HESI A2 Vocabulary 2023

Correct Answer: C

Rationale: Step 1: Understand the definition - Bifurcate means to divide or split into two branches or forks. Step 2: Analyze the choices - A is incorrect as bifurcate does not involve folding. B is incorrect as it refers to flowering, not dividing. D is incorrect as it involves piercing, not dividing. Step 3: Choose the correct answer - C accurately describes the act of dividing into two forks, aligning with the definition of bifurcate. Summary: Choice C is correct as it directly relates to the definition of bifurcate, while the other choices are incorrect as they do not capture the essence of the word.

Correct Answer: B

Rationale: The correct answer is B: Drooping or loose. Flaccid means lacking firmness or stiffness, often used to describe something that is limp or lacking in strength or vigor. In this context, flaccid refers to something that is drooping or loose. Choice A is incorrect as light-colored does not relate to the definition of flaccid. Choice C is incorrect as uncontaminated is not a synonym of flaccid. Choice D is incorrect as unusually aggressive is unrelated to the meaning of flaccid.

Correct Answer: A

Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.

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: C

Rationale: The correct answer is C: Gums and teeth. When people masticate, they use their gums to hold the food in place and their teeth to break down the food into smaller pieces through chewing. This process is essential for digestion. Choices A, B, and D are incorrect because fingers, eyes, ears, heels, and toes are not involved in the mastication process.
