Quizlet Vocabulary HESI A2

Correct Answer: B

Rationale: The correct answer is B: Distinct or separate. Discrete refers to individual, separate entities or items. It is the opposite of continuous, making choice A incorrect. Choices C and D are also incorrect as they do not convey the meaning of distinct or separate, which is the essence of the term 'discrete'. In summary, the term 'discrete' specifically refers to items that are distinct and separate from each other, making choice B the correct answer in this context.

Correct Answer: B

Rationale: The correct answer is B: Swollen. When a blood vessel is distended, it means it has expanded or enlarged beyond its normal size. Swelling refers to an increase in size due to fluid accumulation. In the context of blood vessels, distention typically indicates swelling or enlargement of the vessel. Therefore, a distended blood vessel is swollen. Incorrect choices: A: Narrow - This is incorrect as distended means expanded or enlarged, not narrowed. C: Flat - This is incorrect as distended implies an increase in size, not a flat shape. D: Dilated - While dilation can refer to an increase in size, distended specifically implies swelling due to fluid accumulation, making this choice less precise than "swollen."

Correct Answer: D

Rationale: The correct answer is D: Ventral. The term "ventral" refers to the lower surface of a structure in anatomical terms. In anatomy, ventral typically describes the front or lower part of the body. This term is commonly used to indicate the underside of an organism or structure. Rationale: 1. "Inferior" (Choice A) typically refers to something below or lower in position but is a general term and not specific to the lower surface of a structure. 2. "Transverse" (Choice B) refers to a horizontal plane that divides the body into upper and lower portions, not specifically the lower surface of a structure. 3. "Dorsal" (Choice C) refers to the upper surface or back of a structure, opposite to the ventral side.

Correct Answer: B

Rationale: The correct answer is B, burdensome. ONEROUS means involving a great amount of effort or difficulty, hence burdensome. This is because the word is derived from the Latin word "onus" meaning burden. Choices A, C, and D are incorrect because ONEROUS does not mean easy, interesting, or relaxing. The word specifically conveys a sense of heaviness or difficulty, making "burdensome" the most appropriate synonym.

Correct Answer: C

Rationale: The correct answer is C: Etiology. Etiology refers to the cause or origin of a disease, in this case, the flu epidemic of 1918. The question explicitly states that the etiology remains unknown, indicating that the cause of the epidemic is still a mystery. Pathology (A) refers to the study of diseases rather than their cause. Transmission (B) relates to how a disease spreads, not its origin. Mortality rate (D) is a measure of the number of deaths caused by a disease and is not directly related to determining the cause of the epidemic. Therefore, the correct answer is C because it specifically addresses the unknown cause of the flu epidemic.
