Vocabulary HESI A2 Practice Test

Correct Answer: A

Rationale: The correct answer is A: buy. The sentence indicates that the person decided to purchase the car he had seen at the Ford dealer. "Buy" is the most appropriate choice as it aligns with the context of making a final decision to own the car. The other choices, B: rent, C: lease, and D: sell, do not fit the context as they imply actions different from making a purchase. Renting and leasing involve temporary ownership, while selling means getting rid of the car. Therefore, "buy" is the correct choice in this scenario.

Correct Answer: A

Rationale: The correct answer is A because 'legal' is directly modifying the noun 'resident,' indicating the status of being lawful within the context of residency. In contrast, choices B, C, and D use 'legal' as a noun or part of a noun phrase, not as an adjective directly modifying a noun. In choice B, 'legal' is part of the noun phrase 'legal action.' In choice C, 'legal' is part of the noun phrase 'that action.' In choice D, 'legal' is part of the noun phrase 'legal way.' Therefore, A is the only sentence where 'legal' is functioning as an adjective.

Correct Answer: B

Rationale: The correct answer is B: Degree of viscosity, how thick or thin a fluid is. Consistency refers to the thickness or thinness of a fluid, which is directly related to its viscosity. Viscosity is a measure of a fluid's resistance to flow, with thicker fluids having higher viscosity. Color (option A), taste (option C), and smell (option D) are not related to the concept of consistency in fluids. Color is a visual property, taste is a sensory perception, and smell is an olfactory sensation, none of which are indicative of a fluid's consistency.

Correct Answer: B

Rationale: The correct answer is B: had run. The use of "had run" indicates that the running action was completed before the policeman caught up with the man. This implies a sequence of events - first running, then catching up. The past perfect tense "had run" is appropriate here to show that the running occurred in the past before the catching up. A: "ran" - This choice implies a simultaneous action of running and catching up, which does not convey the correct sequence of events. C: "chased" - While this choice is grammatically correct, it does not accurately convey that the policeman caught up with the man through running. D: "drove" - This choice is incorrect as it suggests the policeman caught up with the man by driving, which is not mentioned in the sentence.

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.
