What is the purpose of isolation precautions?

• A. To increase patient isolation for privacy.
• B. To reduce staff workload by limiting contact.
• C. To ensure patient comfort by reducing noise.
• D. To prevent the spread of infections from patients known or suspected to be infected.

Answer: (D)

Isolation precautions exist to prevent the spread of infections from patients who are known or suspected to be infected. They focus on interrupting transmission by using standard precautions plus transmission-based measures tailored to how an infection spreads—through contact, droplets, or airborne routes. The primary aim is to protect other patients, healthcare workers, and visitors by guiding actions like placing the patient in an appropriate room, donning the correct PPE (gloves, gown, mask or respirator, eye protection as needed), practicing meticulous hand hygiene, and ensuring proper environmental cleaning. Privacy or comfort may be affected by isolation, but the main purpose is to stop the infection from spreading.
