HESI A2 Vocabulary 2023

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.

Correct Answer: B

Rationale: The correct answer is B: stretch. When tubes distend, they expand or elongate due to internal pressure or force applied. This leads to stretching of the tube material. Flexing (choice A) implies bending, which is not the primary response when tubes distend. Solidifying (choice C) means to become solid, which is the opposite of what happens when tubes distend. Collapsing (choice D) is the opposite of stretching and occurs when tubes lose their internal pressure or support, leading to a decrease in size.

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: A

Rationale: The correct answer is A: Clumsy. 'Maladroit' means lacking skill or dexterity, often resulting in clumsiness. In the context of the sentence, it suggests that those who are maladroit (clumsy) should not become surgeons as surgery requires precision and skill. Explanation for other choices: B: Romantic - This choice is incorrect because 'maladroit' does not relate to being romantic. C: Untrained - This choice is incorrect as 'maladroit' is not specifically about lack of training, but about lack of skill or coordination. D: Self-conscious - This choice is incorrect as 'maladroit' does not imply being self-conscious, but rather lacking in skill or finesse.

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.
