Vocabulary HESI A2

Correct Answer: B

Rationale: The correct answer is B: High-spirited. Euphoric means feeling intense happiness or excitement. High-spirited aligns with this definition as it denotes a state of enthusiasm and joy. Disease-ridden (A) is incorrect as it describes being infected with a disease, not related to euphoria. Pretentious (C) means attempting to impress by affecting greater importance or talent than is actually possessed, which is not the meaning of euphoric. Understated (D) means presented or expressed in a subtle or restrained manner, which is the opposite of the vivid and intense emotion associated with euphoria.

Correct Answer: C

Rationale: The correct answer is C: obvious. An overt symptom is one that is easily observed or recognized, making it clear and apparent. It is not dangerous (A), as danger is a separate characteristic. It is not hidden (B) because overt symptoms are the opposite of being concealed or obscured. It is also not controlled (D) since controlled symptoms are actively managed or regulated, which is not the case for overt symptoms.

Correct Answer: B

Rationale: The correct answer is B: Inadvisable. In the sentence, "contraindicated" means not recommended due to potential harm. It is important to avoid aspirin in children with high fevers due to the risk of Reye's syndrome. The other choices are incorrect because: A: "Banned" implies a legal prohibition, which is not the case here. C: "Anticipated" means to expect or foresee, which doesn't fit the context. D: "Expedient" means convenient or practical, which is not relevant to the medical advice given in the sentence.

Correct Answer: C

Rationale: The correct answer is C: Postmortem. The word "posthumous" in the sentence refers to something occurring after death. In this context, a posthumous donation is a donation made after the donor's death. Therefore, the meaning of posthumous aligns with postmortem, which relates to things that occur after death. A: Generous - This choice does not accurately reflect the meaning of posthumous. While the donation may be generous, the key aspect is that it is made after the donor's death. B: Immense - This choice is unrelated to the meaning of posthumous. Immense refers to something extremely large or vast, which does not apply in this context. D: Time-honored - This choice is also unrelated to the meaning of posthumous. Time-honored refers to something respected or valued due to its longstanding tradition or history, which is not relevant to the context of a posthumous donation.

Correct Answer: B

Rationale: The correct answer is B: swollen. When a blood vessel is distended, it means it has expanded or become enlarged due to increased pressure or volume of blood. Swollen accurately describes this condition. Choice A, overturned, is unrelated to the expansion of a blood vessel. Choice C, twisted, implies a different type of deformation. Choice D, overlong, does not accurately describe the condition of distended blood vessels.
