A nurse is monitoring a client who has diabetes mellitus and a glucose level of 384 mg/dl. (74 to 106 mg/dL). Which of the following findings should the nurse identify as an indication of metabolic acidosis?

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)

Choice A Reason:

Place on airborne precautions. This is incorrect. Tinea corporis isn't transmitted through the air. Airborne precautions are specific infection control measures for diseases transmitted through airborne particles, like tuberculosis or measles, which are caused by specific bacteria or viruses.

Choice B Reason:

Avoid direct contact is correct. Direct contact is a crucial precaution to prevent the spread of tinea corporis. It's a contagious infection, often transmitted through skin-to-skin contact or by sharing contaminated items such as clothing, towels, or bedding. Encouraging precautions like not sharing personal items and avoiding direct skin contact helps prevent the spread of the infection to others.

Choice C Reason:

Isolate for 24 hr. after lesions appear is incorrect. While it's essential to take precautions to prevent spread, isolating for only 24 hours after lesions appear might not be sufficient. The infection can remain contagious until it's effectively treated and lesions have resolved. More extended isolation or precautions might be necessary until the infection is no longer transmissible.

Choice D Reason:

Administer a broad-spectrum antibiotic is incorrect. Tinea corporis is a fungal infection, not a bacterial one, so antibiotics would not be effective against it. Antifungal medications, such as topical or oral antifungals, are the primary treatment for tinea corporis. Using an antibiotic would not treat the fungal infection and might lead to inappropriate medication use.
