Final answer:
Certified Nursing Assistants (CNA) and Licensed Practical Nurses (LPN) perform delegated nursing tasks under the supervision of a licensed nurse, differentiating them from RNs and NPs who have more independent roles.
Step-by-step explanation:
Individuals who perform delegated nursing tasks under the supervision of a licensed nurse are typically: Certified Nursing Assistants (CNA) and Licensed Practical Nurses (LPN). Registered Nurses (RN) and Nurse Practitioners (NP) have a broader scope of practice and are not considered to perform delegated tasks as they are licensed to carry out more complex and independent roles. CNAs and LPNs contribute to patient care by performing tasks as directed by RNs or other higher-licensed nurses following nursing regulations and state laws.
