HESI A2 Vocabulary 2024

Correct Answer: D

Rationale: The correct answer is D: recurring. A chronic condition is one that persists over a long period of time or reoccurs frequently. This term specifically refers to a condition that is ongoing or repetitive in nature. A: harmless - This choice does not describe the duration or frequency of the condition, only that it is not harmful. B: critical - This choice implies the condition is severe or urgent, which is not necessarily the defining characteristic of a chronic condition. C: contagious - This choice refers to the ability of a condition to spread from person to person, which is not related to the duration or frequency of the condition.

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: D

Rationale: The correct answer is D: Wrap. In the context of the sentence, "swathe" is used to indicate covering or wrapping the baby. The word is often associated with wrapping something in fabric or material. The other choices - Nurse, Cleanse, Change - do not align with the action of covering or wrapping the baby as described in the sentence. "Nurse" refers to caring for someone, "Cleanse" means to clean or purify, and "Change" implies altering or replacing something, none of which fit the context of the sentence. Therefore, option D is the most appropriate choice as it accurately reflects the meaning of 'swathe' in this context.

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.

Correct Answer: B

Rationale: The correct answer is B: Into muscles. 'Intramuscularly' refers to the administration of a substance directly into the muscle tissue. In the context of the sentence, it indicates how the vaccine should be used. Choice A (Between muscles) is incorrect as it does not accurately reflect the meaning of 'intramuscularly.' Choice C (Without muscles) is incorrect as it is the opposite of the intended meaning. Choice D (On top of muscles) is also incorrect as it does not involve penetration into the muscle tissue. Therefore, the correct choice is B because it best aligns with the definition of 'intramuscularly.'
