The daily dose of antibiotic for the treatment of an ear infection is 115 mg\/kg of body weight. If the antibiotic tablets are available in 250 mg size, calculate the number of tablets that a 33.5 lb. child must take per day<\/p>\n\n\n\n
The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n To solve this problem, we need to follow several steps involving unit conversion<\/strong>, dosage calculation<\/strong>, and tablet counting<\/strong>.<\/p>\n\n\n\n We are given:<\/p>\n\n\n\n [ The prescription is:<\/p>\n\n\n\n [ Available tablet strength = 250 mg\/tablet<\/strong><\/p>\n\n\n\n [ So, the child needs to take approximately 7 tablets per day<\/strong>.<\/p>\n\n\n\n Since partial tablets may not be recommended depending on the formulation (especially for coated or extended-release tablets), a clinician or pharmacist<\/strong> would need to confirm the exact dosing method. However, for this problem:<\/p>\n\n\n\n This problem involves a typical pediatric medication calculation that requires careful conversion and application of dosage principles. The dosage for many medications is based on body weight, especially in children, to ensure safety and efficacy. Here, the child weighs 33.5 pounds, which needs to be converted into kilograms because medical dosing is typically done using the metric system (milligrams per kilogram). Dividing 33.5 lb by 2.2 gives us approximately 15.23 kg.<\/p>\n\n\n\n Next, the total dose is calculated using the prescribed dosage of 115 mg per kg. Multiplying 115 mg\/kg by 15.23 kg results in approximately 1751.45 mg per day. This is the total amount of antibiotic the child needs to receive each day.<\/p>\n\n\n\n The final step is to determine how many tablets this equates to, given that each tablet contains 250 mg of the antibiotic. Dividing 1751.45 mg by 250 mg\/tablet gives us approximately 7.01 tablets. Since tablets usually come in fixed sizes, and it may not be safe or practical to split them (especially if they are not scored or are extended-release), most clinicians would round to the nearest whole number\u2014in this case, 7 tablets per day<\/strong>.<\/p>\n\n\n\n This calculation emphasizes the importance of accuracy in pediatric dosing, as underdosing may lead to ineffective treatment and overdosing can cause toxicity. Always confirm with a healthcare provider before adjusting doses based on weight.<\/p>\n\n\n\n The daily dose of antibiotic for the treatment of an ear infection is 115 mg\/kg of body weight.
