What factors could contribute to mastitis in a breastfeeding mother? (Select all that apply.)

Choice A rationale
Lying down with arms at the side is not the recommended position for a breast self-exam. The recommended positions are either standing or lying down with the arm raised.
Choice B rationale
Using the finger pads of the three middle fingers to apply pressure to the breast is a correct technique for a breast self-exam. This method allows for thorough examination of the breast tissue.
Choice C rationale
It is not correct to avoid checking under the arm if the breast feels fine. The breast tissue extends into the underarm area, so it is important to check this area as well during a breast self-exam.
Choice D rationale
Working from left to right down the breast towards the ribs is not a standard instruction for a breast self-exam. The recommended method is to use a circular, up-and-down, or wedge pattern.

Choice A rationale
Oral contraceptives are often used in the treatment of PCOS to restore menstrual regularity. They do this by regulating the hormonal imbalances that cause the irregular periods seen in PCOS678910.
Choice B rationale
While oral contraceptives can indirectly lead to ovulation in some women with PCOS by regulating their menstrual cycles, they are not typically used to directly induce ovulation. Other medications, such as clomiphene or letrozole, are more commonly used for this purpose.

Choice C rationale
While insulin resistance is a common feature of PCOS, oral contraceptives are not typically used to improve insulin uptake. Other medications, such as metformin, are more commonly used for this purpose.
Choice D rationale
While oral contraceptives can help alleviate hirsutism (excessive hair growth) in women with PCOS by reducing levels of circulating androgens, this is typically considered a secondary benefit rather than the primary rationale for their use.
