HESI A2 Practice Test Vocabulary

Correct Answer: D

Rationale: The correct answer is D: Soon to occur. 'Impending' means about to happen or approaching. In the context of the sentence, it suggests something that is close in time. Choice A, Very serious, is incorrect as 'impending' does not imply seriousness. Choices B and C, Required and Elective, are also incorrect as they do not relate to the time factor indicated by 'impending.'

Correct Answer: A

Rationale: The correct answer is A: Undesirable. In the context of the sentence, 'adverse' refers to negative or harmful effects. The word 'adverse' is commonly used to describe something that is unfavorable or harmful. In this case, the man is experiencing negative side effects from his medication, making 'undesirable' the most fitting interpretation. Incorrect Choices: B: Frequent - Frequency is not the primary meaning of 'adverse' in this context. C: Noticeable - While side effects may be noticeable, 'adverse' implies more than just being noticeable. D: Constant - 'Adverse' does not necessarily mean constant, it means unfavorable or harmful.

Correct Answer: C

Rationale: The correct answer is C: Threatening. The word 'ominous' is used to describe something that suggests harm or danger. In the sentence provided, the word 'ominous' is used to convey that the sign is foreboding or indicating something bad may happen. The other choices are incorrect because: A: A good omen means a sign of good luck, which is the opposite of ominous. B: Without deceit means honest or sincere, which is unrelated to the negative connotation of ominous. D: Full of thought means being contemplative or reflective, which does not align with the negative and threatening meaning of ominous.

Correct Answer: A

Rationale: The correct answer is A: Confinement away from the general population. Quarantine is a public health practice that separates and restricts the movement of individuals who may have been exposed to a contagious disease to prevent its spread. Choice B, specialist's care, is incorrect as it does not relate to quarantine. Choice C, experimental drug therapy, is incorrect as quarantine is about isolation, not drug treatment. Choice D, imprisonment in a rehabilitation unit, is incorrect as quarantine is a temporary isolation for health reasons, not a form of punishment or long-term confinement.

Correct Answer: B

Rationale: The correct answer is B: Convulsion. A paroxysm is defined as a sudden spasm or seizure, which is synonymous with convulsion. Symptom (A) refers to an indication of a condition, not the same as a spasm. Efficacy (C) means the ability to produce a desired or intended result, unrelated to sudden spasms. Embolism (D) is a blockage of a blood vessel, not related to spasms. Therefore, the correct choice is B as it directly relates to the sudden spasm characteristic of a paroxysm.
