What is the full replacement dose of Levothyroxine for an adult?

1.6 mcg/kg/day
1.2 mcg/kg/day
2 mcg/kg/day
0.8 mcg/kg/day

The correct answer is: 1.6 mcg/kg/day

The full replacement dose of Levothyroxine for an adult is 1.6 mcg/kg/day. This is the recommended dosage to be taken orally, once daily, for those with hypothyroidism. Options B, C, and D are not the full replacement dose and may result in under- or over-replacement of thyroid hormone. Option B is lower than the recommended dose and may not adequately treat hypothyroidism, while options C and D are higher and may lead to hyperthyroidism and potentially harmful side effects. It is important to follow the recommended dosage of 1.6 mcg/kg/day for optimal treatment of hypothyroidism.
