Vocabulary HESI A2 Practice Test
1. What does 'Impending' mean?
- A. Likely to never occur
- B. Likely to occur soon
- C. Certain to never occur
- D. Unlikely to occur
Correct answer: B
Rationale: The correct answer is B: 'Likely to occur soon.' 'Impending' is used to describe something that is about to happen or is looming in the near future. Choices A, C, and D are incorrect because 'Impending' does not indicate that something is unlikely, certain to never occur, or likely to never occur.
2. What does 'Discrete' mean?
- A. Continuous
- B. Distinct or separate
- C. Mixed
- D. Combined
Correct answer: B
Rationale: The correct answer is B, 'Distinct or separate.' Discrete refers to something that is individually separate and distinct, not continuous (choice A), mixed (choice C), or combined (choice D). In mathematics and other fields, discrete items are countable and distinct from each other.
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 does Depth mean?
- A. The thickness of an object
- B. Downward measurement from a surface
- C. The length of a surface
- D. The area between two points
Correct answer: B
Rationale: Depth refers to the distance or downward measurement from a surface. It is not the thickness of an object (Choice A), as thickness is the measure of how thick or thin an object is, not necessarily related to depth. Additionally, it is not the length of a surface (Choice C) because length typically refers to the longest dimension of an object rather than its depth. Finally, it is not the area between two points (Choice D) because area is a measure of the space within a boundary defined by points, while depth specifically refers to the vertical distance below a surface.
5. What is the CORRECT CONTRACTION for 'They are'?
- A. Their
- B. They're
- C. The're
- D. No contraction used
Correct answer: B
Rationale: The correct contraction for 'They are' is 'They're.' 'Their' is a possessive pronoun indicating ownership, not a contraction. 'The're' is not a valid contraction. 'No contraction used' is incorrect as there is a contraction for 'They are,' which is 'They're.'
