Vocabulary HESI A2
1. 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.
2. What action describes what a cat, who is clearly scared of a Rottweiler, will do when the dog enters the room?
- A. Cower
- B. Engender
- C. Enhance
- D. Replicate
Correct answer: A
Rationale: When a cat cowers, it means the cat is crouching down or trying to make itself look smaller in fear or apprehension of something, in this case, the Rottweiler. Hence, the word 'cower' accurately describes what the cat would do when faced with a Rottweiler entering the room. The other choices are incorrect: 'Engender' means to cause or give rise to, 'Enhance' means to improve or increase the quality or value of something, and 'Replicate' means to duplicate or reproduce something.
3. A body part that has atrophied has ______.
- A. Enlarged
- B. Withered
- C. Swollen
- D. Damaged
Correct answer: B
Rationale: The correct answer is 'Withered.' Atrophied means that a body part has wasted away or decreased in size. 'Enlarged' (Choice A) means to make or become larger, which is the opposite of atrophied. 'Swollen' (Choice C) means to become larger or rounder in size, usually due to fluid retention or inflammation, which is not the same as atrophied. 'Damaged' (Choice D) means harmed or injured, but it does not specifically refer to the wasting away or shrinking of a body part.
4. The electrolytes in human bodies include sodium, potassium, calcium, and ___________, among others.
- A. magnesium
- B. manganese
- C. magnetite
- D. manganite
Correct answer: A
Rationale: Magnesium is another essential electrolyte in the human body, along with sodium, potassium, and calcium. Magnesium plays a crucial role in various bodily functions, including muscle and nerve function, regulating blood pressure, and supporting the immune system. Manganese (Choice B), magnetite (Choice C), and manganite (Choice D) are not electrolytes found in the human body. Manganese is a mineral but not an electrolyte, while magnetite and manganite are compounds and not essential electrolytes for bodily functions.
5. If a theory is obsolete, what is true of it?
- A. Up to date
- B. Outdated
- C. Innovative
- D. Scientific
Correct answer: B
Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant. Choices A, C, and D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.
