HESI A2 Grammar Practice Exam

Correct Answer: A

Rationale: The correct answer is A: principle. In the sentence, the word should be "principal" to refer to the main or leading role. "Principle" refers to a fundamental truth or belief. The other choices, B: role, C: provision, and D: convenient are all spelled correctly and fit appropriately in the sentence context.

Correct Answer: B

Rationale: The correct punctuation needed in the sentence is a comma. A comma is used to separate two independent clauses when they are joined by a coordinating conjunction (such as "and" in this case). In the given sentence, "In addition to the hospital's regularly scheduled festivities" and "the custodians celebrate with a party of their own" are two independent clauses joined by "In addition to." Therefore, a comma is needed before the coordinating conjunction "In addition to" to make the sentence grammatically correct. Choice A (Period) is incorrect because a period would create two separate sentences, which is not the intended structure. Choice C (Apostrophe) is incorrect as there is no possessive form being used in the sentence. Choice D (Semicolon) is incorrect as a semicolon is not necessary to join these two independent clauses when a coordinating conjunction is present.

Correct Answer: C

Rationale: The correct answer is C: taking. In this sentence, "taking" is the present participle form and is used to show an ongoing action that occurred before the main action (patient sleeping). "Having taken" would imply the action of taking the pill occurred before the patient slept. The other choices are incorrect because: A: "took" is simple past tense, not fitting the structure of the sentence. B: "take" is the base form, not showing the correct tense or form. D: "taken" is the past participle form, but it doesn't convey the ongoing action needed in this context.

Correct Answer: C

Rationale: The correct answer is C: therapist. In this sentence, the word "therapist" is used incorrectly because it is redundant with the word "counselor." A therapist and a counselor are essentially the same role, providing emotional support and guidance. Therefore, using both terms in this context is unnecessary and redundant. The word "therapist" should be replaced with a different term, such as "doctor" or "psychologist," to convey a different role or specialization. The other choices (A, B, D) are used correctly in the sentence and do not present any errors in terms of grammar or meaning.

Correct Answer: D

Rationale: The correct answer is D: his. In this sentence, "Mr. Menotti's wife" indicates possession, meaning the belongings belong to Mr. Menotti. Therefore, the possessive pronoun "his" is the most appropriate choice to replace the underlined words. Choosing A (her) would imply the belongings belong to the wife, not Mr. Menotti. Using B (him) would suggest that the wife collected Mr. Menotti himself, not his belongings. Option C (he) is a subject pronoun and does not indicate possession, so it is not suitable in this context.
