The nurse is caring for a neonate undergoing phototherapy. What action does the nurse include on the infant's care plan?

Choice A: This is incorrect because both physiological and nonphysiological jaundice result from breakdown of erythrocytes. Jaundice is caused by the accumulation of bilirubin, a yellow pigment that is produced when red blood cells are destroyed. However, the rate and extent of hemolysis differ between the two types of jaundice.

Choice B: This is incorrect because kernicterus is a rare and serious complication of jaundice, not a usual outcome. Kernicterus occurs when bilirubin levels are very high and the pigment deposits in the brain, causing neurological damage. It can affect both physiological and nonphysiological jaundice, but it is more likely to occur in nonphysiological jaundice due to higher bilirubin levels and underlying conditions.

Choice C: This is incorrect because both physiological and nonphysiological jaundice begin at the head and progress down the body. This is because bilirubin accumulates in areas with high fat content, such as the skin, eyes, and brain. The distribution of jaundice depends on the level of bilirubin in the blood, not on the type of jaundice.

Choice D: This is the correct answer because nonphysiological jaundice appears in the first 24 hours of life, whereas physiological jaundice appears after the first 24 hours of life. Nonphysiological jaundice is caused by factors that increase hemolysis or impair bilirubin metabolism or excretion, such as blood group incompatibility, infection, liver disease, or enzyme deficiency. Physiological jaundice is caused by normal adaptation processes that occur after birth, such as increased red blood cell turnover, immature liver function, and delayed intestinal flora colonization.

Choice a) Breasts firm and tender is incorrect because this is not a sign of normal involution, but rather a sign of breast engorgement, which is a common problem in the first few weeks of breastfeeding. Breast engorgement occurs when thE breasts become overfilled with milk, causing them to feel hard, swollen, painful, and warm. It can be prevented or relieved by frequent and effective breastfeeding, applying warm or cold compresses, massaging the breasts, expressing some milk, and wearing a supportive bra.

Choice b) Episiotomy slightly red and puffy is incorrect because this is not a sign of normal involution, but rather a sign of inflammation or infection of the perineal wound. An episiotomy is a surgical cut made in the perineum (the area between the vagina and the anus) to enlarge the vaginal opening during delivery. It can take several weeks to heal and may cause pain, swelling, bruising, bleeding, or discharge. It can be cared for by keeping the area clean and dry, applying ice packs or witch hazel pads, taking painkillers or sitz baths, and avoiding constipation or straining.

Choice c) Fundus below the symphysis and not palpable is correct because this is a sign of normal involution, which is the process of the uterus returning to its pre-pregnancy size and shape after delivery. The fundus is the upper part of the uterus that can be felt through the abdomen. Immediately after delivery, the fundus is about the size of a grapefruit and can be felt at or above the umbilicus (the navel). It gradually descends about one fingerbreadth per day until it reaches the level of the symphysis pubis (the joint where the two pubic bones meet) by about 10 days postpartum. By 14 days postpartum, the fundus should be below the symphysis and not palpable.

Choice d) Moderate bright red lochial flow is incorrect because this is not a sign of normal involution, but rather a sign of excessive or prolonged bleeding after delivery. Lochia is the vaginal discharge that consists of blood, mucus, and tissue from the lining of the uterus. It changes in color and amount over time, from red to pink to brown to yellow to white. The normal lochia flow should be scant to moderate in amount, dark red to brown in color, and last for about 4 to 6 weeks postpartum. A moderate bright red lochial flow on day 14 postpartum may indicate that the uterus is not contracting well or that there is an infection or retained placental tissue in the uterus.
