This is a study guide for Methicillin-Resistant Staphylococcus Aureus (MRSA) which includes its nursing management, nursing assessment, selected nursing diagnoses, and nursing interventions. Show
Staph infections—including those caused by MRSA—can spread in hospitals, other healthcare facilities, and in the community where people live, work, and go to school.
PathophysiologyStaphylococcus aureus is a gram-positive coccus that is both catalase- and coagulase-positive.
Statistics and IncidencesUp to 80% of people are eventually colonized with Staphylococcus aureus. Most are colonized only intermittently; 20-30% are persistently colonized.
CausesPredisposing factors for staphylococcal infections include the following:
Clinical ManifestationsThe symptoms of an MRSA infection depend on the part of the body that is infected.
Assessment and Diagnostic FindingsMethicillin-resistant Staphylococcus aureus (MRSA) is resistant to all β-lactams because of the presence of mecA, a gene that produces a pencillin binding protein (PBP2a) with low affinity for β-lactam antibiotics.
Medical ManagementCDC encourages clinicians to consider MRSA in the differential diagnosis of skin and soft tissue infections (SSTIs) compatible with S. aureus infections, especially those that are purulent (fluctuant or palpable fluid-filled cavity, yellow or white center, central point or “head,” draining pus, or possible to aspirate pus with needle or syringe).
Pharmacological ManagementSeveral antimicrobial agents have been proposed as alternatives to beta-lactams for outpatient treatment of SSTIs when an oral regimen with activity against MRSA is desired; these include clindamycin, tetracyclines (including doxycycline and minocycline), trimethoprim-sulfamethoxazole (TMP-SMX), rifampin (used only in combination with other agents), and linezolid.
