  6. ECG:  P-, QRS-, T-waves are barely noticeable or absent.
    Asystole (demystified p. 56)
  7. Treatment & interventions for Myocarditis.
    • antiarrhythics (quinidine, procainamide)
    • limit activities
    • bedside commode
    • monitor for dyspnea (fluid overload)
    • monitor HR>100 (infection or inflammation)
    • return slowly to activities

    • coughing & deep breathing exercises
    • slowly resume daily activities
  10. Petecchiae on the palate, beneath the fingernails, osler nodes (painful, discolored, raised areas on fingers & feet), Janeway lesions (painful lesions on palms & soles). S/S of what?
    Endocarditis (Demystified p. 29)
  11. Treatment for endocarditis.
    Abx based on result of culture & send
  12. S/S of viral pneumonia.
    (Reviews & Rationales p. 79)
    • Low-grade fever
    • Non-productive cough
    • WBC normal to LOW
    • (less severe than bacterial)
  13. S/S of bacterial pneumonia. 
    (Reviews & Rationales p. 79)
    • HIGH fever
    • Productive cough
    • WBC HIGH
  14. Why isn't a chest tube usually used in a pt who had a lung tumor removed?
    (HESI p.72)
    So that the mediastinal cavity (where lung used to be) can fill with fluid to prevent the shift of organs into empty space
  15. Why would fluctuations (tidaling) in the fluid of a chest tube occur?
    (HESI p.72)
    • No external suction
    • good indicator that the system is intact
    • should move UP w/ inspiration & DoWN w/ expiration
  16. What to do if fluctuations in the fluid of a chest tube cease?
    (HESI p.72)
    • Check for: kinked tubing,
    • accumulation of fluid in tubing,
    • occlusions, or
    • change in pt's position
  17. What would make fluctuations (tidaling) in a chest tube cease?
    (HESI p.72)
    When EXTERNAL suction is applied
  18. What PO2 value indicates respiratory failure in adults?
    below 60
  19. What blood value indicates hypercapnia?
    PCO2 above 45
  20. Hypoxemia exists when PO2 is less than ____ and FiO2 is greater than _____.
    • 50 mmHg
    • 60%
  21. Interventions to prevent complications of pts on mech vent with ARDS.
    • HOB at least 30 degrees
    • Daily awakening (sedation vacation)
    • oral hygiene
    • mobilization
  22. PCO2 & PO2 values signifying resp failure.
    • PCO2>45 OR
    • PO2 < 60 on 50% O2

    (HESI p.30-31)
    • h/o MI w/ LV failure OR
