Post operative patient is to receive 55 MG of antibiotic per hour. The medication is available from the pharmacy as 500 MG of antibiotic per 1 L of IV bag. What should the IV pump be set to in mL\/min for the patient to receive the correct dosage?<\/p>\n\n\n\n

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

To determine the correct IV pump setting in mL\/min<\/strong>, follow these steps:<\/p>\n\n\n\n

Step 1: Identify Given Information<\/h3>\n\n\n\n
    \n
  • Dosage required<\/strong>: 55 mg per hour<\/li>\n\n\n\n
  • Available concentration<\/strong>: 500 mg per 1 L (1000 mL)<\/li>\n\n\n\n
  • Conversion factors<\/strong>: 1 L = 1000 mL, 1 hour = 60 minutes<\/li>\n<\/ul>\n\n\n\n

    Step 2: Find the Flow Rate in mL\/hour<\/h3>\n\n\n\n

    To determine how many mL of IV fluid contain 55 mg<\/strong> of the antibiotic:<\/p>\n\n\n\n

    [
    \\frac{1000 \\text{ mL}}{500 \\text{ mg}} = 2 \\text{ mL per mg}
    ]<\/p>\n\n\n\n

    Thus, for 55 mg<\/strong>:<\/p>\n\n\n\n

    [
    55 \\text{ mg} \\times 2 \\text{ mL\/mg} = 110 \\text{ mL per hour}
    ]<\/p>\n\n\n\n

    Step 3: Convert to mL\/min<\/h3>\n\n\n\n

    Since 1 hour = 60 minutes<\/strong>, divide by 60:<\/p>\n\n\n\n

    [
    \\frac{110 \\text{ mL}}{60 \\text{ min}} = 1.83 \\text{ mL\/min}
    ]<\/p>\n\n\n\n

    Final Answer: Set the IV pump to 1.83 mL\/min<\/strong><\/h3>\n\n\n\n
    \n\n\n\n

    Explanation (300 words)<\/h3>\n\n\n\n

    To ensure the patient receives the correct antibiotic dosage postoperatively, the IV pump must be accurately set based on the available concentration. The prescription requires 55 mg per hour<\/strong>, while the available IV solution contains 500 mg in 1000 mL<\/strong>, meaning each 1 mg is in 2 mL<\/strong> of solution.<\/p>\n\n\n\n

    By multiplying 55 mg by 2 mL\/mg<\/strong>, we determine the patient needs 110 mL of IV fluid per hour<\/strong>. However, IV pumps are set in mL per minute<\/strong>, requiring a conversion. Since 1 hour = 60 minutes<\/strong>, dividing 110 mL by 60<\/strong> gives 1.83 mL per minute<\/strong>.<\/p>\n\n\n\n

    This calculation is crucial because incorrect settings can lead to underdosing (ineffective treatment)<\/strong> or overdosing (toxicity risks)<\/strong>. In clinical practice, double-checking calculations and verifying IV pump settings are essential to ensure safe and effective medication administration<\/strong>.<\/p>\n\n\n\n

    Thus, the IV pump should be set to 1.83 mL\/min<\/strong> to deliver the prescribed antibiotic dosage correctly.<\/p>\n","protected":false},"excerpt":{"rendered":"
