HESI A2 Practice Vocabulary
1. Which sentence contains a subject-verb agreement error?
- A. The group of students is very smart
- B. The team of players is winning
- C. The list of items is on the table
- D. The pile of books is heavy
Correct answer: B
Rationale: The correct answer is 'B: The team of players is winning.' The error in this sentence is a subject-verb agreement issue. 'Team' is a singular noun, so it should take a singular verb 'is' instead of 'are.' The subject-verb agreement rule states that singular subjects should be paired with singular verbs, while plural subjects should be paired with plural verbs. Choices A, C, and D all demonstrate correct subject-verb agreement as they correctly match singular subjects ('group,' 'list,' 'pile') with singular verbs ('is,' 'is,' 'is').
2. What is the best description for the abbreviation EEG?
- A. A test of brain activity
- B. A medical service
- C. A heartbeat monitor
- D. A specialist in dentistry
Correct answer: A
Rationale: The correct answer is A: 'A test of brain activity.' EEG stands for Electroencephalogram, a test used to evaluate the electrical activity in the brain. It helps diagnose conditions like epilepsy, seizures, and other brain disorders. Choice B, 'A medical service,' is too broad and does not specifically refer to EEG. Choice C, 'A heartbeat monitor,' is incorrect as EEG does not monitor the heart. Choice D, 'A specialist in dentistry,' is unrelated to the abbreviation EEG.
3. Select the meaning of the underlined word in the following sentence. The patient will need to undergo additional testing.
- A. Fail
- B. Offer
- C. Experience
- D. Succumb
Correct answer: C
Rationale: In this context, the word 'undergo' means to experience or go through a process. When someone undergoes something, it implies they are subjected to it or experiencing it. Therefore, in the sentence provided, 'experience' is the correct meaning. Choices A, B, and D are incorrect as they do not align with the idea of going through a process or experiencing something.
4. Pulse, temperature, and respiration are known as ___________.
- A. vital signs
- B. vital statistics
- C. vital force
- D. vital capacity
Correct answer: A
Rationale: Pulse, temperature, and respiration are collectively known as vital signs. These measurements provide important information about a person's overall health status and are essential in assessing a person's well-being in various medical settings. Choice B, 'vital statistics,' is incorrect as vital statistics usually refer to data related to births, deaths, marriages, and health. Choice C, 'vital force,' is incorrect as it refers to a concept in some alternative medicine practices and is not a standard medical term for these measurements. Choice D, 'vital capacity,' is incorrect as it specifically refers to the maximum amount of air a person can expel from the lungs after a maximum inhalation, not a combination of pulse, temperature, and respiration.
5. A person who is ravenous is:
- A. generous
- B. outspoken
- C. friendly
- D. hungry
Correct answer: D
Rationale: The correct answer is D: "hungry." The term 'ravenous' specifically refers to being extremely hungry or famished. Choices A, B, and C are incorrect because they do not accurately reflect the meaning of 'ravenous.' Being generous, outspoken, or friendly does not directly relate to the intense hunger implied by the word 'ravenous.'
