4B051 CDC Vol 5 UREs Questions and Answers Already Passed What is the primary purpose of ventilation in a healthcare facility? To ensure the circulation of clean air and remove contaminants. Why is proper ventilation important in surgical suites? It minimizes airborne pathogens and maintains a sterile environment. What role does ventilation play in infection control? It helps reduce the spread of airborne infectious agents. How does air pressure affect ventilation in isolation rooms? Negative air pressure prevents contaminants from spreading to other areas. What is the purpose of HEPA filters in ventilation systems? HEPA filters remove particles, allergens, and microorganisms from the air. 2 Why must exhaust air be treated in certain hospital areas? To ensure contaminants are removed before the air is released outside. How often should ventilation systems be inspected in medical facilities? They should be inspected regularly, typically quarterly or semi-annually, to ensure proper function. What is the purpose of directional airflow in healthcare settings? To control the movement of air between clean and contaminated zones. Why are ventilation rates higher in operating rooms compared to offices? To maintain sterility and remove contaminants quickly. What is the function of a laminar airflow system? It directs a continuous, unidirectional flow of air to minimize contamination. How is airflow measured in ventilation systems? Airflow is measured using an anemometer or similar device to ensure proper circulation. 3 What is a key requirement for air exchange rates in patient rooms? A minimum number of air changes per hour to maintain air quality standards. Why is humidity control essential in ventilated healthcare spaces? To prevent mold growth and maintain patient comfort. What is the role of return air vents in a ventilation system? They capture used air and direct it back to the system for filtration or exhaust. How does proper ventilation impact staff safety in laboratories? It reduces exposure to hazardous fumes and airborne contaminants. Why are isolation rooms equipped with special ventilation systems? To contain and control infectious diseases within a confined area. What is the purpose of a fume hood in a ventilation system? It protects users from harmful gases by venting them safely outside. 4 How can ventilation systems contribute to energy efficiency? By using heat recovery ventilators to reclaim energy from exhaust air. What happens if ventilation systems are improperly balanced? It can lead to uneven air distribution and compromised air quality. Why is air pressure monitoring important in critical care units? To ensure the proper flow of air and maintain a safe environment for patients. How does outdoor air intake benefit
