The healthcare provider prescribes a liter of normal saline 0.9% IV to be infused over 9 hours for a client who is NPO. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number).

Answer and Explanation

The Correct Answer is ["111"]

Here's how to calculate the infusion rate (mL/hour) for the normal saline administration:

We know:

Total volume of normal saline solution: 1 liter (given) = 1000 mL (convert liters to mL)

Infusion time: 9 hours (given)

We need to find:

Infusion rate (mL/hour)

Calculation:

Infusion rate (mL/hour) = Total volume of solution (mL) / Infusion time (hours)

Infusion rate (mL/hour) = 1000 mL / 9 hours

Infusion rate (mL/hour) = 111.11 mL/hour (round to nearest whole number)

Therefore, the nurse should program the infusion pump to deliver 111 mL/hour.

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.

Correct Answer is ["1.2"]

Explanation

Here's the breakdown of the calculation:

Convert the prescribed dose to milligrams (mg):

We are given the dose in mcg (micrograms). To match the concentration of the medication (mg/mL), we need to convert mcg to mg.

Conversion factor: 1 mg = 1000 mcg

Dose (mg) = Prescribed dose (mcg) / Conversion factor

Dose (mg) = 0.6 mg / 1000 mcg/mg

Dose (mg) = 0.0006 mg (convert to mg for easier calculation)

Calculate the volume to administer:

We know the dose (mg) and the concentration (mg/mL) of the medication in the vial.

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

Volume (mL) = 0.0006 mg / (500 mcg/mL) (convert mcg/mL to mg/mL for consistency)

Volume (mL) = 0.0006 mg / (0.5 mg/mL)

Volume (mL) = 0.0012 mL (round to one decimal place as appropriate for medication administration)

Adjust for unit size:

The medication vial contains 2 mL, and we calculated a volume of 0.0012 mL.

However, it's not possible or safe to administer such a small fraction of the vial content.

In practice, the nurse would need to administer the smallest measurable volume possible using this specific vial.

Since the vial contains 2 mL, 1.2 mL is the lowest whole number volume that can be accurately measured and administered from this vial.

Therefore, while the calculated dose based on the prescribed amount is 0.0012 mL, the nurse should administer 1.2 mL from the available 2 mL vial.
