On her second postpartum day, the mother of a newborn says, “The doctor says the baby has physiologic jaundice.
Even though it is supposed to be normal, I don’t understand why it occurs.” Which fact regarding physiologic jaundice should form the basis of the nurse’s response?
It is caused by an increase in neonatal metabolism.
It is related to the destruction of fetal red blood cells.
It is caused by an antigen-antibody reaction.
It is related to the immaturity of the reticuloendothelial system.
The Correct Answer is B
Physiologic jaundice is a common condition in newborns that occurs when the baby’s blood contains an excess of bilirubin, a yellow pigment produced during the normal breakdown of red blood cells.In the womb, the mother’s liver removes bilirubin for the baby, but after birth the baby’s own liver must take over this function.Because the baby has more red blood cells than an adult and their liver is still immature, they may not be able to process all the bilirubin and it may build up in their skin and eyes, causing a yellowish appearance.
Choice A is wrong because it is not an increase in neonatal metabolism that causes physiologic jaundice, but rather a decrease in hepatic metabolism of bilirubin.
Choice C is wrong because it describes a different type of jaundice called hemolytic jaundice, which occurs when there is an incompatibility between the blood types of the mother and the baby, leading to an immune reaction that destroys the baby’s red blood cells faster than they can be replaced.
Choice D is wrong because it confuses the reticuloendothelial system with the hepatic system.
The reticuloendothelial system is a network of cells and tissues that are involved in immune responses and phagocytosis (the ingestion of foreign particles or cells).
The hepatic system is the system of organs and structures that are involved in liver functions, such as bile production and detoxification.
Normal ranges for bilirubin levels in newborns are 1 to 12 mg/dL (17 to 205 micromol/L) for total bilirubin and 0.2 to 1.4 mg/dL (3 to 24 micromol/L) for direct bilirubin.
Physiologic jaundice usually peaks at 3 to 5 days after birth and resolves by 2 weeks of age.
It does not require treatment unless the bilirubin levels are very high or rising rapidly, which may indicate a more serious condition or a risk of brain damage.

Correct Answer is D
Explanation
Braxton Hicks contractions are irregular, painless uterine contractions that occur throughout pregnancy, but are more noticeable in the third trimester.They do not indicate labor, but rather help in softening and ripening the cervix.
Choice A is wrong because the patient does not need to time the contractions unless they become regular, painful, and closer together, which are signs of true labor.
Choice B is wrong because documenting fetal activity daily is not related to Braxton Hicks contractions.Fetal activity is monitored to assess fetal well-being and detect any signs of fetal distress.
Choice C is wrong because losing the mucus plug is also not related to Braxton Hicks contractions.The mucus plug is a thick plug of mucus that seals the cervical canal during pregnancy and may be expelled before or during labor.
Correct Answer is D
Explanation
The correct answer is choice D. The fluid that the mother has in her breasts before the milk comes in is called colostrum, which is rich in antibodies and nutrients that the baby needs.
It also helps to prevent jaundice by stimulating the baby’s bowel movements.
Therefore, the nurse should encourage the mother to breastfeed as soon as possible after birth and explain the benefits of colostrum.
Choice A is wrong because it discourages breastfeeding and may interfere with milk production and bonding.
Choice B is wrong because it implies that breastfeeding is only a skill and not a natural process that benefits both the mother and the baby.
Choice C is wrong because it focuses on the emotional aspect of breastfeeding and not the physiological one.
While breastfeeding may enhance the closeness between the mother and the baby, it is not the only reason to breastfeed.
