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: Episodes of hypoglycemia and hyperglycemia. This is because episodes of hypoglycemia and hyperglycemia are common complications of diabetes during pregnancy, which can affect both the mother and the fetus. Hypoglycemia is a condition where the blood glucose level drops below the normal range, which can cause symptoms such as sweating, trembling, hunger, confusion, or loss of consciousness. Hyperglycemia is a condition where the blood glucose level rises above the normal range, which can cause symptoms such as thirst, polyuria, fatigue, blurred vision, or ketoacidosis. Diabetes during pregnancy requires careful monitoring and management of blood glucose levels to prevent adverse outcomes such as fetal macrosomia, congenital anomalies, stillbirth, or neonatal hypoglycemia.
Choice B Reason: Postpartum hemorrhage. This is an incorrect answer that refers to a different complication that may occur after delivery, not during pregnancy. Postpartum hemorrhage is excessive bleeding from the uterus or genital tract after delivery, which can cause hypovolemic shock, anemia, or death. Postpartum hemorrhage can be caused by uterine atony, retained placenta, lacerations, or coagulation disorders.
Choice C Reason: Cerebrovascular accident (CVA). This is an incorrect answer that indicates a rare and severe complication that may occur during or after pregnancy, not specifically related to diabetes. CVA is also known as stroke, which is an interruption of blood flow to the brain due to ischemia or hemorrhage, which can cause neurological deficits or death. CVA can be caused by hypertension, preeclampsia-eclampsia, thrombophilia, or vascular malformations.
Choice D Reason: Acute vasospasm. This is an incorrect answer that suggests a different condition that may occur during pregnancy, not associated with diabetes. Acute vasospasm is also known as Raynaud's phenomenon, which is a disorder of blood vessels that causes them to narrow and reduce blood flow to the extremities in response to cold or stress, which can cause pain, numbness, or color changes. Acute vasospasm can be triggered by smoking, medications, or autoimmune diseases.

Correct Answer is B
Explanation
Choice A Reason: Physiologic anemia due to maternal increased plasma volume. This is an incorrect answer that refers to a different condition that affects hemoglobin levels, not blood pressure. Physiologic anemia is a condition where the maternal plasma volume increases more than the red blood cell mass during pregnancy, which dilutes the hemoglobin concentration and lowers the hematocrit value. Physiologic anemia does not cause significant symptoms or complications in pregnant women, as it is an adaptive mechanism that enhances oxygen delivery and prevents fluid overload.
Choice B Reason: Pressure of the gravid uterus on the maternal inferior vena cava and aorta. This is because this statement explains the cause of supine hypotensive syndrome, which is a condition where lying flat on the back causes compression of the major blood vessels by the gravid uterus, which reduces venous return and cardiac output, which lowers blood pressure and perfusion to vital organs. Supine hypotensive syndrome can cause symptoms such as dizziness, lightheadedness, nausea, pallor, or syncope in pregnant women, especially in the third trimester.
Choice C Reason: Pressure of the presenting fetal part on the maternal diaphragm. This is an incorrect answer that indicates a different condition that affects respiratory function, not blood pressure. Pressure of the presenting fetal part on the maternal diaphragm is a result of cephalic engagement or lightening, which occurs when the fetal head descends into the pelvis and occupies more space in the abdominal cavity. Pressure of the presenting fetal part on the maternal diaphragm can cause symptoms such as dyspnea, heartburn, or rib pain in pregnant women.
Choice D Reason: A 50% increase in maternal blood volume during pregnancy. This is an incorrect answer that describes a normal physiological change that occurs during pregnancy, not a cause of supine hypotensive syndrome. A 50% increase in maternal blood volume during pregnancy is due to increased production of plasma and red blood cells, which helps meet the increased oxygen and nutrient demands of the fetus and placenta, and prepares the mother for blood loss during delivery. A 50% increase in maternal blood volume during pregnancy does not cause hypotension or dizziness in pregnant women.
