Exam Overview

The HESI A2 (Health Education Systems, Inc. Admission Assessment) is a standardized entrance exam used by nursing schools across the United States to evaluate prospective students. Administered by Elsevier, this test assesses academic readiness in key subjects like math, reading, vocabulary, grammar, biology, chemistry, and—most critically—anatomy and physiology. A strong performance on the HESI A2 can open doors to competitive nursing programs, from associate degrees to bachelor's degrees and beyond. The exam is your ticket to proving you have the foundational knowledge needed to succeed in a rigorous nursing curriculum.

What's on the Test

The HESI A2 Anatomy and Physiology section is a comprehensive assessment of human body systems and their functions. It typically consists of 25 to 30 multiple-choice questions, with a 25-minute time limit. The test covers essential topics that form the bedrock of nursing practice, from cellular organization to complex system interactions. Below, we break down the key content areas you can expect.

Skeletal System

This domain focuses on the structure and function of bones, joints, and connective tissues. You'll need to know the major bones of the axial and appendicular skeleton, types of joints (e.g., synovial, cartilaginous), and the role of bones in support, protection, and mineral storage. Expect questions on bone remodeling, fractures, and the function of osteoblasts and osteoclasts.

Muscular System

Here, you'll explore the three types of muscle tissue—skeletal, cardiac, and smooth—and their unique characteristics. Topics include muscle contraction mechanisms (sliding filament theory), major muscle groups, and the role of tendons and ligaments. Understanding how muscles produce movement and maintain posture is essential.

Nervous System

This domain covers the central and peripheral nervous systems, including the brain, spinal cord, and neurons. You should be familiar with action potentials, neurotransmitters, and the divisions of the nervous system (somatic vs. autonomic). Questions may touch on sensory pathways, reflex arcs, and the functions of key brain regions like the cerebrum and cerebellum.

Cardiovascular System

The heart, blood vessels, and blood components are the focus here. Master the anatomy of the heart (chambers, valves, major vessels), the cardiac cycle, and blood flow through the pulmonary and systemic circuits. You'll also need to understand blood pressure regulation, common disorders like hypertension, and the composition of blood (RBCs, WBCs, platelets, plasma).

Respiratory System

This section examines the structures responsible for gas exchange: the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs. Key concepts include the mechanics of breathing (inspiration and expiration), oxygen and carbon dioxide transport, and the regulation of respiration by the medulla oblongata. Be ready for questions on lung volumes and capacities.

Digestive System

From the mouth to the anus, this domain covers the organs involved in food breakdown and nutrient absorption. Know the functions of the stomach, small intestine (duodenum, jejunum, ileum), large intestine, and accessory organs like the liver, gallbladder, and pancreas. Topics include enzyme action, peristalsis, and the role of villi in absorption.

Urinary System

The kidneys, ureters, bladder, and urethra are the focus. Understand how the kidneys filter blood, reabsorb essential substances, and produce urine through processes like glomerular filtration, tubular reabsorption, and secretion. Questions may address the role of the nephron, fluid and electrolyte balance, and acid-base regulation.

Endocrine System

This domain covers the glands that secrete hormones, such as the pituitary, thyroid, adrenal, and pancreas. You'll need to understand hormone feedback loops, target tissues, and the effects of major hormones (e.g., insulin, thyroxine, cortisol). Disorders like diabetes and hyperthyroidism are common topics.

Reproductive System

Both male and female reproductive systems are covered. Topics include gametogenesis (spermatogenesis and oogenesis), the menstrual cycle, fertilization, and hormonal regulation. Knowledge of anatomy such as the ovaries, fallopian tubes, uterus, testes, and accessory glands is essential.

Integumentary System

The skin, hair, nails, and sweat glands make up this system. Focus on the layers of the skin (epidermis, dermis, hypodermis), functions like protection and temperature regulation, and the role of melanin and keratin. Wound healing and skin disorders may also appear.

How to Prepare

To excel on the HESI A2 Anatomy and Physiology practice test, start by reviewing a comprehensive A&P textbook or online resource. Focus on understanding how each system works independently and how they interconnect. Use flashcards to memorize key terms, and practice labeling diagrams of the heart, brain, and skeleton. Our free practice test is an excellent diagnostic tool—take it first to identify weak areas, then target those topics with focused study. Combine this with periodic retakes to track your progress. Consistent, spaced repetition is more effective than cramming.

Test Day Tips

On exam day, arrive early with your admission ticket, photo ID, and any allowed materials (check with your school). The HESI A2 is typically computer-based, so be comfortable with basic navigation. Manage your time wisely: you have about one minute per question on the Anatomy and Physiology section. If you get stuck, mark the question and move on, then return if time permits. Stay calm and read each question carefully—look for keywords like "not" or "except." Get a good night's sleep and eat a balanced meal beforehand to maintain focus.

Scoring and Results

The HESI A2 uses a scoring scale from 0 to 100, with most nursing programs requiring a score of 75 or higher in each section. However, some schools set higher thresholds (e.g., 80 or 85) for competitive programs. Your results are typically available immediately after completing the exam, and you can view a detailed breakdown of your performance by subject. Use this feedback to identify strengths and weaknesses for future study or retakes.

Retaking the Exam

If you don't achieve your desired score, you can retake the HESI A2. Policies vary by school, but many allow retakes after 30 to 60 days. Some institutions limit the number of attempts (e.g., three per year). There is usually a fee for each retake, often between $40 and $100. Check with your specific program for exact policies. Our practice test is a valuable tool to prepare for retakes, helping you improve weak areas before your next attempt.
