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. She was so mad at her boyfriend, she _____ on him when he called.

A. hung up
B. picked
C. held
D. held on

Correct answer: A

Rationale: The correct answer is 'A: hung up.' In this context, 'hung up' is the correct phrasal verb to indicate ending a phone call abruptly. The phrase 'hung up' means to abruptly end a phone call. The other choices do not fit the context. 'Picked' implies selecting something, 'held' means to grasp or support something, and 'held on' implies maintaining a grip or connection rather than ending the call.

3. Which term refers to the surgical removal of an organ's contents?

A. Excretion
B. Evisceration

Correct answer: B

Rationale: The correct answer is B, 'Evisceration.' Evisceration specifically means the surgical removal of an organ's contents. Choice A, 'Excretion,' is the process of eliminating waste products from the body and is not related to surgical procedures. Choice C, 'Incision,' refers to the act of cutting into the body, commonly done in surgeries but not specifically related to removing organ contents.

Rationale: The correct use of 'affect' is to show influence or make a difference. In this context, 'The noise did not affect his sleep' is the correct usage as noise can impact one's ability to sleep. Choice A is incorrect as 'affect' is commonly confused with 'effect.' Choice C is incorrect as 'affect' is not typically used to refer to the impact of light on eyes. Choice D is incorrect as 'affect' is not typically used to describe the impact of weather on mood.

Choice C, 'Care for,' is also the opposite of disregard, as caring for something implies giving it importance and attention.
