Questions and Answers
If a physician writes an order for 400 mL of D5W to be infused over a 4-
hour time period, and the IV drop factor is 12 gtt/mL, how many drops per
minute should be delivered?
a. 12 gtt
b. 2 gtt
c. 1.67 gtt
d. 20 gtt - Answer✔️✔️-20 gtt
First find the total number of minutes: 60 X 4 = 240. Then find mL/min: 400
/ 240 = 1.67 ml infused in 1 minute. Then multiply this by the drop factor:
1.67 X 12 = 20 drops per minute.
A drug sells for $29.99 retail and has a wholesale cost of $19.74. The
dispensing cost is $3.20. What is the pharmacy's net profit?
To convert from Fahrenheit to Celsius, subtract 32 from the Fahrenheit
temperature and then divide by 1.8.
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 - 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.
