Which antidiabetic medication is a sulfonylurea?

Choice A rationale: this is the correct answer since the darkened spots in the uterus represent endometrial-like tissue growths within the muscular wall of the uterus (the myometrium).

Choice B rationale: This picture shows leiomyomas, also known as fibroids, which are benign tumors that develop from the smooth muscle cells of the uterus. They can vary in size, number, and location within or outside the uterus. They can cause symptoms such as heavy bleeding, pelvic pressure, pain, and infertility.

Choice C rationale: This is endometriosis which is a condition where tissue similar to the endometrium (the lining of the uterus) grows outside the uterus, such as on the ovaries, fallopian tubes, pelvic wall, or bowel. This tissue responds to hormonal changes and bleeds during the menstrual cycle, causing inflammation, pain, and sometimes infertility.

Choice D rationale: This image shows a normal uterus.

Choice A rationale: This is a sign of worsening diabetes insipidus.

Choice B rationale: This shows signs of overhydration, as urine output is high and specific gravity is high.

Choice C rationale: This is a sign of worsening diabetes insipidus.

Choice D rationale: Vasopressin is a hormone that helps the kidneys retain water and concentrate urine. Diabetes insipidus is a condition where the body does not produce enough vasopressin or does not respond to it, resulting in excessive urination and diluted urine. The goal of vasopressin therapy is to reduce urine output and increase urine concentration, which indicates that the kidneys are functioning properly and the body is hydrated.
