What Can a CNA Do and Not Do?

CNAs are considered the backbone of nursing. These healthcare workers often provide the majority of hands-on patient care duties that include assisting patients with bathing, grooming, dressing, helping with walking, transfers from one place to another, turning bed-bound patient position, feeding, toileting, and many other essential activities of daily living commonly termed ADLs.

A certified nursing assistant works under the supervision of an LPN, Vocational Nurse, or Registered Nurse depending on the facility or healthcare practice. A CNA may be more limited in the scope of their duties that they are allowed to legally perform depending on the location of the care setting.

State laws that oversee healthcare workers like CNAs can differ significantly. A CNA working in one state may be seen passing meds in assisted living environments, and CNAs working in another state may only be able to monitor or supervise capable patients as they take their own medications.

Can a CNA Do Wound Care?

No, open wound care is something RNs perform. They have the knowledge/skills to assess wound depth, type, and wound treatment, positive or negative changes. However, nurses rely on their CNAs to report changes in skin condition promptly if seen during patient showering, toileting, or dressing.

Can CNAs Take Blood Sugar?

Yes, some assisted living facilities allow CNAs to get patient blood sugar readings and perform blood glucose machine checks to ensure accuracy.
