The healthcare provider prescribes an intravenous (IV) bolus of diltiazem 0.25 mg/kg for a client with atrial fibrillation. The client weighs 178 pounds. How many mg should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["20"]

1. Convert client weight to kilograms (kg):

Client weight (lbs) = 178

We know 1 kg = 2.2 lbs

Client weight (kg) = 178 lbs / 2.2 lbs/kg = 81.36 kg (rounded to two decimal places for accuracy)

2. Calculate the total diltiazem dosage:

Dosage per kg = 0.25 mg/kg

Client weight (kg) = 81.36 kg

Total dosage (mg) = Dosage per kg * Client weight (kg)

Total dosage (mg) = 0.25 mg/kg * 81.36 kg = 20.34 mg (rounded to two decimal places for accuracy)

3. Round the dosage to the nearest whole number for administration:

Total dosage (mg) = 20.34 mg (rounded to two decimal places)

In practice, medication dosages are typically rounded to the nearest whole number for safe and accurate administration. Therefore, the nurse should administer 20 mg of diltiazem.

Correct Answer is ["1.20"]

Explanation

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,

Weightinkg = Weightinpounds / 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:

Dailydosageinmg= 2 × (Dosageperkg × Weightinkg) = 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:

VolumeinmL=Dailydosageinmg/ Concentrationinmg/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 ["0.64"]

Explanation

Here's how to calculate the volume of methylprednisolone the nurse should administer:

1. We know:

Dose to administer: 40 mg (given)

Concentration of the medication: 125 mg per 2 mL (given from the vial label)

2. We need to find:

Volume of medication to administer (mL)

Calculation:

We can set up a proportion to find the volume needed for the desired dose:

Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)

Rearrange the formula to solve for the volume:

Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)

Plug in the values:

Volume to administer (mL) = 40 mg / (125 mg/2 mL)

Important note: We can divide the concentration by 2 mL because we only need the medication concentration, not the total volume in the vial (which is 2 mL).

Volume to administer (mL) = 40 mg / 62.5 mg/mL (round the concentration to nearest tenth for easier calculation)

Volume to administer (mL) = 0.64 mL (round to nearest hundredth)

Therefore, the nurse should administer 0.64 mL of methylprednisolone.
