HESI A2 Vocabulary Practice Test

1. What does the word Quarantine mean?

A. Isolation
B. Confinement away from the general population
C. Treatment
D. Exposure

Correct answer: B

Rationale: The correct answer is B: 'Confinement away from the general population.' Quarantine is the practice of isolating individuals who may have been exposed to a contagious disease but are not yet ill. This isolation helps prevent the potential spread of the disease. Choice A, 'Isolation,' is partially correct but does not capture the specific aspect of separation from the general population. Choice C, 'Treatment,' is incorrect as quarantine does not involve providing medical care but rather focusing on preventing transmission. Choice D, 'Exposure,' is also incorrect as quarantine is about separating potentially exposed individuals, not intentionally exposing them.

2. After the policeman _____ for several miles, he finally caught up with the man who had stolen the purse.

A. ran
B. had run
C. chased
D. drove

Correct answer: B

Rationale: In this sentence, the correct option is 'had run' as it is the past perfect tense, which is used to indicate an action completed before another past action. The sentence structure requires the past perfect form to show that the running occurred before catching up with the man. 'Ran' (choice A) is in simple past tense and does not convey the sequence of events correctly. 'Chased' (choice C) is the simple past tense of the verb 'chase' and does not align with the past perfect tense needed in the sentence. 'Drove' (choice D) is incorrect as it refers to using a vehicle to pursue someone, whereas the context of the sentence indicates running on foot.

3. The plastic surgery improved the _______ of her face.

A. Bearing
B. Serenity
C. Contour
D. Cataract

Correct answer: C

Rationale: The correct answer is 'Contour.' In the context of the sentence, 'contour' refers to the shape or outline of her face, which is typically altered or enhanced through plastic surgery. 'Bearing' refers to behavior or posture, not the physical appearance of the face. 'Serenity' means calmness and peacefulness, which is not relevant in the context of plastic surgery improving the appearance of the face. 'Cataract' is a medical condition affecting the eye and is completely unrelated to the context of plastic surgery improving facial appearance.

4. The abbreviation PDR refers to a ___________.

A. drug
B. procedure
C. book
D. muscle group

Correct answer: A

Rationale: The abbreviation PDR stands for Physician's Desk Reference, which is a widely used book containing information about prescription drugs, including their uses, side effects, and dosages. Therefore, the abbreviation PDR is associated with drugs. Choices B, C, and D are incorrect because PDR specifically relates to drugs and not procedures, books, or muscle groups.

5. He ate four pieces of fried chicken at dinner, and _____ vegetables.

A. no
B. some
C. little
D. few

Correct answer: A

Rationale: The correct answer is 'no' as it implies the absence of vegetables, indicating that he did not consume any vegetables along with the fried chicken. 'Some' (choice B) implies an unspecified quantity of vegetables were eaten, 'little' (choice C) implies a small amount of vegetables, and 'few' (choice D) is used for countable items, not for uncountable items like vegetables.
