SECTION 1: FRACTIONS (Questions 1-20)
1. A nurse is calculating a medication dose and needs to add the following
fractions: 1/4 + 3/8. What is the correct sum expressed as a fraction in lowest
terms?
• A) 4/12
• B) 5/8
• C) 1/2
• D) 3/4
Answer: B
Rationale: To add fractions, find a common denominator. The least common
denominator for 4 and 8 is 8. Convert 1/4 to 2/8. Then 2/8 + 3/8 = 5/8. This fraction is
already in lowest terms.
2. A physician orders 3/4 of a tablet, but the available tablet is scored into 1/8
increments. How many eighth-pieces should the nurse administer to equal 3/4 of a
tablet?
• A) 4/8
, Page 3 of 71
• B) 6/8
• C) 8/8
• D) 3/8
Answer: B
Rationale: To convert 3/4 to eighths, multiply both numerator and denominator by 2:
3/4 = 6/8. Therefore, the nurse should administer 6 of the 1/8 pieces.
3. A medication order requires the administration of 2/3 of a 15 mL suspension.
How many millilitres should the nurse administer?
• A) 5 mL
• B) 7.5 mL
• C) 10 mL
• D) 12 mL
Answer: C
Rationale: Multiply 2/3 × 15 mL = (2 × 15) ÷ 3 = 30 ÷ 3 = 10 mL.
4. A patient's intake over 8 hours includes 1/2 cup of water, 3/4 cup of juice, and 1/4
cup of broth. What is the total intake in cups expressed as a fraction in lowest
terms?
• A) 1 1/2 cups
• B) 1 1/4 cups
• C) 1 3/4 cups
• D) 2 cups
Answer: A
Rationale: Add the fractions: 1/2 + 3/4 + 1/4 = 2/4 + 3/4 + 1/4 = 6/4 = 3/2 = 1 1/2 cups.
5. A nurse must divide 5/6 of a medication dose equally among 3 patients. What
fraction of the original dose does each patient receive?
• A) 5/18
• B) 15/6
• C) 5/9
• D) 1/3
, Page 4 of 71
Answer: A
Rationale: Divide 5/6 by 3: (5/6) ÷ 3 = 5/6 × 1/3 = 5/18. Each patient receives 5/18 of the
original dose.
6. A medication label indicates that 3/8 of a tablet contains the active ingredient. If
a patient needs 3/4 of the active ingredient, how many tablets should be
administered?
• A) 1 tablet
• B) 1 1/2 tablets
• C) 2 tablets
• D) 2 1/2 tablets
Answer: C
Rationale: Set up the proportion: 3/8 tablet = 3/4 dose. To find tablets needed: (3/4) ÷
(3/8) = 3/4 × 8/3 = 24/12 = 2 tablets.
7. A nurse is calculating the amount of medication remaining in a vial. The vial
originally contained 5/6 of a gram. The nurse administered 1/3 of a gram. How much
remains?
• A) 1/2 g
• B) 2/3 g
• C) 3/4 g
• D) 4/6 g
Answer: A
Rationale: Subtract: 5/6 - 1/3 = 5/6 - 2/6 = 3/6 = 1/2 g.
8. A liquid medication has a concentration of 1/4 mg per mL. How many millilitres
are needed to deliver 3/4 mg?
• A) 1 mL
• B) 2 mL
• C) 3 mL
• D) 4 mL
Answer: C
Rationale: (3/4) ÷ (1/4) = 3/4 × 4/1 = 12/4 = 3 mL.
9. A patient consumes 7/8 of a 240 mL glass of water. How many millilitres were
consumed?
