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

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.14.3 ACH
• B.15.6 ACH
• C.12.5 ACH
• D.13.6 ACH
