ATI TEAS Science Practice Test
1. Identify the correct sequence of the 3 primary body planes as numbered 1, 2, and 3 in the above image.
- A. Plane 1 is coronal, plane 2 is sagittal, and plane 3 is transverse.
- B. Plane 1 is sagittal, plane 2 is coronal, and plane 3 is medial.
- C. Plane 1 is coronal, plane 2 is sagittal, and plane 3 is medial.
- D. Plane 1 is sagittal, plane 2 is coronal, and plane 3 is transverse.
Correct answer: A
Rationale: In the standard anatomical position, plane 1 (coronal/frontal plane) divides the body into anterior and posterior portions, plane 2 (sagittal plane) divides the body into left and right portions, and plane 3 (transverse/horizontal plane) divides the body into superior and inferior portions. Therefore, the correct sequence is Plane 1 as coronal, Plane 2 as sagittal, and Plane 3 as transverse, which corresponds to Choice A. Choice B is incorrect as it misidentifies the planes. Plane 2 cannot be coronal as it specifically divides the body into left and right portions. Choice C is incorrect as it misidentifies Plane 2 as sagittal when it should be coronal. Choice D is incorrect as it incorrectly designates Plane 2 as coronal when it should be sagittal, leading to an inaccurate sequence of the primary body planes.
2. Which hormone, produced by the adrenal glands, helps regulate the body's response to stress, including increasing blood pressure and suppressing the immune system?
- A. Aldosterone
- B. Epinephrine
- C. Cortisol
- D. Insulin
Correct answer: C
Rationale: Cortisol is the correct answer. It is the hormone produced by the adrenal glands that helps regulate the body's response to stress. Cortisol plays a crucial role in increasing blood pressure and suppressing the immune system during stressful situations. Aldosterone, another hormone from the adrenal glands, primarily regulates salt and water balance in the body, not the stress response. Epinephrine, also known as adrenaline, is produced by the adrenal glands in response to stress, but its effects are more immediate and short-lived compared to cortisol. Insulin, produced by the pancreas, regulates blood sugar levels and is not directly involved in the body's response to stress.
3. Which of the following best describes the statement: 'This flower is dead; someone must have forgotten to water it'?
- A. A classification
- B. An observation
- C. An inference
- D. A collection
Correct answer: C
Rationale: The correct answer is C - 'An inference'. An inference is a conclusion drawn based on evidence and reasoning, not directly observed facts. In this statement, the conclusion that someone must have forgotten to water the flower is inferred from the observed fact that the flower is dead. Choice A - 'A classification' is incorrect because the statement does not categorize or classify the flower in any way. Choice B - 'An observation' is incorrect because it does not involve interpreting or drawing a conclusion from the observed fact. Choice D - 'A collection' is incorrect as it does not relate to the process of drawing a conclusion based on evidence.
4. Which property of matter refers to the amount of space occupied by an object and is measured in cubic units?
- A. Mass
- B. Density
- C. Weight
- D. Volume
Correct answer: D
Rationale: Volume is the property of matter that refers to the amount of space occupied by an object. It is measured in cubic units, such as cubic meters or cubic centimeters. Mass, on the other hand, is the amount of matter in an object, weight is the force of gravity acting on an object, and density is the mass per unit volume of a substance. In this question, the key concept is the space occupied by an object, which directly relates to volume, making it the correct answer. Choices A, B, and C are incorrect as they do not specifically pertain to the amount of space occupied by an object.
5. How can you predict the charge of an ion formed by an element based on its position on the periodic table?
- A. Look for elements with similar atomic weights
- B. Identify the group number, which often indicates the typical ionic charge
- C. Identify the period number to determine the ionic charge
- D. Analyze the element's position within the group
Correct answer: B
Rationale: The group number of an element on the periodic table often indicates the typical ionic charge it will form. Elements in the same group tend to have similar chemical properties, including the tendency to gain or lose electrons to achieve a stable electron configuration. This predictable pattern allows us to anticipate the charge of an ion formed by an element based on its position in the periodic table. Choices A, C, and D are incorrect because predicting the charge of an ion is primarily based on the element's group number, which reflects its valence electrons and typical ionic charge. Atomic weight (Choice A) and period number (Choice C) do not directly correlate with the ionic charge prediction, and analyzing the element's position within the group (Choice D) is less relevant than identifying the group number itself.
