1. 1.

   A provider orders 375 mg of amoxicillin. The suspension contains 125 mg per 5 mL. How many milliliters should be given?

   • A.

     3 mL

   • B.

     75 mL

   • C.

     1.7 mL

   • D.

     15 mL

   Answer: D.

   Use desired ÷ have × volume: 375 ÷ 125 × 5 = 3 × 5 = 15 mL. 3 mL forgets to multiply by the 5 mL volume, and 1.7 mL inverts the ratio (125 × 5 ÷ 375).

2. 2.

   A bar graph shows program enrollment: nursing 120, radiology 45, respiratory therapy 35 and pharmacy technician 50 students. What percent of all students are in radiology?

   • A.

     37.5%

   • B.

     18%

   • C.

     22%

   • D.

     45%

   Answer: B.

   The total is 120 + 45 + 35 + 50 = 250 students, and 45 ÷ 250 = 0.18 = 18%. 37.5% compares radiology with nursing only (45 ÷ 120), and 22% leaves radiology out of the total (45 ÷ 205).

3. 3.

   A line graph shows a patient's temperature: 98.6°F at 08:00, 100.4°F at 12:00, 101.8°F at 16:00 and 99.5°F at 20:00. What was the average rate of change from 08:00 to 16:00?

   • A.

     0.4°F per hour

   • B.

     0.8°F per hour

   • C.

     3.2°F per hour

   • D.

     0.2°F per hour

   Answer: A.

   The temperature rose 101.8 − 98.6 = 3.2°F over 16 − 8 = 8 hours, and 3.2 ÷ 8 = 0.4°F per hour. 0.8 divides by the 4 readings instead of the 8 hours, and 3.2 is the total change, not a rate.

4. 4.

   A nurse records the number of call-light requests on six shifts: 14, 9, 25, 17, 11 and 20. What is the median?

   • A.

     16

   • B.

     21

   • C.

     15.5

   • D.

     14

   Answer: C.

   Order the values first: 9, 11, 14, 17, 20, 25; with an even count, the median is the mean of the middle two, (14 + 17) ÷ 2 = 15.5. 21 averages the middle two values of the unsorted list (25 and 17), and 16 is the mean.

5. 5.

   A student's first four exam scores are 78, 85, 92 and 80. What score on the fifth exam would make the mean of all five exams 85?

   • A.

     85

   • B.

     86.25

   • C.

     90

   • D.

     83.75

   Answer: C.

   A mean of 85 over 5 exams requires a total of 85 × 5 = 425; the first four total 335, so the fifth score must be 425 − 335 = 90. 85 assumes the new score only needs to equal the target mean, and 83.75 is just the current mean of four scores.

6. 6.

   A patient weighs 154 lb. Using 1 kg = 2.2 lb, what is the patient's weight in kilograms?

   • A.

     338.8 kg

   • B.

     70 kg

   • C.

     7 kg

   • D.

     151.8 kg

   Answer: B.

   Kilograms are the larger unit, so divide: 154 ÷ 2.2 = 70 kg. 338.8 kg multiplies by 2.2, giving a number larger than the weight in pounds, which cannot be right.

7. 7.

   A patient is 5 feet 6 inches tall. Using 1 ft = 12 in and 1 in = 2.54 cm, what is the patient's height in centimeters?

   • A.

     142.24 cm

   • B.

     167.64 cm

   • C.

     25.98 cm

   • D.

     170.69 cm

   Answer: B.

   First convert to inches: 5 × 12 + 6 = 66 in, then 66 × 2.54 = 167.64 cm. 142.24 cm treats 5 ft 6 in as 56 inches, and 25.98 cm divides by 2.54 instead of multiplying.

8. 8.

   A sterilizer reservoir holds 15 L of distilled water. Using 1 L = 1.057 qt and 1 gal = 4 qt, about how many gallons does it hold?

   • A.

     15.86 gal

   • B.

     3.55 gal

   • C.

     3.96 gal

   • D.

     63.42 gal

   Answer: C.

   15 × 1.057 = 15.855 qt, and 15.855 ÷ 4 ≈ 3.96 gal. 15.86 stops at quarts, and 63.42 multiplies by 4 instead of dividing.

9. 9.

   A patient room measures 14 feet by 11.5 feet. How many square feet of flooring are needed to cover the floor?

   • A.

     51 sq ft

   • B.

     25.5 sq ft

   • C.

     80.5 sq ft

   • D.

     161 sq ft

   Answer: D.

   Area of a rectangle is length × width: 14 × 11.5 = 161 square feet. 51 is the perimeter (2 × 14 + 2 × 11.5), which measures distance around the room, not floor surface.

10. 10.

    A wheelchair wheel has a diameter of 24 inches. Using π = 3.14, what is the circumference of the wheel?

    • A.

      37.68 in

    • B.

      150.72 in

    • C.

      75.36 in

    • D.

      452.16 in

    Answer: C.

    Circumference = π × diameter = 3.14 × 24 = 75.36 in. 150.72 uses 2π with the diameter instead of the radius, and 452.16 is the area formula πr².
