The chain of command is

Correct Answer: C

Rationale: The correct answer is C because the chain of command refers to the hierarchical structure within an organization that outlines the line of authority and communication. This ensures that decisions and information flow efficiently from top management to frontline employees. Option A is incorrect as it describes legal responsibility. Option B is incorrect as it refers to a shift supervisor, not the entire chain of command. Option D is incorrect as it describes a specific department, not the overall structure of authority. Ultimately, understanding the chain of command is crucial for effective communication and decision-making within an organization.

Correct Answer: D

Rationale: The correct answer is D: Taste. Taste is not typically used in making observations because observations rely on external stimuli that can be seen, touched, or smelled. Taste involves consuming food or drink, which is not a common method of observation. Sight (A), touch (B), and smell (C) are commonly used senses in making observations. Each of these senses provides valuable information about the external world, making them essential for observation. Taste, on the other hand, is more subjective and personal, making it less reliable and applicable for objective observations.

Correct Answer: A

Rationale: The correct answer is A: Hear. Even though a person in a coma is unconscious and unresponsive, their auditory pathways are still active, allowing them to process sound stimuli. This is supported by research showing brain activity in response to familiar voices and sounds in comatose patients. Choices B, C, and D are incorrect because speaking, seeing, and walking require conscious awareness and motor functions, which are typically impaired or absent in individuals in a coma. Therefore, the ability to hear is the most likely sensory function to remain intact in a comatose state.

Correct Answer: D

Rationale: The correct answer is D: Surgical asepsis. Surgical asepsis refers to the practice of creating and maintaining a sterile environment to eliminate all microorganisms. This is crucial in surgical procedures to prevent infections. Infection prevention (choice A) focuses on strategies to reduce the risk of infections but does not necessarily involve complete elimination of microorganisms. Disinfection (choice B) involves killing or inactivating most disease-causing microorganisms, but it does not guarantee complete elimination. Transmission (choice C) refers to the spread of microorganisms from one person to another, which is different from making an area or object completely free of microorganisms.

Correct Answer: B

Rationale: The correct answer is B: The vaccine for HBV helps prevent the disease. This is true because the hepatitis B vaccine is highly effective in preventing HBV infection. It works by stimulating the immune system to produce antibodies that provide protection against the virus. Healthcare workers are recommended to get vaccinated due to the occupational risk of exposure. Choices A, C, and D are incorrect: A: HBV is a serious threat to healthcare workers due to the potential for occupational exposure to infected blood or bodily fluids. C: HBV is primarily spread through exposure to infected blood or bodily fluids, not through drinking contaminated water. D: HBV can cause severe liver damage, liver cancer, and even death if left untreated.
