HESI A2 Vocabulary 2024

Correct Answer: B

Rationale: The correct answer is B: parasite. A nit is a term used to refer to the egg or young form of a louse or other parasitic insect. Nits are commonly found in hair and are a common sign of a head lice infestation. Choice A (abscess) is incorrect because an abscess is a localized collection of pus caused by an infection. Choice C (bandage) is incorrect because a bandage is a material used to cover and protect wounds. Choice D (infection) is incorrect because an infection is a condition caused by the invasion of harmful microorganisms into the body. Therefore, the correct answer is B as nits specifically refer to parasites, such as lice eggs.

Correct Answer: C

Rationale: The correct answer is C: meets requirements. When a pharmacy is in compliance, it means it follows all laws, regulations, and standards set by regulatory bodies. This ensures the pharmacy operates ethically and safely. Showing flexibility (A) or receiving criticism (B) are not indicators of compliance. Being disciplined (D) indicates non-compliance.

Correct Answer: D

Rationale: The correct answer is D: A public health association. The CDC stands for Centers for Disease Control and Prevention, a well-known organization dedicated to protecting public health and safety. This choice is correct because the CDC is not an online social network (A), a test for postgraduate students (B), or a pharmaceutical company (C). The CDC's primary focus is on disease control, prevention, and public health promotion, making it the best description among the given options.

Correct Answer: C

Rationale: The correct answer is C: Bruises. A contusion refers to a bruise caused by a blunt force trauma that damages the small blood vessels beneath the skin without breaking the skin itself. In the given sentence, the context of 'treated on-site' implies a minor injury that can be managed without the need for immediate medical attention. A: Breaks - This term typically refers to fractures or disruptions in the continuity of bones, not applicable in the context of the sentence. B: Disorientation - This term refers to a state of confusion or loss of direction, not related to physical injuries such as contusions. D: Abrasions - Abrasions are superficial wounds where the skin is scraped or rubbed off, different from contusions which involve internal bleeding beneath the skin.

Correct Answer: A

Rationale: The correct answer is A: Unfavorable. In the sentence, 'adverse' is used to describe a reaction caused by the medicine, indicating that it is not beneficial and has negative effects. 'Unfavorable' aligns with this meaning as it conveys something that is not conducive or adverse. The other choices are incorrect because B: Contrary means opposite, C: Noticeable means easily observed, and D: Startling means surprising, none of which capture the negative connotation of 'adverse' in this context.
