  1. What are the three most common causes of Metabolic Acidosis?
    ARF, Lactic Acidosis & DKA
  2. Why is diastolic BP so important?
    It shows what the capillary blood flow is.
  3. What is pulse pressure a measurement of?
    Left ventricular performance
  4. What is the renal dose of Dopamine?
    Trick question- there is no renal dose. 2.5mcgs is a vasodilating dose.
  5. What happens to HR and ECG in a RCA- IWMI(Inferior wall MI)?
    Bradycardia and Heart block
  6. What determines Ventricular Function?
    Preload, Contractility and Afterload
  7. What should you think when you hear a S3 heart sound?
    Emergency- patient if volume overloaded
  8. What should you think when you hear a S4 heart sound?
    Every person who has a MI will have this sound but it can only be heard when the patient is in SR
  9. What is normal PA pressure?
    20-25/8-12
  10. What is the normal Wedge(PWCP)?
    4-12
  11. What is normal CO?
    4-8 L/min
  12. What is normal CI?
    2.5-4 L/min
  13. What is normal CVP?
    2-6
  14. What determines SVO2?
    CO/CI, H&H, Oxygenation and Metabolic Demand
  15. What leads should be monitored?
    Lead II and MCL1 or V1
  16. Why should you monitor 2 leads?
    Location and "p"wave analysis
  17. What ECG changes appear in Hypokalemia?
    Flat T wave with prominent U wave, ST segment flattening, Prolonged QT interval and ST segment depression
  18. What ECG changes appear in hyperkalemia?
    • ASYSTOLE!
    • If:
    • >5.5- tall, narrow, peaked Twaves
    • >6.5- QRS widens
    • >8- Wide QRS and P wave barely visable
  19. What is the treatment for Hyperkalemia?
    • Remove= Kayexelate or HD
    • Shift K= insulin and D50, NaHCO and Ca
    • The calcium is given to protect the heart
  20. What ECG changes appear in hypocalcemia?
    • Prolonged QT and Prolonged ST segment
    • Torsades de Pointes
  21. What ECG changes appear in hypercalcemia?
    • agonal or asystole
    • Shortened QT and ST segment
  22. What ECG changes appear in hypomagnesaemia?
    • Torsades de Pointes
    • -prolonged QT
    • -broad, flattened Twave
    • - dysrhythmias
  23. What ECG changes appear in hypermagnesaemia?
    • agonal to asystole
    • -PR, QT prolonged
    • -prolonged QRS
  24. What is CAD?
    Flow limiting lesions
  25. What is the number 1 risk factor for CAD?
    Diabetes
  26. What are the clinical manifestations of CAD?
    HF, Angina, Unstable Angina, AMI, Sudden death
  27. What are the functions of an IABP?
    • Decreases afterload
    • Increases coronary perfusion
    • So in increases myocardial oxygen supply and decreased demand
  28. What is an absolute contraindication for an IABP?
    Aortic Insufficency
  29. What do you monitor for with an IABP?
    • Vascular exam
    • Timing
  30. What are the 6 P's of the vascular assessment?
    • Pain
    • Pulse
    • Pallor
    • Polar
    • Paresthesia
    • Paralysis
  31. On an ECG what leads show an inferior MI?
    II, III, and AVf
  32. How is a STEMI diagnosed?
    Clinical presentation, ECG, enzymes
  33. What does ST elevation in all leads mean?
    Pericarditis
  34. What are the clinical presentations of Left Ventricular failure?
    • Tachycardia
    • Tachypnea, dyspnea, orthopnea, PND
    • Left sided S3
    • Displaced MPI
    • Cough
    • Oliguria
    • Weakness, fatigue
    • Mental confusion
    • Murmur MR
  35. What are the clinical presentations of Right ventricular failure?
    • JVD
    • HJR
    • Dependent edema
    • Heave at sternum
    • Hepatomegaly
    • Anorexia, nausea, vomiting, abd pain
    • Ascites
    • Nocturia
    • Weakness, fatigue
    • Weight gain
    • Murmur TR
    • Right sided S3
  36. What is the management of an Aortic aneurysm?
    • Control BP
    • Repair- stent or surgical
  37. What does a ST segment depression show?
    Ischemia
  38. What does an ST segment elevation show?
    Current of injury
