Therefore, hypokalemia • What is the nursing intervention? o Pt need suctioning because of seizures If pH goes below 7.35, this is acidosis • Therefore, everything is down: bradycardia, constipation, absent bowel sounds, flaccid, obtunded, lethargy, coma hyporeflexia (0, 1+), bradypnea, low BP • However, potassium is high (hyperkalemia) • What is the nursing intervention? o Pt needs to be ventilated with an Ambu bag—respiratory arrest So, remember that “MAC Kussmaul” is the only acid-base imbalance to cause Metabolic ACidosis with Kussmaul respirations
