HESI A2 Practice Test Vocabulary

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: 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: 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: 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: D

Rationale: The correct answer is D: Basic. In the context of the sentence, 'fundamental' means basic, essential, or foundational. The term 'fundamental' refers to something that is crucial, primary, or indispensable. It is not synonymous with the other choices. A: Appropriate does not capture the essence of 'fundamental.' B: Underlying is related but doesn't fully convey the sense of essentialness. C: Dosage is completely unrelated to the meaning of 'fundamental' in this context. So, the correct choice is D as it best aligns with the meaning of 'fundamental' in the sentence.
