Vocabulary HESI A2

Correct Answer: D

Rationale: The correct answer is D: Poison. A toxin is a poisonous substance produced within living cells or organisms. "Impurity" (A) refers to something that is not pure, not necessarily toxic. "Element" (B) refers to a substance that cannot be broken down into simpler substances, not specifically toxic. "Remedy" (C) is a substance used to cure or relieve a disease, not toxic. Therefore, the best synonym for toxin is "Poison" as it specifically denotes a substance that is harmful and can cause illness or death.

Correct Answer: C

Rationale: The correct answer is C: Responsible. In the sentence, "accountable" implies being responsible for something, in this case, the records.

A: Receptive - This word means being open or responsive to new ideas, suggestions, or information. It does not fit the context of being responsible for records. B: Notorious - This word means well-known for a negative reason. It does not relate to the sense of responsibility or accountability.

It is commonly transmitted through sexual contact. HPV does not typically involve the skull and spine (A), kidneys (C), or heart (D). Choosing B is based on understanding the typical sites of HPV infection and its mode of transmission.

Correct Answer: B

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.

Correct Answer: D

Rationale: The correct answer is D: Quarrelsome. The word "bellicose" means demonstrating aggression and willingness to fight.

The other choices are incorrect because: A: Beautiful - This does not align with the negative behavior exhibited by the children. B: Selfless - This word has a positive connotation, which does not fit the context of the sentence. C: Tolerant - This word means showing acceptance or openness, which contrasts with the aggressive behavior implied by "bellicose."
