HESI A2 Vocabulary Practice Test

Correct Answer: B

Rationale: The correct answer is B: Outdated. Obsolete means no longer in use or relevant due to being outdated. Innovation (A) means introducing something new, effective (C) means successful in producing a desired or intended result, and advanced (D) means at a higher level of progress or development. In this context, the term 'obsolete' specifically refers to something that is no longer current or useful, making choice B the most appropriate answer.

Correct Answer: A

Rationale: The correct answer is A because it follows the structure of passive voice (subject + to be verb + past participle). In this sentence, "The homework was completed by the student," the focus is on the action being done to the homework rather than the student doing the action. In contrast, choices B, C, and D are in active voice where the subject performs the action. B states "The student completed the homework," C states "The teacher is grading the papers," and D states "The store opens at 9 AM." These choices clearly show the subjects performing the actions, making them in active voice.

Correct Answer: A

Rationale: The correct answer is A: dilate. Eye drops that dilate the pupils are commonly used to prepare for eye exams as they cause the pupils to expand or open up. This allows more light to enter the eye and provides a better view of the back of the eye. Constrict (choice B) means to narrow or make smaller, which is the opposite effect needed for an eye exam. Enlarge (choice C) is incorrect as it means to make something larger, which is not the intended effect. Decrease (choice D) is also incorrect as it means to make something smaller, which is opposite of what is required for an eye exam.

Correct Answer: A

Rationale: The correct answer is A: of. The phrase "within 24 hours of administration" indicates a specific time frame after the administration of the tuberculin skin test. The preposition "of" in this context signifies the relationship between the time frame (24 hours) and the event (administration of the test). Using "before" (B), "after" (C), or "during" (D) would change the meaning of the sentence and imply a different timing relationship, which is not accurate in this context. Therefore, choice A is the correct preposition to use in this sentence.

Correct Answer: B

Rationale: The correct answer is B: Getting worse. When a patient's condition is deteriorating, it means their health is declining or worsening. This is often indicated by worsening symptoms or vital signs. The other choices are incorrect because: A: Improving - Opposite of deteriorating, indicates better health. C: Stabilizing - Indicates the condition is neither improving nor worsening. D: Reversing - Suggests a complete turnaround or improvement, not consistent with deterioration.
