Healthcare Assistant (HCA) Roles and Responsibilities: Comprehensive Overview

Healthcare Assistants (HCAs), also known as Nursing Assistants or Patient Care Technicians, are frontline caregivers providing direct, hands-on patient care under the delegation and supervision of registered nurses.

• Feeding assistance; monitoring intake

2. Vital Signs and Monitoring

• Measure and record: temperature, pulse, blood pressure, respiratory rate, SpO₂, pain score, weight, blood glucose (point-of-care)
• Recognize and report abnormalities immediately (e.g., BP <90/60, HR >120, SpO₂ <92%, acute confusion)
• Neurovascular checks (post-op, casts)

3. Specimen Collection

• Urine (clean-catch, catheter specimen), stool, sputum
• Capillary blood glucose; venipuncture only if trained and authorized per facility policy

4. Basic Wound Care

Scope Boundaries

HCAs do not perform: nursing assessment, care planning, medication administration (generally), IV therapy, sterile procedures, teaching new diagnoses, or independent clinical judgment. These are RN responsibilities.

Professional Development

• CNA certification (state registry)
• CEUs for renewal (typically 12–24 hrs/2 yrs)
• Specialty certifications: dementia, wound, restorative, palliative
• Pathway to LPN/RN via bridge programs

HCAs are indispensable to patient-centered care. Clear role delineation, adequate staffing, and respect for their contributions are essential for safe, high-quality healthcare.
