A nurse is assisting with the admission of a client who has leukemia. Which of the following transmission precautions should the nurse implement?

Choice A reason: Wrapping the dressing in a clear plastic bag and discarding it in the bedside trash receptacle is not an appropriate method for disposing of soiled dressings. This approach does not comply with standard infection control protocols, as it could potentially expose healthcare workers and others to biohazardous materials.

Choice B reason: Simply discarding the dressing in the bedside trash receptacle is also inappropriate and unsafe. This method does not contain the biohazardous material properly and could lead to contamination and spread of infectious agents.

Choice C reason: Placing the dressing in a biohazardous waste container is the correct method for disposing of dressings saturated with blood and purulent drainage. According to infection control guidelines, materials that are soaked with potentially infectious agents should be disposed of in designated biohazardous waste containers. These containers are typically red or yellow and are labeled to indicate that they contain materials that require special handling.

Choice D reason: Double bagging the dressing, labeling it "biohazard," and sending it for decontamination is an unnecessary step for routine disposal of soiled dressings. While double bagging may be used in situations where there is a significant spill or leak risk, it is not typically required for standard disposal of wound dressings.

Choice A reason: A systemic infection would affect the entire body or multiple systems, not just the urinary tract. While a urinary tract infection can become systemic if it leads to sepsis, the scenario provided does not specify such progression.

Choice B reason: A health care-associated infection (HAI) is an infection that a patient acquires while receiving treatment for another condition within a healthcare setting. Since the infection occurred after the insertion of a urinary catheter in a hospital, it is considered an HAI.

Choice C reason: An endogenous infection originates from the host's own microbial flora. The scenario does not provide enough information to determine if the infection was caused by the client's own flora or by external sources.

Choice D reason: An exogenous infection comes from outside the body. While the urinary tract infection could be exogenous, the scenario suggests it is more likely to be health care-associated due to the timing and context of the catheter insertion.
