A nurse is caring for a client who acquired a Staphylococcus aureus infection from touching a contaminated towel. Through which of the following modes of transmission did the client acquire the infection?

The nurse should choose a finger with good circulation, as indicated by a capillary refill time of less than 2 seconds, to obtain an accurate oxygen saturation reading.

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.
