HESI A2 Vocabulary 2023

Correct Answer: D

Rationale: The correct answer is D: dizzy. Vertigo is a sensation of spinning or dizziness. Patients experiencing vertigo feel as if they or their surroundings are moving when they are not. Therefore, a vertiginous patient would be dizzy. Choices A, B, and C are incorrect because being on a liquid diet, lying flat, or being burned do not directly relate to vertigo or the symptoms associated with it.

Correct Answer: D

Rationale: The correct answer is D: Commotion. In the given sentence, 'tumult' is used to describe a state of confusion and disorder in the emergency room. A commotion refers to a noisy disturbance or uproar, which perfectly fits the context of the sentence. Siren (A) refers to a loud noise, not the overall chaotic situation. Distress (B) and suffering (C) are related to feelings of pain or discomfort, but they do not capture the sense of chaos and noise implied by 'tumult' in this context.

Correct Answer: D

Rationale: The correct answer is D: Fragile. In the sentence, 'tenuous' is used to describe the hold on reality as weak or delicate. The word 'fragile' best captures this meaning, as it implies something easily broken or damaged. Judicious (A) means showing good judgment, which is not relevant here. Deleted (B) means removed, which doesn't fit the context. Frantic (C) means wild or frenzied, which is not the intended meaning in this sentence. The key is to understand the context and choose the word that best conveys the intended meaning, which in this case is 'fragile.'

Correct Answer: B

Rationale: The correct answer is B: Radius. In the forearm, the radius is shorter than the ulna. The radius is located on the same side as the thumb, while the ulna is on the side of the pinky finger. The humerus is the upper arm bone, the scapula is the shoulder blade, and the fibula is a bone in the lower leg. So, the radius is the only bone among the choices that is actually located in the forearm and is shorter than its counterpart, the ulna.

Correct Answer: A

Rationale: The correct answer is A: Bitter. Acrid refers to a sharp and unpleasant taste or smell, often associated with bitterness. Bitter is the most synonymous term, as it conveys the same sharp and unpleasant quality. Smoky, nimble, and severe do not align with the definition of acrid, making them incorrect choices. Smoky refers to a smell associated with smoke, nimble relates to agility, and severe conveys seriousness or harshness, none of which capture the essence of acrid. Therefore, option A is the most appropriate synonym for acrid in this context.
