ACTUAL EXAM
A patient has CSF leaking from their nose after a transsphenoidal hypophysectomy,
what do you do? - ✔✔✔ANSWER-It is normal to have a CSF leak for 48 hrs after
surgery. Cover with a sterile "moustache" 2x2 tapes under their nose to form a
barrier.
If your dura is not intact that you would expect a leak, but it does increase your
risk of infection
,A pneumothorax caused by the ventilator is what? - ✔✔✔ANSWER-Result of
barotrauma- the vent pushes air into the pleural space with each breath and because
the parietal pleura is not open (like with a puncture) there is no where for the air to
go- so you get a tension pneumothorax
A simple way to estimate CVP is to add 5 cm to the measured height that the
jugular veins are distended above the sternal angle (angle of Louis) with the patient
in a 45-degree angle - ✔✔✔ANSWER-
ACE-I can cause what electrolyte imbalance? - ✔✔✔ANSWER-Hyperkalemia-
Prevent angio 1 from converting to angio II. Angio II usually blocks aldosterone
and cause vasoconstriction. Aldosterone usually holds on to Na and H2O in
exchange for K (excretes it), but since you don't have it you get rid of Na and H20
and hold on to K
Actual problems are worse than potential problems!! - ✔✔✔ANSWER-
Advantages of an IABP vs pressors? - ✔✔✔ANSWER-If you have a hypotensive
patient with high afterload giving them pressors will increase SVR, work on the
heart, and myocardial oxygen consumption. IABP increases coronary artery
perfusion and myocardial oxygen without increasing afterload or decreasing BP
Anterior wall MI - ✔✔✔ANSWER-V2, V3, V4
Bleeding time is a reflection of what? - ✔✔✔ANSWER-Platelet function.
Clopidogrel and abciximab are specifically platelet aggregation inhibitors. Heparin
is an indirect thrombin inhibitor, but it also inhibits platelet aggregation
BNP is secreted in response to? - ✔✔✔ANSWER-Ventricular wall stretch
, Diastolic murmurs are always pathologic. Systolic murmurs can be pathologic
(related to valve disease or septal defects) or they can be functional related to
turbulence of blood flow - ✔✔✔ANSWER-
Dobutamine is the drug of choice for cardiogenic shock - ✔✔✔ANSWER-Beta-
adrenergic stimulant, increases HR and contractility
Drugs that may cause torsades de pointes - ✔✔✔ANSWER-Amitriptyline (Elavil)
causes QT interval prolongation and may cause torsades . Other drugs- Class IA
antidysrhythmics (e.g., procainamide, quinidine, and disopyramide), Class III
antidysrhythmics (e.g., sotalol and amiodarone), tricyclic antidepressants (e.g.,
imipramine [Tofranil]), and phenothiazines (e.g., chlorpromazine [Thorazine])
Every 1 inch increase in abdominal girth equates to how much blood accumulation
in the abdomen - ✔✔✔ANSWER-500-1000mL
Giving a malnourished patient adequate nutrition may result in what electrolyte
disturbance? - ✔✔✔ANSWER-Severe phosphate deficiency. This often is called
refeeding syndrome. Nutritional support allows the cells to begin making more
adenosine triphosphate (ATP), and phosphate supplies are depleted. The same thing
happens in diabetic ketoacidosis with treatment when insulin allows glucose to
move into the cell increasing production of ATP and depletion of phosphate.
How can you differentiate the cause of jaundice? - ✔✔✔ANSWER-An increase in
direct bilirubin is associated with biliary obstruction because direct bilirubin is
conjugated. An increase in indirect bilirubin is associated with hepatic disease or
excessive hemolysis because indirect bilirubin is unconjugated
