Which of the following is signed by the attending physician?

A) Discharge summary
B) Hospital course
C) Discharge instructions
D) Discharge disposition

The discharge summary is typically signed by the attending physician, as it is a summary of the patient's hospital stay and includes information about their diagnosis, treatment, and any follow-up care that may be needed. The hospital course, discharge instructions, and discharge disposition may also be included in the discharge summary, but the attending physician's signature is usually required only on the summary itself.
