Final answer:
Tanisha should look for secondary exits such as stairwells or fire escapes, or find a safe room with a window if exits are blocked. She must avoid elevators, keep low to avoid smoke, and alert emergency services.
Step-by-step explanation:
If Tanisha is trying to lead her patients to safety and the primary exit is blocked by fire, she should immediately seek alternative escape routes, such as a secondary stairwell or fire escape. If all typical escape routes are blocked, she should find a safe room to shelter in, preferably with a window to signal for help, and seal any cracks or openings to slow the spread of smoke.
Tanisha should keep calm, reassure her patients, and use any available communication devices to alert emergency services of their location within the building. It is crucial to avoid elevators during a fire, as they may become inoperable or lead to a floor with heavier fire activity.
Everyone should stay low to the ground to avoid inhaling smoke, which is the leading cause of death in a fire. Additionally, if it is safe to do so, they should use fire extinguishers to clear a path or wet cloths to cover their mouths and noses.
