HESI A2 Practice Vocabulary

1. What does 'Contour' mean?

A. Flat area
B. Shape or outline of something
C. Volume of a structure
D. Height of a structure

Correct answer: B

Rationale: The term 'Contour' specifically refers to the shape or outline of something. In art and geography, contours are used to represent the outline or shape of an object or landform, making choice B the correct definition. Choice A, 'Flat area,' is incorrect as it does not capture the essence of contour which is about the shape or outline. Choice C, 'Volume of a structure,' is unrelated to the concept of contour. Choice D, 'Height of a structure,' is also incorrect as contour is more about the shape and not the height of an object.

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

A. An online social network
B. A test for postgraduate students
C. A well-known pharmaceutical
D. A public health association

Correct answer: D

Rationale: The abbreviation CDC stands for the Centers for Disease Control and Prevention, which is a well-known public health association in the United States. The CDC is a federal agency under the Department of Health and Human Services, responsible for protecting public health and safety by controlling and preventing disease, injury, and disability. Choices A, B, and C are incorrect as they do not accurately describe what the CDC is known for; it is not an online social network, a test for postgraduate students, or a pharmaceutical company.

3. If a patient's condition is deteriorating, what is happening?

A. They are improving
B. They are getting worse
C. They are stable
D. They are recovering

Correct answer: B

Rationale: When a patient's condition is deteriorating, it means they are getting worse. This indicates a decline or worsening in their health status, requiring immediate attention or intervention. Choice A is incorrect because 'improving' means the opposite of deteriorating. Choice C is incorrect as 'stable' means there is no significant change. Choice D is incorrect as 'recovering' means getting better, which is the opposite of deteriorating.

4. What does 'abrupt' mean?

A. Gradual
B. Sudden
C. Delayed
D. Relaxed

Correct answer: B

Rationale: The correct answer is B: 'Sudden.' Abrupt means something that occurs suddenly, without warning or preparation. It is the opposite of gradual, delayed, or relaxed, which imply a slower or more gentle pace of change or action.

5. Which sentence is NOT GRAMMATICALLY CORRECT?

A. Because he did not examine the patient, the healthcare provider prescribed her with the wrong medication.
B. The nurse decided to bathe the client, then trim his nails.
C. The dietician, through negligence, made a mistake with the diet plan.
D. Since the child was feeling ill, the nurse sent him home.

Correct answer: B

Rationale: Choice B is incorrect due to the use of 'than' instead of 'then.' The correct word in this context is 'then' to indicate the order of actions. Choices A, C, and D are all grammatically correct. In choice A, the sentence structure is correct with a clear cause-effect relationship. Choice C is grammatically sound, describing the dietician's mistake. Choice D is also grammatically correct, showing a cause (the child feeling ill) leading to an effect (the nurse sending him home).
