مريض كبير في العمر عنده مرض قلب، شُخص بقصور الغدة الدرقية. كيف يُبدأ الليفوثيروكسين عادة؟

An older client with heart disease is diagnosed with hypothyroidism. How is levothyroxine usually started?

1. Every other day to reduce side effects
2. At full dose from day one for rapid correction
3. At a low dose increased slowly while watching for angina
4. At a high IV dose for one week

Answer: C) At a low dose increased slowly while watching for angina. In older and cardiac clients a low starting dose is used because a rapid rise in metabolism may cause angina or arrhythmia.
