HESI A2 Elsevier (HESI): HESI Admission Assessment - Set 2 - Part 3

Correct Answer: Sentence 4

Sentence 4 correctly uses a comma before the coordinating conjunction and that joins two independent clauses, following the standard rule for compound sentences. Each independent clause has its own subject and verb in this construction. Option a is incorrect because Sentence 1 inserts a comma between the subject and the compound predicate, which violates the rule against separating a subject from its verb with a comma. Subjects and verbs should not be split by commas. Option b is incorrect because Sentence 2 places a comma between the verb gathered and its object the supplies. A comma must not separate a verb from its noun. This kind of comma error is called comma intrusion. Option c is incorrect because Sentence 3 surrounds the conjunction and with commas, which is incorrect. Coordinating conjunctions joining elements take a single comma before them, not on both sides. Extra commas around the conjunction also disrupt the sentence flow.

Correct Answer: Sentence 3

Sentence 3 correctly uses a semicolon to join two closely related independent clauses without a coordinating conjunction. Both sides are complete sentences that could stand alone. Semicolons signal a closer relationship than a period. Option a is incorrect because Sentence 1 places a semicolon before the coordinating conjunction but. A coordinating conjunction takes a comma, not a semicolon, when joining two independent clauses. Semicolons are reserved for clauses without an explicit connector. Option b is incorrect because Sentence 2 uses however after the semicolon but omits the required comma. Conjunctive adverbs need a semicolon before and a comma after them between clauses. The transitional adverb however always needs both punctuation marks here. Option d is incorrect because Sentence 4 uses only a comma between two independent clauses, which is a comma splice. A semicolon, period, or coordinating conjunction is needed to fix it. Two clauses cannot share only a single comma.

Correct Answer: Sentence 1

Sentence 1 correctly uses a colon after a complete independent clause to introduce a list. The phrase the following signals the items that follow the colon. The clause before the colon is a complete sentence. Option b is incorrect because Sentence 2 places the colon directly after the verb prepared. A colon should follow a complete clause, not interrupt the link between a verb and its objects. The clause before a colon must be complete. Option c is incorrect because Sentence 3 splits the subject from the verb with a colon, which is never correct. A colon must follow a complete clause, not split subject from verb. The colon here disconnects subject from predicate. Option d is incorrect because Sentence 4 scatters punctuation throughout the sentence, including a misplaced colon and a stray comma after and. None of these marks follow standard list-introduction rules. Multiple errors break the sentence into a confused, ungrammatical pattern.

Correct Answer: nurses' uniforms

Nurses' uniforms is correct because it shows that uniforms belong to multiple nurses. Plural nouns ending in s take only an apostrophe after the s for possession. The placement signals shared ownership. Option a is incorrect because Nurses uniforms has no apostrophe, so it does not show possession. Plural possessives require an apostrophe, and without one the form is simply two nouns side by side. Possession requires an apostrophe somewhere. Option c is incorrect because Nurse's uniforms is the singular possessive, indicating uniforms belonging to one nurse. The sentence implies more than one nurse, so the plural possessive form is needed. The apostrophe before s makes this singular. Option d is incorrect because Nurses's uniforms uses both an s before the apostrophe and an s after it, which is not standard. Plural nouns ending in s receive only an apostrophe. English does not double the possessive marker.

Correct Answer: Sentence 4

Sentence 4 correctly contracts it is to It's and forms the singular possessive patient's with apostrophe before s. Both apostrophes serve their proper grammatical roles here. The contraction and possessive each follow the standard rule. Option a is incorrect because Sentence 1 uses its with no apostrophe and treats patients as a possessive without one. Both errors break the rule for contractions and singular possessive nouns. The contraction it is requires an apostrophe. Option b is incorrect because Sentence 2 adds an apostrophe to medications, which is plural and not possessive. Apostrophes do not form plural nouns, so medication's is incorrect in this position. The plural form should appear without any apostrophe. Option c is incorrect because Sentence 3 omits the apostrophe in It's, which should be the contraction of it is. Without the apostrophe, its becomes the possessive pronoun, changing the meaning so the sentence no longer makes sense.

Correct Answer: Sentence 3

Sentence 3 correctly uses she, the subjective form, because the pronoun joins the doctor as a co-subject of the verb reviewed. Subject pronouns belong before the verb. Compound subjects require subjective case for the pronoun. Option a is incorrect because Sentence 1 uses the objective her as a subject, which is wrong, and inserts an unnecessary comma between the subject and verb. Both errors break standard structure. Pronouns sharing a subject role take subjective case. Option b is incorrect because Sentence 2 still uses the objective her as part of the subject. A subject pronoun is required when the pronoun shares the action of reviewed. The objective her does not serve as a subject. Option d is incorrect because Sentence 4 places her, the objective form, in the subject position. The subjective form she is required, and the order is also less natural in formal writing. Convention places the third person second courteously.

Correct Answer: Sentence 1

Sentence 1 correctly pairs each with the singular has and uses his or her to maintain singular agreement. This is the traditional, formally correct construction tested on standardized exams. Each governs verb and pronoun consistently. Option b is incorrect because Sentence 2 uses the plural verb have with the singular indefinite pronoun each. Each always takes a singular verb, so have is incorrect in the standard test rule. The plural their compounds the agreement error. Option c is incorrect because Sentence 3 uses the plural have with the singular each, breaking subject-verb agreement. Even though his is singular, the verb error remains and makes the sentence wrong. Verb and pronoun agreement must follow each. Option d is incorrect because Sentence 4 uses the singular has correctly but pairs it with the plural pronoun their. Traditional grammar requires a singular pronoun after each, such as his or her. The pronoun must match the singular subject.

Correct Answer: Sentence 2

Sentence 2 correctly pairs the singular collective noun committee with the singular verb disagrees and uses the proper preposition about. The structure follows standard agreement rules. Collective nouns as one body take singular verbs. Option a is incorrect because Sentence 1 pairs the singular collective noun committee with the plural verb disagree. When a collective noun acts as one unit, it takes a singular verb. Standard formal grammar treats committee as singular. Option c is incorrect because Sentence 3 uses the plural verb are disagreeing with the singular committee and omits the preposition about, leaving the verb dangling without proper grammatical attachment. Both errors produce a sentence that fails standard grammar. Option d is incorrect because Sentence 4 uses the plural verb disagree with the singular committee and removes the required preposition about. Two errors prevent this sentence from being grammatically correct. It mismatches the verb and lacks the connector.

Correct Answer: Sentence 4

Sentence 4 correctly uses lay, the past tense of the intransitive verb lie, meaning to recline. No direct object is needed, and the past tense matches ate. The verbs lie, lay, lain follow this pattern. Option a is incorrect because Sentence 1 uses laid, the past tense of the transitive verb lay, which requires a direct object. The intransitive past tense for reclining is lay, not laid. This verb pair is among the most confused. Option b is incorrect because Sentence 2 uses eat, a present tense base form, after the past time marker after. The verb should be the past tense ate to match the time frame. Both verbs must agree in tense here. Option c is incorrect because Sentence 3 uses laid incorrectly, just like Sentence 1. The verb for reclining oneself in the past is lay, not laid, regardless of the adverb quickly. The added word does not change the verb form.

Correct Answer: Sentence 3

Sentence 3 correctly uses me as the object of the preposition between and inserts a comma after the introductory prepositional phrase, separating it from the main clause. Both grammar and punctuation conventions are satisfied here. Option a is incorrect because Sentence 1 uses I after the preposition between, but prepositions require objective pronouns. The correct objective form to follow between is me, not the subjective I. Hypercorrection often produces this error in formal writing. Option b is incorrect because Sentence 2 uses the correct objective me but omits the comma after the introductory prepositional phrase. A comma is placed after such a phrase before the main clause. Punctuation completes the sentence too. Option d is incorrect because Sentence 4 uses the reflexive yourself with no antecedent and the subjective I after a preposition. Both choices break standard grammar rules for pronoun case and use. Reflexives require an antecedent within the clause.
