A starting point for your school’s module list.
See which concepts need another look across seven review areas. Your school chooses the required HESI A2 modules, so use this short report alongside its current subject and score requirements.
Use the missed-concept list to choose one practical next step. Small samples are sensitive to individual questions; keep practicing with fresh material for a broader picture.

These questions are selected from our HESI A2 bank. Work through proportions, body systems, passage evidence, vocabulary, grammar, biology, and chemistry. Read an explanation for every option.
Independent practice, not an official Elsevier assessment. This sample gives extra space to A&P and math and does not mirror every school’s required modules or test weighting. Twenty questions cannot predict admission or a full HESI result.

- Renal hormone regulation
A patient has a severe drop in renal perfusion pressure. In the renin-angiotensin-aldosterone system, which change most directly increases sodium reabsorption in the distal nephron to help restore blood volume?
- Volume conversion with fractions
A container holds 1.5 L of saline. You pour out 250 mL, then add 3/4 L of sterile water. How much liquid is in the container now (in mL)?
- Finding a passage’s main idea
Which statement best expresses the main idea of the passage?
- Vocabulary in context: succinct
During the meeting, the professor offered a "succinct" explanation of the assignment so students could start right away. What does the word in quotes mean?
- Punctuating an appositive
Which sentence uses commas correctly with an appositive (renaming phrase)?
- Haploid and diploid cells
Which statement best explains why human gametes (egg and sperm) contain 23 chromosomes instead of 46?
- Isotopes and atomic structure
A student compares two atoms of chlorine: chlorine-35 and chlorine-37. Both are neutral atoms. Which statement correctly describes how these two atoms differ?
- Calcium-regulating hormones
A student is contrasting calcitonin and parathyroid hormone (PTH) in calcium homeostasis. Which statement best distinguishes calcitonin from PTH?
- Calculating elapsed time
A clinic asks a patient to arrive at 13:40. Check-in takes 25 minutes, the procedure lasts 1 hour 15 minutes, and recovery takes 50 minutes. If each step begins immediately after the previous one ends, what time (military time) should the patient expect to be ready to leave?
- Lung volumes and capacities
A patient exhales as forcefully as possible after taking the deepest breath possible. Which lung volume is being measured?
- Recognizing the author’s tone
What is the author’s tone in this passage?
- Percentages and whole-number quantities

- Avoiding double negatives
Which sentence avoids a double negative?

- Predicting genetic outcomes
In a simple genetic cross, a plant with genotype Aa is crossed with another plant that is also Aa. Which statement best describes the possible offspring genotypes?
- Ion formation
Which change occurs when a neutral atom becomes a typical ion (such as Na becoming Na+ or Cl becoming Cl-)?
- Solving a proportion
Solve the proportion X:72::35:56. What is the value of X?
- Tracing cardiac blood flow
A nurse is tracing blood flow for a patient with mitral stenosis. Which sequence correctly describes blood flow from the right atrium to the left ventricle, including the correct valves and vessels?
- Mixture ratios and metric units
