A nurse is caring for a patient with Parkinson's disease who has been prescribed carbidopa/levodopa. The patient reports new onset of hallucinations and impulsive behaviors. Which nursing action is the most appropriate priority?

A. I will not bother to check the expiration date of my acetaminophen medication before taking it:Taking expired medications can reduce effectiveness or increase the risk of adverse effects. Checking the expiration date is an important safety practice.

B. OTC medications are safe enough not to need a doctor's prescription so taking a little more than the bottle says can help with severe pain:Exceeding the recommended dose of acetaminophen can lead to hepatotoxicity and liver failure. Following dosing instructions is essential for safety.

C. I will mix my acetaminophen with alcohol to enhance its pain-relieving effects:Alcohol combined with acetaminophen greatly increases the risk of liver damage. These substances should never be taken together.

D. I will check the labels of my other over-the-counter medications to ensure I am not consuming multiple products containing acetaminophen:Many combination cold, flu, or pain medications contain acetaminophen. Checking labels prevents accidental overdose, supporting safe use and demonstrating appropriate patient understanding.

A. Discard the medication and obtain a new one from the pharmacy:Medications past their expiration date may have reduced potency or unknown chemical changes, making them unsafe or ineffective. The correct and safe practice is to discard expired medication and obtain a current supply.

B. Administer the medication if the client has taken it before without issues:Previous tolerance does not guarantee safety or effectiveness of an expired medication. Administration could result in subtherapeutic effects or adverse reactions.

C. Check with another nurse if it's okay to administer:While collaboration is important, the ultimate responsibility is patient safety. Expired medications should not be administered under any circumstances, regardless of peer approval.

D. Continue with administration and notify the healthcare provider later:Administering an expired medication compromises patient safety. The healthcare provider should be informed beforeadministration if an alternative is needed, not afterward.
