A client who is admitted with emphysema is having difficulty breathing. In which positionshould the nurse place the client? A.High Fowler's position without a pillow behind the head B.Semi-Fowler's position with a single pillow behind the head C.Right side-lying position with the head of the bed elevated 45 degrees D.Sitting upright and forward with both arms supported on an over the bed tableD Adequate lung expansion is dependent on deep breaths that allow the respiratory muscles to increase the longitudinal and anterior-posterior size of the thoracic cage. Sitting upright and leaning forward with the arms supported on an over the bed table (D)allows the thoracic cage to expand in all four directions and reduces dyspnea. A high Fowler's position does not allow maximum expansion of the posterior lobes of the lungs(A). A semiFowler's position restricts expansion of the anterior-posterior diameter of the thoracic cage (B). Positioning a client on the right side with the head of the bed elevated (C) does not facilitate lung expansion. A client with chronic renal insufficiency (CRI) is taking 25 mg of hydrochlorothiazide (HCTZ) PO and 40 mg of furosemide (Lasix) PO daily. Today, at a routine clinic visit, theclient's serum potassium level is 4 mEq/L. What is the most likely cause of this client's potassium level?
