Which task is most appropriate for an LPN/LVN to perform under the supervision of an RN?

LPN/LVN scope of practice is more limited than RN scope. The RN is responsible for INITIAL assessments, developing care plans, and providing initial teaching. The LPN's role is to REINFORCE existing teaching, contribute to data collection, and provide care within established plans. Key LPN scope principles tested on NCLEX-PN: (1) Cannot perform initial assessments of unstable or complex clients (LPN can reassess stable clients); (2) Cannot create the initial nursing care plan (LPN contributes data, RN creates plan); (3) Cannot provide initial teaching (LPN reinforces RN's teaching); (4) Cannot administer IV push medications in most states (state-specific); (5) Cannot perform triage independently in most settings; (6) Cannot hang blood (in most states); (7) CAN administer most medications, perform routine procedures, monitor stable clients, reinforce teaching, document care. Scope varies by state — when in doubt on NCLEX-PN, choose the answer that keeps the LPN within the traditional supportive role under RN supervision.
