A nurse in an assisted-living facility reinforcing teaching with staff members about preparing for an external chemical disaster. Which of the following instructions should the nurse include?
"Open the fireplace dampers day room."
"Move clients to a room above ground with few windows."
"Turn on fans in the facility to circulate air."
"Cover the electrical outlets with wet towels."
The Correct Answer is B
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.

Correct Answer is D
Explanation
A) You should avoid exercising for the next 6 weeks:
This statement is not accurate. The client is encouraged to gradually increase activity and participate in physical therapy as prescribed to improve mobility and strength following a total hip arthroplasty. While some rest and limited activity may be necessary immediately after surgery, complete avoidance of exercise for six weeks is generally not advised unless there are complications. Physical therapy exercises are often a key component in the recovery process after hip replacement surgery.
B) You should avoid lying on your right side:
This recommendation is incorrect unless specifically contraindicated due to complications. After a right total hip arthroplasty, the client can typically lie on either side once they are comfortable, unless instructed otherwise by the healthcare provider. It is important to follow the surgical instructions regarding positioning, especially avoiding positions that might place stress on the new joint
C) You should avoid putting a pillow between your legs when in bed:
This statement is incorrect. After a total hip arthroplasty, placing a pillow between the legs when lying on either side is recommended to maintain proper alignment of the hip joint and prevent dislocation. The pillow helps keep the legs slightly apart, preventing the hip from rotating inward, which can put the new joint at risk for dislocation.
D) You should avoid crossing your legs formonths:
This is correct. Following a total hip arthroplasty, it is essential to avoid crossing the legs, especially for the first several months. Crossing the legs can lead to hip dislocation or improper alignment of the joint. The nurse should reinforce the importance of avoiding crossing the legs both while sitting and lying down to ensure proper healing and to avoid complications such as dislocation of the new hip joint.
