1. Question 1Ref: ATI TEAS 7 — Math: Numbers and Algebra — M.1.1 Apply arithmetic operations to fractions

   A nurse needs to administer 3/4 of a 60 mL dose of liquid medication. How many milliliters should the nurse administer?

   A50 mLB40 mLC30 mLD45 mL
   Show Answer & Explanation

   Correct Answer
   D. 45 mL

   To find 3/4 of 60 mL, multiply: 3/4 × 60 = 45 mL. This is a basic fraction multiplication problem commonly used in medication dosage calculations in healthcare settings. The other options represent common arithmetic errors: 30 mL is 1/2 of 60, 40 mL is 2/3, and 50 mL is 5/6.

2. Question 2Ref: ATI TEAS 7 — Math: Numbers and Algebra — M.1.3 Solve real-world problems with rational numbers

   A patient's temperature rises from 98.6°F to 102.4°F. What is the increase in temperature in degrees Fahrenheit?

   A3.2°FB4.2°FC2.8°FD3.8°F
   Show Answer & Explanation

   Correct Answer
   D. 3.8°F

   Subtract the initial temperature from the final temperature: 102.4 − 98.6 = 3.8°F. This is a decimal subtraction problem that tests ability to align decimal points correctly. A common error is reversing the subtraction or misplacing the decimal point, which would yield an incorrect result.
