In preventing the spread of a communicable disease from an infected client, what is the PN's next practical action after basic hand hygiene and respiratory etiquette?

• A. Place the client in isolation and revert to routine practices.
• B. Administer broad-spectrum antibiotics.
• C. Wait for lab confirmation before isolating.
• D. Assist with rapidly identifying the disease and immediately isolating.

Answer: (D)

The next practical action is to rapidly identify the likely infectious disease and immediately implement isolation to prevent transmission. Once basic hand hygiene and respiratory etiquette are in place, you don’t wait for lab results to start containment. Recognize signs and symptoms that suggest a contagious illness and apply the appropriate isolation precautions right away (for example, using droplet or contact precautions as indicated, with proper PPE). This early step is essential to protect other patients and staff while awaiting confirmation. Antibiotics aren’t used to prevent spread and aren’t given until a diagnosis supports their use. Reverting to routine practices or delaying isolation increases the risk of spreading the infection.
