The hormone responsible for the production of breast milk is:

A.

Prolactin.

B.

Progesterone.

C.

Hindmilk.

D.

Foremilk.

Answer and Explanation

The Correct Answer is A

Choice A rationale: Prolactin is the hormone responsible for the production of breast milk. It is produced by the anterior pituitary gland and stimulates the mammary glands to produce milk. Prolactin levels increase during pregnancy and breastfeeding to ensure a sufficient milk supply.

Choice B rationale: Progesterone plays a role in preparing the breast tissue for lactation during pregnancy, but it does not directly stimulate milk production.

Choice C rationale: Hindmilk is the milk produced later in a feeding session, which is richer in fat and calories. It is not a hormone and does not stimulate milk production.

Choice D rationale: Foremilk is the initial milk released during breastfeeding, which is higher in water content. It is also not a hormone and does not stimulate milk production.

Correct Answer is A

Explanation

Choice A rationale

A macrosomic baby, or a baby with a high birth weight, can stretch the uterus significantly, increasing the risk of postpartum hemorrhage. The overstretched uterus may not contract effectively after birth, leading to excessive bleeding.

Choice B rationale

Uterine involution refers to the process of the uterus returning to its pre-pregnancy size. Effective uterine involution typically reduces the risk of hemorrhage, rather than increasing it, as the contracting uterus helps compress blood vessels and control bleeding.

Choice C rationale

A first-degree laceration is a minor perineal tear that typically heals without significant intervention. While it can cause some bleeding, it is usually not sufficient to lead to postpartum hemorrhage. More severe lacerations (third or fourth degree) pose higher risks.

Choice D rationale

Endometriosis is a condition where tissue similar to the lining inside the uterus grows outside it. It does not directly increase the risk of postpartum hemorrhage. The condition primarily causes pain and fertility issues rather than acute bleeding post-delivery.

Explanation

  1. Jitteriness: This can be a sign of hypoglycemia in a newborn, and it may also be seen in Neonatal Abstinence Syndrome (NAS) due to withdrawal symptoms.
  2. Lethargy: Lethargy is common in hypoglycemia (due to low energy reserves) and can also be seen in Neonatal Abstinence Syndrome due to withdrawal effects.
  3. Poor Feeding: Hypoglycemia may cause poor feeding due to the lack of energy, and Neonatal Abstinence Syndrome can cause feeding difficulties because of withdrawal symptoms.
  4. Jaundice: Jaundice is a hallmark sign of Neonatal Jaundice, typically due to elevated bilirubin levels.
  5. Loose Stool: Loose stool can be a sign of Neonatal Abstinence Syndrome, as gastrointestinal disturbances are common in withdrawal. It is not typically associated with hypoglycemia or neonatal jaundice.
