Which of the following statements is correct about universal precautions?

Universal precautions are an essential set of guidelines developed to prevent the transmission of infectious diseases in healthcare and investigative settings. The concept behind universal precautions is to treat all blood and bodily fluids as potentially infectious, regardless of the apparent health status of the individuals involved.

Following these precautions in every death investigation is critical because each case might involve unknown pathogens, and the risk of exposure to infectious materials is present at all times. This clear guideline ensures that investigators, medical examiners, and law enforcement personnel safeguard their own health while conducting their work. It emphasizes the importance of applying these protocols consistently, rather than selectively, to prevent the risk of occupational exposure to bloodborne pathogens and other infectious materials.

The other statements suggest either a limitation or an optional nature of universal precautions, which undermines their foundational principle. They should be seen as mandatory practices within every investigative context, rather than something that can be adjusted based on visibility of injuries or an individual's known health status.
