A nurse is preparing to administer ampicillin to a school-age child who weighs 55 lb. The provider prescribes 50 mg\/kg\/day in 4 equal doses. Available is ampicillin oral suspension 125 mg\/5 mL. How many ml should the nurse administer with each dose?<\/p>\n\n\n\n
The correct answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n To calculate how many mL the nurse should administer for each dose, we need to follow a step-by-step approach:<\/p>\n\n\n\n Since the weight is given in pounds (lb), we first convert it to kilograms (kg).<\/p>\n\n\n\n [ 1 \\text{ lb} = 0.453592 \\text{ kg} ]<\/p>\n\n\n\n [ 55 \\text{ lb} \\times 0.453592 = 24.94 \\text{ kg} ]<\/p>\n\n\n\n The provider prescribes 50 mg\/kg\/day. Now, we calculate the total daily dose by multiplying the weight in kilograms by the prescribed dose.<\/p>\n\n\n\n [ 50 \\text{ mg\/kg\/day} \\times 24.94 \\text{ kg} = 1,247 \\text{ mg\/day} ]<\/p>\n\n\n\n The medication needs to be administered in 4 equal doses throughout the day. To get the amount of medication for each dose:<\/p>\n\n\n\n [ \\frac{1,247 \\text{ mg}}{4} = 311.75 \\text{ mg\/dose} ]<\/p>\n\n\n\n The available concentration of ampicillin is 125 mg per 5 mL. To find out how many mL corresponds to 311.75 mg:<\/p>\n\n\n\n Use the ratio of the available medication:<\/p>\n\n\n\n [ \\frac{125 \\text{ mg}}{5 \\text{ mL}} = \\frac{311.75 \\text{ mg}}{X \\text{ mL}} ]<\/p>\n\n\n\n Solving for ( X ):<\/p>\n\n\n\n [ X = \\frac{311.75 \\times 5}{125} = 12.47 \\text{ mL} ]<\/p>\n\n\n\n The nurse should administer 12.47 mL<\/strong> of the ampicillin suspension with each dose.<\/p>\n\n\n\n In this situation, precise calculation is critical to ensure the child receives the correct amount of medication, preventing both underdosing and overdosing. The process involves unit conversion, understanding the prescribed dose, and calculating the right volume based on the available drug concentration. The key is to break the calculation into manageable steps: converting weight, determining the total daily dose, dividing by the number of doses, and then using proportional relationships to convert milligrams into milliliters based on the drug’s suspension strength.<\/p>\n","protected":false},"excerpt":{"rendered":" A nurse is preparing to administer ampicillin to a school-age child who weighs 55 lb.
