Final answer:
To determine the principal procedure, we need to consider the procedure that is most significant and responsible for the reason the patient was admitted to the hospital.
Step-by-step explanation:
The principal procedure refers to the main procedure that is performed during a hospital admission. To determine the principal procedure, we need to consider the procedure that is most significant and responsible for the reason the patient was admitted to the hospital. The other procedures performed during the admission are considered secondary procedures.
Without specific information about the procedures involved, it is difficult to determine the principal procedure. It would be helpful to know the specific procedures performed so that we can assess their significance and relevance to the patient's condition.
Once we have the information about the procedures, we can evaluate their impact on the patient's condition and identify the procedure that is most central to their care as the principal procedure.
