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: 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 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: his injury. Despite implies overcoming an obstacle, and an injury is a physical barrier that requires perseverance to conquer. Condition (B) is vague and could refer to various health issues. Pain (C) and fatigue (D) are temporary sensations, not necessarily significant enough to hinder completion of a race. Injury, on the other hand, suggests a more serious and ongoing challenge that would require determination to overcome.

Correct Answer: B

Rationale: The correct answer is B: Regretful. Contrite means feeling remorse or guilt for one's actions. It is important to differentiate between guilt and regret. Guilt implies responsibility for wrongdoing, while regret is feeling sorry for a past action. In this context, contrite aligns more closely with regretful as it signifies a sense of remorse without necessarily indicating guilt. Choices A, C, and D are incorrect as they do not capture the essence of contrite, which is about expressing sorrow and seeking forgiveness rather than feeling guilty, shameful, or pleased.
