What is the duty of a guardian in relation to the ward's physician?

The correct response emphasizes the guardian's responsibility to ensure that the ward's physician is kept informed of significant changes in the ward's health or condition. This duty is critical because effective medical care requires that physicians have the most current and comprehensive information about a patient’s status to make informed decisions regarding treatment.

When a guardian communicates changes in the ward's condition, they are facilitating proper medical oversight and helping the physician tailor their approach to meet the ward's current needs. This encourages a collaborative relationship between the guardian and the medical team, which is essential for the ward's health and safety.

The other options do not align with the fundamental responsibilities of a guardian. For instance, changing the ward's physician impulsively could disrupt care continuity, and a guardian is expected to work collaboratively rather than independently make unilateral decisions regarding medical treatment. Additionally, withholding information from the physician would impede the quality of care that the ward receives, countering the guardian's role as a protector and advocate for the ward’s well-being. Thus, the focus on communication with the physician underlines the guardian's essential role in supporting the ward's healthcare needs.
