HESI A2 Vocabulary Quiz

1. Choose the meaning of the word 'riddled' in the following sentence: 'The cavity, once opened, proved to be riddled with infection.'

A. Challenged
B. Overrun
C. Separated
D. Complete

Correct answer: B

Rationale: The word 'riddled' in this context means filled with or affected by (something undesirable) to a great degree, which aligns with the definition of 'overrun.' In this sentence, the cavity is described as being full of infection, indicating that the infection has spread extensively throughout. 'Challenged' (choice A) implies being tested or provoked, which is not the meaning conveyed by 'riddled.' 'Separated' (choice C) means divided or isolated, which does not fit the context of the sentence. 'Complete' (choice D) means finished or whole, which is the opposite of what is described in the sentence where the cavity is full of infection.

2. What is the best meaning of Pernicious?

A. Harmless
B. Destructive
C. Helpful
D. Harmful

Correct answer: B

Rationale: The correct answer is B, 'Destructive.' Pernicious is an adjective that describes something that is extremely harmful or destructive. Choice A, 'Harmless,' is the opposite of pernicious. Choice C, 'Helpful,' is a positive term and does not align with the meaning of pernicious. Choice D, 'Harmful,' is a similar term to pernicious but lacks the emphasis on the severe and damaging nature of the word.

3. A truculent patient is ______?

A. Passive
B. Argumentative
C. Cooperative
D. Friendly

Correct answer: B

Rationale: A truculent patient is characterized by being argumentative or hostile. Therefore, the correct answer is 'B: Argumentative.' Choices A, C, and D are incorrect because a truculent patient is not passive, cooperative, or friendly.

4. Select the meaning of the word 'residual' in the sentence. Something that remains is referred to as __________.

A. Resident
B. Residual
C. Resistance
D. Resin

Correct answer: B

Rationale: The correct answer is 'B: Residual.' In the given sentence, 'residual' is used to describe something that is left or remaining. 'Residual' fits the context perfectly as it aligns with the definition of what remains. The other choices are incorrect: A) 'Resident' refers to a person living in a specific place, C) 'Resistance' is the act of opposing or withstanding something, and D) 'Resin' is a sticky substance produced by plants.

5. Select the meaning of the underlined word in the following sentence. Apply the gel on the gingival margin around the selected teeth using the blunt-tipped applicator included in the package.

A. Edge
B. Grease
C. Incisor
D. Cavity

Correct answer: A

Rationale: In this context, the word 'margin' refers to the border or edge of the gums around the teeth. The gel is supposed to be applied on the gingival margin, which means on the edge or border of the gums near the selected teeth. Choice B, 'Grease,' is incorrect as it does not relate to the application of gel on the gums. Choice C, 'Incisor,' refers to a type of tooth and is unrelated to the context of applying gel on the gingival margin. Choice D, 'Cavity,' is also unrelated as it refers to a decayed area in a tooth and not the border of the gums.
