HESI A2 Practice Test Vocabulary

Correct Answer: C

Rationale: The correct answer is C: Immigrant. This term specifically refers to someone who has come to settle in the United States, indicating the intention to establish permanent residence. "Immigrate" (A) is incorrect as it is the action of moving to another country. "Migrate" (B) is incorrect as it refers to moving from one place to another without the connotation of settling permanently. "Emigrant" (D) is also incorrect as it refers to someone leaving their own country to settle elsewhere, not specifically in the United States. Therefore, choice C is the most appropriate term for someone coming to settle in the United States.

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: Rationale: 1. 'Impervious' means not affected or unaffected by something. 2. In the given sentence, it implies that the subject is not impacted by something. 3. Choices A, B, and D do not align with the meaning of 'impervious.' 4. Choice A suggests coping well, which is different from being unaffected. 5. Choice B implies enjoyment, unrelated to being unaffected. 6. Choice D suggests being very sensitive, opposite to being impervious.

Correct Answer: B

Rationale: The correct answer is B: Stimuli. The noun 'stimulus' follows the regular rule for forming plurals in English by adding 's' to the end of the word. In this case, 'stimulus' becomes 'stimuli' in plural form. Incorrect choices: A: Stimulus - Singular form, not plural. C: Stimulis - Incorrect spelling, should be 'stimuli' for plural. D: Stimula - Incorrect form, does not follow the rule for forming plurals in English.

Correct Answer: A

Rationale: The correct answer is A: Protective device. A cast is a rigid protective device used to immobilize and support a broken or injured limb during the healing process. The nurse assisted in the removal of the cast, which indicates it was a protective device. The other choices (B: Medicated sleeve, C: Sling, D: Bandage) do not accurately describe a cast and its purpose in immobilizing and supporting a limb. A cast is not a sleeve with medication, a sling for support, or a simple bandage for wound protection.
