CMT - Certified Medication Technician Dosage Calculation and Measurement Questions and Answers

Question 1

A physician orders 0.5 g of a medication for a resident. The medication is available in 250 mg tablets. How many tablets should the Certified Medication Technician (CMT) administer?

Accepted Answer

2 tablets

Answer

First, convert grams (g) to milligrams (mg) since the available dose is in mg. There are 1000 mg in 1 g. Therefore, 0.5 g is equal to 500 mg (0.5 g * 1000 mg/g). Next, use the formula: (Dose ordered / Dose on hand) * Quantity = Amount to administer. (500 mg / 250 mg) * 1 tablet = 2 tablets.

Question 2

A resident is prescribed an oral suspension with a concentration of 125 mg/5 mL. The order is for 250 mg. How many milliliters (mL) should the CMT pour?

Accepted Answer

10 mL

Answer

Using the formula (Desired Dose / Dose on Hand) x Quantity = Amount to administer: (250 mg / 125 mg) x 5 mL = 10 mL. The CMT should administer 10 mL of the suspension to provide the correct 250 mg dose.

Question 3

The order is to administer 15 mL of a liquid medication. Which of the following is an equivalent measurement?

Accepted Answer

1 tablespoon

Answer

In the household system of measurement, 1 tablespoon (T or tbsp) is equivalent to 15 milliliters (mL). One teaspoon (t or tsp) is equivalent to 5 mL.

Question 4

A resident needs 75 mg of a medication. The available stock is a liquid with a strength of 50 mg per 5 mL. How many mL will the CMT administer?

Accepted Answer

7.5 mL

Answer

To solve this, use the ratio and proportion method or the standard formula. (Desired dose / Have on hand) x Quantity. (75 mg / 50 mg) x 5 mL = 1.5 x 5 mL = 7.5 mL.

Question 5

A physician orders a medication to be given at a dose of 3000 mcg. The supply on hand is in milligrams (mg). How many milligrams is the correct dose?

Accepted Answer

3 mg

Answer

To convert micrograms (mcg) to milligrams (mg), you divide by 1000, as there are 1000 mcg in 1 mg. 3000 mcg / 1000 = 3 mg.
