Answer :
a) 88 mcg
For an adult patient with hypothyroidism, the typical starting dose of Levothyroxine is about 1.6 mcg/kg of body weight per day. For a 150 lb (approximately 68 kg) patient, this would be around 109 mcg. However, in clinical practice, it is common to start with a lower dose, especially if the patient has no other comorbidities and to avoid potential side effects. Therefore, 88 mcg is a reasonable starting dose, with the plan to adjust based on follow-up thyroid function tests.
