HESI A2 Vocabulary 2023

1. The breastbone may be called the ___________.

A. stelic
B. steres
C. sterol
D. sternum

Correct answer: D

Rationale: The breastbone is called the sternum. It is a flat bone located in the center of the chest that connects the ribs together and protects the heart and lungs. The term 'stelic' (choice A), 'steres' (choice B), and 'sterol' (choice C) are not correct terminologies for the breastbone.

2. If you are an assiduous worker, you are probably ______.

A. Lazy
B. Industrious
C. Inconsistent
D. Procrastinating

Correct answer: B

Rationale: The correct answer is B, 'Industrious.' Assiduous means showing great care and perseverance in your work, which aligns with being industrious. Choice A, 'Lazy,' is incorrect as it is the opposite of assiduous. Choice C, 'Inconsistent,' does not directly relate to being assiduous, and choice D, 'Procrastinating,' suggests delaying tasks which is contrary to being assiduous.

3. The _____ of this weather was that we all got wet.

A. result
B. effect
C. affect
D. impact

Correct answer: B

Rationale: In this sentence, 'effect' is the correct term to use as it refers to the outcome or consequence of the weather, which was that everyone got wet. 'Effect' is a noun that indicates the result of a particular action or situation. Choice A 'result' is incorrect because it refers to the outcome of an action, not the outcome of weather. Choice C 'affect' is incorrect as it is used as a verb to show influence or make a difference. Choice D 'impact' is incorrect because it refers to a strong influence or effect.

4. What does Debilitating mean?

A. Incapacitating
B. Weakening
C. Empowering
D. Strengthening

Correct answer: A

Rationale: The correct answer is A: 'Incapacitating.' Debilitating means causing incapacity or weakness, making choice A the most appropriate. Choices B, C, and D are incorrect because they represent the opposite of what debilitating means. Weakening (choice B), Empowering (choice C), and Strengthening (choice D) all convey a sense of increasing strength or ability, which is the opposite of the meaning of debilitating.

5. What is Diffusion?

A. Movement of materials from low concentration to high concentration
B. Movement of materials from high concentration to low concentration
C. Absorption of nutrients
D. Breaking of materials

Correct answer: B

Rationale: Diffusion is the process where substances move from an area of high concentration to an area of low concentration. This movement occurs due to the random motion of particles and continues until equilibrium is reached. Choice A is incorrect because diffusion occurs down the concentration gradient, from high to low concentration, not from low to high concentration. Choice C is incorrect as it refers to the uptake of substances by cells, not the general process of diffusion. Choice D is incorrect as it does not accurately describe the process of diffusion; diffusion involves the movement of substances, not the breaking of materials.
