per dose: To figure out how many milliliters to administer per dose, you divide the ordered dose by the concentration.
[tex]\[
\text{ml per dose} = \frac{\text{dose ordered (mg)}}{\text{dose concentration (mg/ml)}} = \frac{60 \text{ mg}}{75 \text{ mg/ml}} = 0.8 \text{ ml}
\][/tex]
So, per dose, you would give 0.8 ml of enoxaparin.
Part 2: Infusion Rate Calculation
1. Volume to infuse: The total volume to infuse is 2.55 liters of 1/2 NS with 20 mEq KCL.
2. Convert the volume to milliliters: Since there are 1000 milliliters in a liter, you would convert the volume from liters to milliliters.
[tex]\[
\text{infusion volume (ml)} = 2.55 \text{ L} \times 1000 \text{ ml/L} = 2550 \text{ ml}
\][/tex]
3. Infusion time: The infusion is to be completed over 15 hours.
4. Calculate the infusion rate: To find out how many milliliters per hour to program the pump:
[tex]\[
\text{ml/hr} = \frac{\text{infusion volume (ml)}}{\text{infusion time (hr)}} = \frac{2550 \text{ ml}}{15 \text{ hr}} = 170 \text{ ml/hr}
\][/tex]
Therefore, you should set the pump to infuse at a rate of 170 ml/hour.
In summary:
- You give 0.8 ml of enoxaparin per dose.
- Set the infusion pump at a rate of 170 ml/hr.

- You give 0.8 ml of enoxaparin per dose.
- Set the infusion pump at a rate of 170 ml/hr.
