    40 mg IV
  18. What group of patients should receive diuretic treatment with ADHF?
    Wet = volume overloaded
  19. What are the CIs to diuretic use in ADHF?

  26. How should you monitor an ADHF patient on Diuretics?
    • Volume status
    • Daily ins and outs
    • Side effects
    • Symptomatic hypotension
  27. What is the fluid reduction goal at 2 hours of therapy?

    NG
  32. What are the adverse effects of NG in ADHF?
    Tachyphylaxis, HA, reflex tachycardia
  33. What are the hemodynamic effects of NG?
    • Decrease venous LV filling pressure = Decrease Preload
    • Increase arterial stroke volume and CO = Decrease Afterload
  34. If an ADHF patient w/ low CO has SBP > or = 90, what inotropic agent would you use?
    • On BB chronically: Milrinone
    • Not on BB chronically: Dobutamine
  35. If an ADHF patient w/ low CO has SBP <90, what inotropic agent would you use?
    Dobutamine
  36. If an initial Dobutamine or Milrinone treatment for an ADHF patient with Low CO is not sufficient, what other options could you add on?
