HESI A2 Practice Vocabulary

1. What does 'Occluded' mean?

A. Open
B. Closed or obstructed
C. Partially obstructed
D. Expanded

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. The interns observed the CONTOURS of the patients' rash. What does Contours mean?

A. Color
B. Shape
C. Size
D. Texture

Correct answer: B

Rationale: The correct answer is B: 'Shape.' Contours refer to the outline or shape of something. In this context, the interns were observing the shape or outline of the patients' rash, not the color, size, or texture. Colors, sizes, and textures are not typically described as contours, making choices A, C, and D incorrect.

3. Choose the meaning of the word 'dilute' in the following sentence: 'Always dilute that medicine before administering it to a patient.'

A. Add water to
B. Reduce by half
C. Warm up
D. Decontaminate

Correct answer: A

Rationale: In this context, 'dilute' means to make the medicine less concentrated by adding water or another liquid. It is important to dilute certain medicines to ensure they are safe and effective for a patient's use. Choice B, 'Reduce by half,' is incorrect as diluting does not necessarily mean reducing by half; it means to make less concentrated. Choice C, 'Warm up,' is unrelated to the meaning of dilute. Choice D, 'Decontaminate,' is also incorrect as dilute refers to reducing the concentration of a substance, not removing contaminants.

4. What does bifurcate mean?

A. Fold twice
B. Flower biannually
C. Divide in two forks
D. Pierce two openings

Correct answer: C

Rationale: Bifurcate means to divide into two forks or branches. It comes from the Latin word "bi" meaning two and "furca" meaning fork. So, when something bifurcates, it splits into two separate paths or divisions. Choice A, "Fold twice," is incorrect as bifurcate doesn't involve folding. Choice B, "Flower biannually," is unrelated to the meaning of bifurcate. Choice D, "Pierce two openings," is also incorrect as it does not capture the true essence of bifurcate, which is about dividing into two forks or branches.

5. What does Gaping mean?

A. Partially closed
B. Wide open
C. Narrow
D. Sealed

Rationale: The correct answer is B, 'Wide open'. Gaping refers to something being wide open, not partially closed (choice A), narrow (choice C), or sealed (choice D). In the context of the question, 'Gaping' describes something that is open widely.
