What action should be taken if a disinfectant is infused into a patient's bloodstream due to protocol breach?

In the event that a disinfectant is infused into a patient's bloodstream due to a protocol breach, the appropriate action is to stop the dialyzer and discard the bicarbonate. This is crucial because introducing a disinfectant into the bloodstream can pose serious risks to the patient, including severe complications or adverse reactions.

Discontinuing the dialyzer prevents further circulation of the disinfectant and allows for immediate intervention. Discarding the bicarbonate solution also eliminates any potential for continued infusion of the harmful substance. Following this, it is essential to assess the patient for any signs of reaction and engage in proper emergency protocols, including notifying the healthcare provider and monitoring the patient closely.

Additionally, the other options would not adequately address the immediate risk associated with this situation. For instance, continuing treatment would expose the patient to further danger. Administering medication or starting additional fluids may not address the toxicity of the disinfectant already in the bloodstream and could complicate the situation further. Thus, stopping the dialyzer and discarding the bicarbonate are necessary steps to ensure the safety and health of the patient.
