A patient presents with symptoms of pneumonia. A sputum culture identifies the infectious agent as bacterial in nature and the patient is placed on IV antibiotics. Within 48 hours, the patient's vital signs return to normal, the patient has switched to oral antibiotics, is drinking fluids normally, and has had two formed bowel movements. The patient asks the nurse, When may I go home? Based on the patient's condition, what is the best response by the nurse?

a) You need to stay until the antibiotics are completed.
b) I will check with the doctor and let you know.
c) You may be discharged today if everything continues to improve.
d) It's too early to determine, as we need to monitor your progress.
