1. The isolation room is supplied with 300 cfm (142 L/s) of HEPA filtered air. The return air grille is located in the ceiling and has been balanced to 150 cfm (71 L/s). The room is monitored with a differential pressure sensor, and the sensor is sending an alarm signal to the nurse's station. Which of the following BEST describes the problem?

A) This is a Protective Environment Room with the door to the corridor propped open
B) This is a Protective Environment Room with inadequate toilet room exhaust of 25 cfm (12 L/s)
C) This is an Airborne Infection Isolation Room with the door to the corridor propped open
D) This is an Airborne Infection Isolation Room with inadequate toilet room exhaust of 25 cfm (12 L/s)

2. According to the most current FGI Guidelines, HVAC modifications that affect more than 10% of the system capacity shall?

A) Require a pre-renovation water/air flow rate measurement
B) Require a retrofit to include an economizer/heat recovery
C) Require a DDC control system upgrade
D) Require an upgrade to premium efficiency motors

3. A medical gas storage room with a capacity for over 3,000 cubic ft. (84.95 cubic m) at standard temperature and pressure is required to have a ventilation system with which of the following criteria?

A) The exhaust grille shall be located within 12 in. (31 cm) of the floor
B) The exhaust grille shall be sized for natural ventilation
C) The system shall cycle to meet temperature requirements
D) The system shall be interconnected to the facility AHU system

4. An Airborne Infection Isolation Room is 10 ft. × 12 ft. (3.05 m × 3.66 m) and has an 8 ft. (2.44 m) ceiling. An adjoining anteroom measures 6 ft. × 8 ft. (1.83 m × 2.44 m) with a 7.5 ft. (2.29 m) ceiling height. Airflow measurements reveal: Room supply diffuser: 135 CFM (64 L/s), Exhaust register: 200 CFM (95 L/s), Anteroom supply diffuser: 100 CFM (48 L/s), Anteroom exhaust register: 65 CFM (31 L/s). Which of the following represents the correct patient room air change rate (ACH)?

A) 12.5 ACH
B) 13.6 ACH
C) 14.3 ACH
D) 15.6 ACH

5. HVAC design for cardiac catheterization suites must take into account that the facilities:

A) Require infrequent mechanical upgrades
B) Are required to have treatment rooms with negative pressure
C) Are associated with relatively noninvasive procedures
D) Contain significant electrical equipment loads
