Vocabulary HESI A2 Practice Test

Correct Answer: A

Rationale: The correct answer is A: Widespread. Ubiquitous means something that is present or found everywhere. This word conveys the idea of being widespread or omnipresent. The other choices are incorrect because B: Miniscule means very small, C: Invalid means not valid or acceptable, and D: Unit refers to a single entity or a distinct part. Therefore, only choice A aligns with the definition of ubiquitous.

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: Toward the midline. In anatomical terms, "medial" refers to a position closer to the midline of the body. This is the correct choice as it accurately describes the location in relation to the midline. Choices A, C, and D are incorrect because "Away from the midline," "At the side," and "Below the body" do not accurately define the term "medial" in anatomical language.

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: Emetic. An emetic is a medicine that induces vomiting. This is achieved by irritating the stomach lining, leading to the body expelling its contents. A: Laxative helps with bowel movements, not vomiting. C: Vaccine is a substance that stimulates the immune system to produce immunity to a specific disease, not induce vomiting. D: Analgesic is a pain-relieving medication, not used for inducing vomiting.
