The nurse is preparing a dose of ketorolac 12 mg IV using a 1 mL vial containing 30 mg/mL. How many mL should the nurse administer? (Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["0.4"]

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

1. Dose of ketorolac to administer:

Dose = 12 mg (given)

2. Concentration of ketorolac in the vial:

Concentration = 30 mg/mL (given)

3. We need to find the volume (mL) containing the prescribed dose (12 mg) considering the concentration (30 mg/mL) in the vial.

Volume to administer (mL): Dose (mg) / Concentration (mg/mL)

Volume to administer (mL): 12 mg / 30 mg/mL

Volume to administer (mL) = 0.4 mL (round to nearest tenth)

Therefore, the nurse should administer approximately 0.4 mL of ketorolac intravenously.

Correct Answer is ["1.8"]

Explanation

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

Calculate the total dose of diazepam for the child:

Dose per kg: 0.3 mg/kg (given)

Child's weight: 30 kg (given)

Total dose (mg) = Dose per kg (mg/kg) x Child's weight (kg)

Total dose (mg) = 0.3 mg/kg * 30 kg

Total dose (mg) = 9 mg (round to nearest whole number)

Concentration of the medication:

The medication is available in 5 mg/mL vials (given).

Calculate the volume to administer:

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

Volume to administer (mL) = 9 mg / 5 mg/mL

Volume to administer (mL) = 1.8 mL (round to nearest tenth)

Therefore, the nurse should administer approximately 1.8 mL of diazepam intravenously.

Correct Answer is ["200"]

Explanation

Here's why:

The entire dose (400 mg) is contained within the 200 mL bag.

The information doesn't suggest the bag needs to be emptied completely during the infusion.

Our goal is to deliver the 400 mg dose over the 1-hour infusion period.

Therefore, the nurse should program the infusion pump to deliver the entire volume of the bag (200 mL) containing the medication over the 1-hour timeframe.

Calculation:

Volume to deliver (mL/hr) = Total volume of bag (mL) / Infusion time (hours)

Volume to deliver (mL/hr) = 200 mL / 1 hour

Volume to deliver (mL/hr) = 200 mL/hr

Therefore, the nurse should program the infusion pump to deliver 200 mL/hr.
