Final answer:
The patient likely felt "on edge" due to the caregiver's lack of professionalism and confidentiality which can cause discomfort and anxiety.
Step-by-step explanation:
From the provided choices, behaviors that made the patient feel "on edge" likely refer to a lack of professionalism/confidentiality. In a caregiving setting, patients expect caregivers to maintain a professional demeanor that includes protecting their privacy and handling sensitive information with care. When caregivers display a lack of professionalism, such as showing disrespect, failing to maintain confidentiality, or engaging in untrustworthy behavior, it can make patients feel anxious and uncomfortable.
