During cardiac arrest, if an I.V. route is unavailable, epinephrine can be administered endotracheally. Pernicious anemia results from the failure to absorb vitamin B12 in the GI tract and causes primarily GI and neurologic signs and symptoms. A patient who has a pressure ulcer should consume a high-protein, high-calorie diet, unless contraindicated. The CK-MB isoenzyme level is used to assess tissue damage in myocardial infarction. After a 12-hour fast, the normal fasting blood glucose level is 80 to 120 mg/dl. A patient who is experiencing digoxin toxicity may report nausea, vomiting, diplopia, blurred vision, light flashes, and yellow-green halos around images. Anuria is daily urine output of less than 100 ml. In remittent fever, the body temperature varies over a 24-hour period, but remains elevated. Risk of a fat embolism is greatest in the first 48 hours after the fracture of a long bone. It’s manifested by respiratory distress.
