All questions
Question 1
Each of the new medical assistants must have credentials verified by the human resources department.
- their
- his or her (correct answer)
- they're
- themselves
Explanation: This question tests pronoun-antecedent agreement, a fundamental grammar concept you'll encounter on the HESI exam. When you see questions about pronouns, focus on identifying what noun the pronoun refers to (its antecedent) and ensuring they match in number and person.
The antecedent here is "each of the new medical assistants." While "medical assistants" is plural, the subject is actually "each," which is a singular indefinite pronoun. This means you need a singular pronoun to maintain agreement.
Option B) "his or her" is correct because it provides singular pronouns that agree with the singular subject "each." This construction acknowledges that the medical assistants could be of any gender while maintaining grammatical correctness.
Option A) "their" is incorrect because it's a plural pronoun, creating a mismatch with the singular subject "each." This is a common error in everyday speech, but it's grammatically incorrect in formal writing.
Option C) "they're" is wrong for two reasons: it's the contraction for "they are" (not a possessive pronoun), and it's plural, which doesn't agree with "each."
Option D) "themselves" is incorrect because it's a reflexive pronoun that doesn't fit the sentence structure, and it's also plural.
Remember this pattern: indefinite pronouns like "each," "every," "either," and "neither" are always singular, even when followed by plural nouns. They require singular pronoun agreement. On the HESI, watch for sentences beginning with these words—they often test this agreement rule.
Question 2
The head nurse told the student that she had made an error on the patient's chart. What is the grammatical problem with this sentence?
- Incorrect pronoun case
- Lack of subject-verb agreement
- Vague pronoun reference (correct answer)
- Incorrect verb tense
Explanation: When analyzing sentence clarity, you need to examine whether pronouns clearly refer to specific nouns. In this sentence, "The head nurse told the student that she had made an error on the patient's chart," the pronoun "she" creates confusion because it could refer to either the head nurse or the student. This ambiguity makes it impossible to determine who actually made the error, which is a classic example of vague pronoun reference.
The correct answer is C because the sentence contains an unclear pronoun that doesn't have a definite antecedent. Both "head nurse" and "student" are feminine nouns that could logically be replaced by "she," creating the grammatical problem.
Looking at the other options: A is incorrect because "she" is in the proper subjective case as the subject of "had made." The pronoun case itself isn't wrong—it's just unclear which person it represents. B is incorrect because there's perfect subject-verb agreement throughout: "nurse told" (singular subject with singular verb) and "she had made" (singular subject with singular verb). D is incorrect because the verb tenses are appropriate and consistent—past tense "told" for the main action and past perfect "had made" to show the error occurred before the conversation.
To fix this sentence, you'd need to specify: "The head nurse told the student that the student had made an error" or "The head nurse told the student that the head nurse had made an error."
Study tip: When you see pronoun problems on grammar questions, always check if each pronoun clearly points to one specific noun—ambiguous pronouns are a common test trap.
Question 3
Which of the following sentences contains a pronoun error?
- The nursing staff held its weekly meeting in the conference room.
- The patient's family was grateful to the technician and him.
- Just between you and I, the new charting software is difficult to use. (correct answer)
- She is the nurse who administered the medication.
Explanation: When you encounter pronoun questions on the HESI exam, focus on two key areas: pronoun case (subject vs. object) and pronoun-antecedent agreement. These errors are among the most commonly tested grammar concepts.
The correct answer is C because it contains a classic pronoun case error. After the preposition "between," you need object pronouns, not subject pronouns. The phrase should be "between you and me," not "between you and I." Many people incorrectly think "I" always sounds more formal or correct, but prepositions like "between," "with," "for," and "to" require object pronouns (me, him, her, us, them).
Let's examine why the other options are correct: Option A properly uses "its" because "nursing staff" is treated as a singular collective noun, so the singular pronoun "its" agrees with it. Option B correctly uses the object pronoun "him" because it follows the preposition "to" - you wouldn't say "grateful to he," so "grateful to the technician and he" is equally wrong. Option D uses "who" correctly as a subject pronoun introducing the relative clause "who administered the medication."
To master pronoun case, use this simple test: remove the other person from compound phrases and see what sounds right. For example, "between I" sounds wrong by itself, confirming that "between you and I" is incorrect. This strategy works for most pronoun case questions you'll encounter on the HESI exam.
Question 4
If you are looking for the lead pharmacist, the person in the white coat is .
- him
- he (correct answer)
- himself
- his
Explanation: This question tests your understanding of pronoun case in predicate nominative constructions. When you encounter a sentence with a linking verb like "is," pay attention to whether the pronoun comes after the verb and renames the subject.
The sentence "the person in the white coat is " uses the linking verb "is" to connect the subject "person" with a pronoun that identifies who that person is. After linking verbs, you need a subject pronoun (nominative case) because the pronoun is renaming or identifying the subject, not receiving an action.
Choice B) "he" is correct because it's the nominative case pronoun that properly identifies "the person" as male. The complete sentence reads naturally: "the person in the white coat is he" (meaning "he is the person").
Choice A) "him" is incorrect because it's the objective case pronoun used for direct objects, indirect objects, or objects of prepositions. You wouldn't say "the person is him" in formal English.
Choice C) "himself" is wrong because it's a reflexive pronoun that refers back to the subject performing an action on itself. There's no reflexive action happening in this sentence.
Choice D) "his" is incorrect because it's a possessive pronoun showing ownership. The sentence isn't indicating that something belongs to someone; it's identifying who the person is.
Remember this pattern: after linking verbs (is, are, was, were, become, seem), use nominative pronouns (I, he, she, we, they) rather than objective ones (me, him, her, us, them). The pronoun test: flip the sentence to check if it makes sense as "He is the person."
Question 5
The new electronic health record system will directly affect healthcare providers in our network.
- we
- us (correct answer)
- our
- ourselves
Explanation: This question tests your understanding of pronoun cases, specifically when to use object pronouns versus subject pronouns. When you encounter pronoun questions, identify whether the pronoun functions as a subject (performing the action) or an object (receiving the action).
In this sentence, "The new electronic health record system will directly affect healthcare providers," the pronoun receives the action of the verb "affect." Since the pronoun is being acted upon (the system affects them), you need an object pronoun. "Us" (choice B) is the correct object pronoun form of "we."
Let's examine why the other options don't work. Choice A, "we," is a subject pronoun used when the pronoun performs an action (like "We implemented the system"), not when it receives action. Choice C, "our," is a possessive pronoun that shows ownership, but here the healthcare providers themselves are being affected, not something they possess. Choice D, "ourselves," is a reflexive pronoun used when the subject and object refer to the same entity performing an action on itself, which doesn't apply in this context.
To test your pronoun choice, try substituting a clearer noun phrase. You wouldn't say "The system will affect we healthcare providers" or "The system will affect ourselves healthcare providers." You would naturally say "The system will affect us healthcare providers."
Remember: Use subject pronouns (I, we, he, she, they) when the pronoun does the action, and object pronouns (me, us, him, her, them) when the pronoun receives the action.
Question 6
The responsibility for monitoring the patient's vital signs is now entirely .
- you
- your
- yours (correct answer)
- yourself
Explanation: This question tests your understanding of possessive pronouns in English grammar, which frequently appears on the HESI exam's language and grammar sections.
The sentence requires a possessive pronoun that can stand alone without being followed by a noun. When you see "entirely" followed by a blank at the end of a sentence, you need a pronoun that functions independently to show ownership or responsibility.
"Yours" (C) is correct because it's a possessive pronoun that stands alone. It clearly indicates that the responsibility belongs to you without needing to modify another noun. The sentence structure "The responsibility is now entirely yours" is grammatically complete and natural.
Let's examine why the other options don't work: (A) "you" is a personal pronoun, not possessive, so "entirely you" creates an incomplete, awkward construction. (B) "your" is a possessive adjective that must be followed by a noun (like "your responsibility"), but here it would leave the sentence hanging incomplete. (D) "yourself" is a reflexive pronoun used for emphasis or when the subject and object are the same person, but "entirely yourself" doesn't convey ownership of responsibility.
For HESI grammar questions, remember the key distinction between possessive adjectives (my, your, his, her, its, our, their) that modify nouns, and possessive pronouns (mine, yours, his, hers, its, ours, theirs) that stand alone. When you see a sentence ending with a possessive concept but no following noun, you'll need the standalone possessive pronoun form.
Question 7
Several of the physical therapists have updated certifications in sports medicine.
- his or her
- their (correct answer)
- its
- one's
Explanation: When you encounter pronoun agreement questions, you need to identify the antecedent (the noun the pronoun refers to) and match it in number and person. Here, the antecedent is "several of the physical therapists," which is clearly plural.
The correct answer is B) "their" because it's the plural possessive pronoun that agrees with the plural subject "several of the physical therapists." When multiple people possess something individually (each therapist has his or her own certification), "their" is the appropriate choice.
Let's examine why the other options fail: A) "his or her" is singular and doesn't match the plural antecedent. While this construction works for singular indefinite pronouns like "everyone," it's incorrect when referring to a clearly plural group. C) "its" is used for non-human entities and would be inappropriate when referring to people. D) "one's" is an indefinite possessive pronoun that doesn't logically connect to the specific group of physical therapists mentioned.
The sentence structure "several of [group]" creates a plural subject, even though it begins with "several of." Don't be misled by the prepositional phrase "of the physical therapists" – the subject remains plural.
For HESI grammar questions, always identify the true subject first, then ensure your pronoun matches in number (singular/plural) and person (first, second, third). When you see "several," "many," "few," or other plural quantifiers, the pronoun will almost always be plural as well.
Question 8
During the nursing orientation, the charge nurse emphasized the importance of clear communication when discussing patient care plans with colleagues and family members.
Which sentence contains a pronoun agreement error that could lead to miscommunication in a healthcare setting?
- Each nurse must ensure they document all medications administered to their assigned patients. (correct answer)
- The medical team reviewed the patient's chart before making their recommendations.
- Neither the physician nor the nurse practitioner shared their concerns with the family.
- Both nurses confirmed that they had completed the required safety checklist.
Explanation: Choice A contains a pronoun agreement error. 'Each nurse' is singular, but 'they' and 'their' are plural pronouns. The correct version should use 'he or she' and 'his or her' or be rewritten to avoid the issue. Choice B is correct because 'team' can take plural pronouns. Choice C is correct because with 'neither...nor,' the pronoun agrees with the closer noun (nurse practitioner). Choice D is correct because 'both nurses' is plural, matching 'they.'
Question 9
In the following sentence, which pronoun case correction is needed: 'Between you and I, the patient seems more comfortable when us nurses explain procedures thoroughly'?
- Change 'I' to 'me' and 'us nurses' to 'we nurses' to maintain proper objective and subjective case usage (correct answer)
- Change 'I' to 'me' only, since 'us nurses' functions correctly as the object of the preposition 'when'
- Change 'us nurses' to 'we nurses' only, since 'I' functions correctly as part of the compound object
- No changes needed, as both pronouns are in the correct case for their grammatical functions in context
Explanation: Both pronouns need correction. 'Between you and I' should be 'between you and me' because 'between' is a preposition requiring the objective case. 'Us nurses' should be 'we nurses' because it functions as the subject of the clause 'we nurses explain procedures.' Choice B incorrectly justifies 'us nurses.' Choice C incorrectly accepts 'I' after a preposition. Choice D incorrectly accepts both errors.
Question 10
The hospital's quality improvement committee was reviewing incident reports to identify patterns that could improve patient safety protocols.
Which revision correctly addresses the pronoun reference ambiguity in this sentence: 'When the nurse supervisor met with the staff member about the medication error, she emphasized the importance of double-checking dosages'?
- When the nurse supervisor met with the staff member about the medication error, the supervisor emphasized the importance of double-checking dosages. (correct answer)
- When the nurse supervisor met with the staff member about the medication error, she herself emphasized the importance of double-checking dosages.
- When the nurse supervisor met with the staff member about the medication error, her emphasis was on the importance of double-checking dosages.
- When the nurse supervisor met with the staff member about the medication error, they emphasized the importance of double-checking dosages.
Explanation: Choice A eliminates ambiguity by replacing the unclear pronoun 'she' with the specific noun 'the supervisor.' The original sentence is unclear because 'she' could refer to either the supervisor or the staff member. Choice B still contains ambiguity with 'she herself.' Choice C maintains the ambiguous 'her.' Choice D creates a new error by using plural 'they' for a singular antecedent.
Question 11
In the sentence 'The patient asked my preceptor and myself to explain who would be responsible for their care during the night shift,' what corrections are needed?
- Change 'myself' to 'I' to correct the improper reflexive pronoun usage in the compound subject construction
- Change 'myself' to 'me' since it functions as part of the compound object of the verb 'asked' in this context (correct answer)
- Change 'their' to 'his or her' to maintain singular agreement with 'patient' throughout the sentence structure
- Change both 'myself' to 'I' and 'their' to 'his or her' to correct subject-case and agreement errors simultaneously
Explanation: The sentence needs 'me' instead of 'myself' because 'my preceptor and me' functions as the compound object of 'asked.' Reflexive pronouns like 'myself' should only be used when referring back to the subject of the sentence. 'Their' is acceptable for singular 'patient' in modern usage for gender inclusivity. Choice A incorrectly suggests 'I' for an object position. Choice C unnecessarily changes the acceptable 'their.' Choice D makes the same error as A while unnecessarily changing 'their.'
Question 12
The infection control team was preparing a presentation about hand hygiene compliance rates for the monthly staff meeting.
Which sentence demonstrates the most appropriate pronoun usage for professional healthcare communication?
- Each department head should review their unit's compliance data and identify areas where they can improve infection prevention measures.
- Every department head should review his or her unit's compliance data and identify areas where he or she can improve infection prevention measures.
- Department heads should review their units' compliance data and identify areas where they can improve infection prevention measures. (correct answer)
- Each department head should review compliance data for their unit and identify areas where improvements in infection prevention measures are needed.
Explanation: Choice C uses the plural 'department heads' with matching plural pronouns 'their' and 'they,' creating clear, natural-sounding professional communication. Choice A mixes singular 'each department head' with plural pronouns, creating agreement issues. Choice B, while grammatically correct, sounds awkward and repetitive with 'his or her' and 'he or she.' Choice D mixes singular 'each department head' with plural 'their,' creating an agreement error.
Question 13
Analyze this sentence for pronoun case errors: 'The clinical instructor observed we students as us performed procedures, then asked my lab partner and I to demonstrate proper technique.' How should it be corrected?
- Change 'we students' to 'us students' and 'I' to 'me,' but keep 'us performed' since it refers to student actions
- Change 'us performed' to 'we performed' and 'I' to 'me,' but keep 'we students' as the object being observed
- Change 'we students' to 'us students' and 'us performed' to 'we performed,' but keep 'I' in the compound object
- Change 'us performed' to 'we performed' and 'I' to 'me,' and change 'we students' to 'us students' as the object (correct answer)
Explanation: Three corrections are needed: 'we students' should be 'us students' (object of 'observed'), 'us performed' should be 'we performed' (subject of the verb 'performed'), and 'I' should be 'me' (part of compound object of 'asked'). Choice A keeps the wrong subject pronoun 'us performed.' Choice B keeps the wrong object pronoun 'we students.' Choice C keeps the wrong object pronoun 'I.'
Question 14
In formal healthcare documentation, which sentence demonstrates correct pronoun case and agreement for professional standards?
- Neither the primary nurse nor the charge nurse completed their shift assessment documentation according to the established protocol requirements.
- Either the respiratory therapist or the nurses will adjust their treatment plan based on the patient's response to current interventions. (correct answer)
- Each member of the interdisciplinary team must ensure they submit their progress notes within the required timeframe for optimal patient care.
- The nurse manager told my colleague and I that us night shift workers needed to improve our documentation accuracy and timeliness.
Explanation: Choice B correctly uses 'their' because with 'either...or,' the pronoun agrees with the closer noun 'nurses' (plural). Choice A incorrectly uses 'their' with 'neither...nor' where both subjects are singular. Choice C mixes singular 'each member' with plural 'they' and 'their.' Choice D has two case errors: 'I' should be 'me' (object of 'told') and 'us night shift workers' should be 'we night shift workers' (subject complement).
Question 15
The hospital's ethics committee was reviewing a complex case involving patient autonomy and family decision-making authority.
Which sentence contains a pronoun reference error that could create confusion in the ethics committee's documentation?
- The ethics committee members discussed the case thoroughly before they reached their consensus about the appropriate course of action.
- The patient and his wife disagreed about the treatment plan, but he ultimately decided to proceed with the recommended surgery.
- After the family meeting, both the patient and his son felt confident that they had made the right decision together.
- When the patient's daughter spoke with the social worker about treatment options, she expressed concerns about the proposed intervention plan. (correct answer)
Explanation: Pronoun reference questions test whether you can identify unclear or ambiguous pronoun usage that could confuse readers. When pronouns like "he," "she," "it," or "they" appear in a sentence, they must clearly refer to a specific noun without creating confusion about which person or thing is being discussed.
In option D, the pronoun "she" creates ambiguity because it appears after mentioning both "the patient's daughter" and "the social worker" - two female individuals. Readers cannot definitively determine whether "she" refers to the daughter or the social worker who expressed concerns about the treatment plan. This ambiguity could lead to serious misunderstandings in medical documentation.
Option A correctly uses "they" and "their" to refer clearly back to "ethics committee members." Option B uses "he" unambiguously - while both the patient and his wife are mentioned, the pronoun clearly refers to "the patient" based on context and gender. Option C properly uses "they" to refer to both "the patient and his son," which is grammatically correct for a compound subject.
The correct answer is D because the pronoun reference error creates dangerous ambiguity in a healthcare context.
For HESI grammar questions, always check that pronouns have clear, unambiguous antecedents. When multiple people of the same gender appear in a sentence, look for potential confusion about which person a pronoun references. This is especially critical in healthcare writing where unclear documentation can impact patient care.
Question 16
The charge nurse and worked together to create the new staffing schedule for the unit.
- I (correct answer)
- me
- myself
- my
Explanation: This question tests your understanding of pronoun case in compound subjects. When you have two subjects connected by "and," each pronoun must be in the subject case because they're both performing the action of the verb.
The correct answer is A) "I" because it's the subject form of the first-person pronoun. In the sentence "The charge nurse and I worked together," both "the charge nurse" and "I" are subjects performing the action "worked." To check if you're using the right pronoun case, try removing the other subject: "I worked together to create the new staffing schedule" sounds correct, confirming that "I" is appropriate.
B) "me" is incorrect because it's the object form of the pronoun, used when something is being done to you rather than when you're doing the action. You wouldn't say "Me worked together," so it's wrong in the compound subject too.
C) "myself" is a reflexive pronoun that should only be used when you're both the subject and object of the action (like "I hurt myself") or for emphasis after already using "I." It's not appropriate in a simple compound subject.
D) "my" is a possessive pronoun showing ownership, not a subject pronoun. It would make the sentence grammatically incomplete since there would be no actual subject to perform the action.
Study tip: When dealing with compound subjects or objects, temporarily remove the other person from the sentence to test which pronoun sounds correct on its own. This simple trick will help you choose the right case every time.
Question 17
The specialist, to the complex case was referred, requested a complete patient history.
- who
- whomever
- whom (correct answer)
- whose
Explanation: When you encounter pronoun questions like this, you need to determine whether the pronoun is functioning as a subject or an object in the sentence. The key is to rearrange the sentence to see the pronoun's role more clearly.
Let's restructure this sentence: "The complex case was referred to ." Now you can see that the pronoun follows the preposition "to," which means it must be an object pronoun. When a pronoun serves as the object of a preposition, you always use the objective case.
The correct answer is (C) "whom" because it's the objective case of "who." The complete thought is "The specialist, to whom the complex case was referred, requested a complete patient history." The pronoun "whom" is the object of the preposition "to."
Here's why the other options don't work: (A) "who" is the subjective case, used when the pronoun is the subject performing an action, not receiving it. (B) "whomever" is also objective case, but it's used for indefinite references ("Give it to whomever you choose"), not for specific antecedents like "the specialist." (D) "whose" is the possessive form, indicating ownership, which doesn't fit the grammatical structure here.
Study tip: When you see "who/whom" questions, try substituting "he/him" in the rearranged sentence. If "him" sounds right, use "whom." If "he" fits better, use "who." This simple substitution test works because both pairs follow the same subject/object pattern.
Question 18
Please give the lab results to either Dr. Allen or as soon as they are available.
- I
- mine
- myself
- me (correct answer)
Explanation: This question tests your understanding of pronoun case, specifically when to use object pronouns versus subject pronouns in compound structures. When you encounter "either...or" constructions with pronouns, you need to determine whether the pronoun functions as a subject or object in the sentence.
The correct answer is (D) me because the pronoun serves as an indirect object in this sentence. The lab results are being given "to" someone, making both "Dr. Allen" and the pronoun recipients of the action. Since "me" is the object form of the first-person pronoun, it's grammatically correct here. You can test this by removing "Dr. Allen or" and reading the sentence: "Please give the lab results to me" sounds natural and correct.
(A) I is incorrect because "I" is a subject pronoun, not an object pronoun. You wouldn't say "give the lab results to I." (B) mine is wrong because it's a possessive pronoun showing ownership, not a pronoun that can receive an action. The sentence isn't about whose lab results they are. (C) myself is incorrect because reflexive pronouns like "myself" are used when the subject and object refer to the same person, or for emphasis. Here, the subject is an implied "you" (the person being asked to give the results), not "I."
Study tip: When choosing pronouns in compound structures with "and" or "or," temporarily remove the other person's name and read the sentence with just the pronoun. This helps you hear whether you need a subject pronoun (I, he, she, we, they) or object pronoun (me, him, her, us, them).
Question 19
The hospital is looking for a manager has experience with budget oversight and staff development.
- whom
- which
- who (correct answer)
- whose
Explanation: When you encounter pronoun questions on the HESI, you need to identify whether the pronoun serves as the subject or object of its clause, and whether it refers to a person or thing.
In this sentence, you're looking for a pronoun that introduces a relative clause describing "manager." The key is recognizing that this pronoun will be the subject of the clause "has experience with budget oversight and staff development." Since the pronoun performs the action "has," you need a subject pronoun.
Choice C) "who" is correct because it's the subject form of the relative pronoun used for people. The manager is a person, and "who" will be performing the action in the relative clause.
Choice A) "whom" is the object form of the relative pronoun for people. You'd use "whom" if the pronoun were receiving an action rather than performing one, such as "the manager whom we hired."
Choice B) "which" is used for things, not people. While grammatically it could function as a subject, it's inappropriate when referring to a person like a manager.
Choice D) "whose" indicates possession or ownership. You'd use this if the sentence were about something belonging to the manager, like "the manager whose department excels."
For HESI grammar questions, remember the "who/whom" test: if you can substitute "he/she" in the clause, use "who." If you can substitute "him/her," use "whom." Here, "he has experience" works perfectly, confirming that "who" is the right choice.
Question 20
The physician delegated the task of patient education to the resident and .
- she
- her (correct answer)
- herself
- hers
Explanation: This question tests your understanding of pronoun case, specifically when pronouns function as objects in a sentence. When you encounter pronoun questions, identify whether the pronoun is acting as a subject (doing the action) or an object (receiving the action or following a preposition).
In this sentence, the physician delegated the task "to the resident and ." The preposition "to" requires an object pronoun. The pronoun refers to another person who, along with the resident, will receive the delegated task. Since "the resident" and the pronoun are both objects of the preposition "to," you need the objective case pronoun "her."
You can test this by removing "the resident and" from the sentence: "The physician delegated the task to her" sounds correct, while "The physician delegated the task to she" clearly sounds wrong.
Looking at the wrong answers: A) "she" is a subject pronoun used when the pronoun performs the action, but here the pronoun receives the action. C) "herself" is a reflexive pronoun used when someone performs an action on themselves, which doesn't fit this context. D) "hers" is a possessive pronoun showing ownership, but nothing is being owned in this sentence.
Remember this pattern: after prepositions like "to," "with," "between," and "for," always use object pronouns (me, him, her, us, them). A quick test is to remove other people from the sentence and see if the pronoun alone sounds correct with the preposition.
