Quizlet Vocabulary HESI A2
1. What is a Nutrient?
- A. A chemical compound
- B. A substance that provides nourishment
- C. A non-essential mineral
- D. An essential vitamin
Correct answer: B
Rationale: A nutrient is a substance that provides nourishment to the body, such as carbohydrates, proteins, fats, vitamins, and minerals. Choice A has been improved to 'A chemical compound' to be more specific. Choice A is incorrect as it is too general and does not specifically describe the role of a nutrient. Choice C is incorrect as it focuses on minerals without specifying that all minerals are nutrients. Choice D is also incorrect as it solely emphasizes vitamins, which are just one type of nutrient.
2. What does 'Aggregate' mean?
- A. A part of the whole
- B. A sum total of many things
- C. A small fraction
- D. A gradual reduction
Correct answer: B
Rationale: The correct answer is B: 'A sum total of many things.' Aggregate refers to the total or sum of different elements or components. Choice A, 'A part of the whole,' is incorrect as aggregate does not refer to just a part but the whole combined. Choice C, 'A small fraction,' is incorrect as aggregate denotes a larger amount, not a small fraction. Choice D, 'A gradual reduction,' is incorrect as aggregate does not imply reduction but rather accumulation or combination.
3. Based on the principles of asepsis, the nurse should consider a sterile packet below waist level to be _____.
- A. contaminated
- B. sterilized
- C. clean
- D. untouched
Correct answer: A
Rationale: In aseptic techniques, maintaining the sterility of items is crucial. Placing a sterile packet below waist level exposes it to potential contamination from non-sterile surfaces or objects. Therefore, the correct term to describe the sterile packet in this situation is 'contaminated.' 'Sterilized' (choice B) is incorrect as it implies the packet has undergone a sterilization process, which may not be the case if it is now considered contaminated. 'Clean' (choice C) is incorrect because although the packet was initially sterile, placing it below waist level compromises its cleanliness. 'Untouched' (choice D) is incorrect as the packet has been touched or exposed to non-sterile areas, leading to potential contamination.
4. What is another word for toxin?
- A. Impurity
- B. Element
- C. Remedy
- D. Poison
Correct answer: D
Rationale: The correct answer is D, Poison. A toxin is a harmful substance that can cause illness or death, and poison is a synonym commonly used to refer to such substances. Choices A, B, and C are incorrect because impurity refers to something being dirty or unclean, an element is a pure substance that cannot be broken down further, and a remedy is a solution or treatment for a problem, not a harmful substance like a toxin.
5. What is another word for acrid?
- A. Bitter
- B. Smoky
- C. Nimble
- D. Severe
Correct answer: A
Rationale: Acrid is often used to describe a sharp, unpleasant smell or taste, which is synonymous with bitterness. The word 'bitter' closely relates to the strong and sharp sensation associated with acrid qualities. Choice B, 'Smoky,' does not capture the sharpness or unpleasantness associated with acrid, as it refers more to the presence of smoke. Choice C, 'Nimble,' and choice D, 'Severe,' are unrelated to the meaning of acrid and do not serve as synonyms in this context.
