Certified Medical Assistant vs. Licensed Practical Nurse: Key Differences in Healthcare Roles

Last Updated Mar 5, 2025
By M Clark

Certified Medical Assistants (CMAs) perform administrative and clinical tasks in outpatient settings, supporting physicians by taking vital signs, preparing patients for exams, and managing medical records. Licensed Practical Nurses (LPNs) provide direct patient care, including administering medications, wound care, and monitoring patient health under the supervision of registered nurses or doctors. Both roles require certification and state licensing, but LPNs typically have more comprehensive clinical responsibilities and patient care duties.

Role Overview: Certified Medical Assistant vs Licensed Practical Nurse

Certified Medical Assistants (CMAs) perform clinical and administrative tasks such as patient preparation, vital signs measurement, and medical record management, supporting physicians in outpatient settings. Licensed Practical Nurses (LPNs) provide direct patient care including medication administration, wound care, and monitoring vital signs, primarily in long-term care facilities and hospitals. The CMA role emphasizes assisting with office procedures and patient flow, while the LPN role focuses on hands-on nursing care and clinical responsibilities.

Education and Certification Requirements

Certified Medical Assistants (CMAs) typically complete a one-year accredited postsecondary certificate or diploma program and must pass the American Association of Medical Assistants (AAMA) certification exam. Licensed Practical Nurses (LPNs) undergo more extensive education, usually a 12- to 18-month accredited practical nursing program, and must pass the National Council Licensure Examination for Practical Nurses (NCLEX-PN) to obtain licensure. The CMA certification focuses on administrative and clinical skills, while LPN licensure emphasizes practical nursing knowledge and patient care responsibilities.

Daily Duties and Responsibilities

Certified Medical Assistants perform clinical tasks such as taking vital signs, preparing patients for examinations, and administering injections, while also managing administrative duties like scheduling and maintaining medical records. Licensed Practical Nurses provide direct patient care including wound dressing, monitoring vital signs, administering medications, and assisting with personal hygiene under the supervision of registered nurses or physicians. Both roles require strong communication skills and the ability to work efficiently in fast-paced healthcare environments to support patient care.

Skills and Competencies Needed

Certified Medical Assistants (CMAs) require proficiency in clinical tasks such as taking vital signs, administering injections, performing EKGs, and managing patient records with electronic health systems. Licensed Practical Nurses (LPNs) demonstrate skills in direct patient care including wound care, medication administration, and monitoring patient health under RN supervision. Both roles demand strong communication, attention to detail, and knowledge of medical terminology to ensure quality patient care and support healthcare teams effectively.

Work Settings and Environments

Certified Medical Assistants (CMAs) typically work in outpatient settings such as physician offices, clinics, and outpatient care centers where they perform clinical and administrative tasks. Licensed Practical Nurses (LPNs) are commonly employed in long-term care facilities, hospitals, and nursing homes, providing direct patient care and monitoring vital signs. Both roles require adaptability to fast-paced healthcare environments, but LPNs often engage in more hands-on clinical responsibilities within inpatient settings.

Scope of Practice and Legal Limitations

Certified Medical Assistants (CMAs) perform administrative and clinical tasks such as patient preparation, basic laboratory tests, and immunizations under physician supervision, with a scope limited to non-invasive procedures. Licensed Practical Nurses (LPNs) provide direct patient care including medication administration, wound care, and monitoring vital signs, operating under the oversight of registered nurses or physicians in more extensive clinical settings. Legal limitations restrict CMAs from performing invasive procedures or independent nursing care, while LPNs have a broader scope but must adhere to state-specific regulations and supervision requirements.

Salary and Job Outlook Comparison

Certified Medical Assistants (CMAs) earn a median annual salary of approximately $39,000, while Licensed Practical Nurses (LPNs) typically make around $48,000 per year, reflecting differences in responsibilities and clinical training. Employment projections from the Bureau of Labor Statistics indicate a 18% growth rate for LPNs through 2031, outpacing the 19% growth projected for medical assistants, signaling strong demand in both roles but a slightly higher expansion rate for medical assistants. Job outlook variations are influenced by healthcare industry trends, with LPNs often having more opportunities in long-term care facilities and CMAs frequently employed in outpatient settings.

Career Advancement Opportunities

Certified Medical Assistants (CMAs) often advance their careers by specializing in areas like phlebotomy or medical billing, or by pursuing further education to become Registered Nurses (RNs). Licensed Practical Nurses (LPNs) have clearer pathways to higher nursing roles, frequently transitioning to Registered Nurse positions through bridge programs such as LPN-to-RN. The demand for RNs supports significant career growth for both CMAs and LPNs, with LPNs typically having more structured advancement opportunities within clinical settings.

Pros and Cons of Each Role

Certified Medical Assistants (CMAs) excel in administrative and clinical tasks such as patient scheduling, vitals collection, and assisting physicians, but they have limited scope in performing invasive procedures. Licensed Practical Nurses (LPNs) offer more hands-on patient care, including medication administration and wound care, with greater authority in clinical settings, though their role often entails longer schooling and state licensing requirements. CMAs typically experience more varied job duties with quicker certification, whereas LPNs enjoy expanded responsibilities but face stricter regulatory oversight and potentially higher stress levels.

Choosing the Right Path in Healthcare

Certified Medical Assistants (CMAs) perform administrative and clinical tasks supporting physicians, with training programs typically lasting 1 year and certification through the AAMA. Licensed Practical Nurses (LPNs) provide hands-on patient care under RN supervision, completing practical nursing programs in about 12 months and obtaining licensure via the NCLEX-PN exam. Choosing between CMA and LPN depends on career goals, with CMAs suited for clinic support roles and LPNs for direct patient care in settings like nursing homes and hospitals.
