10. You are reviewing a patient’s sputum culture results that have tested positive for Staphylococcus epidermidis. How do you interpret these findings?
The patient has a respiratory infection.
The patient’s sputum is no longer sterile.
This is part of the patient’s normal flora.
The results are inconclusive.
