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:
Preterm infant.
Female infant.
GBS status of mother.
Cesarean section.
The Correct Answer is D
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.

Correct Answer is A
Explanation
Choice A Reason: Docusate sodium (Colace). This is because docusate sodium is a stool softener that can prevent constipation and straining during defecation, which can aggravate or impair the healing of a perineal laceration. A fourth-degree perineal laceration is a severe tear that extends through the skin, muscles, perineal body, and anal sphincter into the rectal mucosa. It can occur during vaginal delivery due to factors such as fetal macrosomia, forceps use, or episiotomy.
Choice B Reason: Bromocriptine (Parlodel). This is an inappropriate medication for a postpartum client with a fourth- degree perineal laceration, as it has no effect on wound healing or pain relief. Bromocriptine is a dopamine agonist that can suppress lactation by inhibiting prolactin secretion. It is used for women who do not wish to breastfeed or who have medical contraindications to breastfeeding.
Choice C Reason: Ferrous sulfate (Feosol). This is an unnecessary medication for a postpartum client with a fourth- degree perineal laceration, unless she has iron deficiency anemia. Ferrous sulfate is an iron supplement that can treat or prevent anemia by increasing hemoglobin production and oxygen-carrying capacity. Anemia can occur in the postpartum period due to blood loss during delivery or poor nutritional intake during pregnancy.
Choice D Reason: Methylergonovine (Methergine). This is an irrelevant medication for a postpartum client with a fourth-degree perineal laceration, as it does not affect wound healing or pain relief. Methylergonovine is an ergot alkaloid that can stimulate uterine contractions and reduce postpartum bleeding. It is used for women who have uterine atony or hemorrhage.
Correct Answer is D
Explanation
Choice A Reason: Retained placental fragments. This is an incorrect answer that refers to a different cause of late postpartum hemorrhage, which is less common than uterine atony. Retained placental fragments are pieces of placenta that remain atached to the uterine wall after delivery, which prevent uterine contraction and involution, and provide a source of bleeding and infection. Retained placental fragments can be caused by abnormal placentation (such as placenta accreta), manual removal of placenta, or incomplete separation of placenta.
Choice B Reason: Cervical or vaginal lacerations. This is an incorrect answer that refers to a different cause of late postpartum hemorrhage, which is more likely to cause early postpartum hemorrhage than late postpartum hemorrhage. Cervical or vaginal lacerations are tears or cuts in the cervix or vagina that occur during delivery, which can cause bleeding from the damaged blood vessels. Cervical or vaginal lacerations can be caused by rapid or instrumental delivery, large or malpositioned fetus, or episiotomy.
Choice C Reason: Uterine inversion. This is an incorrect answer that refers to a different cause of late postpartum hemorrhage, which is rare and life-threatening. Uterine inversion is a condition where the uterus turns inside out and protrudes through the cervix and vagina after delivery, which can cause massive bleeding and shock. Uterine inversion can be caused by excessive traction on the umbilical cord, fundal pressure, or uterine relaxation.
Choice D Reason: Uterine atony. This is because uterine atony is a condition where the uterus fails to contract and retract after delivery, which leads to bleeding from the placental site. Uterine atony is the most common cause of late postpartum hemorrhage, accounting for about 75% of cases. Late postpartum hemorrhage is excessive bleeding from the uterus or genital tract that occurs more than 24 hours but less than 12 weeks after delivery. Late postpartum hemorrhage can be caused by retained placental fragments, subinvolution of the uterus, infection, or coagulation disorders.
