Vocabulary HESI A2 Practice Test

Correct Answer: B

Rationale: The correct answer is B: Complaining. Querulous means constantly complaining or expressing dissatisfaction. This is because the word is derived from the Latin word "queri" which means to complain. Shouting (A), crying (C), and praising (D) do not align with the definition of querulous. Shouting is about making a loud noise, crying is about expressing sadness or distress, and praising is about expressing approval or admiration. Therefore, B is the most appropriate choice that accurately reflects the meaning of querulous.

Correct Answer: B

Rationale: The correct answer is B because hygiene refers to practices that promote cleanliness and good health. This includes actions such as handwashing, proper sanitation, and personal grooming. Option A is close but doesn't emphasize the preventive aspect. Option C is incorrect as hygiene is not specifically related to dietary health. Option D is incorrect as hygiene is not a type of infection but rather a set of practices to prevent infections.

Correct Answer: B

Rationale: The correct answer is B: The noise did not affect his sleep. 'Affect' is a verb meaning to influence or have an impact on something. In this sentence, the noise did not influence his sleep, making it the correct usage. Choice A uses 'effect' incorrectly as a noun. Choice C uses 'affect' incorrectly as a future tense verb. Choice D uses 'affect' correctly but in the negative, making it incorrect.

Correct Answer: B

Rationale: The correct answer is B: Activate. Instigate means to initiate or start something, typically something negative or challenging. In this context, it refers to initiating an action or process. Deactivate (A) means to make something inactive, which is the opposite of instigate. Suppress (C) means to prevent or restrain, not initiate. Evaluate (D) means to assess or judge, not start or activate. Therefore, B is the correct answer as it aligns with the meaning of instigate in initiating or activating a process.

Correct Answer: B

Rationale: The correct answer is B: Reddened or ruddy appearance. When someone is flushed, their skin appears red due to increased blood flow near the surface. This is typically caused by emotions, heat, or illness. Choice A, swollen, refers to an increase in size, not color. Choice C, discolored, implies a change in color different from redness. Choice D, pale, is the opposite of flushed, indicating a lack of color or a whitish appearance.
