Introduction
NP scope You order and interpret thyroid tests in ambulatory care, initiate/adjust levothyroxine for overt hypothyroidism when appropriate, refer hyperthyroidism and nodules with concerning features, and coordinate with OB/endocrine for pregnancy and storm risk. WHNP items may foreground preconception and trimester targets; PNP-PC may include congenital hypothyroidism follow-up themes at a principles level when hinted. Expect next test (antibodies, imaging referral), therapy start/titration, subclinical watch vs treat, beta-blocker for symptomatic hyperthyroidism while awaiting specialty care, and storm vs anxiety differentiation. Traps • Treating abnormal TSH in acute illness without clinical correlation. • Ignoring pregnancy trimester rules. • Missing compressive or malignant nodule features.
