Drug Calculation Test 1
Name
1. A patient is to receive 600 milliliters of IV over 8 hours. Given that
the tubing has a drop factor of 15 gtt/ml, find the drip rate in gtt/min.
2. A patient weighing 170 pounds is to receive a heparin bolus. The
hospital’s protocol for a heparin bolus is 80 units per kilogram of patient
weight. You have heparin with a strength of 10,000 units per milliliter.
How many milliliters should you administer?
3. A patient is to receive 720 milliliters of IV over 6 hours, with a drop
factor of 12 gtt/ml. After four hours, there are 310 mililiters left in the IV.
Calculate the original drip rate, the modified drip rate, and the percentage
change between the two.
4. A patient is to receive 1.4 grams of medication. The medication is
available in doses of 350 milligrams per milliliter. How many milliliters
should you give?
5. A patient is to receive 75 milligrams of medication. The medication
comes in tablets with each tablet having 25 milligrams of medication. How
many tablets should you give?
6. You have an order for Dobutamine 400mg in 250 mL D5W to infuse
at 10 mcg/kg/min for a client who weighs 75 kg. How many milliliters per
hour should you give?
7. The usual dosage of Velosef is 50 to 100 mg/kg/day in equal doses
four times a day. What is the daily dosage range for a child wieghing 19
kg? What is the the single dosage range for this child?
8. You have an order for 3.75 mg of a medication which is available in 5
mg per milliliter. How many milliliters should you administer?
9. You have an order for 35 mg of Protamine sulfate to be given intravenously. The label reads “10mg / mL”. How many milliliters should you
administer?
10. You are ordered to give a patient 1500 mg of a medication intravenously over three hours. The medication is available in 4 mg per milliliter.
The available tubing has a drop factor of 12 gtt/mL. What should you set as
the drop rate?
11. We have the following sliding scale for insulin orders with respect to
patient finger-stick reading in mg/dL (milligrams per deciliter):
1
2
0-180 mg/dL
181-240 mg/dL
241-300 mg/dL
301-400 mg/dL
Greater than 400 mg/dL
no coverage
2 units
4 units
6 units
8 units and notify doctor.
How much should you give if the reading is 262 mg/dL?
12. You are to infuse heparin intravenously at 900 units/hr from a solution
of 400 mL containing 25,000 units of heparin. Calculate the infusion rate
in milliliters per hour.
13. How many milligrams is 23,400 micrograms?
14. You are to give a patient 25 mg of a drug that is 15 mg per 4 mL.
How many milliliters should you administer?
15. You start a patient on an IV giving 900 mL over 5 hours with a drop
factor of 20 gtt/mL. After two hours, there is 600 mL of fluid remaining.
Recalculate the flow rate and find the percentage change from the original
rate. Is this change within 25%?
16. A child weighs 16 kg and is 54 cm tall. Calculate the child’s BSA.
An adult dose (based on BSA) of a drug is 12 mg. Calculate the child’s
dose.
17. You are to administer 8 mEq of potassium chloride. It comes in a
strength of 2 mEq/mL. How many milliliters should you give?
18. You are to give a 6 mg of a drug that comes in a strength of 5 mg per
2 mL. How much of the drug should you administer?
19. How much dextrose is in 540 mL of 5DW?
20. Nipride has been ordered to titrate at a rate of 4 to 7 mcg/kg/min for
a patient weighing 72 kg. The solution contains 60 mg of Nipride in 200
mL of solution. Calculate the upper and lower rates of infusion in mL/hr.
