CHFM Maintenance and Operations 5 — Questions and Answers
Question 1: A hospital's isolation room is measured to have a positive pressure differential instead of the required negative pressure. What is the MOST immediate concern?
- Increased energy consumption from the HVAC system
- Potential spread of airborne pathogens from the room to the corridor (Correct answer)
- Non-compliance with comfort standards for staff
- Increased noise levels from HVAC equipment
Correct answer: Potential spread of airborne pathogens from the room to the corridor
A positive pressure in an isolation room allows airborne pathogens to escape into the corridor, creating an immediate infection control risk for patients, staff, and visitors.
Question 2: What is the primary regulatory driver for maintaining documentation of elevator inspections and certifications in a healthcare facility?
- NFPA 99 medical gas requirements
- State elevator safety laws and ASME A17.1 standards (Correct answer)
- Joint Commission Environment of Care standards EC.02.05.07
- OSHA general industry standards
Correct answer: State elevator safety laws and ASME A17.1 standards
Elevator inspections and certificates of operation are governed by state laws typically based on ASME A17.1, the Safety Code for Elevators and Escalators.
Question 3: During a power outage, which branch of the Essential Electrical System (EES) must restore power to nurse call systems?
- Life Safety Branch
- Critical Branch (Correct answer)
- Equipment Branch
- Normal Branch
Correct answer: Critical Branch
The Critical Branch of the EES, as defined by NFPA 99, includes nurse call systems and must restore power within 10 seconds.
Question 4: A facilities team is using vibration analysis on a hospital air handler. A spike at a frequency equal to the number of fan blades multiplied by RPM indicates:
- Shaft imbalance
- Bearing wear
- Blade pass frequency — possible blade damage or airflow restriction (Correct answer)
- Electrical interference in the motor
Correct answer: Blade pass frequency — possible blade damage or airflow restriction
A vibration spike at blade pass frequency (number of blades × RPM) indicates aerodynamic issues such as blade damage, fouling, or obstructed airflow.
Question 5: Which organization publishes the Facility Guidelines Institute (FGI) Guidelines used for healthcare construction and renovation projects?
- The Joint Commission
- American Institute of Architects
- Facility Guidelines Institute (Correct answer)
- ASHRAE
Correct answer: Facility Guidelines Institute
The Facility Guidelines Institute publishes the Guidelines for Design and Construction of Hospitals and Outpatient Facilities, widely adopted by states for healthcare construction regulation.
Question 6: In a healthcare facility's medical gas system, a master alarm panel must be monitored:
- Only during business hours by the facilities department
- 24 hours a day, 7 days a week at a continuously staffed location (Correct answer)
- Remotely by the gas supplier via telemetry
- Weekly during scheduled rounds by the safety officer
Correct answer: 24 hours a day, 7 days a week at a continuously staffed location
NFPA 99 requires medical gas master alarm panels to be monitored continuously at a location staffed 24/7, such as a nursing station or security desk.
Question 7: A Planned Preventive Maintenance (PPM) completion rate below what threshold typically triggers a regulatory compliance concern for Joint Commission-accredited facilities?
- 100%
- 95% (Correct answer)
- 90%
- 85%
Correct answer: 95%
The Joint Commission expects facilities to achieve at least a 95% PM completion rate; rates below this threshold are likely to generate findings during surveys.
A hospital's isolation room is measured to have a positive pressure differential instead of the required negative pressure.
