An infant who weighs 22 pounds receives a prescription for amoxicillin 20 mg\/kg\/day by mouth in divided doses every 8 hours. The bottle is labeled, “Amoxicillin for Oral Suspension, USP 250 mg per 5 mL.” How many mL should the nurse administer with each dose? (Enter numerical value only. If rounding is necessary, round to the nearest tenth.)<\/p>\n\n\n\n
The correct answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n To determine the correct dosage of amoxicillin for the infant, follow these steps:<\/p>\n\n\n\n The infant weighs 22 pounds. First, convert this weight into kilograms. The conversion factor is 1 pound = 0.453592 kilograms.<\/p>\n\n\n\n [ 22 \\text{ pounds} \\times 0.453592 \\text{ kg\/pound} = 9.979 \\text{ kg} ]<\/p>\n\n\n\n Rounding to one decimal place, the weight is approximately 10 kg.<\/p>\n\n\n\n The prescription is for 20 mg of amoxicillin per kilogram of body weight per day. To find the total daily dose for the infant:<\/p>\n\n\n\n [ 20 \\text{ mg\/kg\/day} \\times 10 \\text{ kg} = 200 \\text{ mg\/day} ]<\/p>\n\n\n\n The medication is to be administered in divided doses every 8 hours. There are 24 hours in a day, so the number of doses per day is:<\/p>\n\n\n\n [ \\frac{24 \\text{ hours\/day}}{8 \\text{ hours\/dose}} = 3 \\text{ doses\/day} ]<\/p>\n\n\n\n Thus, the amount of amoxicillin per dose is:<\/p>\n\n\n\n [ \\frac{200 \\text{ mg\/day}}{3 \\text{ doses\/day}} = 66.67 \\text{ mg\/dose} ]<\/p>\n\n\n\n The concentration of the amoxicillin suspension is 250 mg per 5 mL. To find out how many mL are needed to administer 66.67 mg:<\/p>\n\n\n\n First, determine the amount of mg per mL:<\/p>\n\n\n\n [ \\frac{250 \\text{ mg}}{5 \\text{ mL}} = 50 \\text{ mg\/mL} ]<\/p>\n\n\n\n Now, calculate the volume needed for 66.67 mg:<\/p>\n\n\n\n [ \\frac{66.67 \\text{ mg}}{50 \\text{ mg\/mL}} = 1.333 \\text{ mL} ]<\/p>\n\n\n\n Rounding 1.333 mL to the nearest tenth gives:<\/p>\n\n\n\n [ 1.3 \\text{ mL} ]<\/p>\n\n\n\n Therefore, the nurse should administer 1.3 mL of the amoxicillin suspension with each dose.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" An infant who weighs 22 pounds receives a prescription for amoxicillin 20 mg\/kg\/day by mouth in divided doses every 8 hours.
