Rationale: The correct answer is C because the chain of command represents the hierarchical structure within an organization, outlining who reports to whom. It ensures clear communication, accountability, and efficient decision-making. Option A is incorrect as it refers to legal liability. Option B is incorrect as it only refers to the department head, not the entire structure. Option D is incorrect as it focuses on reporting a problem rather than the overall structure of authority.

Rationale: The correct answer is D: Taste. Taste is not typically used in making observations because it requires the consumption of a substance to gather information, which may not be practical or safe in all situations.

Rationale: The correct answer is A: Hear. Even though a person in a coma may appear unconscious, their auditory system is often still functional. Studies have shown that comatose patients can respond to auditory stimuli, indicating that they can indeed hear. This ability to hear can be crucial for communication and potentially aiding in their recovery. Choices B, C, and D are incorrect as speaking, seeing, and walking require conscious control and coordination of different body systems, which are typically impaired in a comatose state.

B: Disinfection is the process of reducing the number of microorganisms but may not eliminate all. C: Transmission refers to the spread of microorganisms from person to person and is not specific to making an area or object microorganism-free.

Choice A is incorrect as HBV is indeed a serious threat to healthcare workers. Choice C is incorrect as HBV is primarily spread through blood-to-blood contact, not by drinking contaminated water. Choice D is incorrect as HBV can lead to severe complications and even death if left untreated.
