A nurse is teaching a client who has a history of substance abuse about prevention and education strategies. Which of the following statements by the client indicates a need for further teaching?

Correct answer: b) Count and document the remaining supply of medication

Rationale: Schedule III controlled substances are drugs that have a moderate potential for abuse and addiction and are subject to moderate regulations by the DEA. The nurse should count and document the remaining supply of medication every time they administer a Schedule III controlled substance to ensure accuracy and prevent diversion.

Incorrect choices:

a) Obtain a written prescription from the provider every time: This is not required for Schedule III controlled substances, as they can be refilled up to five times within six months by phone or fax. However, this is required for Schedule II controlled substances, which have a higher potential for abuse and addiction.

c) Dispose of any unused medication in a sharps container: This is not an appropriate way to dispose of any unused medication, as it can pose a risk of injury or infection to others. The nurse should dispose of any unused medication by using a DEA-approved disposal company or following the facility's policy.

d) Administer the medication only by intravenous route: This is not required for Schedule III controlled substances, as they can be administered by various routes depending on the formulation and indication. However, some Schedule II controlled substances, such as morphine or fentanyl, are administered only by intravenous route for acute pain management.

Correct answer: d) The amount and strength of medication

Rationale: The amount and strength of medication are not required to be documented in the MAR for Schedule IV controlled substances, as these are low-abuse potential drugs that have accepted medical uses. However, they are required for Schedule I, II, and III controlled substances, which have higher abuse potential and stricter regulations.

Incorrect choices:

a) The nurse's signature and initials: These are required to be documented in the MAR for all medications, including controlled substances, to ensure accountability and accuracy.

b) The date and time of administration: These are required to be documented in the MAR for all medications, including controlled substances, to ensure adherence to the prescribed schedule and avoid errors.

c) The route and site of administration: These are required to be documented in the MAR for all medications, including controlled substances, to ensure proper delivery and avoid complications.
