Vocabulary for HESI A2

1. What does the word BILATERAL mean?

A. 2-sided
B. Straight
C. Symmetrical
D. On one side

Correct answer: A

Rationale: The word 'bilateral' means having or relating to two sides. It is often used to describe something that occurs on both sides, such as bilateral symmetry in which an object is symmetrical on two sides. Choice B, 'Straight,' does not capture the meaning of bilateral. Choice C, 'Symmetrical,' while related, does not specifically convey the idea of something pertaining to two sides. Choice D, 'On one side,' is the opposite of what bilateral means.

2. What does 'expand' mean?

A. To decrease in size
B. To increase in size or amount
C. To spread out
D. To eliminate

Correct answer: B

Rationale: The correct answer is B. 'Expand' means to increase in size or amount. Choice A, 'To decrease in size,' is the opposite of what 'expand' means. Choice C, 'To spread out,' is related to expanding but does not precisely define the term. Choice D, 'To eliminate,' is not synonymous with the term 'expand.'

3. Which phrase correctly completes the sentence? 'As we celebrated the start of the evening festivities, our glasses ___ and a toast was made by our host.'

Correct answer: C

Rationale: The correct answer is 'Were raised.' This phrase is the correct passive form, indicating the action of lifting the glasses during the toast.
