Prove mathematically the ordered dose by the physician (mg\/kg\/dose) and is it safe to give.<\/p>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-6-color\">The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n<p>To determine if the physician&#8217;s ordered dose of morphine for the infant is within the recommended range, we need to calculate the infant&#8217;s weight in kilograms and the dosage in milligrams per kilogram (mg\/kg).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Convert the infant\u2019s weight from pounds and ounces to kilograms.<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1 pound = 16 ounces, so 6 pounds 3 ounces = 6 + (3\/16) pounds.<\/li>\n\n\n\n<li>3 ounces is 3\/16 of a pound: 3\u00a0ounces=0.1875\u00a0pounds3 \\text{ ounces} = 0.1875 \\text{ pounds}3\u00a0ounces=0.1875\u00a0pounds Therefore: 6\u00a0pounds3\u00a0ounces=6.1875\u00a0pounds6 \\text{ pounds} 3 \\text{ ounces} = 6.1875 \\text{ pounds}6\u00a0pounds3\u00a0ounces=6.1875\u00a0pounds<\/li>\n\n\n\n<li>Convert pounds to kilograms by multiplying by 0.4536 (since 1 pound = 0.4536 kg): 6.1875\u00a0pounds\u00d70.4536=2.806\u00a0kg6.1875 \\text{ pounds} \\times 0.4536 = 2.806 \\text{ kg}6.1875\u00a0pounds\u00d70.4536=2.806\u00a0kg<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Calculate the recommended dose range.<\/h3>\n\n\n\n<p>The recommended dosage is 0.1-0.2 mg\/kg per dose.<\/p>\n\n\n\n<p>For a weight of 2.806 kg, the dose range is calculated as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Lower limit<\/strong>: 0.1\u00a0mg\/kg\u00d72.806\u00a0kg=0.2806\u00a0mg0.1 \\text{ mg\/kg} \\times 2.806 \\text{ kg} = 0.2806 \\text{ mg}0.1\u00a0mg\/kg\u00d72.806\u00a0kg=0.2806\u00a0mg<\/li>\n\n\n\n<li><strong>Upper limit<\/strong>: 0.2\u00a0mg\/kg\u00d72.806\u00a0kg=0.5612\u00a0mg0.2 \\text{ mg\/kg} \\times 2.806 \\text{ kg} = 0.5612 \\text{ mg}0.2\u00a0mg\/kg\u00d72.806\u00a0kg=0.5612\u00a0mg<\/li>\n<\/ul>\n\n\n\n<p>Thus, the safe dosage range for this infant is <strong>0.2806 mg to 0.5612 mg<\/strong> per dose.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Compare the physician&#8217;s order to the recommended range.<\/h3>\n\n\n\n<p>The physician has ordered 0.5 mg of morphine per dose. This dose falls within the recommended range of 0.2806 mg to 0.5612 mg.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Conclusion<\/h3>\n\n\n\n<p>Since the ordered dose of 0.5 mg is within the safe range of 0.2806 mg to 0.5612 mg, it is safe to administer this dose to the infant.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>Calculating medication dosages for infants requires attention to both weight and recommended dosing guidelines. Morphine is prescribed for pain relief in post-operative cases, and its dose must be tailored to avoid underdosing, which may lead to insufficient pain relief, or overdosing, which could cause dangerous side effects like respiratory depression.<\/p>\n\n\n\n<p>The conversion of the infant&#8217;s weight to kilograms ensures accuracy in applying the recommended dose range, as medication dosages are typically based on body weight in metric units (mg\/kg). The calculation confirms that 0.5 mg of morphine is within the recommended range for an infant of this weight, meaning it is both appropriate and safe to administer this amount.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>An infant weighing 6 pounds 3 ounces has morphine 0.5 mg IV q 2 hours prn ordered for post op pain.
