Vocabulary HESI A2 Practice Test

Correct Answer: B

Rationale: The correct answer is B: Present on two sides. "Bilateral" refers to something that exists or occurs on two sides. For example, bilateral symmetry means that an object can be divided into two equal halves. Choice A is incorrect because "unilateral" means occurring on one side. Choice C is incorrect as it describes something random, not specifically on two sides. Choice D is incorrect because "bilateral" implies a presence on two sides, not the absence of occurrence.

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: B

Rationale: The correct answer is B: Respectability. AEGIS is commonly used to refer to protection, support, or sponsorship. Respectability aligns with the idea of upholding a positive reputation or being held in high regard, which reflects the protective nature associated with AEGIS. Relationship (A), Ramifications (C), and Responsibility (D) do not directly convey the protective or supportive connotations that AEGIS implies, making them incorrect choices.

Correct Answer: B

Rationale: The correct answer is B: Outdated. When a theory is considered obsolete, it means it is no longer relevant or valid due to new information or advancements. This makes it outdated and no longer useful for current understanding. Choices A, C, and D are incorrect because an obsolete theory is not up to date, innovative, or scientific - it is instead old and irrelevant.

Correct Answer: B

Rationale: The correct answer is B because hygiene refers to practices that promote cleanliness and good health. This includes actions such as handwashing, proper sanitation, and personal grooming.

Option D is incorrect as hygiene is not a type of infection but rather a set of practices to prevent infections.
