It’s not uncommon for someone interested in nursing to pursue their CNA certification as a starting point. CNAs often work in the same places as PNs or RNs, such as hospitals, long-term care facilities, and clinics, but their duties are more limited due to their limited training and education as compared to nurses. Typically, CNAs help their patients with the nonmedical basics, like bathing, dressing, and eating. They also handle some medical tasks such as taking a patient’s temperature, weight, or blood pressure. Other nurses may handle tasks like bathing and dressing, too, but they have more job flexibility and responsibility than CNAs due to their higher level of training. The desire for increased responsibility is often the reason someone with a CNA certification decides to go back to school to be able to advance their career path in healthcare.
