What is the primary distinction between purulent and non-purulent SSTIs in terms of management?
What is the primary distinction between purulent and non-purulent SSTIs in terms of management?
- Purulent SSTIs always require systemic antibiotics, while non-purulent SSTIs do not.
- Non-purulent SSTIs are treated with topical agents and purulent SSTIs are not.
- Purulent SSTIs often necessitate incision and drainage, whereas non-purulent SSTIs are typically treated with antibiotics. (correct)
- Non-purulent SSTIs are primarily managed with incision and drainage, while purulent SSTIs require antibiotics.
What is the relevance of considering Staphylococcus aureus in the context of purulent SSTIs?
What is the relevance of considering Staphylococcus aureus in the context of purulent SSTIs?
- _Staphylococcus aureus_ is a rare cause of purulent SSTIs and does not significantly impact treatment decisions.
- Distinguishing between methicillin-susceptible _Staphylococcus aureus_ (MSSA) and methicillin-resistant _Staphylococcus aureus_ (MRSA) will influence the antibiotic selection. (correct)
- _Staphylococcus aureus_ primarily causes non-purulent SSTIs, making its consideration irrelevant in purulent infections.
- Neither MSSA nor MRSA is likely responsible for SSTIs.
