Final answer:
Self-administered medications for a resident should be stored in a locked and secure area, with access limited to authorized personnel to ensure safety and proper medication management.
Step-by-step explanation:
For medications that are self-administered by a resident, they must be stored in a secure area accessible only to authorized personnel, as indicated by option c. This ensures that the medications are handled safely and that the risk of misuse, theft, or accidental ingestion by others is minimized. The storage area should be locked and monitored, with the resident having access to their own medications under the supervision or guidance of authorized personnel to maintain proper medication management.
