HESI A2 Practice Test Vocabulary
1. Which of the following is the plural form of the noun 'stimulus'?
- A. Stimulus
- B. Stimuli
- C. Stimulis
- D. Stimula
Correct answer: B
Rationale: The correct answer is 'Stimuli.' When forming the plural of 'stimulus,' the correct form is 'stimuli.' Choice A, 'Stimulus,' is the singular form, not the plural. Choice C, 'Stimulis,' is an incorrect spelling. Choice D, 'Stimula,' is also an incorrect form for the plural of 'stimulus.' Therefore, 'Stimuli' is the only correct plural form.
2. 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.
3. An enervated patient is ___________.
- A. anxious
- B. immature
- C. tired
- D. frightened
Correct answer: C
Rationale: Enervated refers to being weakened or lacking energy, so an enervated patient would likely be fatigued or tired. This term does not specifically imply anxiety, immaturity, or fear, making 'tired' the most suitable choice in this context. 'Anxious' (choice A) means feeling nervous or worried, which is not directly related to being enervated. 'Immature' (choice B) refers to lacking maturity or development, which is unrelated to the patient's energy level. 'Frightened' (choice D) means feeling afraid or scared, which is not necessarily connected to being enervated.
4. To STANCH a wound is to ____ it.
- A. Expand
- B. Restrict
- C. Release
- D. Avoid
Correct answer: B
Rationale: The correct answer is B: 'Restrict.' To stanch a wound means to stop or restrict the flow of blood. Choice A, 'Expand,' is incorrect as it means to make something larger. Choice C, 'Release,' is incorrect as it means to set something free. Choice D, 'Avoid,' is incorrect as it means to keep away or prevent something.
5. What does the term 'counterfeit' mean?
- A. Real
- B. Fake
- C. Accurate
- D. Honest
Correct answer: B
Rationale: The correct answer is B: 'Fake.' Counterfeit refers to something that is not genuine or a copy made to deceive. Choice A, 'Real,' is incorrect because counterfeit items are not real. Choice C, 'Accurate,' is incorrect as counterfeit implies inaccuracy. Choice D, 'Honest,' is incorrect as counterfeit items are deceptive and not honest.
