HESI A2 Vocabulary Quiz

1. Choose the meaning of the word 'mercurial' in the following sentence: 'Due to his mercurial temperament, Justin did not work well with others.'

Correct answer: B

Rationale: The word 'mercurial' in this sentence means unpredictable or prone to sudden changes in mood or behavior. Justin's temperament can be characterized as unpredictable, which is causing him to not work well with others. Choice A, 'Continuous,' does not align with the meaning of 'mercurial' as it implies a steady, uninterrupted flow. Choice C, 'Mercenary,' refers to being primarily motivated by money or reward, which is not the context here. Choice D, 'Miraculous,' means extraordinary or remarkable, which is not the intended meaning in this sentence.

2. A paroxysm is a sudden spasm. Another word for this might be ___________.

Correct answer: A

Rationale: The correct answer is A: "convulsion." A paroxysm is defined as a sudden spasm or convulsion. The word "convulsion" specifically refers to a violent and involuntary contraction or spasm of muscles, which aligns perfectly with the description of a paroxysm. On the other hand, choices B, C, and D are incorrect. "Symptom" (B) refers to a manifestation of a condition rather than a physical spasm. "Efficacy" (C) relates to effectiveness or success, not a sudden spasm. "Embolism" (D) refers to the obstruction of a blood vessel, which is unrelated to the concept of a sudden spasm. Therefore, convulsion is the most suitable synonym for a paroxysm in this context.

3. Someone who is Altruistic might also be called ______

Correct answer: B

Rationale: Altruistic individuals exhibit selfless concern for others, demonstrating a charitable nature. Therefore, being described as charitable aligns with the trait of altruism. Choice A, 'Selfish,' is the opposite of altruistic as it denotes concern only for oneself. Choice C, 'Greedy,' implies a strong desire for more and is not synonymous with altruism. Choice D, 'Hateful,' suggests a feeling of strong dislike, which is not reflective of altruistic behavior.

4. The abbreviation PDR refers to a ___________.

Correct answer: A

Rationale: The abbreviation PDR stands for Physician's Desk Reference, which is a widely used book containing information about prescription drugs, including their uses, side effects, and dosages. Therefore, the abbreviation PDR is associated with drugs. Choices B, C, and D are incorrect because PDR specifically relates to drugs and not procedures, books, or muscle groups.

5. What does intact mean?

Correct answer: B

Rationale: The correct answer is B: 'In place, unharmed.' 'Intact' refers to something that is whole, undamaged, or unharmed. Choices A, C, and D are incorrect because they describe states opposite to what intact means. 'Damaged,' 'Destroyed,' and 'Incomplete' all signify a lack of wholeness or harm, which is contrary to the meaning of intact.
