An 82-year-old client with multiple chronic conditions is taking 12 different medications. The nurse is conducting a medication safety assessment. Which nursing action is the MOST important priority to prevent adverse drug events in this older adult client?

For an 82-year-old client taking 12 different medications, the risk of adverse drug events (ADEs) is exponentially increased due to polypharmacy. While all the listed actions are valuable components of a comprehensive care plan, the nurse's most important priority is to first establish a complete and accurate picture of what the client is actually taking. This is achieved through a comprehensive medication reconciliation and review. This foundational step directly addresses the primary source of potential harm: unidentified drug interactions, inappropriate medications, and therapeutic duplications. Without this critical analysis, actions like education, pill organizers, or more frequent appointments are built on a potentially flawed and unsafe medication list.

The systematic review by Zavaleta-Monestel et al. confirms that polypharmacy is directly associated with medication-related harm, including adverse drug events and drug-drug interactions ^[1]. A comprehensive review is the proactive clinical activity that identifies these risks before they translate into patient harm. The review by Ucarer et al. further supports this by highlighting that a hospitalization or clinical encounter represents a critical opportunity to optimize medication therapy through Quality Use of Medicines (QUM) activities, which are rooted in a thorough review of the patient's current regimen ^[2].

The other options, while important, are secondary because they are interventions that should follow, not precede, a safety review:

• Option 1 (Educate on adherence): Educating a client to take medications "exactly as prescribed" can be dangerous if the current prescription list includes inappropriate or interacting drugs. The priority is to ensure the prescription list is safe first. The concept of deprescribing, highlighted by Matos and Pinheiro, emphasizes the role of clinicians in discontinuing medications that no longer benefit the patient or are causing harm, which is a direct outcome of a thorough review ^[3].


• Option 2 (Pill organizer): A pill organizer is a strategy to improve medication compliance, but it does nothing to address the clinical appropriateness of the 12 medications. It may simply make it easier for the client to take a harmful drug combination.


• Option 4 (More frequent appointments): Scheduling more appointments without first optimizing the medication list misses the immediate opportunity to prevent an ADE. The qualitative study by Yang et al. identifies that implementing deprescribing and medication optimization faces significant real-world challenges, meaning simply seeing the patient more often does not automatically translate into a safer medication regimen without a structured review process .

The NCLEX-RN examination frequently tests the concept of prioritization using the nursing process. In this scenario, the nurse is in the assessment phase. A comprehensive medication reconciliation is the critical assessment action that gathers data about all substances the client is taking (prescriptions, over-the-counter drugs, supplements) and analyzes them for safety. This directly aligns with the findings of Zavaleta-Monestel et al., whose systematic review evaluated the effectiveness of pharmacist-led deprescribing interventions, a process that fundamentally begins with a thorough medication review to identify inappropriate prescribing and potential drug-drug interactions ^[1]. The review by Ucarer et al. reinforces that hospitalization or a clinical assessment is a key "opportunity to optimise medication therapy," and this optimization is impossible without first conducting the reconciliation and review to understand the baseline ^[2].

Matos and Pinheiro further clarify the nurse's crucial role, stating that as clinicians responsible for close patient monitoring, nurses contribute to the appropriate use of medications and the proper discontinuation of harmful ones ^[3]. This responsibility begins not with education or compliance aids, but with a critical safety assessment of the medication list itself. The challenges to implementing such a review, including patient resistance and systemic barriers, are well-documented by Yang et al., which underscores why the nurse’s deliberate, prioritized action to conduct this review is so vital . By identifying a potentially inappropriate medication or a major interaction, the nurse can prevent an adverse event such as a fall from hypotension, acute kidney injury, or a dangerous bleed—harms that are far more immediate and severe than non-adherence.
