A nurse charts that a patient ate 3/8 of a meal. What is 3/8 written as a percent?
- A.
0.375%
- B.
37.5%
- C.
3.75%
- D.
266.7%
Answer: B.Divide 3 by 8 to get 0.375, then multiply by 100 to get 37.5%. Writing 0.375% forgets to multiply by 100, and 266.7% comes from dividing 8 by 3.

A patient drinks 2 1/3 cups of water in the morning and 1 3/4 cups in the afternoon. How many cups does the patient drink in total?
- A.
- B.
- C.
- D.
Answer: C.With a common denominator of 12, 1/3 + 3/4 = 4/12 + 9/12 = 13/12 = 1 1/12, so 2 + 1 + 1 1/12 = 4 1/12. 3 1/12 drops the whole number carried from 13/12, and 3 4/7 adds numerators and denominators straight across.

A lab reports that 2.4% of a blood sample is a certain protein. What is 2.4% written as a fraction in lowest terms?
- A.
- B.
- C.
- D.
Answer: C.Percent means per 100, so 2.4% = 2.4/100 = 24/1000, and dividing both by 8 gives 3/125. 6/25 is 24%, which comes from dropping the decimal point in 2.4.

A clinic saw an average of 80 patients per day last year and 92 patients per day this year. What is the percent increase?
- A.
12%
- B.
13%
- C.
115%
- D.
15%
Answer: D.Percent change = (new − old) ÷ old = (92 − 80) ÷ 80 = 12 ÷ 80 = 0.15 = 15%. Dividing by the new value (12 ÷ 92 ≈ 13%) or reporting the 12-patient difference as 12% are common errors.

A unit keeps a nurse-to-patient ratio of 2:9. How many nurses are needed for 45 patients?
- A.
5
- B.
10
- C.
38
- D.
202.5
Answer: B.Set up 2/9 = x/45, so 9x = 90 and x = 10 nurses. 5 is only the number of groups of 9 patients, and 38 subtracts the 7-person difference instead of using a proportion.

On a map, 1 inch represents 25 miles. Two towns are 3.5 inches apart on the map. What is the actual distance between them?
- A.
87.5 miles
- B.
28.5 miles
- C.
7.1 miles
- D.
0.14 miles
Answer: A.Multiply the map distance by the scale: 3.5 × 25 = 87.5 miles. 28.5 adds the numbers instead of multiplying, and 7.1 divides 25 by 3.5.

Solve for x in the equation x/4 + 5 = 12:
- A.
x = 1 3/4
- B.
x = 68
- C.
x = 28
- D.
x = 43
Answer: C.Subtract 5 from both sides to get x/4 = 7, then multiply by 4 to get x = 28. x = 1 3/4 divides 7 by 4 instead of multiplying, and x = 68 adds 5 instead of subtracting it.

Five less than twice a number is 31. What is the number?
- A.
18
- B.
13
- C.
20.5
- D.
−13
Answer: A.Twice a number is 2n, and five less than that is 2n − 5, so 2n − 5 = 31, 2n = 36 and n = 18. 13 solves 2n + 5 = 31, and −13 reverses the order as 5 − 2n.

What is (3.2 × 10⁵)(2.5 × 10⁻²) written in scientific notation?
- A.
8.0 × 10³
- B.
8.0 × 10⁻¹⁰
- C.
5.7 × 10³
- D.
8.0 × 10⁷
Answer: A.Multiply the coefficients (3.2 × 2.5 = 8.0) and add the exponents (5 + (−2) = 3) to get 8.0 × 10³. 10⁻¹⁰ multiplies the exponents, and 5.7 adds the coefficients.

A box of 100 exam gloves costs $8.50, and a box of 250 costs $19.75. Which box has the lower cost per glove?
- A.
100-glove box, $0.085 each
- B.
250-glove box, $0.79 each
- C.
100-glove box, $0.0085 each
- D.
250-glove box, $0.079 each
Answer: D.Divide price by count: $8.50 ÷ 100 = $0.085 and $19.75 ÷ 250 = $0.079, so the 250-glove box is cheaper per glove. $0.79 misplaces the decimal point when dividing by 250.
