W - water (UTI)
W - wound (wound infection)
W - walking (DVT/thrombophlebitis)
W - wonder drugs (drug fever)
If the post op fever occurs within the first 24 hours of surgery, what is the most likely cause? -
answerwind/atelectasis
If the post op fever occurs within days 3-5 post op, what is the most likely cause? - answer-water/UTI,
catheter related phlebitis, pneumonia
If the post op fever occurs within days 5-10 post op, what is the most likely cause? - answer-wound
infection, pneumonia, abscess, infected hematoma, C diff colitis, anastomotic leak, DVT, peritoneal
abscess, drug fever, PE, parotitis
_______is the most common pathogen in wound infections and around foreign bodies. - answer-Staph
aureus
_______invades the inner ear and enteric tissues as well as the lung. - answer-Klebsiella
______organisms are often found together with anaerobes. - answer-Enteric organisms ie.
enterobacteriaceae and enterococci
Among the anaerobes, ___&___are often present in surgical infections and _____species are major
pathogens in ischemic tissue. - answer-Bacteroides & Peptostreptococci; Clostridium
Some fungi and yeast cause abscesses in sinus tracts. - answer-Pseudomonas & Serratia
, History of recent surgery, trauma, cancer, prolonged immobilization, or oral contraceptive use increases
the risk of ____. - answer-DVT - deep vein thrombosis
What is Homan's sign? - answer-pain on passive dorsiflexion of ankle
What is the test of choice for DVT? - answer-doppler ultrasound
How is the D-dimer text useful? - answer-It is good at ruling a DVT out (if the text is negative) but not
rule it in
The most common cause of SIRS (systemic inflammatory response syndrome) is sepsis. What are the

water and sodium while dehydration is loss of intracellular water or deficit with hypernatremia --
dehydration occurs when patient can not adjust water intake for water loss
What are the clinical signs of dehydration and hypovolemia? - answer-tachycardia, hypotension, pale
skin, increased capillary refill time, dizziness, faintness, nausea, thirst, decreased urine output -- in
hypovolemia, urine will demonstrate low sodium concentration
