Treatment for Hemochromatosis
Routine phlebotomy
Priority assessment in patient with stroke related impaired function of the mouth, tongue, palate, larynx, pharynx, or upper esophagus.
Swallow assessment
Used to restore a fast and unstable heart rate through timed, synchronized shock delivery
Cardioversion
Clinical manifestations include: cough, shortness of breath, oliguria, frothy-pink tinged sputum, crackles in lungs; S3 (third heart sound) or ventricular gallop
