The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n To determine the correct dosage of levothyroxine for the patient, we use the following formula:<\/p>\n\n\n\n Dosage (mcg) = Dosage per kilogram \u00d7 Weight (kg)<\/strong><\/p>\n\n\n\n 0.8\u2009\u03bcg\/kg\u00d792\u2009kg=73.6\u2009\u03bcg per dose0.8 \\, \\mu g\/kg \\times 92 \\, kg = 73.6 \\, \\mu g \\text{ per dose}<\/p>\n\n\n\n Since the medication is administered every 12 hours<\/strong>, that means the patient will receive 2 doses per day<\/strong>.<\/p>\n\n\n\n So, total daily dose: 73.6\u2009\u03bcg\u00d72=147.2\u2009\u03bcg\/day73.6 \\, \\mu g \\times 2 = 147.2 \\, \\mu g\/day<\/p>\n\n\n\n C) 147.2 mcg<\/strong><\/p>\n\n\n\n Levothyroxine is a synthetic form of the thyroid hormone T4<\/strong>, and it is commonly prescribed for patients with hypothyroidism or after thyroidectomy. Dosing is carefully calculated based on body weight (in micrograms per kilogram)<\/strong> to ensure appropriate replacement of thyroid hormone.<\/p>\n\n\n\n In this case, the patient\u2019s weight is 92 kg<\/strong>, and the prescribed dose is 0.8 mcg\/kg every 12 hours<\/strong>. First, calculate the single dose:<\/p>\n\n\n\n Since the medication is to be administered twice daily (q12h)<\/strong>, the total daily dose<\/strong> becomes:<\/p>\n\n\n\n This approach ensures accurate dosing based on weight and frequency. Dosing errors can lead to either undertreatment<\/strong> (resulting in persistent hypothyroid symptoms such as fatigue, weight gain, and bradycardia) or overtreatment<\/strong> (leading to symptoms of hyperthyroidism such as palpitations, weight loss, and anxiety).<\/p>\n\n\n\n Therefore, understanding weight-based dosage calculations and frequency adjustments is critical for safe medication administration in clinical nursing practice.<\/p>\n\n\n\n \u2705 C) 147.2 mcg<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" Patient is prescribed 0.8 micrograms of levothyroxine per kilogram q 12 hours.
