Who must review each resident's drug regimen at least once a month?

The correct answer highlights the role of a licensed pharmacist in reviewing each resident's drug regimen at least once a month. This practice is essential for ensuring medication safety and efficacy in healthcare settings, particularly in facilities like nursing homes or long-term care facilities.

A licensed pharmacist is specifically trained to understand pharmacology, assess medication interactions, and monitor for potential side effects. By regularly reviewing drug regimens, pharmacists can identify issues such as unnecessary duplications, contraindications with other medications, or dosage adjustments that may be necessary due to a resident's changing health status. This proactive engagement in medication management plays a crucial role in optimizing therapeutic outcomes and minimizing the risks of polypharmacy.

While other healthcare professionals, including the medical director or nursing staff, have important roles in patient care and overseeing clinical practices, it is the licensed pharmacist who possesses the specialized training and depth of knowledge in medication management required to conduct monthly reviews of residents’ drug regimens effectively. This ensures a comprehensive, collaborative approach to patient care where the best possible therapeutic paths can be determined.
