HESI A2

Vocabulary for HESI A2

1. The voice box may be called the ______

A. Pharynx
B. Larynx
C. Trachea
D. Esophagus

Correct answer: B

Rationale: The correct term for the voice box is the larynx. The pharynx is part of the throat involved in swallowing and breathing but not the voice production. The trachea is the windpipe responsible for air passage, and the esophagus is the tube that carries food from the mouth to the stomach. Therefore, in this context, the larynx is the most appropriate term.

2. What does 'Parameter' mean?

A. A constant variable
B. A characteristic or constant factor
C. A measurable limit
D. A calculated risk

Correct answer: B

Rationale: The correct answer is B: 'A characteristic or constant factor.' In the context of systems or experiments, a parameter is a fixed element that influences the behavior or outcome. It is not a variable like in choice A, which can change. Choice C, 'A measurable limit,' is incorrect as a parameter is not necessarily a physical limit but a defining factor. Choice D, 'A calculated risk,' is unrelated to the definition of a parameter.

3. A surgeon who is adroit might be described as ______.

A. Careless
B. Skillful
C. Inexperienced
D. Lazy

Correct answer: B

Rationale: The word 'adroit' means skillful or proficient. A surgeon who is adroit would be highly skilled and proficient in their work. Therefore, the most appropriate description for a surgeon who is adroit is 'skillful.' Choices A, C, and D are incorrect because they do not reflect the positive attribute associated with being adroit.

4. Which sentence uses the correct form of the verb?

A. She has completed the project
B. She has completed the project
C. She has been completed the project
D. She has completed the project

Correct answer: B

Rationale: The correct answer is 'She has completed the project.' The sentence uses the present perfect tense with 'has completed,' which is the correct form of the verb. Choice A is incorrect due to the subject-verb agreement error ('She' requires 'has' instead of 'have'). Choice C is incorrect as it changes the meaning by using the passive voice 'has been completed' instead of the active voice. Choice D is incorrect as 'complete' should be 'completed' to match the present perfect tense.

5. Which sentence is grammatically correct?

A. Somebody left their jacket on the train
B. Somebody left his or her jacket on the train
C. His jacket was left on the train
D. His or her jacket was left on the train

Correct answer: B

Rationale: The sentence 'Somebody left his or her jacket on the train.' is grammatically correct and respects gender neutrality. 'Somebody' is singular, so the pronoun 'their' in choice A is incorrect. Choice C changes the subject from 'somebody' to 'his,' making it grammatically incorrect. Choice D is grammatically correct, but it is less concise and more awkward than choice B, which smoothly combines 'his' and 'her' for gender-neutral language.
