'Case Study, Chapter 13, Fluld and Electrolytes: Balance and Disturbance Mrs: Dean is 75-year-old woman admitted to the hospital for a small bowel obstruction: Her medical history includes hypertension: Mrs. Dean is NPO. She has a nasogastric (NG) tube to low continuous suction She has an IV of 0.9% NS at 83 mLhr: Current medications include furosemide 20 mg daily and hydromorphone 0.2 mg every 4 hours, needed for pain. The morning electrolytes reveal serum potassium of 3.2 mEq/L (Learning Objective 4) What are possible causes of a low potassium level? What action should the nurse take in relation to the serum potassium level? What clinical manifestations might the nurse assess in Mrs. Dean?'

Step 1
Dean has a low serum potassium level of 3.2 mEq/L. Normal serum potassium levels typically range from 3.5 to 5.0 mEq/L. Therefore, she is experiencing hypokalemia. Show more…
