The healthcare provider prescribes enoxaparin 1 mg/kg SUBQ every 12 hours for a client who weighs 132 pounds. The medication is available in 60 mg/0.6 mL prefilled syringe. How many mL should the nurse administer per day? (Enter numerical value only.)
The Correct Answer is ["1.20"]
First, we need to convert the client’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.20462 pounds. So,
Weight in kg = Weight in pounds / 2.20462 = 132/ 2.20462 ≈ 59.87kg
The prescribed dosage is 1 mg/kg every 12 hours, so the total daily dosage (for 24 hours) in mg would be:
Daily dosage in mg= 2 × (Dosage per kg × Weight in kg) = 2 × (1mg/kg × 59.87kg) ≈ 119.74mg
The medication is available in a concentration of 60 mg/0.6 mL, which simplifies to 100 mg/mL. Therefore, the volume to be administered per day in mL would be:
Volume in mL=Daily dosage in mg/ Concentration in mg/mL = 119.74mg / 100mg/mL ≈ 1.20mL
So, the nurse should administer approximately 1.20 mL of enoxaparin per day. Always consult with a healthcare professional for accurate information.

Correct Answer is ["50"]
Explanation
First, let’s calculate the current infusion rate in mL/hour.
The IV solution contains 20,000 units of heparin in 500 mL, so the concentration is:
Concentration = Totalunits/ Totalvolume = 20,000units /500mL = 40units/mL
The client is currently receiving 1,800 units/hour. At a concentration of 40 units/mL, this dosage is equivalent to:
Currentrate = Dose/ Concentration = 1,800units/hour / 40units/mL = 45mL/hour
The healthcare provider prescribed an increase of 5 mL/hour in the IV rate. Therefore, the new rate should be:
Newrate = Currentrate + Increase = 45mL/hour + 5mL/hour = 50mL/hour
So, the nurse should set the infusion pump to deliver 50 mL/hour. If rounding is required, this is already rounded to the nearest whole number.
Correct Answer is ["100"]
Explanation
Here's how to calculate the infusion rate (mL/hour) for the cefazolin administration:
1. We know:
Total volume of cefazolin solution (including 0.9% sodium chloride): 50 mL (given)
Amount of cefazolin to administer: 1 gram (convert to mg for calculation) = 1 g * 1000 mg/g = 1000 mg
Infusion time: 30 minutes (given) = 30 minutes / 60 minutes/hour = 0.5 hours
2. We need to find:
Infusion rate (mL/hour)
3. Calculation:
The medication (cefazolin) is diluted in sodium chloride solution, but the total volume (50 mL) includes both. We only need to administer this entire volume over the specified time.
Infusion rate (mL/hour) = Total volume of solution (mL) / Infusion time (hours)
Infusion rate (mL/hour) = 50 mL / 0.5 hours
Infusion rate (mL/hour) = 100 mL/hour
Therefore, the nurse should program the infusion pump to deliver 100 mL/hour.
