Step-by-step explanation:
The nurse should address the client's risk of harm from polypharmacy by ensuring that the client's care is coordinated and encouraging the primary care provider to review the medication regimen.
Polypharmacy refers to the use of multiple medications by an individual, which can lead to an increased risk of adverse drug reactions, drug interactions, and medication nonadherence.
By coordinating the client's care and involving the primary care provider, the nurse can help minimize the risk of harm and ensure that the client's medication regimen is appropriate and optimized.
