A nurse is providing education to a client who has recently undergone pelvic floor surgery. The client asks about the voluntary control of urination. Which anatomical structure allows for conscious control over the initiation of urine flow?

A. Protects against heart disease: Estrogen has several effects on the cardiovascular system (improving lipid profile and vascular function) that are thought to reduce cardiovascular risk prior to menopause.
B. Helps regulate the menstrual cycle: Estrogen is a key ovarian hormone that helps regulate the growth of the endometrium and the timing of the menstrual cycle .
C. Promotes bone growth: Estrogen is essential for bone homeostasis, inhibiting bone resorption and helping maintain bone density .
D. Increases testosterone production: Estrogen does not increase testosterone production; testosterone is produced by Leydig cells in males (and ovaries/adrenals in females) and is not a primary product increased by estrogen .

A. Urea: Urea is a normal nitrogenous waste product excreted in urine; its presence alone is not indicative of diabetes (it reflects protein metabolism/kidney function).
B. Creatinine: Creatinine is a normal urinary waste product used to assess kidney function; its presence alone is not diagnostic of diabetes.
C. Glucose: Glucosuria (significant glucose in urine) suggests hyperglycemia and impaired glucose handling (common in diabetes) -indicative of a diabetic problem if present in large amounts.
D. Ketones: Ketonuria (significant ketones in urine) indicates fat breakdown/ketosis and is a sign of uncontrolled diabetes (e.g., diabetic ketoacidosis) -indicative of diabetic metabolic disturbance.
