Problem: Ms. Hackworth is tired all the time. The nurse practitioner orders a thyroid-stimulating hormone level drawn. The result is higher than normal. 1) You make the call to have Ms. Hackworth come in to the clinic for further evaluation. She asks, If my thyroid level is high, then why am I so tired? How should you respond? 2) After further testing, the nurse practitioner places Ms. Hackworth on levothyroxine (Synthroid) 50 mcg daily. Her pharmacist supplies Synthroid 0.05 mg. Is her dose correct?
