1. Solve for \(x\): \(3x - 7 = 14\)
A) \(5\)
B) \(6\)
C) \(7\)
D) \(8\)
Answer: C) 7
Rationale: Add 7 to both sides of the equation to
get \(3x = 21\). Divide both sides by 3 to isolate
the variable, which yields \(x = 7\).
2. A patient must receive 1.5 grams of a
medication. The hospital pharmacy stocks 500
mg tablets. How many tablets should the nurse
administer?
A) 2 tablets
, B) 3 tablets
C) 4 tablets
D) 5 tablets
Answer: B) 3 tablets
Rationale: First, convert grams to milligrams by
multiplying by 1,000 (1.5 g × 1,000 = 1,500 mg).
Then, divide the total required dose by the tablet
strength (1,500 mg ÷ 500 mg = 3 tablets).
3. What is 45% of 180?
A) 72
B) 81
C) 90
D) 99
Answer: B) 81
Rationale: Convert the percentage to a decimal
(0.45) and multiply by the total value (\(0.45
\times 180 = 81\)).
4. Add the fractions: \(\frac{2}{3} + \frac{1}{4}\)
A) \(\frac{3}{7}\)
B) \(\frac{11}{12}\)
C) \(\frac{5}{12}\)
D) \(\frac{3}{12}\)
*Answer: B) \(\frac{11}{12}*\)
Rationale: Find the least common denominator,
, which is 12. Convert the fractions: \(\frac{2}{3} =
\frac{8}{12}\) and \(\frac{1}{4} = \frac{3}{12}\).
Add the numerators together to get
\(\frac{11}{12}\).
5. A ratio of 4:5 is equivalent to what percentage?
A) 45%
B) 54%
C) 80%
D) 125%
Answer: C) 80%
Rationale: Express the ratio as a fraction
(\(\frac{4}{5}\)). Divide the numerator by the
denominator to get a decimal (0.80), then
multiply by 100 to get 80%.
6. Solve the proportion: \(\frac{x}{12} =
\frac{5}{6}\)
A) 8
B) 10
C) 15
D) 20
Answer: B) 10
Rationale: Use cross-multiplication to solve the
proportion: \(6x = 12 \times 5\), which simplifies
, to \(6x = 60\). Dividing both sides by 6 yields \(x
= 10\).
7. Convert 2.5 liters to milliliters.
A) 25 mL
B) 250 mL
C) 2,500 mL
D) 25,000 mL
Answer: C) 2,500 mL
Rationale: There are 1,000 milliliters in 1 liter.
Multiply 2.5 by 1,000 to convert the
measurement to 2,500 mL.
