HESI A2 Vocabulary 2023
1. Select the meaning of the word 'reflex' in the sentence: 'The typical patellar reflex takes only 50 milliseconds between the initial tap and the leg extension.'
- A. Replication
- B. Convulsion
- C. Reaction
- D. Stretching
Correct answer: C
Rationale: In the context of the sentence, the word 'reflex' indicates a quick, automatic response by the body to a stimulus. The patellar reflex, also known as the knee-jerk reflex, involves the leg extending in response to a tap on the patellar tendon. Therefore, the word 'reaction' aligns closely with the nature of the patellar reflex in terms of a rapid and involuntary response. Choices A, B, and D are incorrect: 'Replication' does not capture the concept of a bodily response, 'convulsion' implies a sudden and uncontrollable movement which is not specific to the nature of the patellar reflex, and 'stretching' does not encompass the automatic and rapid nature of a reflex action.
2. What is another word for compendium?
- A. Collection
- B. Aptitude
- C. Conclusion
- D. Humor
Correct answer: A
Rationale: A compendium is a collection of concise but comprehensive information on a particular subject. Therefore, another word for compendium is "collection." The term "aptitude" refers to a natural ability to do something, not synonymous with compendium. "Conclusion" is a decision or judgment reached after considering the facts, not related to a compendium. "Humor" refers to the quality of being amusing or comic, not a synonym for compendium.
3. What is the meaning of the word 'placebo' in the following sentence: 'Ten patients will receive the experimental drug while 10 take a placebo'?
- A. Fallback
- B. Substitute
- C. Control
- D. Curative
Correct answer: C
Rationale: In the context of the sentence, the word 'placebo' refers to a substance or treatment that resembles a real medical treatment but has no therapeutic effect. It is used as a standard against which the effects of the experimental drug are compared. A placebo is typically included in a control group in medical research to evaluate the actual effects of the experimental drug. Therefore, in this scenario, the placebo serves as a control to gauge the effectiveness of the experimental drug, making choice C the correct answer. Choices A, B, and D are incorrect because a placebo is not a fallback, substitute, or curative treatment in this context.
4. Which sentence correctly uses a semicolon?
- A. I have a big test tomorrow; I can't go out tonight.
- B. She likes apples; oranges are her favorite.
- C. I went to the store; and I bought some milk.
- D. I like apples, but oranges are better.
Correct answer: B
Rationale: The sentence 'She likes apples; oranges are her favorite.' correctly uses a semicolon to connect two related independent clauses. The semicolon is used to separate two closely related ideas in a way that is stronger than a comma but not as final as a period. Choice A is incorrect because the conjunction 'but' is missing before 'I can't go out tonight.' Choice C is incorrect as the conjunction 'and' after the semicolon is unnecessary and disrupts the flow of the sentence. Choice D is incorrect because the semicolon is incorrectly placed before 'oranges are better,' where a comma or period would be more appropriate.
5. If a patient’s condition is deteriorating, he is ___________.
- A. getting worse
- B. improving gradually
- C. resisting medication
- D. failing to eat or drink
Correct answer: A
Rationale: When a patient's condition is deteriorating, it means that their health is declining or worsening. This can involve a range of factors such as worsening symptoms, declining vital signs, or an overall decline in health status. In this context, the phrase 'getting worse' best describes the situation of a patient whose condition is deteriorating. Choices B, C, and D are incorrect because they do not reflect the concept of deterioration in a patient's health. Improving gradually (choice B) indicates a positive trend, resisting medication (choice C) suggests a behavioral response, and failing to eat or drink (choice D) points to a specific issue rather than a general decline in health.
