When educating a teenager about ovulation, the nurse would include that ovulation is triggered by a surge in which hormone?
Estrogen.
Progesterone.
Luteinizing Hormone (LH).
Prostaglandins.
The Correct Answer is C
Choice A rationale
Estrogen is a hormone that plays a crucial role in the menstrual cycle and pregnancy. However, it is not the primary hormone that triggers ovulation.
Choice B rationale
Progesterone is a hormone that prepares the uterus for pregnancy after ovulation. It does not trigger ovulation.
Choice C rationale
Luteinizing Hormone (LH) is the hormone that triggers ovulation. A surge in LH levels causes the mature follicle in the ovary to burst and release an egg.
Choice D rationale
Prostaglandins are hormone-like substances involved in pain and inflammation. They do not trigger ovulation.
