Vocabulary HESI A2

1. Select the meaning of the underlined word in the following sentence. All volatile liquids should be stored and labeled correctly.

A. Unstable
B. Abnormal
C. Lethal
D. Blended

Correct answer: A

Rationale: In the context of the sentence, 'volatile' means likely to change rapidly and unpredictably or evaporate quickly. When referring to liquids, volatile typically implies that the liquids are unstable and can easily change from liquid to gas. Therefore, the most appropriate meaning of 'volatile' in this sentence is 'unstable.' Choices B, C, and D are incorrect because 'abnormal' and 'lethal' do not capture the essence of rapid change or evaporation associated with volatile liquids, while 'blended' is unrelated to the characteristics of volatile liquids described in the sentence.

2. What does it mean if a patient is lethargic?

A. Active
B. Exhausted
C. Confused
D. Restless

Correct answer: B

Rationale: Lethargic means feeling exhausted or sluggish. Being lethargic is the opposite of being active (choice A), confused (choice C), or restless (choice D). When a patient is lethargic, they lack energy and may appear tired or sluggish.

3. The bad smell made him __________.

A. Gag
B. Enjoy
C. Remember
D. Attach

Correct answer: A

Rationale: The bad smell would likely make him gag, which is a physical reaction to an unpleasant odor. Gagging is a common response to strong or foul smells as the body seeks to expel the offending odor. Enjoy, Remember, and Attach do not accurately reflect a likely reaction to a bad smell.

4. Choose the meaning of the word 'tremulous' in the following sentence: 'The patient held out a tremulous hand and grasped the paperwork.'

A. Wrinkled and wizened
B. Pale and lifeless
C. Clenched and arthritic
D. Quivering and weak

Correct answer: D

Rationale: In this sentence, the word 'tremulous' is used to describe the patient's hand. When someone's hand is described as tremulous, it means it is quivering or shaking, indicating weakness or distress. Therefore, the correct meaning of 'tremulous' in this context is quivering and weak. Choices A, B, and C are incorrect because they do not capture the specific meaning of 'tremulous' in this context. 'Wrinkled and wizened' refers to being old and withered, 'pale and lifeless' describes a lack of color and vitality, and 'clenched and arthritic' implies a tight grip and joint inflammation, none of which accurately represent the trembling or shaking nature of a tremulous hand.

5. What does Lateral mean?

A. Near the midline
B. Away from the midline
C. At the top of the body
D. On the side

Correct answer: D

Rationale: The correct answer is D: 'On the side.' Lateral means situated on the side or away from the midline. Choices A, B, and C are incorrect because lateral specifically refers to a position that is situated away from the midline, not near it, at the top of the body, or on the side.
