The student nurse learns that the hormone necessary for milk production is

Estrogen.

Prolactin.

Progesterone.

Lactogen.

Answer and Explanation

The Correct Answer is B

The correct answer is choice B. Prolactin.

Choice A reason:

Estrogen. Estrogen is a hormone that plays a role in the development of the mammary glands and the ductal system during pregnancy. However, estrogen does not directly produce milk.

In fact, high levels of estrogen during pregnancy inhibit milk secretion by blocking prolactin. Therefore, estrogen is not the hormone necessary for milk production. • Choice B reason:

Prolactin. Prolactin is the hormone responsible for the production of breast milk. Prolactin is secreted by the pituitary gland in response to suckling or nipple stimulation. Prolactin levels rise during pregnancy and peak after delivery, when the sudden drop in estrogen and progesterone allows prolactin to take over and initiate lactation. Therefore, prolactin is the hormone necessary for milk production. • Choice C reason:

Progesterone. Progesterone is a hormone that also contributes to the development of the mammary glands and the alveoli during pregnancy. However, like estrogen, progesterone does not directly produce milk. Progesterone also inhibits milk secretion by blocking prolactin during pregnancy. Therefore, progesterone is not the hormone necessary for milk production. •

Choice D reason:

Lactogen. Lactogen is not a hormone, but a general term for any substance that stimulates lactation. There are different types of lactogens, such as human placental lactogen (hPL), which is produced by the placenta during pregnancy and has some lactogenic effects on the mammary glands. However, hPL is not the main hormone responsible for milk production. That role belongs to prolactin. Therefore, lactogen is not the hormone necessary for milk production.

Correct Answer is B

Explanation

Choice A reason:

Inspecting if the urethral opening appears circular. This is a correct action for the nurse to do, as it helps to identify any abnormalities in the urethral opening, such as hypospadias or epispadias, which are congenital defects where the opening is located on the underside or the top of the penis, respectively. • Choice B reason:

Retracting the foreskin over the glans to assess for secretions. This is an incorrect action for the nurse to avoid, as it can cause pain, bleeding, and infection in the newborn. The foreskin is usually adhered to the glans in newborns and should not be forcibly retracted. It will gradually loosen over time and can be retracted by the child himself when he is older. •

Choice C reason:

Palpating if testes are descended into the scrotal sac. This is a correct action for the nurse to do, as it helps to detect any undescended testes, which are more common in preterm infants and can increase the risk of infertility and testicular cancer later in life. • Choice D reason:

Inspecting the genital area for irritated skin. This is a correct action for the nurse to do, as it helps to identify any signs of diaper rash, fungal infection, or allergic reaction in the newborn's skin.

A. immunizations for high-risk infants and children. B. screening for infants with developmental disorders. C. supplemental food supplies to low-income pregnant or breastfeeding women. D. well-child examinations for infants and children living at the poverty level.

Correct Answer is C

Explanation

Choice A reason:

This is incorrect because WIC does not provide immunizations for high-risk infants and children. Immunizations are provided by other health care services, which WIC may refer participants to.

Choice B reason:

This is incorrect because WIC does not screen for infants with developmental disorders. WIC provides nutrition education and referrals to other health and social services but does not diagnose or treat any medical conditions.

Choice C reason:

This is correct because WIC provides supplemental food supplies to low-income pregnant or breastfeeding women, as well as infants and children up to age 5 who are at nutritional risk. The food packages are designed to meet the special nutritional needs of the participants and include items such as fruits, vegetables, milk, cheese, cereal, bread, juice, peanut butter, eggs, and infant formula.

Choice D reason:

This is incorrect because WIC does not provide well-child examinations for infants and children living at the poverty level. WIC may refer participants to other health care services that provide such examinations but do not conduct them themselves.
