A client is preparing for discharge after several medication changes. The verified preadmission list, inpatient MAR, and draft discharge prescriptions contain an unexplained omission and a possible duplicate therapy. Which medication-reconciliation actions are appropriate? Select all that apply.

Quick answer
Select comparison, authorized discrepancy resolution, documentation with an updated list, and teach-back.

Why this is correct
AHRQ describes medication reconciliation as obtaining and verifying an accurate history, comparing it with transition orders, resolving unintended discrepancies, and communicating the updated list. Teach-back checks whether the final plan was understood.

Easy analogy or mental picture
Reconciliation is a chain of custody: identify the list, compare it, resolve differences, document the final version, and hand it over with confirmation.

Memory hook
Compare, resolve, document, communicate, confirm.

NCLEX decision rule
Do not close a transition with unexplained differences. The nurse coordinates resolution but does not independently delete prescriptions or ask the client to choose between unresolved therapies.

Why the other choices are wrong
Deleting uncertain medications can omit necessary therapy. Asking the client to select between duplicate entries transfers a clinical decision to the client and preserves the hazard.
