HESI A2 Vocabulary Practice Test

Correct Answer: A

Rationale: The correct answer is A: Prefix. A prefix is a word part placed before a word to change its meaning. It modifies the root word's meaning. For example, adding "un-" before "happy" changes the meaning to "unhappy." Affix (B) is a broader term that includes both prefixes and suffixes. Suffix (C) is a word part placed after a word, and Vocab (D) stands for vocabulary, which is not directly related to changing the meaning of a word.

Correct Answer: B

Rationale: Step-by-step rationale: 1. "Precipitous" is often used to describe something happening quickly or suddenly. 2. The word "swift" means happening with speed and quickness. 3. Therefore, "swift" best aligns with the definition of "precipitous." Summary: - Choice A (Slow): Incorrect, as "slow" is the opposite of what "precipitous" typically means. - Choice C (Gradual): Incorrect, as "gradual" means happening slowly over time, opposite of "precipitous." - Choice D (Delayed): Incorrect, as "delayed" refers to something happening later than expected, not the suddenness of "precipitous."

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: 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.
