HESI A2
Vocabulary for HESI A2
1. The doctor said he wanted to try other things before attempting an __________ procedure.
- A. Internal
- B. Painful
- C. Experimental
- D. Expensive
Correct answer: C
Rationale: The term 'invasive' refers to a procedure that involves entering the body, usually with a medical instrument or device. In the context provided, the doctor wants to try other non-invasive or less invasive options before resorting to an invasive procedure. 'Experimental' means untested or not yet proven to be effective, which aligns with the idea of exploring alternative methods before considering a more invasive approach. Choices A, B, and D are incorrect because they do not relate to the context of trying alternative procedures that are different from invasive ones.
2. 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.
3. Which term refers to the surgical removal of an organ's contents?
- A. Vivisection
- B. Amputation
- C. Evisceration
- D. Augmentation
Correct answer: C
Rationale: The correct answer is C, 'Evisceration.' Evisceration specifically refers to the surgical removal of an organ's contents, for example, the removal of abdominal contents during certain surgical procedures. Vivisection (A) involves performing experiments on live animals, amputation (B) is the removal of a limb, and augmentation (D) is the process of increasing the size, value, or quality of something. Therefore, in the context of surgical procedures, evisceration best fits the description of removing an organ's contents.
4. Select the meaning of the following phrase. 'A system of procedures to follow.'
- A. Regimen
- B. Regime
- C. Testament
- D. Treatment
Correct answer: A
Rationale: The correct answer is 'Regimen.' 'Regimen' refers to a prescribed set of procedures or a routine, especially related to health. Choice B, 'Regime,' typically refers to a system of government or a ruling period. Choice C, 'Testament,' means a person's will or a statement of belief. Choice D, 'Treatment,' is a medical care given to a patient.
5. 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.
