HESI A2 Practice Test Vocabulary

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: D

Rationale: The correct answer is D: Discharge. Flux refers to the process of flowing or continuous change. Discharge aligns with this definition as it signifies the release or movement of something, reflecting the idea of flow or change. Quantity (A) refers to amount, Inflation (B) refers to a rise in prices, and Strength (C) refers to power or energy, none of which directly relate to the concept of flux.

Correct Answer: C

Rationale: The correct answer is C: Preventive measure. A precaution is a preventive action taken to avoid potential harm or danger. Precautions are proactive steps to prevent negative outcomes. "Rule" (A) is too general and does not specifically imply preventative action. "Routine procedure" (B) suggests a regular process but may not necessarily be taken as a precaution. "Habit" (D) refers to a behavior done regularly and may not always be related to preventing harm. Therefore, C is the best choice as it directly relates to taking action to prevent potential risks.

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: 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.
