HESI A2 Vocabulary 2024

Correct Answer: D

Rationale: The correct answer is D: Composed. Unruffled means calm and composed, so the word "composed" is a synonym for unruffled. "Concerned" means worried or anxious, opposite of unruffled. "Wholesome" means healthy or good, unrelated to unruffled. "Tedious" means boring or monotonous, also unrelated to unruffled. Therefore, the best choice is "Composed" as it aligns with the meaning of unruffled.

Correct Answer: B

Rationale: The correct answer is B: parasite. A nit is a term used to refer to the egg or young form of a louse or other parasitic insect. Nits are commonly found in hair and are a common sign of a head lice infestation. Choice A (abscess) is incorrect because an abscess is a localized collection of pus caused by an infection. Choice C (bandage) is incorrect because a bandage is a material used to cover and protect wounds. Choice D (infection) is incorrect because an infection is a condition caused by the invasion of harmful microorganisms into the body. Therefore, the correct answer is B as nits specifically refer to parasites, such as lice eggs.

Correct Answer: A

Rationale: The correct answer is A: talus. The talus is the bone that forms the main connection between the foot and the leg, commonly known as the ankle bone. It articulates with the tibia and fibula to allow for ankle movement. The other choices, B: talon refers to an animal's claw, C: fascia is a connective tissue, and D: fascine is a bundle of sticks used in construction. Therefore, A is the correct answer as it specifically identifies the bone that is commonly referred to as the ankle bone.

Correct Answer: C

Rationale: The correct answer is C: clavicle. The clavicle is commonly known as the collarbone in anatomy. The clavicle is a long bone that connects the shoulder blade to the sternum. It is easily identifiable due to its S-shaped curve and plays a crucial role in shoulder movement and stability. Explanation: A: Cloaca - Cloaca is a term used in zoology to describe a common opening for the digestive, excretory, and reproductive systems in some animals. It is not related to the collarbone. B: Cannula - A cannula is a thin tube inserted into the body for medical purposes such as administering fluids or medications. It is not related to the collarbone. D: Clavier - Clavier refers to a keyboard musical instrument like a piano. It is not related to the collarbone.

Step 3: Understanding that the parietal bone is a cranial bone reinforces choice B as the correct answer. Summary: Choice A is incorrect as the partial bone does not exist in the cranial structure. Choice C, pariah, is unrelated to cranial anatomy. Choice D, parhelion, is not a cranial bone but a term referring to a bright spot beside the sun.
