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 ["3"]

Explanation

Here's how to calculate the volume (mL) of penicillin G benzathine the nurse should administer:

1. We know:

Prescribed dose: 1,800,000 units (given by healthcare provider)

Concentration of penicillin G benzathine in prefilled syringe: 1,200,000 units/2 mL (given on the syringe label)

2. We need to find:

Volume to administer (mL)

3. Calculation:

To find the volume to administer, we can divide the prescribed dose (units) by the concentration (units/mL) of the medication in the syringe.

Volume (mL) = Prescribed dose (units) / Concentration (units/mL)

Plug in the values:

Volume (mL) = 1,800,000 units / (1,200,000 units/2 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 (mL) = 1,800,000 units x (2 mL / 1,200,000 units)

Volume (mL) = 3 mL (rounded to the nearest whole number as requested)

Therefore, the nurse should administer 3 mL of penicillin G benzathine intramuscularly.

Correct Answer is ["0.4"]

Explanation

Here's how to calculate the volume (mL) of ketorolac the nurse should administer:

1. We know:

Dose of ketorolac to administer: 12 mg (given)

Concentration of ketorolac in the vial: 30 mg/mL (given)

2. We need to find:

Volume to administer (mL)

3. Calculation:

Volume (mL) = Dose (mg) / Concentration (mg/mL)

Volume (mL) = 12 mg / 30 mg/mL

Volume (mL) = 0.4 mL (round to one decimal place as appropriate for medication administration)

Therefore, the nurse should administer 0.4 mL of ketorolac.
