Vocabulary for HESI A2

Correct Answer: A

Rationale: The correct answer is A: Occurrence. Incidence refers to the rate or frequency of occurrence of something, such as a disease or an event. It represents the number of new cases in a specific population over a certain period of time. Choice B, Disappearance, is incorrect as it refers to something vanishing or ceasing to exist. Choice C, Growth, is incorrect as it denotes an increase or expansion in size or quantity. Choice D, Repetition, is incorrect as it signifies the act of doing something over and over again. Thus, the most appropriate definition of Incidence is A: Occurrence, as it best aligns with the concept of frequency or rate of new instances.

Correct Answer: B

Rationale: The correct answer is B: Broadcasting it. When someone is disseminating information, they are distributing or spreading it widely to reach a larger audience. This involves sharing the information openly and making it accessible to others. Choices A, C, and D are incorrect because disseminating information is the opposite of hiding, destroying, or withholding it. Dissemination involves sharing knowledge or data, not concealing, destroying, or keeping it secret.

Correct Answer: B

Rationale: The correct answer is B: Limp or lacking tone. Flaccid refers to a lack of firmness or stiffness in muscles or tissues. This term is used to describe a state of being weak or lacking in strength. Choice A, Rigid, is the opposite of flaccid as it means stiff or firm. Choice C, Tense, refers to being tight or strained, which is different from the relaxed and weak state of flaccid. Choice D, Swollen, means being enlarged due to fluid accumulation, which is not related to the lack of tone associated with flaccid. Thus, the correct answer is B as it best describes the meaning of flaccid.

Correct Answer: C

Rationale: The correct answer is C: Thickness. Consistency refers to the degree of thickness or firmness in a substance. This choice best captures the meaning of consistency in terms of texture and quality. Appearance (A) does not directly relate to the concept of consistency. Volatility (B) refers to the tendency of a substance to change rapidly, which is the opposite of consistency. Color (D) is not related to the concept of consistency in this context. Therefore, option C is the most appropriate synonym for consistency in this scenario.

Correct Answer: A

Rationale: The correct answer is A: under. "Under anesthesia" is the correct phrase indicating the patient is in a state of anesthesia. "Within anesthesia" (B) is incorrect as "within" does not describe the state of being under anesthesia. "With anesthesia" (C) is incorrect because "with" does not convey the state of being under the influence of anesthesia. "Over anesthesia" (D) is incorrect as "over" does not appropriately describe the state of being under anesthesia. Thus, the correct choice is A.
