ATI TEAS Science Practice Test Questions

Question 1 of 5

What is the anatomical term for the back of the body? Example: Shoulder blade.

Correct Answer: C

Rationale: The correct answer is C: Posterior. 'Posterior' is the anatomical term that refers to the back of the body. It is the opposite of 'anterior,' which refers to the front of the body. 'Superior' typically describes a structure that is positioned above another structure, while 'inferior' refers to a structure that is below another. In this case, the term 'posterior' specifically indicates the back of the body, making it the most appropriate choice among the options provided.

Question 2 of 5

Which blood vessels transport blood from the capillaries back to the heart?

Correct Answer: B

Rationale: Veins are the correct answer as they are the blood vessels that carry blood from the capillaries back to the heart. Veins have thinner walls compared to arteries and contain valves to prevent blood from flowing backward. This transport of blood from the capillaries to the heart is essential for the circulatory system to maintain proper blood flow and oxygenation levels. Arterioles are small branches of arteries that lead to capillaries, not vessels that transport blood back to the heart. Venules are small vessels that collect blood from capillaries and lead to veins. Capillaries are the smallest blood vessels where the exchange of gases and nutrients occurs between blood and tissues, not vessels that transport blood back to the heart.

Question 3 of 5

Which of the following accurately describes the measurements?

Correct Answer: B

Rationale: Accuracy refers to how close a measurement is to the true or accepted value, while precision refers to how close individual measurements are to each other. If the measurements are accurate but not precise, it means they consistently hit the target value but may vary in terms of how closely grouped they are. Choice B, 'They are accurate but not precise,' correctly describes the scenario where the measurements are on target but not consistently close to each other. Choice A is incorrect because it implies both accuracy and precision, which is not the case here. Choice C is incorrect because it suggests precision without accuracy, while choice D is incorrect as it indicates neither accuracy nor precision, which is not a typical scenario for measurements.

Question 4 of 5

What is the basic structure of an atom?

Correct Answer: A

Rationale: The basic structure of an atom consists of protons and neutrons located in the nucleus, with electrons orbiting around the nucleus in specific energy levels or shells. Protons carry a positive charge, neutrons carry no charge, and electrons carry a negative charge. This arrangement maintains the overall neutrality of the atom, with the number of protons equaling the number of electrons. Therefore, the correct answer is 'Protons, neutrons, electrons.' Choices B, C, and D are incorrect as they do not accurately represent the fundamental components of an atom. Choice B includes 'ions,' which are charged particles, not fundamental components of an atom. Choice C includes 'ions' and lacks protons. Choice D includes 'ions' and 'molecules,' which are not part of the basic structure of an atom.

Question 5 of 5

Which three parts make up the large intestine?

Correct Answer: B

Rationale: The correct answer is B: Cecum, colon, rectum. The large intestine is composed of the cecum, colon, and rectum. These parts are responsible for water absorption and feces formation. Choices A, C, and D are incorrect. A contains parts of the small intestine (duodenum, ileum, jejunum), C has a mix of small and large intestine parts, and D includes the small intestine part ileum. Understanding the correct anatomy of the large intestine is essential for distinguishing it from the small intestine.
