Which plans of care should be made for a newborn of a mother who tested positive for hepatitis B?

The correct plan of care for a newborn whose mother has tested positive for hepatitis B is to administer hepatitis B immune globulin (HBIG) at birth. This is a crucial intervention that helps provide immediate passive immunity against the hepatitis B virus. The administration of HBIG, ideally given within 12 hours of birth, along with the first dose of the hepatitis B vaccine, greatly reduces the risk of the infant acquiring the virus from the infected mother.

This combined approach is essential for protecting the newborn, as hepatitis B can lead to chronic infection and long-term health issues. This intervention not only helps in the immediate protection of the infant but also decreases the risk of transmission in the early stages of life, making it a standard practice in the care of infants born to mothers with hepatitis B.

Other options, while relevant to the overall care and management of infants, do not provide the immediate protective measures that HBIG offers. Hepatitis B screening is helpful but would typically be conducted on the mother during pregnancy, not the newborn immediately at birth. Isolation of the infant is unnecessary as hepatitis B is transmitted through bodily fluids, not through casual contact. Universal precautions are always advisable in healthcare settings but do not specifically address the urgent need for the newborn to receive HB
