TOPIC 1: DOSAGE CALCULATIONS
9 Questions • 36.0% of Exam • This topic tests the ability to calculate correct medication dosages based on provided information.
QUESTION 1
A nurse is preparing to administer eszopiclone 2,000 mcg PO to a client. How many
should the nurse administer?
Answer: 2 Mg.
Rationale: The key is to recognize that mcg (micrograms) is a smaller unit of measurement than mg (milligrams), with 1 mg
being equal to 1,000 mcg. Therefore, to convert 2,000 mcg to mg, the nurse would divide by 1,000, resulting in 2 mg, which
is the correct dose to administer.
QUESTION 2
A nurse is preparing to administer codeine 20 mL oral solution to a client. How many
tsp should the nurse administer?
Answer: 4 Tsp.
Rationale: The key to solving this problem is to recognize that the dosage is given in milliliters (mL), but the desired unit of
measurement is teaspoons (tsp), and 1 teaspoon is equivalent to 5 milliliters. Therefore, to find the correct dosage in
teaspoons, the nurse must divide the given dosage in milliliters (20 mL) by the conversion factor (5 mL/tsp), resulting in 4
teaspoons.
QUESTION 3
A nurse is preparing to administer furosemide 20 mg IM. Available is furosemide
injection 10 mg/mL. How many mL should the nurse admsinister?
Answer: 2 ML.
Rationale: The nurse needs to administer 20 mg of furosemide, and since the available injection contains 10 mg per mL,
the nurse must administer 2 mL to deliver the required 20 mg dose. This is calculated by dividing the desired dose (20
mg) by the concentration of the injection (10 mg/mL), resulting in the correct volume of 2 mL.
