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.)
Answer and Explanation

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 ["699"]

Explanation

First, we need to convert the client’s weight from pounds to kilograms since the dosage is prescribed in mL/kg.

We know that 1 kg is approximately 2.20462 pounds. So,

Weightinkg= Weightinpounds/2.20462 ​= 154 / 2.20462 ​≈ 69.85kg

The prescribed dosage is 30 mL/kg, so the total volume in mL would be:

VolumeinmL= Dosageperkg × Weightinkg=30mL/kg × 69.85kg ≈ 2095.5mL

The medication is to be administered over 3 hours. Therefore, the rate in mL/hour would be:

RateinmL/hour = VolumeinmL / Timeinhours ​= 2095.5mL/3hours ​ ≈ 698.5mL/hour

So, the nurse should program the infusion pump to deliver approximately 699 mL/hour.

Correct Answer is ["18"]

Explanation

Here's how to calculate the volume (mL/hour) the nurse should program the infusion pump to deliver heparin:

1. We know:

Heparin dose rate: 1,400 units/hour (given by healthcare provider)

Heparin concentration in the IV bag: 20,000 units per 250 mL (given on the label)

2. We need to find:

Volume delivery rate (mL/hour)

3. Calculation:

To find the volume rate, we can divide the heparin dose rate (units/hour) by the heparin concentration (units/mL)

Volume rate (mL/hour) = Heparin dose rate (units/hour) / Heparin concentration (units/mL)

Plug in the values:

Volume rate (mL/hour) = 1,400 units/hour / (20,000 units / 250 mL)

Important note: We can rearrange the fraction with the concentration term because we are dividing by units/mL, which is equivalent to multiplying by mL/units. So, effectively, we are multiplying by the reciprocal of the concentration.

Volume rate (mL/hour) = 1,400 units/hour x (250 mL / 20,000 units)

Volume rate (mL/hour) = 17.5 mL/hour (round to nearest whole number)

Therefore, the nurse should program the infusion pump to deliver 18 mL/hour.
