A nurse in a provider's office is planning care for a client who has a new diagnosis of polycystic ovarian syndrome. The nurse should plan to monitor which of the following laboratory values?

A. Thyroid-stimulating hormone (TSH) → Thyroid disorders can cause menstrual irregularities but are not directly linked to PCOS. B. Glucose → Insulin resistance is a hallmark of PCOS, making glucose monitoring essential for detecting diabetes risk. C. BUN (Blood Urea Nitrogen) → PCOS does not primarily affect kidney function. D. Liver function tests → While metabolic syndrome in PCOS can contribute to fatty liver, routine liver function tests are not a first-line concern.
