HESI A2

Vocabulary HESI A2 Practice Test

1. What does Elevate mean?

A. To lower
B. To lift up or place in a higher position
C. To flatten
D. To remove

Correct answer: B

Rationale: The correct answer is B: 'To lift up or place in a higher position.' Elevate means to raise something to a higher level or position. Choice A, 'To lower,' is incorrect as it is the opposite of elevate. Choice C, 'To flatten,' is incorrect as it means to make something level or smooth, not to raise it. Choice D, 'To remove,' is also incorrect as it means to take something away, not to lift or raise it.

2. Which word correctly completes the sentence? 'I ___ the package on the table.'

A. Layed
B. Drop
C. Laid
D. Lay

Correct answer: C

Rationale: The correct answer is 'C: Laid.' 'Laid' is the correct past tense form of 'lay,' which means to put something down. 'Layed' in choice A is incorrect as the past tense of 'lay' is 'laid,' not 'layed.' Choice B, 'Drop,' is incorrect as it does not fit the context of placing something on the table. Choice D, 'Lay,' is the base form of the verb and does not fit the sentence in the past tense.

3. 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.

4. What is the meaning of Hygiene?

A. General cleanliness and good health practices
B. Measures contributing to cleanliness and good health
C. A measure of dietary health
D. A type of infection

Correct answer: B

Rationale: The correct answer is B: 'Measures contributing to cleanliness and good health.' Hygiene encompasses practices that promote cleanliness and overall good health, such as washing hands, maintaining personal hygiene, and keeping the surroundings clean. Choice A has been revised to 'General cleanliness and good health practices' to better reflect the concept of hygiene. Hygiene goes beyond just cleanliness to include specific measures for maintaining health. Choice C is incorrect as hygiene is not specifically related to dietary health; it is more about cleanliness and health practices. Choice D is incorrect as hygiene is not a type of infection; it is about preventing infections through proper practices.

5. A symptom that is exacerbated is ____?

A. Improving
B. Made worse
C. Stayed the same
D. Ameliorated

Correct answer: B

Rationale: The correct answer is 'B) Made worse.' Exacerbated means to make a condition more severe or intense. Therefore, if a symptom is exacerbated, it is getting worse, not improving (choice A), staying the same (choice C), or ameliorated (choice D), which means to improve or make better.
