the plumber used a flexible tube to open up the curved pipe

HESI A2

HESI A2 Practice Test Vocabulary

1. The plumber used a flexible tube to open up the curved pipe.

A. Solid
B. Rigid
C. Flexible
D. Perforated

Correct answer: C

Rationale: The term 'flexible' accurately describes the type of tube used in the given context. A 'solid' tube would not have been suitable for navigating a curved pipe as it is not pliable. 'Rigid' implies stiffness and inflexibility, making it unsuitable for the task. 'Perforated' means pierced with holes, which is unrelated to the plumber's task of opening up a curved pipe.

2. What is the best description for the abbreviation EEG?

A. A test of brain activity
B. A medical service
C. A heartbeat monitor
D. A specialist in dentistry

Correct answer: A

Rationale: The correct answer is A: 'A test of brain activity.' EEG stands for Electroencephalogram, a test used to evaluate the electrical activity in the brain. It helps diagnose conditions like epilepsy, seizures, and other brain disorders. Choice B, 'A medical service,' is too broad and does not specifically refer to EEG. Choice C, 'A heartbeat monitor,' is incorrect as EEG does not monitor the heart. Choice D, 'A specialist in dentistry,' is unrelated to the abbreviation EEG.

3. What does exogenous mean?

A. Produced within the body
B. Produced outside the body
C. A byproduct
D. Caused by bacteria

Correct answer: B

Rationale: Exogenous means produced outside the body. In this context, 'within the body' (Choice A), 'a byproduct' (Choice C), and 'caused by bacteria' (Choice D) do not accurately define exogenous. The correct definition of exogenous specifically refers to something originating or produced externally.

4. Which word describes a screen or filter?

A. Permeable
B. Incendiary
C. Exuding
D. Resilient

Correct answer: A

Rationale: The word 'permeable' refers to a material or surface that allows liquids, gases, or substances to pass through it, while screening or filtering out impurities. This makes it an appropriate descriptor for a screen or filter, which function by allowing certain elements to pass through while retaining others. Choices B, C, and D are incorrect: 'Incendiary' means causing fires, 'Exuding' means giving off or releasing, and 'Resilient' means able to withstand or recover from difficult conditions.

5. He has 3 DISCRETE symptoms, causing the doctor to create an elaborative plan of care.

A. individual
B. common
C. difficult
D. separate

Correct answer: D

Rationale: The term 'discrete' means individually separate and distinct. Therefore, the most appropriate choice to describe the symptoms that are distinct and separate from each other is 'separate' (option D). Choices A, B, and C are incorrect because they do not convey the specific meaning of the term 'discrete' as separate and distinct.
