What is factor V's role in the clotting cascade? ---------CORRECT ANSWER-----------------procoagulant clotting factor that amplifies the production of thrombin, the central enzyme that converts fibrinogen to fibrin A small amount of thrombin at the site of a wound activates factor V by limited proteolysis. Works as a positive feedback loop What is occuring in Factor V Leiden that leads to increased risk of VTE? --- ------CORRECT ANSWER-----------------a single point mutation of the factor V gene leads to factor V being insensitive to protein C (which is a natural anticoagulant) What anti-nausea medication is suggested for treatment of concussion?

What should be given along side the antibiotics while treating empirically? ---------CORRECT ANSWER-----------------IV works best to help better penetrate the BBB. Give dexamethasone while organism is unknown. Intravenous administration of glucocorticoids (usually dexamethasone) prior to or at the time of administering antibiotics has been associated with a reduction in the rate of hearing loss, other neurologic complications, and mortality in patients with meningitis caused by S. pneumoniae

(WBCs may be as much as 1000+) ---------CORRECT ANSWER--------------- --bacterial meningitis (will also see elevated glucose and maybe elevated protein)

Can help distinguish between thrombosis and embolus Where are arterial emboli often found? ---------CORRECT ANSWER---------- -------lower extremities more common than upper extremities The common femoral, common iliac, and popliteal artery bifurcations are frequent locations majority originate in the heart fun fact: Compared with thromboemboli, atheroemboli are less likely to produce symptoms of acute limb ischemia how would you work up a patient with treatment resistant hypertension that you suspect a secondary cause? ---------CORRECT ANSWER----------------- 24 - hour ambulatory monitoring (to ensure not white coat) medical hx (assess adherence to meds, other meds) physical exam (look for abominal/renal bruits) labs (electrolytes, glucose, creatinine, UA) If pheo suspected: measure fractionated metanephrines and catecholamines in a 24-hour urine collection other than atherosclerosis leading to renal artery stenosis and secondary HTN, what is another causes of a renal-associated secondary HTN? --------
when is it okay to do screening survelliance for AAA rather than repair and how often should you screen? ---------CORRECT ANSWER-----------------if AAA is <5.5 cm then annual screening with US is recommended. may need every 6 months if rapidly expanding or other concerns how should you educate a patient with AAA on exercise? ---------CORRECT ANSWER-----------------Patients should be counseled that moderate physical activity such as running, biking, swimming, hiking, or sexual activity and activities such as gardening, golfing, and horseback riding do not precipitate AAA rupture Moderate physical therapy may also limit aneurysm expansion. In experimental aneurysms, increased aortic blood flow appears to inhibit AAA expansion However, heavy lifting, especially while holding the breath, and other activities that lead to Valsalva transiently induce significant increases in blood pressure and should be avoided gold standard for dx renal artery stenosis? what can be used to monitor disease progression? ---------CORRECT ANSWER-----------------renal arteriography But really a spiral CT angiography is very useful and probably more likely done first duplex doppler US can be used to monitor disease progression what are some symptoms of mitral valve prolapse syndrome? --------- CORRECT ANSWER-----------------various nonspecific symptoms such as palpitations, dyspnea, exercise intolerance, anxiety disorders, and dizziness
