Vocabulary HESI A2 Practice Test

Correct Answer: B

Rationale: The correct answer is B: A tool or piece of equipment. A device is defined as a tool or piece of equipment designed for a specific purpose, such as a smartphone or a computer. This choice aligns with the general definition of a device and is the most accurate description among the options provided. A: An idea or concept is incorrect because a device is a physical object, not an abstract idea. C: A small part of a larger structure is incorrect because while a device can be a component of a larger system, it is not limited to being just a small part. D: An accessory for fashion is incorrect as a device is primarily functional and serves a specific purpose, not purely for fashion or aesthetics.

Correct Answer: C

Rationale: The correct answer is C: Flexible. A flexible tube would be most suitable for navigating through a curved pipe as it can bend and adapt to the shape of the pipe, allowing the plumber to maneuver easily. A solid tube (choice A) would not be able to bend, making it difficult to navigate through curves. A rigid tube (choice B) may also have difficulty navigating bends as it is not flexible. Perforated tubes (choice D) have holes and are not suitable for navigation through pipes. In summary, the flexibility of the tube is crucial for navigating through curved pipes efficiently.

Correct Answer: B

Rationale: The correct answer is B: Toward the midline. In anatomical terms, "medial" refers to a position closer to the midline of the body. This is the correct choice as it accurately describes the location in relation to the midline. Choices A, C, and D are incorrect because "Away from the midline," "At the side," and "Below the body" do not accurately define the term "medial" in anatomical language.

Correct Answer: A

Rationale: The correct answer is A: Complaining. Querulous means constantly complaining or irritable. Therefore, a patient who is querulous is likely to be guilty of complaining frequently. The other choices are incorrect because sleeping, shouting, or crying do not directly relate to the behavior of being querulous. Sleeping is unrelated, shouting is more about expressing anger or frustration, and crying is about showing emotion rather than complaining.

Correct Answer: B

Rationale: The correct answer is B: A guiding principle. A precept is a fundamental belief or rule guiding behavior. It is not simply a rule (choice A) but a broader guiding principle. It also does not refer to a habit (choice C) or a punishment (choice D), as precepts are more about moral or ethical guidance rather than behavioral patterns or penalties. Overall, the term 'precept' is best defined as a guiding principle due to its foundational and instructive nature.
