A woman at low risk and with no family history of breast cancer comes to the clinic and asks the nurse about when she should have her first mammogram.
According to the recommendations of the American Cancer Society, at what age should the woman have her first mammogram?

Choice A rationale
Theca-lutein cysts are not commonly found in females of reproductive age. They are often associated with conditions that cause high levels of human chorionic gonadotropin, such as molar pregnancies.
Choice B rationale
Corpus luteum cysts can occur in women of reproductive age, but they do not typically regress with the menstrual cycle. Instead, they usually resolve after a few weeks if pregnancy does not occur.
Choice C rationale
Follicular cysts are commonly found in females of reproductive age and often regress with the menstrual cycle. They form when the follicle that normally releases an egg does not open to release the egg.

Choice D rationale
Polycystic ovarian syndrome is a condition characterized by multiple small cysts in the ovaries, but it does not typically cause cysts that regress with the menstrual cycle.

Choice A rationale
Hypothermia is not a typical response to phototherapy in an isolette. The heat from the phototherapy lights would typically prevent hypothermia.
Choice B rationale
Bradycardia, or a slow heart rate, is not a typical response to phototherapy in an isolette. If bradycardia occurs, it could be a sign of a serious condition that needs immediate medical attention.
Choice C rationale
Dehydration is a possible response to phototherapy in an isolette. The lights used in phototherapy can cause an infant to lose more water through their skin, leading to dehydration.
Choice D rationale
Decreased muscle tone is not a typical response to phototherapy in an isolette. If decreased muscle tone is observed, it could be a sign of a serious condition that needs immediate medical attention.
