Which procedure is unnecessary for a client with pertussis?

Maintaining negative air pressure is unnecessary for a client with pertussis because this disease is primarily spread through large respiratory droplets when an infected person coughs or sneezes. While airborne precautions with negative pressure rooms are critical for illnesses that can remain suspended in the air and be transmitted over longer distances, pertussis does not require such measures. The primary focus for pertussis is to protect against droplet spread, which can be managed through proper patient management and isolation in a regular room.

Other precautions, such as ensuring the client has disposable utensils, wearing a surgical mask during client transport, and keeping the patient's door closed, are relevant in reducing the risk of transmission. These measures help minimize the exposure of healthcare workers and other clients to respiratory droplets, which is essential in controlling the spread of pertussis. Thus, negative air pressure is not an appropriate requirement for managing a patient with this condition.
