Final answer:
The most appropriate transmission precautions for a patient with suspected Anthrax exposure pre-decontamination would be Airborne Precautions (c).
Step-by-step explanation:
The most appropriate transmission precautions for a patient in the ED with suspected Anthrax exposure pre-decontamination would be Airborne Precautions (c).
Anthrax is primarily transmitted through respiratory droplets, making it a potential airborne pathogen. Airborne precautions would involve using personal protective equipment such as N95 respirators, and the patient would be placed in a negative pressure room to minimize the risk of transmission to healthcare workers and other patients.
Standard precautions (a) would not be sufficient for Anthrax as it requires more specialized measures to prevent transmission. Contact precautions (b) and droplet precautions (d) are not the most appropriate for Anthrax, as it is primarily transmitted through inhalation of spores.
