Which of the following factors might indicate a lack of decision-making capacity in a patient?

A patient's lack of decision-making capacity is often assessed through various cognitive and situational indicators. One significant factor is the presence of orientation issues regarding person, place, or time. When a patient is not clear about their identity, their current location, or the time of day, it suggests potential disruptions in their cognitive processing. This disorientation can impair the individual's ability to understand the implications of their healthcare choices and effectively communicate their preferences.

In contrast, a clear understanding of treatment options indicates that the patient is engaging with their care and can make informed decisions. Recent attendance at a support group and stable medication adherence reflect positive behaviors and a potential capacity to understand and follow treatment protocols. Thus, orientation issues serve as a critical red flag in evaluating a patient's competence to make decisions about their care.
