Correct Answer is ["94"]

Explanation

Let's calculate the IV pump rate step-by-step:

1. Determine the infusion rate:
Total volume (mL) / Infusion time (hours) = Infusion rate (mL/hour)
750 mL / 8 hours = 93.75 mL/hour

2. Round to the nearest whole number:
93.75 mL/hour ≈ 94 mL/hour

Correct Answer is ["28"]

Explanation

Let's calculate the IV flow rate step-by-step:

Calculate the total infusion time in minutes:

6 hours x 60 minutes/hour = 360 minutes

Calculate the drops per minute:

Total volume (mL) x Drop factor (gtt/mL) / Infusion time (minutes) = Drops per minute (gtt/min)

1000 mL x 10 gtt/mL / 360 minutes ≈ 27.78 gtt/min

Round to the nearest whole number:

27.78 gtt/min ≈ 28 gtt/min
