Questions
1. A nurse needs to administer 750 mg of a medication. The available tablets are
250 mg each. How many tablets should be given?
a) 2
b) 3
c) 4
d) 5
Correct Answer: b)
Rationale: Divide the required dose by the tablet strength: 750 ÷ 250 = 3.
Thus, 3 tablets are needed.
2. Convert 0.625 to a fraction in simplest form.
a) 58
b) 35
c) 21
d) 107
Correct Answer: a)
Rationale: Write 0.625 as 1000
625
. Simplify by dividing numerator and denomi-
nator by their greatest common divisor (125): 1000÷125
625÷125
= 58 .
3. A patient drinks 8 ounces of water every 2 hours. How many ounces will the
patient drink in 12 hours?
a) 24 ounces
b) 32 ounces
c) 48 ounces
d) 64 ounces
Correct Answer: c)
Rationale: Calculate the number of 2-hour periods in 12 hours: 12 ÷ 2 = 6.
Multiply by ounces per period: 6 × 8 = 48.
4. What is 15% of 240?
a) 24
1
, b) 30
c) 36
d) 40
Correct Answer: c)
Rationale: Convert 15% to a decimal: 0.15. Multiply: 0.15 × 240 = 36.
5. Solve for x: 3x + 7 = 22.
a) 5
b) 6
c) 7
d) 8
Correct Answer: a)
Rationale: Subtract 7: 3x = 22 − 7 = 15. Divide by 3: x = 15 ÷ 3 = 5.
6. A recipe requires 43 cup of sugar for 6 servings. How much sugar is needed
for 8 servings?
a) 12 cup
b) 23 cup
c) 1 cup
d) 43 cup
Correct Answer: c)
3
Rationale: Set up a proportion: 64 = x8 . Cross-multiply: 34 × 8 = 6x. Simplify:
3×8
4
= 6. Solve: x = 66 = 1.
7. Convert 2.5 liters to milliliters.
a) 250 mL
b) 2500 mL
c) 25 mL
d) 25000 mL
Correct Answer: b)
Rationale: 1 liter = 1000 milliliters. Multiply: 2.5 × 1000 = 2500.
8. A medication is diluted in a ratio of 1:4. If 20 mL of medication is used, how
much diluent is needed?
a) 40 mL
b) 60 mL
c) 80 mL
d) 100 mL
Correct Answer: c)
Rationale: A 1:4 ratio means 1 part medication to 4 parts diluent. Multiply
medication volume by 4: 20 × 4 = 80.
