A nurse sees smoke coming from the central supply room. Which of the following actions should the nurse take first?

When caring for a client who has an irregular heart rate, the nurse should auscultate the client’s apical pulse to accurately assess their heart rate1. An electrocardiogram (ECG or EKG) may also be used to measure the timing and duration of each electrical phase in the heartbeat

Answer: B. A client who is unconscious.

A. A client who has a spinal cord injury.
While a spinal cord injury is serious and requires close monitoring, this condition does not immediately indicate that the client is unstable or at risk for life-threatening complications compared to an unconscious client. However, if there were signs of respiratory compromise or neurogenic shock, this client could be prioritized higher.

B. A client who is unconscious.
An unconscious client should be seen first because their condition may indicate a critical issue such as impaired airway, breathing, or circulation (ABC). Immediate assessment is needed to ensure the airway is clear, breathing is adequate, and circulation is stable, as these are life-threatening concerns.

C. A client who has peripheral vascular disease.
Clients with peripheral vascular disease (PVD) typically have chronic issues related to circulation in the limbs, which can cause pain and discomfort but are not usually immediately life-threatening. While important, this client is not the top priority compared to an unconscious client.

D. A client who has a new ankle sprain.
A new ankle sprain is painful and requires treatment, but it is not life-threatening. The nurse should address this client after ensuring the more urgent needs of other clients are met, such as the unconscious client who may require immediate interventions to preserve life.
