Question

Determine the rate in gtt/min IV should be regulated. The order is 1000 mL D5W to infuse in 8 hours. Drop factor: 20 gtt/mL.

a) 10 gtt/min
b) 20 gtt/min
c) 2 gtt/min
d) 5 gtt/min

Answer 1

To determine the IV regulation rate, use the formula involving volume, drop factor, and time. None of the provided answer choices match the correct rate, which should be approximately 42 gtt/min after calculation.

Step-by-step explanation:

To determine the rate at which an IV should be regulated, we use the formula:

• Rate (gtt/min) = (Volume to infuse in mL × Drop factor in gtt/mL) / Time in minutes

Applying this formula to the provided question:

• Volume to infuse = 1000 mL
• Drop factor = 20 gtt/mL
• Time = 8 hours × 60 minutes/hour = 480 minutes

Now we calculate:

• Rate = (1000 mL × 20 gtt/mL) / 480 minutes
• Rate = 20000 gtt / 480 minutes
• Rate = 41.67 gtt/min (approximately)

However, none of the provided answer choices (a, b, c, or d) are correct. The correct rate should be approximately 42 gtt/min, which is not listed among the options. Therefore, the correct response would be 'None of the provided answer choices are correct.' This emphasizes the importance of double-checking calculations and provided options in test questions.
