Practical and ethical water conservation measures include landscape irrigation reduction (1) and metering cooling tower usage (3) since cooling towers are a major consumer of water.
2. Campaigns: Awareness is useful but not as effective as operational controls.
4. Reducing patient showers: Not appropriate for patient care and safety.

According to NFPA 101 Life Safety Code and CMS/TJC corridor obstruction guidance, only certain items deemed essential for immediate patient care may be left unattended in inpatient care corridors. Crash carts are specifically allowed because they are emergency life-saving equipment. Other items, such as hampers, WOWs, and bins, are considered obstructions and must be removed when not in active use.

CMS Condition of Participation 482.41(c)(2) requires hospitals to ensure that elevator equipment is routinely inspected, tested, and maintained. Appendix A to this regulation clarifies that documentation of these three elements demonstrates compliance.
Correct (C): Maintenance - Inspections and testing alone are insufficient; ongoing maintenance must be documented.
Incorrect:
A). recalls: Not part of CMS 482.41(c)(2).
B). cleaning: While important, cleaning is not listed as a compliance requirement.
D). repairs: Only performed when problems are found; maintenance is the proactive required element.

The RCRA (1976) governs the proper management of hazardous waste from generation to disposal ("cradle to grave"). While healthcare organizations often think of sharps or medical waste, RCRA is broader, addressing hazardous chemicals, solvents, and pharmaceuticals. Medical waste is regulated under other federal and state rules.

Acceptable indoor CO# concentrations in healthcare facilities are generally expected to remain below 1,000 ppm, as recommended by ASHRAE Standard 62.1 (Ventilation for Acceptable Indoor Air Quality). A reading of 1,500 ppm typically signals inadequate ventilation and insufficient outside air being introduced into the space. This is a direct indicator of poor dilution of indoor contaminants.
Correct: Lack of outside air (C) - High CO# concentrations are directly linked to reduced outside air supply.
Incorrect:
A). Within design - Not correct, since 1,500 ppm exceeds design thresholds.
B). Vehicular exhaust - Would raise CO and NOx levels, not primarily CO#.
D). Humidity/dewpoint - Unrelated to CO# measurement.
