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
D 0.55 lb - CORRECT ANSWER-12.1 lb
A kilogram is equal to 2.2 pounds. 5.5 X 2.2 = 12.1
The percent equivalent of a 1:125 ratio is:
A 12.5%
B 0.8%
C 8.0%
,D 0.08% - CORRECT 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?
A 101 mL/hr
B 56 mL/hr
C 83 mL/hr
D 111 mL/hr - CORRECT 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
Patient is to be given 90 mg dose of naproxen via suspension containing 25 mg of naproxen per
10 mL. How many mL must be administered?
A 28 mL
B 40 mL
C 36 mL
D 32 mL - CORRECT ANSWER-36 mL
How many mL will a patient receive if infused with 125 mL/hr for 7 hrs?
A 625 mL
, B 875 mL
C 312.5 mL
D 437.5 mL - CORRECT ANSWER-875 mL
How many zolpidem tablets each containing 500 mcg can be prepared from 1g of zolpidem?
A 4,000 tablets
B 1,000 tablets
C 5,000 tablets
D 2,000 tablets - CORRECT ANSWER-2,000 tablets
Conversion: 1 g = 1000000 mcg 1 g = 1000000 mcg 1000000 mcg / 500 mcg = 2000 tablets
How many tsp are in 100 ml?
A 100 tsp
B 50 tsp
C 20 tsp
D 10 tsp - CORRECT ANSWER-20 tsp
Conversion: 1 teaspoon (tsp) = 5 mL 100 mL / 5 mL/tsp = 20 tsp
Patient is to be given 70 mg dose of naproxen via suspension containing 25 mg of naproxen per
10 mL. How many mL must be administered?
