HESI A2 Vocabulary Practice Test

Correct Answer: A

Rationale: The correct answer is A: Breathe. In this context, the child with a stuffy nose would find it hard to perform the action of breathing due to nasal congestion. "Breathe" is the correct verb form that indicates the act of inhaling and exhaling. The other choices are incorrect: B: Breathing is a noun form, C: Breath is a noun form, and D: Breadth refers to the extent or measure of something, none of which fit the context of the sentence. Thus, the correct answer is A as it accurately describes the difficulty the child would face due to a stuffy nose.

Correct Answer: B

Rationale: The correct answer is B: A deficiency or lack of something. 'Deficit' refers to a shortage or insufficiency of a particular quantity or quality. It is the opposite of an excess (choice A), abundance (choice C), or a stable amount (choice D). The term 'deficit' specifically implies a lack or inadequacy in comparison to what is required or expected.

Correct Answer: A

Rationale: The correct answer is A: graduated. In this sentence, "after she" indicates a future event, so the correct verb form should be future tense. "Graduated" is the only choice that correctly uses future tense and fits grammatically. Choices B, C, and D are all in past or present tenses, which do not align with the future context of the sentence. Therefore, A is the correct choice.

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. "became" is the correct verb form to use in this sentence because it is in the past tense and matches the timing of the action described. "Become" (choice A) is in the present tense and does not fit the past context of the sentence. "Been" (choice C) is a past participle form and does not work as the main verb in this sentence. "Had become" (choice D) is in the past perfect tense and is not necessary in this sentence as the simple past tense "became" is sufficient to convey the meaning.
