The study, conducted in 1971, assessed characteristics of licensed practical nurses (LPN's) who worked in occupational health nursing. The survey instrument, a questionnaire, was returned by 591 LPN's in occupational health and provided data related to: personal characteristics, work and setting, administrative and professional functioning, educational characteristics, economics, and verbatim comments. The instrument, an RN-LPN profile, and a review of the data are included in the report. The results of the survey are reported, answering four basic questions that motivated the study: (1) How can LPN's supplement registered nurses (RN's) in industry? Rather than supplement the RN in industry, 75 percent of LPN's work as the only nurse. (2) What additional training in occupational health is needed by the LPN's? Less than 30 percent of LPN's surveyed had additional continuing education in the occupational health area. (3) Can the LPN's function effectively in the delivery of health care services to workers? The LPN frequently performs RN functions in the occupational setting, without sufficient training or supervision. (4) What supervision is needed by the LPN? The data indicates a legal and professional dilemma; in 50 percent of the case studies, the LPN had no supervision. Tabulated data is appended. (MW)
