For each potential provider's prescription, click to specify if the potential prescription is anticipated or contraindicated for the client:

A) Open the fireplace dampers in the day room:
Opening the fireplace dampers in the event of an external chemical disaster would not be appropriate. In fact, this could allow toxic air or chemicals to enter the facility. It is important to seal off ventilation points that might allow the chemicals to enter, such as windows, doors, and any other openings, rather than opening the dampers.

B) Move clients to a room above ground with few windows:
In the event of an external chemical disaster, moving clients to a room above ground with few windows is a key safety measure. Rooms that are above ground level tend to be safer in such situations because chemicals may settle at ground level, increasing exposure risks to those below ground. A room with few windows is also important because it minimizes potential entry points for toxic substances from outside. The focus is on containing the air supply and limiting exposure to harmful agents.

C) Turn on fans in the facility to circulate air:
Turning on fans in the facility during a chemical disaster could worsen the situation by spreading toxic air or chemicals throughout the building. Fans are generally used to circulate air, but in this context, they would not be helpful and could potentially increase exposure to harmful substances. Instead, the focus should be on reducing airflow from the outside and sealing off the building.

D) Cover the electrical outlets with wet towels:
Covering electrical outlets with wet towels is not an effective response to an external chemical disaster. While wet towels can be useful in some scenarios for filtering or protecting from certain substances, in a chemical disaster, the priority is to ensure proper ventilation control and to protect from airborne chemicals by sealing the room. Electrical outlets should be covered for safety only when there is a risk of electrical hazards, but not necessarily in the case of a chemical disaster unless there is specific concern about sparks or fire.

A) "Ensure that the negative air pressure is active for the client’s room.": Negative air pressure is used for airborne precautions, such as in the case of tuberculosis or other airborne infections. MRSA is primarily spread through direct contact, not airborne transmission, so negative air pressure is not necessary in this situation.

B) "Place the client in a room with a high-efficiency particulate air (HEPA) filter.": A HEPA filter is used for airborne precautions to filter out airborne particles like those found in diseases such as tuberculosis or measles. Since MRSA is transmitted through direct contact and not airborne particles, placing the client in a room with a HEPA filter is not necessary.

C) "Have the client wear a mask when they are out of their room.": MRSA is typically spread by direct contact with infected wounds, bodily fluids, or contaminated surfaces. It is not transmitted via respiratory droplets, so there is no need for the client to wear a mask when they leave their room. The focus should be on contact precautions rather than respiratory precautions.

D) "Don gloves prior to assisting the client with brushing their teeth.": MRSA is a contact-borne infection, so it is essential to use proper personal protective equipment, such as gloves, when coming into direct contact with the client or any of their bodily fluids or contaminated items (such as toothbrushes). Donning gloves prior to assisting with brushing their teeth ensures that the nurse avoids direct contact with potential sources of infection. This is an important measure in preventing the spread of MRSA.
