What is the primary purpose of standard precautions in healthcare?

• A. To prevent transmission by treating all blood and body fluids as potentially infectious and using PPE, hand hygiene, and safe handling.
• B. To isolate patients with confirmed infections only.
• C. To replace the need for hand hygiene in healthcare settings.
• D. To only use PPE during surgical procedures.

Answer: (A)

The main idea behind standard precautions is to prevent the spread of infection by treating all blood and body fluids as potentially infectious and consistently using protective measures. In real-world care, you don’t rely on whether a patient is known to be infected; instead, you apply the same safety habits to every encounter. That means performing thorough hand hygiene before and after contact, wearing appropriate PPE (gloves, gown, mask, eye protection) when exposure or splashes could occur, and handling needles, sharps, and contaminated surfaces and materials safely. It also includes safe injection practices and proper cleaning and disinfection of equipment and the environment, extending to mucous membranes and non-intact skin.

This approach minimizes risk from both obvious and unrecognized infections, protecting both healthcare workers and patients. Relying only on isolating confirmed infections or using PPE only during surgical procedures misses risks present in routine care, where infections can still be transmitted through ordinary patient interactions and common procedures. Standard precautions provide a baseline layer of protection that is applied in every interaction, forming the foundation of safer healthcare.
