HESI A2 Practice Vocabulary

1. What does 'Occluded' mean?

Correct answer: B

Rationale: The term 'Occluded' means something is closed or obstructed, not open as in choice A. It is more than just partially obstructed as in choice C. It does not mean expanded as in choice D. Therefore, the correct answer is B, 'Closed or obstructed.'

2. Someone who is FRUSTRATED/ANNOYED is?

Correct answer: A

Rationale: The word 'exacerbated' means to make a problem, bad situation, or negative feeling worse. If someone is frustrated or annoyed, they are likely feeling worse due to a particular situation or circumstance. Choice B, 'transient,' means temporary or short-lived, which does not directly relate to the feeling of being frustrated or annoyed. Choice C, 'lithe,' means thin, supple, and graceful, which is not synonymous with being frustrated or annoyed. Choice D, 'terse,' means brief and to the point, which is unrelated to the context of feeling frustrated or annoyed.

3. What does 'Contour' mean?

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.

4. To alleviate a symptom is to ___________.

Correct answer: A

Rationale: The correct answer is A: 'relieve it.' To alleviate a symptom means to reduce or improve it, thus providing relief or easing of the discomfort or issue being experienced. Choice B, 'diagnose it,' is incorrect as diagnosing a symptom involves identifying or determining its cause, not relieving it. Choice C, 'suffer from it,' is incorrect as it refers to experiencing the symptom, not alleviating it. Choice D, 'manage it,' is incorrect as managing a symptom involves controlling or handling it, not necessarily reducing or relieving it.

5. What is the best description for the abbreviation LDL?

Correct answer: B

Rationale: The correct answer is B: A type of lipoprotein. LDL stands for Low-density lipoprotein, which is a type of lipoprotein that carries cholesterol through the bloodstream. LDL is often referred to as 'bad' cholesterol because high levels of LDL can lead to plaque buildup in the arteries, increasing the risk of heart disease and stroke. Choices A, C, and D are incorrect as they do not accurately describe the abbreviation LDL.
