In terms of subject focus, what does the chemistry section test on in the HESI A2?

The chemistry section of the HESI Admission Assessment focuses on basic principles of chemistry that are relevant to nursing. This includes foundational concepts that directly apply to the healthcare field, such as the properties of matter, chemical reactions, stoichiometry, and the understanding of acids and bases. These topics are essential for a nursing student, as they form the groundwork needed for pharmacology, understanding how medications interact in the body, and recognizing the chemical basis of bodily functions.

Other areas, such as organic chemistry concepts, advanced chemical reactions, or environmental chemistry, may not be directly applicable to the nursing curriculum in the same way. While some aspects of organic chemistry might be encountered in nursing studies, the primary focus is not exhaustive or advanced in this section. It aims to ensure that students understand the essential concepts that will aid them in their nursing education and practice.
