Answer to Question 1

ANS: A
Vitamin K is administered to prevent hemorrhagic disease of the newborn. Vitamin K is synthesized by the intestinal flora. Because the newborn's intestine is sterile and breast milk is low in vitamin K, a supplemental source must be supplied. The purpose is not to enhance the immune response, prevent bacterial infection, or maintain nutritional status. The major function of vitamin K is to catalyze the liver synthesis of prothrombin, which is needed for blood clotting and coagulation.

Answer to Question 2

ANS: A
Maintaining a patent airway is the primary objective in the care of the newborn. The nurse uses a bulb syringe to clear the pharynx, followed by the nasal passages. Conserving the newborn's body heat and maintaining a stable body temperature are important, but a patent airway must be established first. These are important functions, but physiologic stability is the first priority in the immediate care of the newborn.
