HESI A2 Vocabulary 2023

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.

Correct Answer: D

Rationale: The correct answer is D, "To move side to side." In the context of the sentence, 'yaw' refers to a horizontal movement of the robotic arm requiring adjustment. This movement aligns with the definition of yaw as a side-to-side motion, commonly used in aviation and robotics. Choice A, "To gape open," is incorrect as it does not fit the context of the sentence. Choice B, "To move up and down," does not align with the horizontal movement described. Choice C, "To close tightly," is also incorrect as it does not relate to any form of movement but rather a stationary action.

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: B

Rationale: The correct answer is B: quite stubborn. "Obdurate" means stubborn or refusing to change one's opinion or course of action. Therefore, a patient who is especially obdurate would be characterized as being quite stubborn. The other choices are incorrect because being obdurate does not necessarily have any direct correlation with being very large (A), easily upset (C), or ready to go home (D). It specifically refers to being stubborn or resistant to change, making choice B the most fitting description.
