  1. What is 3/8 + 5/12?

    Answer: 19/24

    Find the LCD (24): 3/8 = 9/24, 5/12 = 10/24. Sum: 9/24 + 10/24 = 19/24.

  2. A nurse works 36 hours per week. If she receives a 15% pay increase on her hourly rate of $28, what is her new weekly pay?

    Answer: $1,159.20

    New hourly rate: $28 × 1.15 = $32.20. New weekly pay: $32.20 × 36 = $1,159.20.

  3. Simplify: 4² × 3 - 2(5 + 3)

    Answer: 32

    Following order of operations (PEMDAS): 4² = 16, parentheses: 5+3 = 8, then 16 × 3 = 48, and 2 × 8 = 16. Finally: 48 - 16 = 32.

  4. Convert 2.75 to a fraction in lowest terms.

    Answer: Both A and C

    2.75 = 2 + 0.75 = 2 + 75/100 = 2 + 3/4 = 2 3/4, which equals 11/4 as an improper fraction. Both A and C are correct representations.

  5. If a medication vial costs $12.50 and the hospital uses an average of 8 vials per day, what is the monthly cost for 30 days?

    Answer: $3,000

    Daily cost: $12.50 × 8 = $100. Monthly cost: $100 × 30 = $3,000.

  6. What is the mean of the following patient temperatures: 98.6, 99.2, 100.4, 98.8, 101.0?

    Answer: 99.6°F

    Mean = sum of all values / number of values = (98.6 + 99.2 + 100.4 + 98.8 + 101.0) / 5 = 498.0 / 5 = 99.6°F.
