The nurse on the long-term care unit is concerned about the
incidence of pressure ulcers in the facility. He has noted what
feels like an increase in pressure ulcers for clients who have
cognitive impairment. As he considers how to address this problem,
it becomes clear that he must identify not only clients with
cognitive impairment but also individuals with a combination of
cognitive impairment and pressure ulcers. He also notes that he
would like to identify the clients with cognitive impairment who
are most at risk before the pressure ulcers occur.

current residents presently with cognitive impairment and pressure
ulcers. This is known as what type of sampling?
2. Describe the bias concern with this type of sampling
(a retrospective chart audit of all current residents with
cognitive impairment and pressure ulcers).

sampling as opposed to nonprobability sampling?
