An nurse explains to new parents that their infant has developed Transient Tachypnea of the Newborn (TTN). The nurse understands that risk factors for TTN include which of the following?
Select one:

Choice A Reason: Preterm infant. This is an incorrect answer that confuses TTN with another respiratory condition called respiratory distress syndrome (RDS). RDS is a serious condition where the newborn's lungs are immature and lack sufficient surfactant, which is a substance that reduces surface tension and prevents alveolar collapse. RDS can cause respiratory distress, hypoxia, acidosis, and organ failure. It is more common in preterm infants, especially those born before 37 weeks' gestation.

Choice B Reason: Female infant. This is an incorrect answer that has no evidence or rationale to support it. TTN does not have a gender preference or difference in incidence or severity.

Choice C Reason: GBS status of mother. This is an incorrect answer that relates to another respiratory complication called early-onset neonatal sepsis (EONS). EONS is a bacterial infection that occurs within 72 hours after birth, which can affect multiple organs and systems in the newborn. EONS can be caused by group B streptococcus (GBS), which is a common bacterium that colonizes in some women's vagina or rectum. GBS can be transmited to the newborn during delivery and cause pneumonia, meningitis, or septic shock.

Choice D Reason: Cesarean section. This is because cesarean section is a risk factor for TTN, which is a mild respiratory problem that results from delayed clearance of fetal lung fluid after birth. TTN causes rapid breathing, nasal flaring, grunting, and mild cyanosis. It usually resolves within 24 to 48 hours after birth. Cesarean section can increase the risk of TTN because it bypasses the normal process of labor, which helps squeeze out some of the fluid from the fetal lungs.

Choice A Reason: Applying Vaseline or lotion to newborn to maximize light absorption. This is an incorrect answer that indicates a contraindicated and harmful intervention that can interfere with phototherapy. Applying Vaseline or lotion to newborn can create a barrier or a reflective surface that can reduce the exposure and penetration of light to the skin, which can decrease the efficacy of phototherapy. Applying Vaseline or lotion to newborn can also cause skin irritation, infection, or burns, as it can trap heat and moisture under the light source.

Choice B Reason: Reducing the amount of fluid intake to 8 ounces daily. This is an incorrect answer that suggests a detrimental and dangerous intervention that can impair phototherapy. Reducing the amount of fluid intake to 8 ounces daily can cause dehydration, hypoglycemia, or electrolyte imbalance in newborns, which can worsen jaundice and increase the risk of complications such as kernicterus (brain damage due to high bilirubin levels). Reducing the amount of fluid intake to 8 ounces daily can also decrease the excretion of bilirubin through urine or stool, which can counteract the effect of phototherapy.

Choice C Reason: Keeping the newborn in the supine position. This is an incorrect answer that implies an incomplete and inadequate intervention that can limit phototherapy. Keeping the newborn in the supine position is a nursing action that involves placing the newborn on their back, which can expose their anterior body surface to light.

However, keeping the newborn in the supine position alone is not sufficient for phototherapy, as it does not expose their posterior body surface to light. The nurse should also reposition the newborn frequently to expose different body parts to light, such as their sides or abdomen.

Choice D Reason: Feeding every 3 hours to maximize intake of fluids and output. This is because feeding every 3 hours is a nursing intervention that can enhance the effectiveness and safety of phototherapy, which is a treatment that uses blue or white light to reduce the level of bilirubin in the blood. Bilirubin is a yellow pigment that is produced when red blood cells are broken down, which can cause jaundice (yellowish discoloration of the skin and mucous membranes) if it accumulates in excess. Phototherapy works by converting bilirubin into a water-soluble form that can be excreted through urine or stool. Feeding every 3 hours can increase the intake of fluids and calories, which can promote hydration, nutrition, and elimination of bilirubin.
