HESI A2 Vocabulary 2024

Correct Answer: A

Rationale: The correct answer is A: drug. PDR stands for Physician's Desk Reference, which is a comprehensive guide to prescription drugs. It provides detailed information about drug interactions, side effects, and dosages. Therefore, choice A is correct. The other choices (B, C, and D) are incorrect because PDR specifically refers to drugs and not procedures, books, or muscle groups.

Correct Answer: B

Rationale: The correct answer is B: Cut. A laceration refers to a deep cut or tear in the skin or flesh. In this context, the sentence mentions a painful injury, which aligns with the definition of laceration as a type of cut. Choices A, C, and D are incorrect because gait refers to a person's manner of walking, headache is a type of pain in the head, and welt is a raised mark on the skin, none of which match the meaning of laceration in the given sentence.

Correct Answer: B

Rationale: The correct answer is B: Improve. In the given sentence, 'ameliorate' is used in the context of making something better or reducing its negative effects, which aligns with the meaning of 'improve.' It means to alleviate or enhance a situation. Choices A, C, and D are incorrect because 'ameliorate' does not mean to cause, reveal, or restore in this context. The word 'ameliorate' specifically implies a positive change or enhancement, making 'improve' the most suitable choice.

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: B

Rationale: The correct answer is B: bleeding. A hemostat is a surgical tool used to control bleeding by clamping blood vessels. It does not address pain (A), fever (C), or coughing (D). Pain is managed with analgesics, fever with antipyretics, and coughing with cough suppressants. Therefore, the correct choice is B as a hemostat is specifically designed for controlling bleeding during medical procedures.
