QUESTION 1
A healthcare provider prescribes 500 mg of a medication. The available
tablets are 250 mg each. How many tablets should the nurse
administer?
A) 1 tablet
B) 1.5 tablets
C) 2 tablets
D) 2.5 tablets
Answer: C) 2 tablets
Explanation: To determine the number of tablets, divide the prescribed
dose by the dose per tablet: 500 mg / 250 mg per tablet = 2 tablets. This
is a basic ratio and proportion calculation fundamental to safe
medication administration.
QUESTION 2

The order reads to administer 0.5 grams of a drug. The pharmacy
supplies the medication in 250 mg capsules. How many capsules are
required?
A) 1 capsule
B) 2 capsules
C) 3 capsules
D) 4 capsules
Answer: B) 2 capsules
Explanation: First, convert grams to milligrams to ensure consistent
units: 0.5 grams = 500 mg. Then divide the prescribed dose by the
available dose: 500 mg / 250 mg per capsule = 2 capsules. Unit
conversion is a critical step in dosage calculations to prevent tenfold
errors.
QUESTION 3
A patient is prescribed 75 mg of meperidine. The vial contains 100 mg
per 2 mL. How many milliliters should the nurse administer?
A) 1 mL
B) 1.5 mL
C) 2 mL
D) 2.5 mL
Answer: B) 1.5 mL
,3|Page
Explanation: Set up the proportion: 100 mg / 2 mL = 75 mg / x mL.
Cross-multiply: 100x = 150, so x = 1.5 mL. This demonstrates the
application of ratio and proportion in parenteral medication dosing.
QUESTION 4
The provider orders 40 mEq of potassium chloride. The available
concentration is 20 mEq per 15 mL. How many milliliters will the nurse
administer?
A) 15 mL
B) 20 mL
C) 30 mL
D) 45 mL
Answer: C) 30 mL
Explanation: The proportion is 20 mEq / 15 mL = 40 mEq / x mL. Cross-
multiply to get 20x = 600, yielding x = 30 mL. Attention to the
concentration and desired dose is essential for electrolyte replacement
therapy.
QUESTION 5
A child weighs 44 pounds. The medication is ordered at 2 mg/kg/day in
divided doses. What is the total daily dose in milligrams?
A) 20 mg
B) 30 mg
, 4|Page
C) 40 mg
D) 88 mg
Answer: C) 40 mg
Explanation: Convert pounds to kilograms: 44 pounds / 2.2 = 20 kg.
Multiply the weight in kg by the dose: 20 kg x 2 mg/kg = 40 mg. Weight-
based dosing is common in pediatric and critical care settings.
QUESTION 6
The nurse needs to infuse 1,000 mL of normal saline over 8 hours. The
drop factor is 15 gtt/mL. Calculate the drip rate in drops per minute.
A) 31 gtt/min
B) 32 gtt/min
C) 33 gtt/min
D) 34 gtt/min
Answer: A) 31 gtt/min
Explanation: First calculate the flow rate in mL/hr: 1000 mL / 8 hr = 125
mL/hr. Convert to mL/min: 125 mL/hr / 60 min/hr = 2.083 mL/min.
Multiply by the drop factor: 2.083 mL/min x 15 gtt/mL = 31.25, rounded
to 31 gtt/min. Precise IV flow rate calculation prevents fluid imbalances.
