ATI TEAS Science Questions

1. What term describes the front of the body, for example, the kneecap?

Correct answer: B

Rationale: The correct answer is 'B: Anterior.' In anatomy, 'anterior' refers to the front of the body, like the kneecap. On the other hand, 'posterior' describes the back of the body. Choices 'C: Superior' and 'D: Inferior' relate to structures being above or below a reference point, respectively, and are not used to describe the front or back of the body. Therefore, 'Anterior' is the most appropriate term given the context provided in the question.

2. Which type of reaction undergoes hydrolysis?

Correct answer: B

Rationale: The correct answer is 'Catabolism.' Catabolic reactions involve the breakdown of larger molecules into smaller ones, often through hydrolysis, where water is added to break chemical bonds. This process is essential for the degradation of complex molecules and the release of energy stored in chemical bonds. Choice A, 'Anabolism,' is incorrect as anabolism involves the synthesis of complex molecules from simpler ones. Choices C and D, 'Exothermic' and 'Endothermic,' refer to the heat energy exchange during a reaction and are not directly related to the process of hydrolysis.

3. Which test is commonly used to assess kidney function?

Correct answer: D

Rationale: The creatinine clearance test is commonly used to assess kidney function. Creatinine, a waste product produced by muscles, is filtered out of the blood by the kidneys. The creatinine clearance test measures how efficiently the kidneys clear creatinine from the blood. Abnormal levels of creatinine in the blood can indicate kidney dysfunction, making this test crucial for evaluating kidney function. Choice A, a complete blood count (CBC), provides information about different blood cells and is not a specific test for kidney function. Choice B, a blood sugar test, assesses glucose levels in the blood and is not directly related to kidney function. Choice C, a urinalysis, evaluates the contents of urine and can provide information about kidney health but is not as specific for assessing kidney function as the creatinine clearance test.

4. Which of the following best describes the function of synergists?

Correct answer: D

Rationale: Synergists play multiple roles in muscle function. They assist primary movers in completing specific movements by working together with them. Additionally, synergists help stabilize the point of origin and provide extra pull near the insertion, contributing to the efficiency of movement. Furthermore, they also help prevent unwanted movement at a joint by ensuring that the intended motion is executed smoothly. Therefore, all the statements in the answer choices accurately describe the functions of synergists, making 'All of the above' the most comprehensive and precise description of their role.

5. Which of the following factors does NOT affect the rate of dissolution of a solute in a solvent?

Correct answer: B

Rationale: Pressure does not affect the rate of dissolution of a solute in a solvent. The factors that affect the rate of dissolution include temperature, surface area, and particle size. Temperature generally increases the rate of dissolution by providing more energy for the solute particles to break apart and mix with the solvent. Increasing the surface area of the solute by grinding it into smaller particles or increasing its contact area with the solvent can also speed up dissolution. Similarly, reducing the particle size of the solute can increase the rate of dissolution by providing more surface area for interaction with the solvent. Pressure, however, does not have a significant impact on the dissolution process and is not a factor that influences the rate at which a solute dissolves in a solvent.
