HESI A2 Vocabulary 2023

Correct Answer: B

Rationale: The correct answer is B: Radius. In the forearm, the radius is shorter than the ulna. The radius is located on the same side as the thumb, while the ulna is on the side of the pinky finger. The humerus is the upper arm bone, the scapula is the shoulder blade, and the fibula is a bone in the lower leg. So, the radius is the only bone among the choices that is actually located in the forearm and is shorter than its counterpart, the ulna.

Correct Answer: A

Rationale: The correct answer is A: Collection. A compendium refers to a concise collection of information or knowledge on a specific subject. It is a comprehensive summary or compilation. "Aptitude" refers to a natural ability or talent, not related to a compendium. "Conclusion" refers to the end or result of an argument or discussion, not synonymous with compendium. "Humor" refers to the quality of being amusing or comic, which is unrelated to the concept of a compendium. Therefore, A is the most appropriate synonym for compendium in this context.

Correct Answer: A

Rationale: The correct answer is A: Add water to. In the context of diluting medicine, the word 'dilute' means to make the substance less concentrated by adding a solvent, usually water. This process helps in reducing the potency of the medicine for safer consumption. The other choices are incorrect as they do not accurately reflect the meaning of 'dilute' in the given context. Choice B (Reduce by half) does not necessarily involve adding a solvent, choice C (Warm up) refers to increasing temperature, and choice D (Decontaminate) is about removing impurities, none of which align with the meaning of dilute.

Correct Answer: D

Rationale: The correct answer is D: Lasting a long time. In the sentence, 'persistent' is used to describe the cold that the elderly patient has been fighting, indicating that the cold has been ongoing and enduring. This aligns with the definition of 'persistent' as something that continues for an extended period. Choices A, B, and C are incorrect because 'persistent' does not mean typical, harmless, or without a cure in this context. The key to selecting the correct answer is understanding the context in which the word is used and its meaning in relation to that context.

Correct Answer: A

Rationale: The correct answer is A: magnesium. Magnesium is an essential electrolyte in the human body, playing a crucial role in nerve function, muscle contraction, and maintaining a healthy heart rhythm. It is commonly found in bones and helps regulate blood pressure. Choice B: manganese is not a primary electrolyte in the human body, though it is an essential trace mineral. Choice C: magnetite is a type of mineral and not an electrolyte found in the human body. Choice D: manganite is a mineral compound and not an electrolyte present in the human body.
