A microdrip set delivers 60 drops/mL. The ordered rate is 80 mL/hour. What gravity rate is needed?
- A160 drops/minute
- B20 drops/minute
- C80 drops/minute
- D60 drops/minute
Show answer and explanations
Answer
C
A
160 drops/minute doubles the rate.
B
20 drops/minute applies a 15 drops/mL macrodrip factor instead of the 60 drops/mL microdrip set.
C
80 mL/hour x 60 drops/mL / 60 minutes = 80 drops/minute; with a microdrip set, drops/minute equals mL/hour.
D
60 drops/minute uses the drop factor as the rate and delivers only 60 mL/hour.
