HESI A2 Vocabulary 2024

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: Impoverished. 'Indigent' means poor or needy, lacking the necessities of life. In the context of the sentence, it refers to patients who are financially disadvantaged and unable to afford medical care. The other choices are incorrect because B: Resentful means feeling bitterness or indignation, C: Apathetic means showing no interest or concern, and D: Uninjured means not harmed physically. These options do not fit the context of accepting patients based on financial need.

Correct Answer: B

Rationale: The correct answer is B: Confirmed. Verified means to confirm the accuracy, truth, or validity of something. It involves ensuring that information or data is accurate and reliable. Belittled (A) means to make someone or something seem less important. Anecdotal (C) refers to personal accounts or stories that may not be verified. Implicit (D) means implied but not directly stated. Therefore, B is the correct answer as it aligns with the definition of verified.

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: Step 1: In a research study, a placebo is an inactive substance given to participants to compare the effects of the active treatment. Step 2: The purpose of a placebo is to serve as a control group for comparison with the group receiving the experimental drug. Step 3: Therefore, the meaning of 'placebo' in the sentence is 'control' as it is used for comparison purposes. Step 4: Choice A (Fallback) and D (Curative) do not accurately describe the role of a placebo in this context. Step 5: Choice B (Substitute) is not the best fit as the placebo is not substituting the actual treatment, but rather serving as a comparison point. Summary: The correct answer is C (Control) because a placebo is used as a comparison group in research studies, not as a fallback, substitute, or curative treatment.
