You know that _________ promotes bonding, helps infant maintain their temperature and promotes involution.

A. Mother Rh-, baby Rh+:
Rh immune globulin (RhoGAM) is given to Rh-negative mothers after childbirth if the baby is Rh-positive. This is to prevent the mother from developing antibodies against Rh-positive blood cells, which could affect future pregnancies. If the mother’s immune system recognizes Rh-positive cells as foreign, it may start producing antibodies that can cross the placenta and harm future Rh-positive fetuses, potentially leading to hemolytic disease of the newborn. Administering RhoGAM prevents this sensitization from occurring.

B. Mother Rh-, baby Rh-:
If the mother is Rh-negative and the baby is also Rh-negative, there is no risk of Rh incompatibility. Since there is no Rh-positive blood in the mix, the mother will not develop antibodies against Rh-positive cells. Therefore, Rh immune globulin is not needed in this situation.

C. Mother Rh+, baby Rh+:
If the mother is Rh-positive, there is no risk of Rh incompatibility regardless of the baby’s Rh status. Rh-positive mothers do not produce antibodies against Rh-positive blood cells, so RhoGAM is unnecessary in this scenario.

D. Mother Rh+, baby Rh-:
Again, since the mother is Rh-positive, there is no risk of sensitization, even if the baby is Rh-negative. In this situation, the mother's immune system will not generate antibodies against Rh-negative blood cells, and RhoGAM is not needed.

A) Bacteria that synthesize vitamin K are not present in the newborn's intestinal tract:
Newborns are born with a sterile gastrointestinal tract, meaning they do not yet have the intestinal bacteria necessary to synthesize vitamin K. Vitamin K is essential for the activation of clotting factors, and without sufficient vitamin K, newborns are at risk for bleeding disorders, particularly a condition known as vitamin K deficiency bleeding (VKDB). Administering vitamin K by injection shortly after birth ensures the baby has adequate levels to prevent bleeding.
B) Vitamin K prevents the synthesis of prothrombin in the liver and must be given by injection:
This statement is incorrect. Vitamin K does not prevent the synthesis of prothrombin; rather, it is essential for the liver to synthesize clotting factors, including prothrombin. The injection of vitamin K in newborns is necessary to provide adequate levels of vitamin K to support proper blood clotting, as newborns cannot produce enough on their own at birth due to the absence of gut bacteria that normally produce it.

C) The supply of vitamin K is inadequate for at least 12 months, and the newborn must be supplemented throughout infancy:
While it is true that newborns have a limited supply of vitamin K at birth, this deficiency is typically addressed with a single injection given shortly after birth. Supplementing vitamin K throughout infancy is generally not required, as the infant's gastrointestinal tract will start to develop the necessary bacteria to synthesize vitamin K within the first few weeks to months of life. The first dose of vitamin K prevents bleeding disorders, and in most cases, additional supplementation is not necessary.

D) Most mothers have a diet deficient in vitamin K, which results in the infant being deficient:
While maternal diet does play a role in the newborn's initial vitamin K levels, it is not the primary reason for the deficiency. Vitamin K deficiency in newborns is primarily due to the lack of gut bacteria necessary to produce it, rather than maternal diet. The practice of administering vitamin K to all newborns ensures that they receive adequate levels to prevent bleeding, regardless of maternal dietary intake.
