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?

Choice A rationale Thyroid-stimulating hormone (TSH) levels are monitored to assess thyroid function. While there can be some endocrine interplay, TSH is not a primary lab value directly associated with the diagnostic or management criteria for polycystic ovarian syndrome (PCOS). PCOS primarily involves ovarian dysfunction and insulin resistance. Normal range for TSH is typically 0.4-4.0 mIU/L. Choice B rationale Liver function tests (LFTs) assess the health and function of the liver. While some individuals with PCOS may develop non-alcoholic fatty liver disease (NAFLD) due to metabolic dysfunction, LFTs are not a primary diagnostic or routine monitoring parameter for all PCOS clients unless specific symptoms or risk factors are present. Normal range for ALT is typically 7-55 U/L, and AST is 8-48 U/L. Choice C rationale Blood urea nitrogen (BUN) is a marker of kidney function. PCOS primarily affects the endocrine and reproductive systems, and BUN is not directly involved in its diagnosis or routine management. Kidney function is not inherently compromised by PCOS itself. Normal range for BUN is typically 6-20 mg/dL. Choice D rationale Blood glucose monitoring is crucial for clients with polycystic ovarian syndrome due to the strong association with insulin resistance. Insulin resistance is a hallmark of PCOS and increases the risk of developing impaired glucose tolerance, type 2 diabetes mellitus, and metabolic syndrome. Therefore, assessing blood glucose levels, including fasting glucose or glucose tolerance tests, is essential for early detection and management of these metabolic complications. Normal fasting blood glucose is typically 70-99 mg/dL.
