HESI A2 Vocabulary 2023

Correct Answer: C

Rationale: The correct answer is C: Reaction. In the context of the sentence, 'reflex' refers to an involuntary and nearly instantaneous reaction to a stimulus. The patellar reflex mentioned involves the leg extension in response to a tap on the patellar tendon. Replication (A) does not fit the context as the sentence is not referring to duplicating something. Convulsion (B) implies a violent, involuntary contraction of muscles, which is not the focus here. Stretching (D) is not the correct choice as it does not capture the immediate and automatic nature of a reflex action.

Correct Answer: A

Rationale: The correct answer is A: eyelid. A stye, also known as a hordeolum, is an infection of the eyelid caused by bacteria. It typically forms near the base of the eyelash due to a blocked oil gland. Symptoms include redness, swelling, and pain. The other choices (B, C, D) are incorrect because a stye specifically affects the eyelid and not the eardrum, nostril, or scalp. Each of these areas has its own distinct conditions and infections unrelated to a stye.

Correct Answer: C

Rationale: The correct answer is C: Gums and teeth. When people masticate, they use their gums to hold the food in place and their teeth to break down the food into smaller pieces through chewing. This process is essential for digestion. Choices A, B, and D are incorrect because fingers, eyes, ears, heels, and toes are not involved in the mastication process.

Correct Answer: A

Rationale: The correct answer is A: Permeable. Permeable describes a screen or filter because it allows substances to pass through. Screens and filters are designed to allow certain particles or substances to flow through while blocking others. Choice B, Incendiary, is incorrect as it means causing fires. Choice C, Exuding, is incorrect as it means to discharge or emit. Choice D, Resilient, is incorrect as it means able to withstand or recover from difficult conditions. The key in this question is understanding the function of a screen or filter, which is to permit the passage of some substances while blocking others, making the term "permeable" the most appropriate choice.

Correct Answer: C

Rationale: The correct answer is C: full. Replete means filled or well-supplied with something. In this context, it refers to being completely full or satisfied. Choice A (hardy) does not convey the same meaning. Choice B (quiet) and choice D (sad) are unrelated to the definition of replete, making them incorrect. Therefore, C is the best fit as it directly aligns with the definition of the word.
