PTCB Practice Test 2 Questions and
Answers (100% Pass)

The percent equivalent of a 1:125 ratio is: - Answer✔️✔️-0.8%



Percent means parts per hundred. 1/125 = x/100 which means 125x = 100
which means x = 0.8

An order is written to administer 2 liters of an IV fluid over 18 hours. What
will the flow rate be? - Answer✔️✔️-111 mL/hr



Divide the volume by the time to get the flow rate: 2 liters equals 2,000 mL.
2000/18 = 111.1 mL/hr

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? - Answer✔️✔️-
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 - Answer✔️✔️-12.1 lb
