HESI A2 Vocabulary 2024

Correct Answer: B

Rationale: The correct answer is B: Into muscles. 'Intramuscularly' refers to the administration of a substance directly into the muscle tissue. In the context of the sentence, it indicates how the vaccine should be used. Choice A (Between muscles) is incorrect as it does not accurately reflect the meaning of 'intramuscularly.' Choice C (Without muscles) is incorrect as it is the opposite of the intended meaning. Choice D (On top of muscles) is also incorrect as it does not involve penetration into the muscle tissue. Therefore, the correct choice is B because it best aligns with the definition of 'intramuscularly.'

Correct Answer: C

Rationale: The correct answer is C: assumed. "Hypothetical" means based on an assumption or guess, not proven. It is not synonymous with "rigorous" (A), which means thorough and precise. It is also not related to "short-term" (B), which refers to a brief duration. Furthermore, "convinced" (D) implies a state of belief or certainty, which is contrary to the tentative nature of something that is hypothetical. Thus, the most suitable definition for hypothetical is "assumed" as it reflects the uncertain and speculative nature of a hypothesis.

Correct Answer: D

Rationale: The correct answer is D because the question states that the lump is palpable, meaning it can be felt. This indicates that the lump is physically detectable by touch, which is a characteristic of a palpable lump. Choices A, B, and C are incorrect because the question does not provide any information to suggest that the lump is malignant, has burst, or is warm. Therefore, the correct answer is D based on the specific information given in the question.

Correct Answer: D

Rationale: The correct answer is D: recurring. A chronic condition is one that persists over a long period of time or reoccurs frequently. This term specifically refers to a condition that is ongoing or repetitive in nature. A: harmless - This choice does not describe the duration or frequency of the condition, only that it is not harmful. B: critical - This choice implies the condition is severe or urgent, which is not necessarily the defining characteristic of a chronic condition. C: contagious - This choice refers to the ability of a condition to spread from person to person, which is not related to the duration or frequency of the condition.

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.
