Correct Answer: C

Rationale: The correct answer is 'C: Preventive measure.' A precaution is a preventive action taken to avoid harm or danger. 'Rule' (A) and 'Habit' (D) do not capture the essence of being cautious to prevent something negative. 'Routine procedure' (B) is related to a regular way of doing things, but it does not specifically imply taking action to prevent harm.

Correct Answer: B

Rationale: The word 'ritualistic' is an adjective that describes actions or behaviors performed in a habitual or symbolic manner, often resembling a ritual. In this context, it best describes the patient's behavior of repeatedly and meticulously arranging food on the plate. 'Formal' (Choice A) does not capture the habitual or symbolic aspect of the behavior. 'Formalizing' (Choice C) is a verb form and does not describe the behavior itself. 'Ritual' (Choice D) is a noun and does not fit as well here since the question is asking for an adjective to describe the behavior.

Correct Answer: D

Rationale: In the United States, drivers drive on the 'right' side of the road. This is the standard practice in the country. Choice A 'Rite' is incorrect as it is a misspelling of 'Right.' Choice B 'Left' is incorrect as driving on the left side is common in countries like the UK, not the US. Choice C 'Off-side' is incorrect as it is not a standard term used to describe the side of the road where people drive in the US.

Correct Answer: D

Rationale: The correct answer is D: 'Soon to occur.' The word 'impending' is used to describe something that is about to happen or is soon to occur. In the context of the sentence provided, 'impending' operation indicates that the operation is about to take place. Choices A, B, and C are incorrect because 'impending' does not mean 'very serious,' 'required,' or 'elective.' Instead, it specifically refers to the timing of the operation as being imminent.

Correct Answer: B

Rationale: The term 'residual' refers to what is left after the main part has been taken or used. In this context, 'residual urine' specifically means the urine that remains in the bladder after urination. Choices A, C, and D do not accurately capture the meaning of 'residual' in this sentence. 'Measurement' (A) is too general, 'Total volume' (C) does not specifically pertain to what remains, and 'Color and clarity' (D) is unrelated to the concept of what is left.
