Sample questions from HESI A2 Community Health

This material has 310 questions with answers and rationales. Here are the first 5.

1. 1.**Add: 2 3/4 + 5/6, reduced to lowest terms =**

   • A.3 5/12.
   • B.4 7/12.
   • C.3 7/12.
   • D.4 1/12.

   Rationale: Convert the fractions to twelfths: 3/4 is 9/12 and 5/6 is 10/12, so the sum is 3 + 19/12, or 4 7/12. The first option is one whole too small, and the second incorrectly subtracts part of the fractional sum. The third option has the wrong fractional part; when adding mixed numbers, regroup an improper fractional sum as a whole number.

2. 2.**Change 37.5% to a decimal.**

   • A.0.0375.
   • B.3.75.
   • C.37.5.
   • D.0.375.

   Rationale: Divide a percent by 100 by moving its decimal point two places left, giving 0.375. The first option moves the decimal only one place, while the third moves it three places. The fourth leaves the value as a percent rather than converting it to a decimal.

3. 3.**What is 3/4 of 28?**

   • A.7.
   • B.18.
   • C.21.
   • D.24.

   Rationale: One-fourth of 28 is 7, and three-fourths is 3 x 7, or 21. The first option gives only one-fourth of 28. The other options do not represent three of the four equal parts of 28.

4. 4.**A mixture uses ingredients in a ratio of 2:5. If the total amount is 42 mL, how many milliliters are the first ingredient?**

   • A.12 mL.
   • B.15 mL.
   • C.6 mL.
   • D.30 mL.

   Answer and rationale are in the full material.
