Greatest risk for Parenteral nutrition - Answer: long term - cholestasis
short term-infection
name alcohol toxicity
-high osmolar gap
-slurred speech, unsteady gait, altered mentation - Answer: Alcohol ketoacidosis
name alcohol toxicity
-high osmolar gap
-visual blurring, afferent pupillary defect, altered mentation - Answer: Methanol ingestion
name alcohol toxicity
-high osmolar gap
-calcium oxalate crystals - Answer: Ethylene glycol ingestion
name alcohol toxicity
-high osmolar gap
-CNS depression, disconjugate gaze, absent ciliary reflex - Answer: Isopropyl alcohol ingestion
,Pt just received chemotherapy presents with painless ulcer with black center
-what is the cause - Answer: pseudomonas aeruginosa due to immunocompromised state
Pulses paradoxus - Answer: AKA as paradoxical pulse. The paradax is that the apical pulse can
still be heard even though the radial pulse is no longer palpable. It is measured by using the
blood pressure cuff and stethoscope.
Beck's triad for cardiac tamponade. - Answer: (1) HYPOTENSION
(2) MUFFLED or DISTANT HEART SOUNDS
(3) JUGULAR VENOUS DISTENSION (JVD)
***Physical Exam: Tachycardia, Hypotension+++, PULSUS PARADOXUS (↓ in systolic BP on
inspiration >10mm Hg).
Tx: PERICARDIOCENTESIS
most common cause of infectious myocarditis and pericarditis - Answer: coxsackievirus
subacute bacterial endocarditis - Answer: Alpha-hemolytic streptococci from mouth
fever, HA, seizures, confusion and stupor that occurs over the course of a few days
-abnormalities in the frontotemporal region
most common cause - Answer: Herpes simplex virus
, CSF findings of HVS encephalitis - Answer: -lymphocytic pleocytosis
-elevated RBC count -normal glucose
destruction of frontotemporal lobes
restricted lung disease pattern - Answer: <80% of predicated FEV1, FVC, and total lung capacity
-normal or increased FEV/FVC ratio
neurogenic claudication - Answer: lumbar spinal stenosis--> nerve irritation --> burning electric
type pain with numbness and paresthesias of the lower extremities
MRI can confirm diagnosis
most common cause of paraneoplastic Cushing syndrome - Answer: small lung cancer
Medication shown to significantly reduce the risk of embolization in pt with AF who are
moderate to high risk of thromboembolic events - Answer: Rivaroxaban
do not confuse with aspirin, clopidogrel if they are on the choices
Light criteria for exudate - Answer: Pl fluid protein/serum protein = >0.6
pl fluid LDH/serum LDH = >0.6
pl fluid LDH >2/3 upper limit of normal for serum LDH
-infection, malignancy, PE
light criteria for transudate - Answer: Pl fluid protein/serum protein = <0.6
