Complete CHFM AHA Materials

Comprehensive and Detailed Explanation From Exact Extract:

Symptoms such as nausea, dizziness, headaches, and drowsiness are commonly associated with poor indoor air quality (IAQ). The most likely cause in this case is insufficient outside air ventilation, which allows buildup of carbon dioxide and other indoor contaminants.

Correct Answer (C. insufficient outside air): According to ASHRAE Standard 62.1 (Ventilation for Acceptable Indoor Air Quality) and referenced in NFPA 99 Health Care Facilities Code, inadequate outside air results in occupant discomfort and health complaints known as “sick building syndrome.”

Incorrect Options:

A. mercury spill: Causes more acute, localized toxic exposure symptoms; less likely across an entire wing unless a large spill occurred (and it would be unusual in general occupancy areas).

B. humidity levels: Low or high humidity can cause discomfort, but not typically dizziness or drowsiness.

D. medical gas leak: Could cause similar symptoms depending on the gas, but would typically trigger alarms and affect specific zones tied to gas lines, not general wing-wide complaints.

Relevance to CHFM:

This question relates to the Compliance and Maintenance & Operations domains. CHFM professionals must ensure compliance with ventilation codes (ASHRAE 62.1, NFPA 99, Joint Commission EC standards) and manage HVAC systems to maintain proper indoor air quality, protecting patient and staff health.

NFPA opening-protective tables specify that doors protecting openings in 2-hour fire-resistance-rated fire barriers are required to have a 1-1/2-hour (90-minute) fire protection rating. This distinction between the wall’s fire-resistance rating and the door’s fire-protection rating is standard in NFPA 101 and NFPA 80.

EPA and OSHA define regulated medical waste (RMW) as waste that is saturated or dripping with blood or other potentially infectious materials (OPIM).

B. Blood-saturated gauze (Correct): Meets the definition of RMW.

A. Fluorescent bulbs: Considered hazardous universal waste (mercury), not RMW.

C. Urine-soaked pads: Not classified as RMW unless visibly contaminated with blood.

D. Home-use sharps: Not regulated by EPA as medical waste from households.

Building automation system (BAS) costs are based largely on the number of control points (sensors, outputs, and monitored parameters) that must be integrated. The cost is driven by how many signals must be tracked, rather than just the square footage or vendor.

A: Gross square footage can influence scope, but cost scales with monitored points.

B: Vendor may affect pricing, but primary cost driver is point count.

C: Technology choice matters, but the quantity of control points is more significant.
