Vocabulary HESI A2
1. What is the meaning of plastic?
- A. Mechanical
- B. Durable
- C. Authentic
- D. Flexible
Correct answer: D
Rationale: The correct answer is D: Flexible. Plastic is a material that can be easily molded or shaped, known for its flexibility. It can bend and stretch without breaking, making it versatile and durable. Choices A, B, and C are incorrect because plastic is not primarily associated with being mechanical, authentic, or durable, but rather with its ability to be shaped and its flexibility.
2. The doctor said he wanted to try other things before attempting an __________ procedure.
- A. Internal
- B. Painful
- C. Experimental
- D. Expensive
Correct answer: C
Rationale: The term 'invasive' refers to a procedure that involves entering the body, usually with a medical instrument or device. In the context provided, the doctor wants to try other non-invasive or less invasive options before resorting to an invasive procedure. 'Experimental' means untested or not yet proven to be effective, which aligns with the idea of exploring alternative methods before considering a more invasive approach. Choices A, B, and D are incorrect because they do not relate to the context of trying alternative procedures that are different from invasive ones.
3. If a patient is especially obdurate, she is ___________.
- A. very large
- B. quite stubborn
- C. easily upset
- D. ready to go home
Correct answer: B
Rationale: The correct answer is B: 'quite stubborn.' The word 'obdurate' means stubbornly refusing to change one's opinion or course of action. Therefore, if a patient is especially obdurate, it indicates that she is likely very stubborn in her behavior or beliefs. Choices A, C, and D are incorrect because they do not reflect the meaning of 'obdurate.' Being 'very large' (Choice A), 'easily upset' (Choice C), or 'ready to go home' (Choice D) does not directly relate to being stubborn and unwilling to change.
4. What does the term 'Precept' mean?
- A. A rule
- B. A guiding principle
- C. A habit
- D. A punishment
Correct answer: B
Rationale: The term 'Precept' refers to a guiding principle rather than just a rule, habit, or punishment. A precept is a general rule or principle guiding behavior, making choice B the correct answer. Choices A, C, and D are incorrect because a precept is more than just a simple rule, habit, or punishment; it encompasses a fundamental guiding principle that influences actions and decisions.
5. The ETIOLOGY of the flu epidemic of 1918 remains unknown to this day.
- A. Pathology
- B. Transmission
- C. Etiology
- D. Mortality rate
Correct answer: C
Rationale: The term 'etiology' refers to the cause or origins of a disease. In this context, the question is asking for the underlying reason or cause of the flu epidemic of 1918. Therefore, the correct answer is C. 'Etiology.' Choice A, 'Pathology,' is incorrect as it refers to the study of diseases rather than the cause itself. Choice B, 'Transmission,' is incorrect as it relates to how a disease spreads rather than its cause. Choice D, 'Mortality rate,' is incorrect as it refers to the number of deaths caused by a disease rather than the cause of the disease itself.
