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. 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.

3. The eye drops were intended to _____ the pupils for the eye exam.

A. dilate
B. constrict
C. enlarge
D. decrease

Correct answer: A

Rationale: The correct answer is 'dilate.' Eye drops are used to dilate the pupils, meaning to widen or enlarge them, which is necessary for an eye exam to allow more light to enter the eye. 'Constrict' (choice B) means to make smaller, which is the opposite effect needed for an eye exam. 'Enlarge' (choice C) is similar in meaning to dilate but is not the correct term used in this context. 'Decrease' (choice D) means to make less or reduce, which is also the opposite of what is required for an eye exam.

4. Which word is used incorrectly? 'Which procedure for giving injections was explained thoroughly to the student nurses.'

A. procedure
B. was
C. explained
D. thoroughly

Correct answer: B

Rationale: The correct answer is 'B - was.' In the original question, 'were' is incorrectly used as the verb, which should be singular to match the singular subject 'procedure.' The subject 'procedure' requires the singular form 'was' instead of the plural form 'were.' Choices A, C, and D are all used correctly in the sentence.

5. What is the meaning of Regulations?

A. Rules for Conduct
B. Official Standards
C. Personal Guidelines
D. Suggestions

Correct answer: A

Rationale: Regulations refer to rules or directives established by authorities to govern conduct or actions. Therefore, the correct answer is A - 'Rules for Conduct.' Choice B, 'Official Standards,' is incorrect as regulations go beyond just setting standards to include specific rules for behavior. Choice C, 'Personal Guidelines,' is incorrect as regulations are not individualized but are generally applicable rules. Choice D, 'Suggestions,' is incorrect as regulations are mandatory and carry legal weight, unlike suggestions which are optional and not binding.
