Vocabulary HESI A2

Correct Answer: B

Rationale: The correct answer is B: swollen. When a blood vessel is distended, it means it has expanded or become enlarged due to increased pressure or volume of blood. Swollen accurately describes this condition. Choice A, overturned, is unrelated to the expansion of a blood vessel. Choice C, twisted, implies a different type of deformation. Choice D, overlong, does not accurately describe the condition of distended blood vessels.

Correct Answer: C

Rationale: The correct answer is C: Downpour. A deluge refers to a sudden and heavy rainfall, which is synonymous with a downpour. The word "deluge" specifically implies a large amount of water falling at once, making it the most appropriate synonym among the choices provided. Explanation of incorrect choices: A: Earthquake - An earthquake is a geological event involving the shaking of the ground, not related to heavy rainfall. B: Dimness - Dimness refers to low light levels and has no connection to heavy rainfall. D: Chasm - A chasm is a deep fissure or gorge in the earth, not related to heavy rainfall.

Correct Answer: C

Rationale: The correct answer is C: delirium tremens. This abbreviation is commonly used in healthcare to refer to a severe form of alcohol withdrawal characterized by confusion, agitation, hallucinations, and seizures. Deep tendon reflex (A) refers to a neurological assessment, descending thorax (B) is not a recognized medical term, and dextrose in water (D) is a solution used for intravenous administration. Therefore, C is the correct choice based on the context of patient care and medical terminology.

Correct Answer: C

Rationale: The correct answer is C, gelatinous. Viscous describes a substance that is thick and sticky, similar to the consistency of gelatin. Gelatinous specifically refers to something having a jelly-like or semi-solid texture, making it a suitable synonym for viscous. A: Fluid means a substance that flows easily, which is the opposite of viscous. B: Molten refers to something heated to a liquid state, not necessarily thick or sticky. D: Malleable means capable of being shaped or formed easily, which is unrelated to the thick and sticky nature of viscosity.

Correct Answer: A

Rationale: The correct answer is A: Shape. In the sentence, "contour" refers to the outline or shape of the patient's rash. This is evident as interns are observing, which implies visually analyzing the appearance. The word "contour" is commonly used to describe the shape or outline of an object or surface. Choices B, C, and D are incorrect because the sentence context does not suggest that the interns are looking for answers, measuring an amount, or assessing the extension of the rash.
