ORAL AND PARENTERAL DOSAGE

Calculate dosage by using proportions.

1. A patient must take 120 milligrams of medication per day. Each pill contains 30

milligrams of medication. How many pills should the patient take?

2. A patient is to receive 2.6 grams of medication. The medication is available in

capsules of 325 milligrams. How many capsules should be given?

3. A doctor orders 120 milligrams of medication to be given to a patient. If 0.5

milliliters of liquid contains 30 milligrams of medication, how many milliliters should

be given to the patient?

4. A patient must take 200 milligrams of medication with each meal. If 1 milliliter of

liquid contains 25 milligrams of medication, how many milliliters of medication should

the patient take each day? Assume that the patient eats 3 meals per day.

5. A patient must receive an injection of 2.4 grams of medication. If 1 milliliter of

liquid contains 120 milligrams of medication, how many milliliters should be injected

into the patient?

6. A doctor orders an injection of 75 milligrams of medication for a patient. If 3

milliliters of liquid contain 15 milligrams of medication, how many milliliters should be

injected into the patient?

DOSAGE BY WEIGHT

1. A patient weighs 165 pounds. He must receive medication in the amount of 40

mg/kg/day. The medication, which is available in capsules of 150 mg, should be taken in 4

equal doses each day.

a. Convert 165 pounds to kilograms (1 kg = 2.2 lb).

b. Calculate the total number of milligrams the patient must receive each day.

c. Calculate the number of capsules the patient should take in each dose.

2. A patient weighs 132 pounds. She must receive medication in the amount of 70

mg/kg/day. The medication is available in tablets of 350 mg. She must take 3 equal

doses each day.

a. Convert 132 pounds to kilograms (1 kg = 2.2 lb).

b. Calculate the total number of milligrams the patient must receive each day.

c. Calculate the number of capsules the patient should take in each dose.

Medical Math

DRIP RATE

Calculate the drip rate. When needed, round to the nearest tenth.

1. 100 milliliters of medication over 30 minutes using a 15-drip set

2. 750 milliliters of medication over 5 hours using a 10-drip set

3. 250 milliliters of medication over 4 hours using a 12-drip set

4. 1,000 milliliters of medication over 24 hours using a 15-drip set

5. 2,400 milliliters of medication over 24 hours using a 10-drip set
