Final answer:
A nurse caring for a newborn whose mother is infected with hepatitis should take precautions to prevent infection and follow protocols for managing the situation.
Step-by-step explanation:
A nurse caring for a newborn whose mother is infected with hepatitis should take precautions to prevent infection. The virus can be transmitted through blood, body fluids, and damaged skin. The nurse should wear gloves and face protection, use disposable syringes and needles, and wash exposed skin with soap and water. The CDC recommends disinfecting surfaces with a 10% bleach solution. Post-exposure treatment, including hepatitis B immunoglobulin (HBIG) and vaccination, may be used in case of exposure to the virus.
