A nurse is assisting a client with breastfeeding her newborn.
The nurse should explain that which of the following reflexes will initiate sucking?
Rooting.
Moro.
Stepping.
Babinski.
The Correct Answer is A
Choice A rationale:
The rooting reflex is the newborn's natural response to touch around their mouth, particularly the cheek. When the cheek is touched, the infant will turn their head in that direction and open their mouth, initiating the sucking reflex. This reflex helps the newborn find the breast or bottle for feeding.
Choice B rationale:
The Moro reflex is not associated with the initiation of sucking. The Moro reflex is a startle reflex that involves extending and retracting the arms and legs when a newborn feels a sudden loss of support or experiences a loud noise.
Choice C rationale:
The stepping reflex is not related to the initiation of sucking. The stepping reflex is an automatic response that occurs when you hold a newborn upright with their feet touching a surface, causing them to make stepping movements.
Choice D rationale:
The Babinski reflex involves the extension and fanning out of the toes when the sole of the foot is stroked. It is not associated with the initiation of sucking.

Correct Answer is A
Explanation
Choice A rationale:
When a pregnant client is Rh negative and the newborn is Rh positive, it can lead to Rh incompatibility issues. This occurs when fetal Rh-positive red blood cells enter the maternal circulation during pregnancy or childbirth, causing the mother's immune system to produce antibodies against Rh-positive blood cells. To prevent Rh sensitization, Rho(D) immune globulin is administered to Rh-negative pregnant clients at specific times during pregnancy and postpartum. This administration is essential to prevent hemolytic disease of the newborn in future pregnancies. The Rho(D) immune globulin prevents the mother's immune system from developing antibodies against Rh-positive blood cells, ensuring that the current pregnancy and future pregnancies remain safe. Therefore, choice A is the correct answer.
Choice B rationale:
If the client is Rh positive and the newborn is Rh positive, there is no need for Rho(D) immune globulin administration. Rh incompatibility issues only occur when the mother is Rh negative, and the newborn is Rh positive. Therefore, choice B is not the correct answer.
Choice C rationale:
When both the client and the newborn are Rh negative, there is no risk of Rh incompatibility, and therefore, Rho(D) immune globulin administration is unnecessary. This situation is not a reason to administer Rho(D) immune globulin. Choice C is not the correct answer.
Choice D rationale:
If the client is Rh positive and the newborn is Rh negative, there is no risk of Rh incompatibility, and Rho(D) immune globulin administration is not required in this scenario. Choice D is not the correct answer.
Correct Answer is A
Explanation
Choice A rationale:
The purpose of administering vitamin K to a newborn is to prevent bleeding. Vitamin K plays a crucial role in blood clotting. Newborns often have lower levels of vitamin K, which can make them more susceptible to bleeding disorders, such as hemorrhagic disease of the newborn (HDN). HDN can lead to serious bleeding complications, including intracranial hemorrhage, which can be life-threatening.
Choice B rationale:
Hyperbilirubinemia is not the primary purpose of administering vitamin K. While vitamin K can indirectly help in preventing jaundice (hyperbilirubinemia) by reducing the risk of bleeding that may lead to hemolysis, it is not the primary aim of vitamin K administration.
Choice C rationale:
Potassium deficiency (hypokalemia) is not a primary concern related to vitamin K administration. Vitamin K is specifically administered to prevent bleeding disorders and not to address potassium levels.
Choice D rationale:
Infection is not related to the administration of vitamin K. Vitamin K is not used to prevent or treat infections in newborns; its primary role is in blood clotting.
