A nurse is preparing to administer 40 mEq of potassium chloride in 45% sodium chloride (NaCl) 500 mL IV to infuse 10 mEq\/hr. The nurse should set the IV pump to deliver how many mL\/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)<\/p>\n\n\n\n

The correct answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

To determine how many mL\/hr the IV pump should be set to deliver, follow these steps:<\/p>\n\n\n\n

    \n
  1. Understand the infusion rate:<\/strong>
    The nurse needs to administer 40 mEq of potassium chloride (KCl) at a rate of 10 mEq\/hr. This means the total infusion rate for the potassium chloride solution must be set to deliver 10 mEq of KCl per hour.<\/li>\n\n\n\n
  2. Calculate the total volume of the IV solution:<\/strong>
    The potassium chloride is diluted in 500 mL of 45% sodium chloride (NaCl) solution. The concentration of potassium chloride in this solution needs to be determined in mEq\/mL.<\/li>\n\n\n\n
  3. Determine the concentration of KCl in the solution:<\/strong><\/li>\n<\/ol>\n\n\n\n
      \n
    • The total amount of potassium chloride in the solution is 40 mEq.<\/li>\n\n\n\n
    • The total volume of the solution is 500 mL. Therefore, the concentration of KCl in the solution is:
      [
      \\text{Concentration} = \\frac{\\text{Total KCl (mEq)}}{\\text{Total Volume (mL)}} = \\frac{40 \\text{ mEq}}{500 \\text{ mL}} = 0.08 \\text{ mEq\/mL}
      ]<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Calculate the infusion rate in mL\/hr:<\/strong>
        To deliver KCl at a rate of 10 mEq\/hr, use the concentration to find the necessary infusion rate in mL\/hr:
        [
        \\text{Infusion Rate (mL\/hr)} = \\frac{\\text{Desired Rate (mEq\/hr)}}{\\text{Concentration (mEq\/mL)}} = \\frac{10 \\text{ mEq\/hr}}{0.08 \\text{ mEq\/mL}} = 125 \\text{ mL\/hr}
        ]<\/li>\n<\/ol>\n\n\n\n

        Thus, the IV pump should be set to deliver 125 mL\/hr<\/strong>.<\/p>\n\n\n\n

        Explanation:<\/strong><\/p>\n\n\n\n

        In this scenario, you need to calculate the infusion rate based on the concentration of potassium chloride in the solution. By dividing the required infusion rate of potassium chloride (10 mEq\/hr) by its concentration in the solution (0.08 mEq\/mL), you determine how fast the IV pump should deliver the solution to achieve the correct dose per hour. The result, 125 mL\/hr, ensures that the patient receives the prescribed amount of potassium chloride at the desired rate.<\/p>\n","protected":false},"excerpt":{"rendered":"
