ATI TEAS Science Sample Question & Answer

An example of the question and answer format you may find in the ATI TEAS Math & Science Pack and/or on ATI testing’s actual TEAS exam is set out below.

Topic: Human Anatomy & Physiology

Which of the following diseases is caused by vitamin C deficiency?

  1. Rickets
  2. Beriberi
  3. Scurvy
  4. Anemia

The correct answer is (C).

Scurvy is the disease caused by vitamin C deficiency. Vitamin C is found in fresh fruit and vegetables. Therefore, scurvy used to be highly prevalent in sailors, whose diets lacked fresh produce. Vitamin C plays a key role in the formation of collagen, a protein found in connective tissue. A deficiency of vitamin C is characterized by lethargy, gum disease, edema, and more. This deficiency can be cured by consuming citrus fruits or other vitamin-C-rich foods.

Rickets is a disease caused by vitamin D deficiency. Vitamin D is synthesized in the human body upon exposure to sunlight. Therefore, Rickets was highly prevalent during the Industrial Revolution in Europe, where children worked in factories and were exposed to very little sunlight while growing up.

Beriberi is a disease caused by vitamin B1 deficiency. Since Vitamin B1 is abundant in whole rice, meat, and legumes, Beriberi is prevalent is certain areas in Asia where the diet is composed primarily of white rice.

Anemia is a disease caused by a red blood cell (RBC) deficiency or by a hemoglobin deficiency. Such deficiencies can be the result of malnutrition, infections, genetic diseases, and more.

What Is the ATI TEAS Science Test?

The ATI Nursing Science Test is one of the most difficult sections for many test takers. As one of the largest topic areas, with a lot of material to cover, mastering the Science section requires patience and perseverance.

The ATI TEAS Science Test is a section within the exam focused on three science topics. Of all the sections of the ATI TEAS exam, Science is one of the largest, worth 31% of the exam.

The section is comprised of 53 questions to be answered in just over an hour (63 minutes). The ATI TEAS Science section is comprised of three topics:

  • Human Anatomy & Physiology, (32 items, 68% of the Science section)
  • Life & Physical Sciences, (8 items, 17% of the Science section)
  • Scientific Reasoning, (7 items, 15% of the Science section)
  • An additional 6 items are included as pretest items


The Science section can be the most daunting part of the TEAS Test for many applicants. Use our Step-by-Step mode to learn the complex subject matter, and Timed Mode to improve your performance under time pressure.

TEAS V Earth Science and ATI TEAS Science Topics

ATI Testing's newest ATI TEAS exam features fewer questions on Earth Science as the Earth Science topic has been removed, with some questions absorbed into the remaining topics. Our updated practice tests have been written to reflect these changes. Use all TEAS V practice test and study material with caution; it is likely that they do not offer questions that cover the relevant material on the ATI TEAS test. Use our updated ATI TEAS practice tests to gauge your understanding and improve your TEAS score.
