A nurse is preparing to administer warfarin to a client who has chronic atrial fibrillation. Which of the following laboratory values should the nurse monitor prior to administering the medication?

Choice A Reason:

Setting the degree of flexion and extension as tolerated by the client is generally appropriate in a CPM device, but this should be done within the prescribed range recommended by the healthcare provider. Simply allowing the client to adjust the degree of flexion and extension without guidance might lead to overextension or inadequate movement, potentially causing discomfort or hindering recovery.

Choice B Reason:

Padding the CPM device with a thick pillow isn't the recommended approach. CPM devices typically come with appropriate padding to ensure comfort and proper positioning. Using a thick pillow might alter the device's mechanics or cause uneven support, affecting the intended movement of the knee.

Choice C Reason:

Placing the client in high-Fowler's position (sitting upright at a 90-degree angle) isn't a standard or necessary position for using a CPM device after a knee arthroplasty. The client can typically use the CPM device while lying in a comfortable and relaxed position, following the healthcare provider's instructions regarding positioning during CPM therapy.

Choice D Reason:

Aligning the client's joints with the joints on the frame is essential for the correct function of the CPM device. This alignment helps in providing the intended range of motion without causing unnecessary stress or strain on the knee joint.

Choice A Reason:
Using a fire extinguisher at the source of the smoke is not appropriate. While using a fire extinguisher could potentially help contain a small fire, it's crucial to prioritize rescuing those in immediate danger and alerting others about the fire first by activating the fire alarm. This action ensures that help is on the way and that everyone is aware of the emergency.
Choice B Reason:
Closing the doors to the room and to the bathroom is not appropriate. Closing doors can help contain smoke and fire to some extent, but again, the priority in an emergency situation like this is to rescue those in immediate danger then activate the fire alarm to ensure a swift response and alert others.
Choice C Reason:
Activate the fire alarm system is appropriate. Activating the fire alarm alerts others in the facility and initiates the emergency response protocol, helping to ensure that help is on the way while potentially preventing the spread of fire. However, this step should be taken after assisting the client to safety as they are in immediate danger.
Choice D Reason:
Assisting the client who is in immediate danger to a nearby common area should be the furst step that the nurse takes before alerting other people of the fire. (RACE protocol)
