Why to assess cardiovascular status? | this affects the excretion of drugs and waste products, including analgesic and anesthetic products. If this is reduced, electrolytes can be altered |

What risk does hypokalemia present to surgical patients? | it increases the risks for toxicity if the patient is taking dig, slows the recovery from anesthesia, and increases cardiac irritability |
What risk does hyperkalemia present to surgical patients? | it increases the risk for dysrhythmias, especially with use of anesthesia |
