Which practice was added to Standard Precautions mainly to protect patients rather than personnel?

1. Three areas of practice were added to Standard Precautions: Respiratory Hygiene and Cough Etiquette, safe injection practices, and masks for certain lumbar puncture procedures. 2. Most other elements grew out of Universal Precautions, which were built to protect healthcare personnel. 3. The added elements focus on protection of patients instead. 4. Gloves, gowns and hand hygiene predate these additions and are not the new material. _Source: CDC Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Healthcare Settings (2007), Part III, section III.A.1.
