After CABG these are some Nursing Diagnosis:
Decreased cardiac output r/t dysrhythmia, depressed cardiac function, increased systemic vascular resistance.
Deficient fluid volume r/t intraoperative fluid loss, use of diuretics in surgery.
Fear r/t outcome of surgical procdure.
One Intervention that comes to mind is:
Monitor for symptoms of heart failure and decreased cardiac output, including diminished quality of peripheral pulses, cool skin and extremities, increased respiratory rate, presence of aroxysmal nocturnal dyspnea or orthopnea, increased heart rate, neck vein distention, decreased level of consciousness, and presence of edema.
Hope this helps. Good luck.
