9. You should always observe and practice standard (universal) precautions. True False

**Answer:** True **Explanation:** Standard (universal) precautions are a set of guidelines designed to protect healthcare workers and patients from the transmission of infectious diseases. These precautions assume that all blood, body fluids, secretions, excretions, and non-intact skin may contain transmissible pathogens, regardless of the patient's diagnosis or presumed infection status. By consistently applying these precautions, healthcare professionals can minimize the risk of infection and ensure a safe environment for both themselves and those they care for. **Key Components of Universal Precautions:** 1. **Hand Hygiene:** Regular and thorough washing of hands before and after patient contact. 2. **Personal Protective Equipment (PPE):** Use of gloves, masks, gowns, and eye protection when exposure to potentially infectious materials is possible. 3. **Safe Injection Practices:** Using sterile equipment for each injection to prevent cross-contamination. 4. **Proper Handling and Disposal of Sharps:** Safe management of needles and other sharp instruments to prevent accidental injuries. 5. **Respiratory Hygiene/Cough Etiquette:** Practices to contain respiratory secretions, such as covering the mouth and nose with a tissue or elbow when coughing or sneezing. Consistently observing these precautions is essential in all healthcare settings to prevent the spread of infections and ensure the safety of both healthcare providers and patients.
