HESI A2 Practice Vocabulary
1. What is the process of digestion?
- A. Production of enzymes
- B. The mechanical and chemical breakdown of food
- C. Absorption of nutrients in the blood
- D. Movement of enzymes
Correct answer: B
Rationale: The correct answer is B: The mechanical and chemical breakdown of food. Digestion involves breaking down food mechanically and chemically into smaller components for absorption by the body. This process occurs in the digestive system, preparing nutrients for absorption in the intestines. Choices A, C, and D are incorrect because digestion is not solely about the production of enzymes, absorption of nutrients in the blood, or movement of enzymes; it primarily involves breaking down food for nutrient absorption.
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. Choose the meaning of the word intact in the following sentence: 'The capsule remains intact even when placed in water.'
- A. Viable
- B. Operational
- C. Tinted
- D. Whole
Correct answer: D
Rationale: In this sentence, the word 'intact' is synonymous with 'whole,' meaning that the capsule remains undamaged or complete even when placed in water. Choices A, B, and C are incorrect. 'Viable' means capable of working successfully, 'operational' means in working order, and 'tinted' means slightly colored.
4. Choose the meaning of the word 'waft' in the following sentence: The steady breeze caused dry leaves to waft over the creek.
- A. Sink
- B. Dive
- C. Wave
- D. Float
Correct answer: D
Rationale: In this sentence, the word 'waft' is used to describe the movement of dry leaves over the creek in response to the steady breeze. 'Waft' means to float gently through the air. The correct meaning of 'waft' in this context is to float. Choices A, B, and C are incorrect because 'sink' means to go down below the surface of something, 'dive' means to plunge headfirst into water or another substance, and 'wave' means to move one's hand to and fro in greeting or as a signal.
5. What does the term 'residual' refer to in the following sentence? The nurse was asked to record the residual urine in the patient's bladder.
- A. Measurement
- B. What is left
- C. Total volume
- D. Color and clarity
Correct answer: B
Rationale: The term 'residual' refers to what is left after the main part has been taken or used. In this context, 'residual urine' specifically means the urine that remains in the bladder after urination. Choices A, C, and D do not accurately capture the meaning of 'residual' in this sentence. 'Measurement' (A) is too general, 'Total volume' (C) does not specifically pertain to what remains, and 'Color and clarity' (D) is unrelated to the concept of what is left.
