HESI A2 Vocabulary Quiz

1. The jawbone may be called the ___________.

A. mantis
B. mantua
C. mandible
D. manganite

Correct answer: C

Rationale: The jawbone is commonly referred to as the mandible in anatomy. It is the largest and strongest bone in the human face and forms the lower jaw, holding the lower teeth in place. "Mandible" is the correct anatomical term for this specific bone structure.

2. Choose the meaning of the word 'exposure' in the following sentence: 'People with weakened immune systems should avoid exposure to flu.'

A. Disclosure
B. Pretense
C. Contact
D. Display

Correct answer: C

Rationale: In this sentence, the word 'exposure' is used to refer to coming in contact with the flu virus. Therefore, in this context, the meaning of 'exposure' is related to 'contact.' Choices A, B, and D are incorrect. 'Disclosure' means revealing information, 'pretense' means pretending, and 'display' means to show or exhibit, none of which captures the intended meaning of 'exposure' in the sentence provided.

3. What does Audible mean?

A. Impossible to hear
B. Able to be heard
C. Visible
D. Silent

Correct answer: B

Rationale: The correct answer is B: 'Able to be heard.' Audible refers to something that can be heard. Choice A, 'Impossible to hear,' is the opposite of the meaning of audible. Choice C, 'Visible,' is unrelated as it pertains to sight, not hearing. Choice D, 'Silent,' is also not correct as it refers to the absence of sound, which is different from something being able to be heard.

4. 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.

5. A condition that is ongoing is ___________.

A. rapid
B. continuous
C. partial
D. complete

Correct answer: B

Rationale: A condition that is ongoing implies that it is happening or existing continuously without interruption. Therefore, the most suitable word to describe such a state is 'continuous.' Choice A, 'rapid,' means fast or quick, which does not convey the idea of ongoingness. Choice C, 'partial,' means incomplete or fragmentary, which is the opposite of ongoing. Choice D, 'complete,' means finished or whole, which also does not align with the concept of ongoing.
