The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

To determine how many grams of dextrose are contained in a 500 mL IV solution of D5W (dextrose 5% in water), we need to understand the composition of the solution. The “5%” in D5W indicates that the solution contains 5% dextrose by weight\/volume.<\/p>\n\n\n\n

Here\u2019s a step-by-step explanation of how to calculate the grams of dextrose:<\/p>\n\n\n\n

    \n
  1. Understand the Concentration<\/strong>: The term “5% dextrose in water” means that 5% of the weight of the solution is dextrose. This percentage is based on the weight\/volume (w\/v) ratio, which in this case means 5 grams of dextrose per 100 mL of solution.<\/li>\n\n\n\n
  2. Convert the Volume<\/strong>: Since the volume of the IV solution is 500 mL, we can use the percentage concentration to find out how many grams of dextrose are in this volume.<\/li>\n\n\n\n
  3. Calculate the Amount of Dextrose<\/strong>:\n
      \n
    • First, determine how many grams of dextrose are in 100 mL of the solution: 5 grams.<\/li>\n\n\n\n
    • To find out how many grams are in 500 mL, use a proportion. Since 100 mL contains 5 grams, 500 mL will contain: Amount\u00a0of\u00a0dextrose=5\u00a0grams100\u00a0mL\u00d7500\u00a0mL\\text{Amount of dextrose} = \\frac{5 \\text{ grams}}{100 \\text{ mL}} \\times 500 \\text{ mL}Amount\u00a0of\u00a0dextrose=100\u00a0mL5\u00a0grams\u200b\u00d7500\u00a0mL<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Perform the Calculation<\/strong>:Amount\u00a0of\u00a0dextrose=5\u00a0grams\u00d7500\u00a0mL100\u00a0mL=25\u00a0grams\\text{Amount of dextrose} = \\frac{5 \\text{ grams} \\times 500 \\text{ mL}}{100 \\text{ mL}} = 25 \\text{ grams}Amount\u00a0of\u00a0dextrose=100\u00a0mL5\u00a0grams\u00d7500\u00a0mL\u200b=25\u00a0grams<\/li>\n<\/ol>\n\n\n\n

      So, in a 500 mL IV solution of D5W, there are 25 grams of dextrose.<\/p>\n\n\n\n

      Correct Answer: B. 25 g<\/strong><\/p>\n\n\n\n

      This calculation is essential for ensuring proper dosing and understanding the nutritional and caloric intake provided by intravenous fluids. Accurate measurements are crucial for patient safety and effective treatment.<\/p>\n","protected":false},"excerpt":{"rendered":"
