Final answer:
Taking outdated prescriptions is a potential indicator of neglect of an older adult because it suggests a lack of proper care or supervision in medication management.
Step-by-step explanation:
The student is asking about an indicator of possible neglect of an older adult client during a home visit by a nurse. Among the listed options, taking outdated prescriptions can be seen as a potential sign of neglect. This is because it could indicate that the individual is not receiving proper care or supervision regarding their medication management. If an older adult is still using expired medications, it may suggest a lack of appropriate health oversight or inability to access current prescriptions, which is often an aspect of neglect.
It is important to recognize that while living alone or having alcohol in the home are not definitive indicators of neglect, and a Body Mass Index (BMI) of 25 falls within the normal weight range, the use of outdated prescriptions is a more concrete sign that the client's welfare might be at risk.
