Which groups are vulnerable and often require help in achieving a safe
environment?
Infants, children, older adults, the ill, the physically and mentally disabled, the illiterate,
and the poor
What is all included in order to have a safe environment?
Meeting basic needs, reducing physical hazards and the transmission of pathogens,
and controlling pollution
What are some things that influence a patient's safety?
Physiological needs, including the need for sufficient oxygen, nutrition, and optimum
temperature
True/False: Oxygen is flammable?
False
Fire just needs oxygen to start and to keep burning
Smoking is the leading cause of what?
Burns, reported fires, deaths, and injuries involving home medical oxygen.
