what is the treatment for central retinal artery occlusion?
ocular massage and 100% oxygen

- low PaCO2: primary respiratory alkalosis and respiratory compensation for metabolic acidosis
- low HCO3-: primary metabolic acidosis and metabolic compensation for respiratory alkalosis
- arterial pH usually in the normal range: the two primary acid-base disturbances shift the pH in opposite directions
what is the triad of presenting symptoms in salicylate toxicity?
- fever

what is confirmatory for diagnosing mixed cryoglobulinemia?
circulating cryoglobulins
the majority of patients with mixed cryoglobulinemia have what underlying condition?
HCV
what nonpharmacologic intervention is most likely to have the greatest impact on hypertension?
- weight loss to BMI under 25
- DASH diet if BMI is already under 25
what ventilator setting improves mortality in ARDS?
low tidal volume ventilation (LTVV)
patients with ARDS require mechanical ventilation with which two primary goals?
- low tidal volume ventilation to prevent over-distension
- adequate oxygenation (with PEEP)
what is the most common ocular manifestation of temporal arteritis?
anterior ischemic optic neuropathy
what are the Light criteria for exudative pleural effusion?
at least one of:
- pleural fluid / serum protein ratio over 0.5

what is the acute treatment for cocaine toxicity?
benzodiazepines to alleviate psychomotor agitation and sympathomimetic effects (tachycardia, hypertension)
how is cocaine-induced acute coronary syndrome managed?
