Which factor would necessitate delaying a patient's surgery?

Delaying a patient's surgery is often essential when there is an uncontrolled medical condition. Uncontrolled medical conditions, such as unmanaged hypertension, diabetes, or infections, can significantly increase the risk of complications during and after surgery. These conditions can affect the body’s ability to heal, respond to anesthesia, and manage postoperative recovery. Therefore, it is critical to stabilize any uncontrolled medical issues before proceeding with surgical intervention to ensure the safety and well-being of the patient.

The presence of a supportive family member can have a positive influence on the patient's emotional well-being but does not necessitate delaying surgery. Completed preoperative assessments indicate that the patient is prepared for surgery, while recent routine lab results are typically informative and can facilitate timely decisions, rather than warranting any delay.
