ATI TEAS Practice Science Test

1. In which position allows access to the stomach?

Correct answer: B

Rationale: The question now specifies the need for a position that allows access to the stomach. The correct answer is 'B: Prone.' In the prone position, the patient lies face down, which facilitates access to the stomach for various procedures or examinations. Choice A, 'Medial,' refers to a direction rather than a patient position. Choice C, 'Superficial,' describes a superficial depth rather than a patient position. Choice D, 'Supine,' is a position where the patient lies face up, which does not provide easy access to the stomach.

2. Which is the correct order of formed elements in blood from smallest to largest cell size?

Correct answer: C

Rationale: The correct order of formed elements in blood from smallest to largest cell size is thrombocytes (platelets), erythrocytes (red blood cells), and leukocytes (white blood cells), making choice C the correct answer. Thrombocytes are the smallest, followed by erythrocytes, and then leukocytes. Choices A, B, and D are incorrect because they do not follow the correct order of cell size in blood formed elements.

3. Which of the following structures in the body is responsible for protecting the lungs and heart?

Correct answer: A

Rationale: The rib cage is the correct answer. It plays a crucial role in protecting vital organs like the lungs and heart. The rib cage forms a protective barrier around these organs, shielding them from external trauma or injuries. It acts as a sturdy cage, offering structural support and safeguarding the delicate tissues and structures of the lungs and heart. The pelvis, femur, and vertebral column do not directly protect the lungs and heart; instead, they have other important functions in the body, such as supporting the body's weight, enabling movement, and protecting the spinal cord.

4. Which of the following immune cells are part of the innate immune response?

Correct answer: C

Rationale: Natural Killer cells are a crucial component of the innate immune response. They play a significant role in defending against infected or cancerous cells through their ability to identify and kill abnormal cells. B-cells (Choice A) and Cytotoxic T-cells (Choice B) are part of the adaptive immune response, which involves a more specific and targeted response to pathogens. Antigen-Presenting Cells (Choice D) are also part of the adaptive immune response, where they present antigens to activate other immune cells.

5. When conducting a research study, which of the following is NOT a good reason for using a computer?

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.
