The nurse plans to provide the next shift with the intravenous (IV) fluid balance for a client who had a 440 mL secondary infusion that was started 2 hours ago at a rate of 85 mL/hour via an infusion pump. What is the remaining volume to be infused? (Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["270"]

Calculate the total volume infused so far:

Infusion rate: 85 mL/hour

Time elapsed: 2 hours

Total volume infused:

Volume = Rate x Time

Volume = 85 mL/hour * 2 hours = 170 mL

Calculate the remaining volume to be infused:

Initial volume of secondary infusion: 440 mL

Remaining volume:

Remaining volume = Initial volume - Volume infused

Remaining volume = 440 mL - 170 mL = 270 mL

Therefore, there are 270 mL of fluid remaining to be infused.

Correct Answer is ["75"]

Explanation

The prescribed dosage is 15 mL every 12 hours, so the total daily dosage in mL would be:

DailydosageinmL = 2 × Dosageperdose = 2 ×15mL = 30mL

The medication is available in a concentration of 12.5 mg/5 mL. Therefore, the total daily dosage in mg would be:

Dailydosageinmg=DailydosageinmL×Concentrationinmg/mL=30mL×5mL12.5mg=75mg

So, the client receives a total daily dose of 75 mg of diphenhydramine.

Correct Answer is ["42"]

Explanation

Here's how to calculate the infusion rate (gtt/min) for the azithromycin administration:

1. We know:

Total volume of solution (including azithromycin and normal saline): 500 mL (given)

Infusion duration: 2 hours (given)

IV administration set drip rate: 10 gtt/mL (given)

2. We need to find:

Infusion rate (gtt/min)

Steps:

Calculate the total volume to be infused per hour:

Volume per hour (mL) = Total volume (mL) / Infusion time (hours)

Volume per hour (mL) = 500 mL / 2 hours

Volume per hour (mL) = 250 mL/hour

Calculate the infusion rate in gtt/min:

Infusion rate (gtt/min) = Volume per hour (mL) x Drip rate (gtt/mL) / 60 minutes/hour (convert hour to minutes)

Infusion rate (gtt/min) = 250 mL/hour x 10 gtt/mL / 60 minutes/hour

Infusion rate (gtt/min) = 41.67 gtt/min (round to nearest whole number)

Therefore, the nurse should regulate the infusion at approximately 42 gtt/min.
