HESI A2 Vocabulary Quiz

1. Choose the meaning of the word 'disintegrates' in the following sentence: 'It disintegrates in the mouth within seconds after placement on the tongue, allowing its contents to be swallowed with or without water.'

Correct answer: D

Rationale: The word 'disintegrates' means to break apart into smaller parts or fragments. In the sentence, it describes the process of the substance breaking down in the mouth. Therefore, the most appropriate meaning is 'Fragments.' 'Evaporates' means to turn into vapor, 'Fizzes' refers to the production of bubbles, and 'Deviates' means to depart from the norm, making them incorrect choices in the context of the sentence.

2. She went to the party _____ her dislike for the host.

Correct answer: B

Rationale: The correct answer is 'despite.' 'Despite' is used to indicate a contrast between attending the party and the dislike for the host. 'Because of' (choice A) is incorrect as it would imply that she attended the party specifically because of her dislike for the host. 'In spite of' (choice C) has the same meaning as 'despite' but is less commonly used. 'Due to' (choice D) is incorrect as it is used to show causation, which does not fit the context of the sentence.

3. Which sentence correctly uses a semicolon?

Correct answer: B

Rationale: The sentence 'She likes apples; oranges are her favorite.' correctly uses a semicolon to connect two related independent clauses. The semicolon is used to separate two closely related ideas in a way that is stronger than a comma but not as final as a period. Choice A is incorrect because the conjunction 'but' is missing before 'I can't go out tonight.' Choice C is incorrect as the conjunction 'and' after the semicolon is unnecessary and disrupts the flow of the sentence. Choice D is incorrect because the semicolon is incorrectly placed before 'oranges are better,' where a comma or period would be more appropriate.

4. Select the meaning of the word 'distended' in the sentence: 'Wracked by abdominal pain, the victim of food poisoning moaned and rubbed his distended belly.'

Correct answer: C

Rationale: The correct answer is C: 'swollen.' In the context provided, 'distended' refers to the victim's belly being enlarged or bloated due to abdominal pain. This matches the description of the victim moaning and rubbing his belly, indicating discomfort from swelling. Choices A, B, and D are incorrect. 'Concave' means having an inward curve, opposite to the intended meaning. 'Sore' means experiencing pain or discomfort, which is not directly related to the physical enlargement described in the sentence. 'Empty' means containing nothing, which contrasts with the idea of the belly being visibly enlarged or bloated.

5. Which muscle in the shoulder is the deltoid?

Correct answer: C

Rationale: The deltoid muscle is located in the shoulder area. It is a rounded, triangular muscle that covers the shoulder joint and is responsible for lifting the arm and providing shoulder stability. The other options provided, dendrite, delphic, and dentate, are not muscles in the shoulder region.
