The mother states she has treated the rash with a number of different lotions, but the lesions persist. She is looking for information on how to make her daughter stop licking her lips, as she thinks this is causing the lesions. Upon assessment, the nurse notes circumoral blisters and honey-colored crusts. In the medical history, the mother reports her daughter has not had any other symptoms, including fever, nausea, vomiting, and malaise.

A positive coagulase test indicates the presence of S.aureus infection, and the sample completely coagulating is indicative of this result. A negative coagulase test would show the sample remaining liquid. The sample turning yellow is not a characteristic of a coagulase test.
