Preventative measures (aside from handwashing) of HAI? Answer: early
removal of invasive devices or lines
limit spectrum of antibiotic coverage and unnecessary duration to
prevent multidrug resistance
What are indications for line removal? Answer: -purulence at insertion
site
-S.areus, candida, or gram neg rods
-persistent bacteremia (>48hr on abx)
-complications (thromboemboli)
What is empiric antibiotics Answer: vanco for MRSA
consider gram neg coverage for immunocompromised/critically ill
treatment if patient presents with UTI symptoms and a foley present
Answer: -remove foley
-treat with 7 days abx specific to culture results
-treat for 14 days if fever, back pain, leukocytosis, or suggest
pyelonephritis

Treatment for SSI? Answer: most common pathogens postop wound
infection are: S.Areus, coagulase-neg staph.
Tx: opening wound, drainage, debriding, culturing, and antibiotics
empiric coverage driven for gram stain for patients with SSI include?
Answer: MRSA- vanc
(linezolid if vanc allergy)
s/s, evaluation, and management of cholecystitis: Answer: S/s:
RUQ/epigastric pain, fever, nausea, vomiting, murphy sign
eval: blood cultures, RUQ US, amylase, lipase
mgt: admission to hospital, cholecystectomy, antibiotics
