Which of the following factors can significantly affect a resident's response to medication?

The resident's age and other health conditions play a crucial role in how they respond to medication. As individuals age, there are often physiological changes that can impact the metabolism and excretion of drugs. For instance, older adults may have decreased liver and kidney function, which can lead to slower processing of medications and an increased risk of side effects or toxicity. Furthermore, existing health conditions, such as diabetes, hypertension, or liver disease, can affect how a resident’s body interacts with medications, possibly requiring dose adjustments or alternative treatments to ensure safety and efficacy.

By taking into account the resident's overall health profile, including age and comorbidities, caregivers can tailor medication management to optimize therapeutic outcomes and minimize adverse effects. This personalized approach is essential in assisted living settings, where varied health statuses among residents necessitate careful consideration in medication administration.
