Section 1: Basic Conversions & Ratios
Q1: A patient weighs 154 pounds. What is the patient's weight in kilograms?
A. 70 kg [CORRECT]
B. 77 kg
C. 68 kg
D. 84 kg
Correct Answer: A
Rationale: That's right because when you convert pounds to kilograms, you divide by
2.2—so 154 divided by 2.2 equals exactly 70 kg. On the HESI dosage calculation exam,
remember that weight conversions are foundational for nearly every pediatric and adult
medication calculation, so always double-check your division.
Q2: The provider orders 0.5 grams of a medication. The pharmacy supplies tablets that
are 250 mg each. How many tablets will the nurse administer?
A. 0.5 tablets
B. 1 tablet
C. 2 tablets [CORRECT]
D. 4 tablets
,Correct Answer: C
Rationale: The correct formula setup is converting grams to milligrams first—0.5 grams
equals 500 mg—then dividing the desired dose by what you have: 500 mg divided by
250 mg per tablet gives you 2 tablets. Always convert to the same units before
calculating, or you'll end up with the wrong answer.
Q3: A medication is ordered as 150 mcg. The available tablets are 0.3 mg each. How
many tablets should the nurse give?
A. 0.5 tablets [CORRECT]
B. 1 tablet
C. 2 tablets
D. 5 tablets
Correct Answer: A
Rationale: That's right because you need to convert 0.3 mg to micrograms first—multiply
by 1000 to get 300 mcg per tablet—then divide your desired dose of 150 mcg by 300
mcg per tablet, which equals 0.5 tablet. On the HESI exam, watch for those microgram
to milligram conversions; they're tricky and easy to miss if you rush.
Q4: The patient is to receive 2 tablespoons of an elixir. How many milliliters is this
equivalent to?
A. 15 mL
B. 30 mL [CORRECT]
, C. 45 mL
D. 60 mL
Correct Answer: B
Rationale: That's right because 1 tablespoon equals 15 mL, so 2 tablespoons equals 30
mL. This is a standard household to metric conversion you'll see on the
HESI—memorize that 1 tsp = 5 mL, 1 Tbsp = 15 mL, and 1 oz = 30 mL to move quickly
through these problems.
Q5: A provider orders gr 1/150 of a medication. The available tablets are 0.4 mg each.
How many tablets should the nurse administer?
A. 0.5 tablet
B. 1 tablet [CORRECT]
C. 2 tablets
D. 4 tablets
Correct Answer: B
Rationale: The correct formula setup is converting grains to milligrams first—gr 1/150 is
approximately 0.4 mg (since gr 1/150 = 60 mg/150 = 0.4 mg)—so one 0.4 mg tablet is
exactly what you need. Remember that gr 1 = 60 mg is your conversion factor for
apothecary measurements, though these are less common in modern practice.
Q6: The nurse needs to administer 0.125 mg of a medication. The available liquid is 250
mcg per 5 mL. How many mL should the nurse give?
