Vocabulary HESI A2 Practice Test

Correct Answer: A

Rationale: The correct answer is A because a colon is used to introduce a list, an explanation, or a quotation. In this sentence, the colon introduces the purpose or goal of winning the race. The other choices do not require the use of a colon as they do not present a list, explanation, or quotation. Choice B is a list separated by commas. Choice C is a statement of time. Choice D is a list without any punctuation to introduce it. Therefore, choice A is the only one that correctly uses a colon to introduce the goal of winning the race.

Correct Answer: B

Rationale: The correct answer is B: Reddened or ruddy appearance. When someone is flushed, their skin appears red due to increased blood flow near the surface. This is typically caused by emotions, heat, or illness. Choice A, swollen, refers to an increase in size, not color. Choice C, discolored, implies a change in color different from redness. Choice D, pale, is the opposite of flushed, indicating a lack of color or a whitish appearance.

Correct Answer: B

Rationale: The correct answer is B because a contraindication is a specific reason or factor that makes it inadvisable to proceed with a particular treatment or procedure. It indicates a situation where the risks outweigh the potential benefits. Choice A is incorrect because a contraindication does not support performing an action. Choice C is incorrect as it describes a possible side effect, not a contraindication. Choice D is incorrect because a contraindication does not advise a specific action, but rather advises against it.

Correct Answer: B

Rationale: The correct answer is B: Guarded. Being circumspect means being cautious, prudent, and careful. In the context of patient records, being circumspect implies being guarded and discreet to protect patient confidentiality and privacy. Choice A is incorrect because circumspect does not imply acting carelessly. Choice C is incorrect because circumspect is the opposite of reckless. Choice D is incorrect because circumspect does not involve neglecting responsibilities.

Correct Answer: B

Rationale: The correct answer is B: Fontanel. Fontanels are soft spots on a newborn's head where the skull bones have not yet fused together, allowing for brain growth and flexibility during childbirth. Fistula (A) is an abnormal connection between organs, not related to newborn soft spots. Follicle (C) is a structure in the skin that produces hair, not related to fontanels. Fissure (D) refers to a narrow opening or crack, not associated with newborn soft spots. In summary, fontanels are unique anatomical structures specific to newborns that serve important developmental functions.
