HESI A2 Practice Test Vocabulary

Correct Answer: B

Rationale: The correct answer is B: Destructive. 'Pernicious' means causing harm in a subtle or gradual way. It is commonly used to describe something that has a destructive or harmful effect. The word 'valued' (A) means cherished or esteemed, not harmful. 'Finicky' (C) means overly picky or fussy, not harmful. 'Perpetual' (D) means constant or never-ending, not necessarily harmful. Therefore, the most appropriate choice is B as it aligns with the definition and common usage of 'pernicious.'

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.

Correct Answer: A

Rationale: The correct answer is A: Chronology. Chronology refers to the arrangement of events in the order of their occurrence. This term is specifically used to describe the chronological sequence of events. Notation (B) refers to symbols or marks used to represent something, not the order of events. Documentation (C) refers to the process of recording or providing evidence, not necessarily in chronological order. Helicon (D) is a term not related to the order of events. Therefore, A is the correct answer as it directly relates to the description of events in the order of their occurrence.

Correct Answer: A

Rationale: The correct answer is A: Gradual. In the context of disease development, "insidious" means slow and subtle in onset. This term implies a gradual progression without immediate noticeable symptoms. Choice B, momentous, means significant or important, which is not related to the gradual nature of the disease. Choice C, sudden, is the opposite of insidious, indicating a rapid onset. Choice D, innocuous, means harmless, which is not relevant to the negative connotation of insidious in disease development.

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.
