Free CAOP Pharmaceutical Calculations Questions and Answers

Question 1

27 mg= mcg

Accepted Answer

27,000 mcg

Answer

To convert milligrams (mg) to micrograms (mcg), you multiply the milligram value by 1,000, because 1 milligram is equivalent to 1,000 micrograms. Therefore, 27 mg multiplied by 1,000 mcg/mg equals 27,000 mcg. This is a fundamental unit conversion used in pharmaceutical calculations.

Question 2

6 tsp = ml

Accepted Answer

30 mL

Answer

A standard conversion in pharmacy and medicine is that 1 teaspoon (tsp) is approximately equal to 5 milliliters (mL). To convert 6 teaspoons to milliliters, you multiply 6 tsp by 5 mL/tsp. This calculation yields a total volume of 30 mL.

Question 3

The doctor writes an order for a liquid oral medication. The order says to administer 15 mg by mouth every 4 hours as needed for sore throat. Pharmacy dispenses you with 30 mg/3ml. How many ml will you administer per dose?

Accepted Answer

1.5 mL/dose

Answer

To determine the volume to administer, you can use a simple ratio or dimensional analysis. The order is for 15 mg, and the available concentration is 30 mg in 3 mL. Setting up the proportion (15 mg / x mL) = (30 mg / 3 mL) and solving for x gives (15 mg * 3 mL) / 30 mg = 1.5 mL. Thus, 1.5 mL should be administered per dose.

Question 4

The doctor writes an order a liquid oral medication. The order says to administer 20 grams by mouth BID. Pharmacy dispenses you with 10 gram/15 ml. How many ml will you administer per dose?

Accepted Answer

30 mL/dose

Answer

The doctor ordered 20 grams, and the medication is supplied at a concentration of 10 grams per 15 mL. To calculate the volume needed, divide the desired dose (20 grams) by the concentration (10 grams/15 mL). This results in (20 grams / 10 grams) * 15 mL = 2 * 15 mL, which equals 30 mL per dose.

Question 5

The doctor writes an order for a medication. The order says to administer 12.5 mg PO BID. Pharmacy dispenses you with 6.25 mg tablets. How many tablets do you administer with this dose?

Accepted Answer

2 tablets/dose

Answer

The order specifies 12.5 mg, and the available tablets are 6.25 mg each. To find out how many tablets are needed, divide the ordered dose by the strength per tablet. Performing the calculation 12.5 mg / 6.25 mg/tablet yields 2 tablets. Therefore, 2 tablets should be administered per dose.
