Final answer:
In managing open soft-tissue injuries, the use of Standard Precautions by EMTs is essential. Antiseptics are the correct choice for microbial control on living tissues. The practical application of cell theory in health care includes the promotion of sterilization and disinfection to prevent infection transmission. The correct option is B.
Step-by-step explanation:
Management of Open Soft-Tissue Injuries
In the management of all open soft-tissue injuries, the use of Standard Precautions by the emergency medical technician (EMT) is required. These precautions involve wearing personal protective equipment like gloves and eye protection to avoid contact with bodily fluids, which helps prevent the transmission of infections.
Microbial Control on Tissues
For microbial control to prevent infection on tissues, the correct substance to use is an antiseptic. Antiseptics are suitable for use directly on living tissues to decrease the risk of infection, whereas disinfectants are typically used on non-living surfaces.
Importance of Sterilization and Disinfection in Health Care
The element of the cell theory that has practical applications in health care, promoting the use of sterilization and disinfection, is the understanding that all living organisms are made of cells and that cells are the basic unit of life.
Sterilization and disinfection are crucial in health care settings to ensure that medical equipments and environments do not contribute to the spread of infections. Control tests, such as those used to ascertain the efficacy of disinfectants, are essential to maintain those standards. Option B. is the correct one.
