A nurse is preparing to administer dextrose 5% in water 1,000 mL IV to infuse over 6 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["167"]

To calculate the infusion rate in mL/hr for dextrose 5% in water 1,000 mL over 6 hours, you can use the following formula:

Infusion Rate (mL/hr) = Total Volume (mL) / Total Time (hr)

Infusion Rate = 1,000 mL / 6 hr ≈ 166.67 mL/hr

Rounded to the nearest whole number, the nurse should set the IV pump to deliver approximately 167 mL/hr.

Correct Answer is ["1.5"]

Explanation

First, we need to calculate the amount of cefazolin 500 mg in milligrams per milliliter (mg/mL) using the information provided:

Cefazolin concentration after reconstitution = 330 mg/mL Amount of cefazolin needed per dose = 500 mg

Now we can calculate the volume (mL) required for the dose:

Volume (mL) = Amount of cefazolin needed per dose / Cefazolin concentration after reconstitution

Volume (mL) = 500 mg / 330 mg/mL ≈ 1.52 mL

Rounded to the nearest tenth, the nurse should administer approximately 1.5 mL of cefazolin per dose.

Correct Answer is ["2.3"]

Explanation

To calculate the amount of morphine (in mL) the nurse should administer, follow these steps:

Step 1: Convert the client's weight from pounds to kilograms. 99 lb / 2.2 lb/kg ≈ 45 kg (rounded to the nearest whole number)

Step 2: Calculate the total dose based on the client's weight. 0.1 mg/kg * 45 kg = 4.5 mg

Step 3: Determine how many mL of the available morphine solution (2 mg/mL) are needed to achieve the prescribed dose. 4.5 mg ÷ 2 mg/mL = 2.25 mL

Rounded to the nearest tenth, the nurse should administer 2.3 mL of morphine.
