Describe the menstrual phase
What will be an ideal response?
The menstrual phase is the most overt phase, characterized by discharge of blood and endometrial debris from the vagina. By convention, the first day of menstruation is considered the start of a new cycle. It coincides with the end of the ovarian luteal phase and onset of a new follicular phase. As the corpus luteum degenerates because fertilization and implantation of the ovum released during the preceding cycle did not take place, circulating levels of progesterone and estrogen drop precipitously. Because the net effect of progesterone and estrogen is to prepare the endometrium for implantation of a fertilized ovum, withdrawal of these steroids deprives the highly vascular, nutrient-rich uterine lining of its hormonal support.

What will be an ideal response?
Following a traumatic injury, a 19-year-old woman presents with confusion, tachycardia, and significant hypotension. Her skin is cool, clammy, and pale. Further assessment reveals abdominal rigidity and deformity with severe pain over her thoracic vertebrae. In addition to administering high-flow oxygen and immobilizing her spine, you should:
A) start at least one large-bore IV line and give crystalloid boluses as needed to maintain adequate perfusion. B) conclude that she is in neurogenic shock, start an IV line of normal saline, and initiate a dopamine infusion. C) start at least one large-bore IV of normal saline and administer a narcotic analgesic to treat her severe pain. D) perform a focused history and physical exam, start an IV of normal saline, and administer a corticosteroid.
