Only who can dispose of controlled substances?

• A. The pharmacist
• B. The patient
• C. The delegating nurse
• D. The supervising physician

Answer: (C)

Disposal of controlled substances must be handled by a person who has the authority to supervise the process and document it, ensuring strict accountability. The nurse who has been delegated responsibility for the medication is the one equipped to initiate and oversee disposal, verify the exact amount being wasted, ensure it’s witnessed if required, and record the disposal in the patient’s chart and disposal logs. This setup protects against diversion and keeps everything compliant with regulations. The patient cannot dispose of meds themselves, and while pharmacists or physicians may be involved in policy or oversight, the on-the-spot disposal is typically the responsibility of the delegating nurse who has the authority to approve and document the waste.
