A client retums from the post anesthesia care unit (PACU) with a bag of intravenous (IV) fluids that has 630 mL remaining in the 1,000 mL bag. The prescription reads, "Continue the present IV over the next 7 hours." The IV administration set delivers 10 gtt/mL. The nurse should regulate the infusion to deliver how many drops/minute to accomplish the new prescription? (Enter numeric value only).
Answer and Explanation

The Correct Answer is ["15"]

Here's what we know:

Volume remaining in the bag: 630 mL

Total volume to be infused (remaining volume): 630 mL (since we're using the remaining volume)

Infusion time: 7 hours

Drop factor (delivery rate per mL): 10 gtt/mL

We need to find:

Infusion rate (gtt/min)

Steps to solve:

Convert hours to minutes:

Infusion time (hours) = 7

Conversion factor: 1 hour = 60 minutes

Infusion time (minutes) = 7 hours x 60 minutes/hour = 420 minutes

Calculate the required infusion rate (gtt/min):

Total volume to be infused (mL) = 630 mL

Drop factor (gtt/mL) = 10 gtt/mL

Infusion time (minutes) = 420 minutes

Infusion rate (gtt/min) = (Total volume (mL) / Infusion time (minutes)) x Drop factor (gtt/mL)

Infusion rate (gtt/min) = (630 mL / 420 minutes) x 10 gtt/mL

Infusion rate (gtt/min) = 15 gtt/min (rounded to the nearest whole number)

Therefore, the nurse should regulate the infusion to deliver approximately 15 drops/minute.

Correct Answer is ["2.4"]

Explanation

Here's how to calculate the volume (mL) of the reconstituted cefazolin solution the nurse should administer for each dose:

1. We know the following:

Prescribed dose: 800 mg cefazolin (given)

Vial information:

Contains 1 gram cefazolin (given) = 1000 mg (since 1 gram = 1000 milligrams)

Reconstituted with 2.5 mL sterile water for injection (given)

Yields a total volume of 3.0 mL (given)

2. We need to find the concentration of cefazolin (mg/mL) in the reconstituted solution.

3. Then, we can find the volume (mL) to administer for the prescribed dose (800 mg) considering the concentration.

Steps:

a. Calculate the concentration after reconstitution:

Total volume after reconstitution = 3.0 mL (given)

Total amount of cefazolin after reconstitution = 1 gram (from the vial) = 1000 mg

Concentration (mg/mL) = Total amount of medication (mg) / Total volume after reconstitution (mL)

Concentration (mg/mL) = 1000 mg / 3.0 mL

Concentration (mg/mL) = 333.33 mg/mL (round to one decimal place)

b. Calculate the volume to administer:

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

Volume to administer (mL) = 800 mg / 333.33 mg/mL

Volume to administer (mL) = 2.4 mL (round to nearest tenth)

Therefore, the nurse should administer approximately 2.4 mL of the reconstituted cefazolin solution intramuscularly every 6 hours.

Correct Answer is ["111"]

Explanation

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.
