Final answer:
The medical office assistant should create an addendum connecting the new information about the streptococcal infection to the original note.
Step-by-step explanation:
The medical office assistant should choose option D: Create an addendum because the new information must be connected to the original note.
When the sputum culture indicates a streptococcal infection, it is important to update the patient's medical record with this new information. Creating an addendum allows for accurate documentation and ensures that all relevant information is connected to the original note. This is crucial for providing effective treatment and continuity of care for the patient.
By creating an addendum, the medical office assistant can maintain the integrity of the original note while including the updated information about the streptococcal infection. This provides a complete and accurate picture of the patient's condition and allows for appropriate treatment decisions to be made.
