📚 Polycystic Ovary Syndrome — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Polycystic ovary syndrome is a common endocrine disorder of reproductive-age women marked by hyperandrogenism, irregular ovulation, and often polycystic ovaries on ultrasound. Insulin resistance is central, linking PCOS to type 2 diabetes and metabolic syndrome. It is a leading cause of infertility.
🔑
Key points
Understand these first
Classic triad: irregular or absent menses (anovulation), signs of excess androgens (hirsutism, acne, male-pattern hair thinning), and polycystic ovaries on ultrasound.
Insulin resistance is a core feature, increasing risk for type 2 diabetes, obesity, dyslipidemia, and metabolic syndrome.
PCOS is a common cause of infertility due to lack of ovulation.
Chronic anovulation causes unopposed estrogen, raising the risk of endometrial hyperplasia and cancer.
First-line management includes weight loss and lifestyle change; metformin improves insulin sensitivity and ovulation.
Combined oral contraceptives regulate cycles and reduce androgen symptoms; clomiphene or letrozole induce ovulation for those seeking pregnancy.
✅
Nursing priorities
What to do, in order
Screen for insulin resistance and diabetes with fasting glucose, A1C, or oral glucose tolerance testing.
Promote weight loss and exercise, which can restore ovulation and improve metabolic markers.
Educate on prescribed oral contraceptives, metformin, or ovulation-induction agents and their purpose.
Provide emotional support addressing body image, fertility concerns, and risk of depression/anxiety.
Monitor blood pressure and lipid profile for cardiovascular risk.
🚩
Red flags — report now
Escalate immediately
Prolonged or heavy abnormal uterine bleeding — may signal endometrial hyperplasia requiring evaluation.
Even a 5-10% weight loss can restore regular ovulation and reduce diabetes risk.
Regular menstrual cycles protect the uterine lining; report cycles fewer than 8-9 per year.
PCOS raises lifelong risk for diabetes and heart disease, so ongoing screening is important.
Take metformin with meals to reduce GI upset and report persistent nausea or diarrhea.
❓ Polycystic Ovary Syndrome: NCLEX FAQs
What are the priority nursing interventions for Polycystic Ovary Syndrome?
Screen for insulin resistance and diabetes with fasting glucose, A1C, or oral glucose tolerance testing. Promote weight loss and exercise, which can restore ovulation and improve metabolic markers. Educate on prescribed oral contraceptives, metformin, or ovulation-induction agents and their purpose. Provide emotional support addressing body image, fertility concerns, and risk of depression/anxiety.
What are the warning signs of Polycystic Ovary Syndrome a nurse must report?
Prolonged or heavy abnormal uterine bleeding — may signal endometrial hyperplasia requiring evaluation. Signs of metformin-associated lactic acidosis (rare): muscle pain, fatigue, difficulty breathing — report immediately.
