A nurse is checking the apical pulse of a client who is taking several cardiovascular medications. Which of the following actions should the nurse take?

Choice A reason: Placing a client with active pulmonary TB in a room with positive airflow is not recommended, as positive airflow would push potentially contaminated air into general circulation, risking the spread of TB. Instead, a room with negative airflow is appropriate to contain and remove contaminated air.

Choice B reason: Determining whether the client lives alone or with others is important for public health and contact tracing purposes. If the client lives with others, those individuals may need to be tested and monitored for TB as well.

Choice C reason: Using an alcohol-based hand cleaner is a standard practice unless hands are visibly soiled. If hands are visibly soiled, handwashing with soap and water is necessary.

Choice D reason: Reminding the client to cover their mouth with a tissue when coughing is a key measure to prevent the spread of TB, which is transmitted through airborne particles from coughs or sneezes.

Choice E reason: Antifungal medications are not used to treat TB, which is caused by a bacterium, not a fungus. The client should be instructed about taking anti-tuberculosis medications, not antifungals.

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.
