HESI A2 Practice Test Vocabulary

Correct Answer: B

Rationale: The correct answer is B: Reason. 'Rational' is related to reason, logic, and sound judgment. It implies making decisions based on logical thinking rather than emotions. Angry (A) does not relate to 'rational.' Rodent (C) and Proportion (D) are also unrelated to the meaning of 'rational.'

Correct Answer: C

Rationale: The correct answer is C: Surveillance. Under observation means being watched or monitored, which aligns with the definition of surveillance. Surveillance involves keeping a close watch over someone or something. Cognition (A) refers to mental processes, Isolation (B) means being separated or alone, and Assessment (D) involves evaluating or judging. These choices do not directly relate to being under observation.

Correct Answer: C

Rationale: The correct answer is C: Hold fast. Adhere means to stick firmly to something. In this context, "hold fast" best captures the idea of maintaining a strong attachment or connection. Choice A, remain intact, does not convey the idea of sticking or clinging. Choice B, loosen, is the opposite of adhere. Choice D, position next to, does not capture the concept of sticking or adhering to something. Therefore, choice C is the most appropriate synonym for adhere in this context.

Correct Answer: C

Rationale: The correct answer is C: Sense of balance. In the context provided, the word 'equilibrium' refers to the state of physical balance or stability. It is commonly used in the context of maintaining balance, such as in the inner ear. Choices A, B, and D do not align with the meaning of 'equilibrium' as they refer to different senses and abilities. Therefore, the correct answer is C as it directly relates to the concept of balance in this context.

Correct Answer: B

Rationale: The correct answer is B: Residual. In the context of the sentence, 'residual' refers to something that remains or is left over. The word 'resident' (A) refers to a person who lives in a particular place, 'resistance' (C) refers to the act of opposing or withstanding something, and 'resin' (D) is a sticky substance. Therefore, B is the correct choice as it directly relates to the meaning of something that remains.
