VULNERABLE POPULATIONS IN
NURSING UNDERSTANDING
HOMELESSNESS, POVERTY,
SUBSTANCE USE, AND VIOLENCE
This comprehensive guide examines the complex challenges faced by
vulnerable populations and the critical role nurses play in addressing
these issues. We explore the intersections of homelessness, poverty,
substance use disorders, violence, and abuse, while highlighting
evidence-based nursing interventions grounded in trauma-informed
care. Throughout this document, you'll discover how social determinants
of health impact these populations and learn practical approaches for
assessment, intervention, referral, and advocacy within public health
nursing practice.
Learning Objectives
,2
Understand Vulnerability and Social
Determinants
Distinguish between types of vulnerability, articulating how social
determinants—including economic stability, neighborhood
environment, and access to healthcare—predispose populations
to poor health outcomes.
Synthesize Knowledge of Violence
Synthesize knowledge of interpersonal, family, and community
violence, including intimate partner violence, child abuse, elder
abuse, and human trafficking, with emphasis on risk assessment
and mandated reporting.
Analyze Substance Use and Violence
Analyze the complex relationship between substance use
disorders and violence, integrating pathophysiology, behavioral
health, and public health perspectives.
Apply the Nursing Process
Demonstrate the use of the nursing process, including screening,
intervention, referral, and advocacy within the context of trauma-
informed and culturally competent care for individuals and
families experiencing vulnerability.
These objectives will guide our exploration of vulnerable populations,
providing a framework for understanding both the challenges these
groups face and the nursing interventions that can make a meaningful
difference in their health outcomes.

Violence: Definitions and
Scope
Violence is broadly defined as the intentional use of physical force or
power, threatened or actual, against oneself, another person, or a
community, resulting in or with a high likelihood of resulting in injury,
death, psychological harm, maldevelopment, or deprivation. This
definition, established by the World Health Organization, encompasses a
wide spectrum of harmful behaviors that nurses encounter in various
clinical and community settings.
In public health nursing, violence is conceptualized across multiple
domains:
Interpersonal violence (between individuals)
Self-directed violence (suicide, self-harm)
Collective violence (social, political, economic)
Structural violence (systemic oppression, discrimination)
Violence manifests in numerous forms including physical assault, sexual
violence, emotional abuse, neglect, and human trafficking. Each form
requires specific assessment approaches and interventions. The nursing
role extends beyond treating physical injuries to identifying risk factors,
providing trauma-informed care, and connecting survivors with
appropriate resources.
Epidemiological data indicates that violence disproportionately affects
vulnerable populations, creating a cycle that perpetuates health
disparities. Understanding the full scope of violence enables nurses to
, 4
recognize both direct clinical presentations and upstream risk factors for
effective prevention and intervention strategies.
Community and Social
Drivers of Violence
Violence and abuse are
inextricably linked to social
determinants of health. These
include poverty, housing
instability, community
disorganization, unemployment,
and limited access to supportive
services. Recognizing these
relationships is essential for Public Health Nursing
developing effective public health Assessment
nursing interventions. As public health nurses, it is
essential to conduct
