, A 74.0

An order is written for 500 mL of NS to infuse at 40 gtt/min. How long would it take to
infuse the NS if the set delivers 10 gtt/mL?
A 40 minutes
B 125 minutes
C 50 minutes
D 100 minutes - ✔️✔️125 minutes
10 gtt/mL means 10 drops per mL. So for 500 mL you will get: 10 X 500 = 5,000 drops.
The flow rate is 40 gtt/min, which means 40 drops per minute, so divide total drops by
40 to get the number of minutes: 5,000/40 = 125.
Convert 5.5 kg to pounds.
A 1.21 lb
B 55 lb
C 12.1 lb

A 12.5%
B 0.8%
C 8.0%
D 0.08% - ✔️✔️0.8%
Percent means parts per hundred. 1/125 = x/100 which means 125x = 100 which
means x = 0.8
