Failing to knock on the door before entering a resident's room violates which of the following rights?

The correct choice emphasizes the resident's right to privacy. When a caregiver or any staff member fails to knock before entering a resident's room, it demonstrates a lack of respect for that individual's personal space and boundaries. Privacy is a fundamental aspect of healthcare that allows residents to feel safe and respected in their environment. By knocking, a caregiver gives the resident the opportunity to prepare for the interaction, which helps uphold their dignity and personal autonomy.

In the context of the options available, while the right to dignity and the right to safety are also important, they are not as directly related to the act of entering a private space without permission. The right to free movement pertains more to a resident's ability to move freely within the facility rather than issues of access to their personal living space. Therefore, the best answer reflects the specific violation of the resident's expectation of privacy in their personal area.
