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 A
Explanation
Choice A rationale:
A newborn can lose up to 10% of their birth weight in the first few days after birth, which is considered normal. By 7-14 days of age, the baby should have regained their birth weight if breastfeeding effectively.
Choice B rationale:
Gaining 0.25 oz (7 grams) per day after the fourth day of life is not a standard guideline for assessing effective breastfeeding.
Choice C rationale:
Expecting the baby to have less than 5 wet diapers per day after the fourth day of life may indicate dehydration or inadequate breastfeeding, which is not a sign of effective breastfeeding.
Choice D rationale:
Expecting the baby to feed constantly during the first week of life is not necessarily an indicator of effective breastfeeding. While frequent feeding is normal in the early days, the baby should be able to effectively feed and show signs of satiety after nursing.
Correct Answer is D
Explanation
Choice A rationale:
Uterine enlargement greater than expected for gestational age is not a typical finding in a possible ectopic pregnancy. An ectopic pregnancy occurs when the fertilized egg implants outside the uterus, usually in the fallopian tube, and the uterus does not enlarge normally.
Choice B rationale:
Copious vaginal bleeding is not a typical finding in a possible ectopic pregnancy. Vaginal bleeding can occur, but it is not usually copious.
Choice C rationale:
Severe nausea and vomiting are not typically associated with a possible ectopic pregnancy. Nausea and vomiting are common symptoms in early pregnancy, but they are not specific to an ectopic pregnancy.
Choice D rationale:
Pelvic pain is a common finding in a possible ectopic pregnancy. The pain is often sharp, and unilateral, and may be located on one side of the lower abdomen or pelvis.
