Correct Answer: B

Rationale: To critique something means to evaluate and judge it, often pointing out its faults or shortcomings. Condemning something implies expressing strong disapproval or criticism of it, which aligns closely with the concept of critiquing. 'Appraise' means to assess the value or quality of something, which is not necessarily negative. 'Extol' means to praise highly, which is the opposite of critiquing. 'Berate' means to scold or criticize someone angrily, which is not the same as objectively evaluating something as in critiquing. Therefore, 'condemn it' is the most suitable choice among the given options.

Correct Answer: D

Rationale: When a symptom is exacerbated, it means that it is made worse or intensified beyond its usual level of severity. This can lead to increased discomfort, pain, or other negative effects associated with that particular symptom. Choice A is incorrect because exacerbation does not imply that the symptom is not dangerous. Choice B is incorrect as exacerbation does not necessarily mean disfiguring. Choice C is incorrect as exacerbation does not always specifically refer to pain, but to any worsening of a symptom.

Correct Answer: A

Rationale: Corrected Question: In this context, the word 'rationale' refers to the underlying reasoning or justification for the treatment being explained step-by-step by the doctor. It pertains to the logical basis or thought process behind the chosen course of action. 'Prescription' (Choice B), 'Procedure' (Choice C), and 'Necessity' (Choice D) do not accurately capture the meaning of 'rationale' in the sentence provided.

Correct Answer: D

Rationale: Urea is the correct answer. It is the crystalline compound formed in the liver from the breakdown of proteins, a byproduct of protein metabolism. Urea is excreted by the kidneys in the form of urine, aiding in the elimination of nitrogenous waste from the body. Uracil (Choice A) is a nitrogenous base found in RNA, not a product of protein metabolism. Urine (Choice B) is the liquid waste excreted by the kidneys but not the crystalline compound resulting from protein metabolism. Ureter (Choice C) is a duct that carries urine from the kidneys to the bladder, not the compound produced from protein metabolism.

Correct Answer: A

Rationale: The correct answer is A: "convulsion." A paroxysm is defined as a sudden spasm or convulsion. The word "convulsion" specifically refers to a violent and involuntary contraction or spasm of muscles, which aligns perfectly with the description of a paroxysm. On the other hand, choices B, C, and D are incorrect. "Symptom" (B) refers to a manifestation of a condition rather than a physical spasm. "Efficacy" (C) relates to effectiveness or success, not a sudden spasm. "Embolism" (D) refers to the obstruction of a blood vessel, which is unrelated to the concept of a sudden spasm. Therefore, convulsion is the most suitable synonym for a paroxysm in this context.
