Sample questions from ATI TEAS Version 7 — Original Latest Version Study Set Study Guide

This material has 20 questions with answers and rationales. Here are the first 5.

1. 1.Which of the following structures is primarily responsible for the production of ATP within a human cell?

   • A.Golgi apparatus
   • B.Ribosomes
   • C.Mitochondria
   • D.Lysosomes

   Rationale: Mitochondria are known as the powerhouses of the cell because they perform aerobic respiration to produce ATP. Ribosomes synthesize proteins, the Golgi apparatus packages proteins, and lysosomes contain digestive enzymes.

2. 2.In the respiratory system, what is the primary function of surfactant in the alveoli?

   • A.To warm and humidify incoming air
   • B.To facilitate the diffusion of oxygen
   • C.To filter out dust and pathogens
   • D.To reduce surface tension and prevent collapse

   Rationale: Surfactant is a lipoprotein that coats the inner surface of the alveoli, reducing surface tension and preventing the air sacs from collapsing during exhalation. Filtration and warming occur in the upper respiratory tract.

3. 3.Which valve prevents the backflow of blood from the right ventricle into the right atrium?

   • A.Tricuspid valve
   • B.Pulmonary valve
   • C.Aortic valve
   • D.Mitral valve

   Rationale: The tricuspid valve is located between the right atrium and right ventricle. The mitral (bicuspid) valve is on the left side. The pulmonary and aortic valves are semilunar valves that prevent backflow from the great vessels into the ventricles.

4. 4.A patient's blood pressure drops, triggering the release of renin. Which organ is responsible for secreting this enzyme?

   • A.Liver
   • B.Kidney
   • C.Adrenal gland
   • D.Pancreas

   Answer and rationale are in the full material.

5. 5.Which part of the brain is primarily responsible for coordinating balance and fine motor movement?

   • A.Medulla oblongata
   • B.Hypothalamus
   • C.Cerebrum
   • D.Cerebellum

   Answer and rationale are in the full material.
