The healthcare provider prescribes enoxaparin sodium 1 mg/kg SUBQ every 12 hours for a client who weighs 132 lb. The vial is labeled, "Enoxaparin Sodium Injection, USP 100 mg per mL." How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.6"]
Here's the corrected calculation for the volume to be administered:
Dosage: 60 mg
Concentration: 100 mg/mL
Volume to administer:
Volume (mL) = Dosage (mg) / Concentration (mg/mL)
Volume (mL) = 60 mg / 100 mg/mL
Volume (mL) = 0.6 mL
Therefore, the nurse should administer 0.6 mL of enoxaparin sodium injection.

Correct Answer is ["0.8"]
Explanation
Here's how to calculate the volume (mL) of epoetin alfa the nurse should administer:
1. We know the following:
Prescribed dose: 8,200 units epoetin alfa (given)
Vial concentration: 10,000 units/mL (given from the label)
2. We need to find the volume (mL) to administer for the prescribed dose (8,200 units) considering the concentration (10,000 units/mL).
Volume to administer (mL) = Dose (units) / Concentration (units/mL)
Volume to administer (mL) = 8,200 units / 10,000 units/mL
Volume to administer (mL) = 0.82 mL (round to nearest tenth)
Therefore, the nurse should administer 0.8 mL of epoetin alfa subcutaneously.
Correct Answer is ["270"]
Explanation
Calculate the total volume infused so far:
Infusion rate: 85 mL/hour
Time elapsed: 2 hours
Total volume infused:
Volume = Rate x Time
Volume = 85 mL/hour * 2 hours = 170 mL
Calculate the remaining volume to be infused:
Initial volume of secondary infusion: 440 mL
Remaining volume:
Remaining volume = Initial volume - Volume infused
Remaining volume = 440 mL - 170 mL = 270 mL
Therefore, there are 270 mL of fluid remaining to be infused.
