I'm working on my nursing process paper, and I'm trying to figure out which diagnosis would be more of a priority:
excess fluid volume r/t CHF AEB dyspnea, bilateral lower extremity edema, potassium level of 3.3 MEq (low), pleural effusion
ineffective cardiopulmonary tissue perfusion r/t decreased hemoglobin concentration in blood AEB dyspnea, BLE edema, decreased urination, RBC count of 3.37, HGB count of 10.3, fatigue, respiratory alkalosis
I'm not sure if impaired tissue perfusion is caused by the excess fluid volume, or if the excess fluid volume is caused by the ineffective tissue perfusion. Can someone please explain it to me? and which one you would use as a priority diagnosis in a CHF patient who is in the hospital for SOB and severe BLE edema?
