A nurse is caring for a newborn whose mother is positive for the hepatitis B surface antigen. Which of the following treatments should the infant receive?
The hepatitis B vaccine is monthly until the newborn tests negative for the hepatitis B surface antigen
Hepatitis B immune globulin and the hepatitis B vaccine within 12 hours of birth
Hepatitis B immune globulin at 1 week followed by the hepatitis B vaccine monthly for 6 months
The hepatitis B vaccine at 24 hours followed by hepatitis B immune globulin every 12 hours for 3 days
The Correct Answer is B
Choice A rationale:
Administering the hepatitis B vaccine monthly until the newborn tests negative for the hepatitis B surface antigen is not the appropriate treatment for a newborn whose mother is positive for the hepatitis B surface antigen. Immediate intervention is required to prevent transmission.
Choice B rationale:
The newborn of a mother who is positive for the hepatitis B surface antigen should receive hepatitis B immune globulin (HBIG) and the hepatitis B vaccine within 12 hours of birth. HBIG provides passive immunity to the baby while the vaccine stimulates active immunity.
Choice C rationale:
Administering hepatitis B immune globulin for 1 week followed by the hepatitis B vaccine monthly for 6 months is not the correct treatment plan. Immediate intervention is necessary to prevent transmission to the newborn.
Choice D rationale:
Administering the hepatitis B vaccine at 24 hours followed by hepatitis B immune globulin every 12 hours for 3 days is not the appropriate treatment. Hepatitis B immune globulin should be given within 12 hours of birth, not over several days.

Correct Answer is B
Explanation
Choice A rationale: An increase in breast milk production is a normal physiological response during breastfeeding and does not indicate mastitis.
Choice B rationale: Mastitis is an inflammation of the breast tissue, usually caused by infection. It commonly occurs in breastfeeding women and is characterized by redness, warmth, swelling, and pain in one breast. The affected breast may also be tender and sore to the touch.
Choice C rationale: Swelling in both breasts is a common occurrence during the early days of breastfeeding as the milk supply adjusts to the baby's needs. It is not specific to mastitis.
Choice D rationale: Cracked and bleeding nipples can be a result of improper latch or positioning during breastfeeding, but they are not specific to mastitis.
Correct Answer is D
Explanation
A. Breast engorgement typically occurs around days 3 to 5 postpartum, so encouraging frequent nursing at 14 hours postpartum will not impact milk production at this stage.
B. A temperature of 37.7°C (100°F) is a normal postpartum finding due to dehydration and hormonal changes. It does not require reporting unless it exceeds 38°C (100.4°F).
C. Increasing IV fluids is not necessary unless there is evidence of dehydration or another medical indication.
D. A slightly deviated fundus suggests bladder distension, which can interfere with uterine involution. Asking the client to empty her bladder helps the uterus contract properly and prevents complications such as postpartum hemorrhage.
