HESI A2 Practice Test Vocabulary

Correct Answer: A

Rationale: The correct answer is A: Prefix. A prefix is a word part placed before a base word to change its meaning. It comes before the root word and alters its definition. Prefixes are essential in forming new words and expanding vocabulary. Choice B: Affix is a broad term that refers to both prefixes and suffixes. While technically correct, it is not as specific as prefix in this context. Choice C: Suffix is a word part placed after a base word to change its meaning. It is the opposite of a prefix. Choice D: Vocab is short for vocabulary and does not relate to the word part placed before a word to change its meaning.

Correct Answer: A

Rationale: The correct answer is A: Regimen. A regimen refers to a systematic plan or set of rules to follow, which aligns with the phrase 'a system of procedures to follow'. Regime (B) typically refers to a government or ruling system, not specific procedures. Testament (C) refers to a will or statement of belief, unrelated to procedures. Treatment (D) refers to medical care or a way of dealing with something, not a set of procedures. Therefore, A is the best choice as it directly reflects the meaning of the given phrase.

Correct Answer: B

Rationale: The correct answer is B because anticipatory grieving refers to the process of mourning and coping with an expected loss before it occurs. In this case, the patient who will have their left leg amputated below the knee tomorrow is facing an imminent loss of a body part, leading to anticipatory grief. This situation involves emotional preparation and adjustment to the upcoming change, making it the best example of anticipatory grieving. Choice A is incorrect as giving birth to twins, although challenging, does not involve an impending loss that anticipatory grieving typically pertains to. Choice C is incorrect as experiencing pain during physical therapy does not necessarily involve grieving for a loss. Choice D is incorrect as being discharged after a hospital stay does not involve an impending loss that would lead to anticipatory grieving.

Correct Answer: B

Rationale: The term 'biologists' in the sentence functions as a subject and represents a person, place, thing, or idea. In this case, 'biologists' refers to individuals who study wildlife. Therefore, 'biologists' is a noun, making choice B the correct answer. Adjectives describe nouns, verbs indicate actions or states, and conjunctions connect words or phrases. In this sentence, 'biologists' is not describing anything, not an action, and not connecting elements, ruling out choices A, C, and D as incorrect.

Correct Answer: C

Rationale: The correct answer is C: Responsible. In the context of the sentence, 'accountable' means being responsible for something. The night nursing staff has the duty to maintain and manage the records, thus they are accountable. A: Receptive - This word means open or willing to accept new ideas, not relevant in the context of being accountable for records. B: Notorious - This word means famous for something bad, which is not applicable in this scenario. D: Preoccupied with - This word means to be excessively concerned or worried about something, not synonymous with being accountable for records.
