ATI TEAS 7
ATI TEAS Science Test
1. When conducting a research study, which of the following is NOT a good reason for using a computer?
- A. A computer can be used to store and sort large quantities of data.
- B. Computers can interface with instruments and record data efficiently.
- C. Using a computer eliminates all subjectivity and potential bias from an experiment.
- D. A computer can perform complex calculations more quickly and accurately than a human can.
Correct answer: C
Rationale: Using a computer does not eliminate all subjectivity and potential bias from an experiment. While computers can assist in data collection and analysis, the design and execution of the research study can still be influenced by subjectivity and bias introduced by researchers. Researchers need to recognize their potential biases and take measures to reduce them throughout the research process. Choice A is correct as computers are valuable for managing large datasets. Choice B is correct as computers can efficiently work with instruments and record data. Choice D is correct as computers excel in performing complex calculations faster and more accurately than humans.
2. Where is the scapula in relation to the olecranon?
- A. Distal
- B. Lateral
- C. Ventral
- D. Superior
Correct answer: D
Rationale: The correct answer is D: 'Superior.' The scapula is located superior to the olecranon. In anatomical terms, 'superior' refers to a position above or higher than a reference point. 'Distal' is a term used to describe a position farther away from the point of attachment or origin. 'Lateral' refers to a position further away from the midline of the body. 'Ventral' refers to the front or anterior side of the body. In this case, the scapula being superior to the olecranon means it is positioned above the olecranon bone.
3. Which valve allows blood flow from the right atrium into the right ventricle?
- A. Tricuspid valve
- B. Pulmonic valve
- C. Mitral valve
- D. Aortic valve
Correct answer: A
Rationale: The correct answer is the Tricuspid valve. This valve is located between the right atrium and the right ventricle in the heart. Its primary function is to facilitate the flow of blood from the right atrium into the right ventricle and to prevent the backflow of blood. The Pulmonic valve (choice B) is situated between the right ventricle and the pulmonary artery, not between the right atrium and ventricle, making it incorrect. The Mitral valve (choice C) is found between the left atrium and the left ventricle, not the right side, so it is incorrect. The Aortic valve (choice D) is positioned between the left ventricle and the aorta, not involved in the right atrium and ventricle connection, hence it is also incorrect.
4. Where is the abdominopelvic cavity in relation to the thoracic cavity?
- A. Dorsal
- B. Ventral
- C. Superior
- D. Inferior
Correct answer: D
Rationale: The abdominopelvic cavity is located inferior to the thoracic cavity. The thoracic cavity contains organs like the heart and lungs, while the abdominopelvic cavity includes the abdomen and pelvis regions. Therefore, the correct answer is D, as the abdominopelvic cavity is positioned below (inferior to) the thoracic cavity. Choice A (Dorsal) is incorrect as it refers to the backside of the body. Choice B (Ventral) is incorrect as it refers to the front side of the body. Choice C (Superior) is incorrect as it indicates a position above the thoracic cavity, which is not the case.
5. The adrenal glands are part of the
- A. immune system
- B. endocrine system
- C. lymphatic system
- D. respiratory system
Correct answer: B
Rationale: The correct answer is B: endocrine system. The adrenal glands are part of the endocrine system. These small, triangular-shaped glands are located on top of each kidney and are responsible for producing hormones such as adrenaline, cortisol, and aldosterone. These hormones play a vital role in regulating various body functions, including metabolism, immune response, and stress response. Choices A, C, and D are incorrect because the adrenal glands are not part of the immune system, lymphatic system, or respiratory system. While the immune system is involved in protecting the body from infections and diseases, the lymphatic system helps in maintaining fluid balance and immune function, and the respiratory system is responsible for breathing and gas exchange in the body.
