A nurse is teaching a new mother about breastfeeding. The nurse determines that the teaching was successful when the woman identifies which hormone as responsible for milk let-down?

progesterone

estrogen

prolactin

oxytocin

Answer and Explanation

The Correct Answer is D

A. Progesterone plays a significant role in maintaining pregnancy and preparing the breasts for lactation, but it is not responsible for the milk let-down reflex.
B. Estrogen helps with breast development and ductal growth during pregnancy, but it does not trigger the milk let-down reflex.
C. Prolactin is responsible for milk production (lactogenesis) but not for the actual release of milk from the breast.
D. Oxytocin is the hormone responsible for the milk let-down reflex, which causes milk to be released from the milk glands into the nipple when the baby suckles. It also promotes uterine contractions after childbirth.

A. Birth trauma typically refers to physical injuries sustained during delivery, such as bruising or fractures. Bluish markings across the lower back are not indicative of birth trauma.
B. Stork bites are reddish or pinkish marks, usually found on the nape of the neck, eyelids, or forehead. They are vascular birthmarks and are not bluish in color.
C. Milia refers to small white cysts found on a newborn's face, usually on the nose, chin, or forehead, caused by blocked sebaceous glands. It is not associated with bluish markings.
D. Mongolian spots are bluish or purplish birthmarks commonly found on the lower back or buttocks of infants, especially those with darker skin. These are normal and typically fade over time.

A. reduces lochia B. promotes uterine involution C. improves pelvic floor tone D. alleviates perineal pain

Correct Answer is C

Explanation

A. Lochia is the normal postpartum vaginal discharge of blood and tissue, and its duration or volume is not affected by Kegel exercises.
B. Uterine involution ,the shrinking of the uterus to its pre-pregnancy size ,is a natural physiological process and is not influenced by Kegel exercises.
C. Kegel exercises specifically target the pelvic floor muscles, which may be weakened during pregnancy and childbirth. These exercises help strengthen the muscles, support pelvic organs, and prevent issues such as urinary incontinence.
D. While improved muscle tone may eventually support healing, these exercises are not a direct method for pain relief.
