HESI A2 Vocabulary 2024

Correct Answer: C

Rationale: The correct answer is C: Autopsy. An inquest is a legal investigation to determine the cause of death, usually conducted by a coroner. In the sentence provided, the context of 'interesting discoveries' aligns with the purpose of an autopsy, where detailed examinations are carried out to uncover information related to the death. A: Tryout - Incorrect. A tryout refers to a trial or a test, which does not fit the context of making discoveries related to a death investigation. B: Intake - Incorrect. Intake refers to the process of taking something in, such as food or information, which does not match the context of conducting an investigation. D: Checkup - Incorrect. A checkup is a routine examination of a person's health, which is unrelated to the investigation of interesting discoveries as mentioned in the sentence.

Correct Answer: B

Rationale: Step 1: Identify the cranial bone that fits the blank. Step 2: Recall that the bone forming the top and sides of the skull is the parietal bone. 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.

Correct Answer: B

Rationale: The correct answer is B: Caesarean. The term "C-section" refers to Cesarean section, a surgical procedure to deliver a baby. The letter C is derived from the Latin word "Caesarean," named after Julius Caesar, who was rumored to have been born through this procedure. The other choices are incorrect because they do not have any relevance to childbirth or surgical procedures. Carthusian refers to a religious order, Cartesian is related to the philosopher Descartes, and Caedmon is an Anglo-Saxon poet. Therefore, the correct answer is B as it directly relates to the medical term being asked about.

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.

Correct Answer: C

Rationale: The correct answer is C: Evisceration. This term specifically refers to the surgical removal of an organ's contents. "Vivisection" (A) involves operating on live animals for scientific purposes. "Amputation" (B) is the removal of a limb. "Augmentation" (D) is the process of increasing the size or improving the function of an organ or body part. Evisceration is the only choice that directly pertains to the removal of an organ's contents, making it the correct answer.
