网考网试题解析：
Increasing fluid volume and urine output is the main consideration when fluid replacement therapy is indicated. Therefore, DSW and a hypotonic solution would be indicated. Distilled water is never given for IV replacement therapy, even though it’s a hypotonic solution. Potassium chloride is added when adequate output is established, depending on the extent of hypokalemia determined by laboratory electrolyte studies. Dextrose 10% in saline is a hypertonic solution that increases the degree of osmotic pressure and would increase intracellular dehydration; therefore, it’s contraindicated. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
