PTCB Practice Exam (Math)
If a medical doctor writes an order for four hundred mL of D5W to be infused over a four-hour
term, and the IV drop factor is 12 gtt/mL, what number of drops consistent with minute should
be introduced?
A. 12 gtt
b. 2 gtt
c. 1.67 gtt
d. 20 gtt - ANS20 gtt
First discover the total variety of minutes: 60 X four = 240. Then discover mL/min: =
1.Sixty seven ml infused in 1 minute. Then multiply this with the aid of the drop aspect: 1.Sixty
seven X 12 = 20 drops according to minute.
A drug sells for $29.99 retail and has a wholesale fee of $19.74. The shelling out fee is
$three.20. What is the drugstore's internet earnings?
A $10.25
B $29.99
C $3.20
D $7.05 - ANS$7.05
Gross profit is promoting charge minus purchase fee. For net earnings you also want to subtract
the meting out cost as properly.
You are making plans to prepare six hundred mL of 20% dextrose solution, by mixing your 5%
and 50% dextrose answer. How plenty of each solution could be wished?
A 350 mL of the 50% and 250 mL of the 5%
B 300 mL of the 50% and 100 mL of the five%
C two hundred mL of the 50% and four hundred mL of the 5%
D 300 mL of the 50% and 300 mL of the five% - ANS200 mL of the 50% and four hundred mL of
the 5%
Seventy-four stages Fahrenheit is same to what temperature in Celsius?
A 74.0
B 23.Three
C 18.3
, D 30.7 - ANS23.Three
To convert from Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature after which
divide with the aid of 1.8.
An order is written for 500 mL of NS to infuse at 40 gtt/min. How long wouldn't it take to infuse
the NS if the set grants 10 gtt/mL?
A forty minutes
B a hundred twenty five minutes
C 50 mins
D a hundred mins - ANS125 mins
10 gtt/mL approach 10 drops in line with mL. So for 500 mL you'll get: 10 X 500 = 5,000 drops.
The waft charge is forty gtt/min, this means that 40 drops consistent with minute, so divide
general drops by way of forty to get the wide variety of minutes: 5,000/40 = one hundred twenty
five.
Convert 5.Five kg to kilos.
A 1.21 lb
B 55 lb
C 12.1 lb
D 0.55 lb - ANS12.1 lb
A kilogram is identical to two.2 kilos. Five.5 X 2.2 = 12.1
The percent equal of a 1:125 ratio is:
A 12.Five%
B zero.Eight%
C 8.0%
D zero.08% - ANS0.8%
Percent approach elements according to hundred. 1/a hundred twenty five = x/a hundred
because of this 125x = a hundred this means that x = zero.8
An order is written to administer 2 liters of an IV fluid over 18 hours. What will the float charge
be?
