A medical assistant is informed that a patient who is going to undergo elective orthopedic surgery requires additional cardiac and hematological assessments as per the surgeon's protocol. Which of the following actions is the most appropriate way to arrange for these pre-surgical assessments?
Organize for the patient to have the laboratory work done on the morning of the surgical procedure.
Instruct the patient to present at the laboratory on any day before the surgery without an appointed time, for the required testing.
Schedule the required cardiac and hematological assessments a week before the surgery and ensure the results are sent to the surgeon's office in advance.
Arrange for the patient's hematological tests to be done in-house while the cardiac examinations are completed at an external clinic on the day before surgery.
