RATIONALE: Studies of those who commit suicide reveal the following high-risk groups: adolescents; men over age 45; persons who have made previous suicide attempts; divorced, widowed, and separated persons; professionals, such as physicians, dentists, and attorneys; students; unemployed persons; persons who are depressed, delusional, or hallucinating; alcohol or substance abusers; and persons who live in urban areas. Although more women attempt suicide than men, they typically choose less lethal means and therefore are less likely to succeed in their attempts.NURSING PROCESS STEP: AssessmentCLIENT NEEDS CATEGORY: Safe, effective care environmentCLIENT NEEDS SUBCATEGORY: Safety and infection controlCOGNITIVE LEVEL: Knowledge
