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.

Answer and Explanation

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 D

Explanation

Choice A Reason: Daily weight. This is an incorrect answer that indicates a valid parameter to assess hydration status. Daily weight is a measure of the body mass that can reﬂect changes in ﬂuid balance. Daily weight can help detect ﬂuid loss or gain in premature infants, who are more prone to dehydration or overhydration due to immature renal function and high insensible water loss.

Choice B Reason: Consistency of stool. This is an incorrect answer that indicates a valid parameter to assess hydration status. Consistency of stool is a measure of the texture and form of feces that can reﬂect changes in ﬂuid intake and absorption. Consistency of stool can help identify diarrhea or constipation in premature infants, who are more susceptible to gastrointestinal problems such as necrotizing enterocolitis or feeding intolerance.

Choice C Reason: Volume of urine output. This is an incorrect answer that indicates a valid parameter to assess hydration status. Volume of urine output is a measure of the amount of urine produced and excreted by the kidneys that can reﬂect changes in ﬂuid balance and renal function. Volume of urine output can help monitor hydration status and kidney function in premature infants, who are more vulnerable to ﬂuid overload or deficit and renal impairment.

Choice D Reason: Blood pH. This is because blood pH is a measure of the acidity or alkalinity of the blood, which reﬂects the balance between carbon dioxide and bicarbonate in the body. Blood pH is not a direct indicator of hydration status, which refers to the amount of water and electrolytes in the body. Hydration status can aﬀect blood pH, but blood pH can also be inﬂuenced by other factors such as respiratory or metabolic disorders.

A. Prepare for IV dextrose administration. B. Provide routine care, per hospital IDM protocol. C. Place the infant in a warmed incubator. D. Alert the clinician immediately for orders.

Correct Answer is B

Explanation

Choice A Reason: Prepare for IV dextrose administration. This is an incorrect answer that indicates an unnecessary and invasive intervention for an IDM with normal blood glucose. IV dextrose administration is indicated for an IDM with severe or persistent hypoglycemia, which is defined as a blood glucose below 40 mg/dL or below 60 mg/dL after two feedings.

Choice B Reason: Provide routine care, per hospital IDM protocol. This is because a blood glucose of 60 is within the normal range for an IDM, which is 40 to 80 mg/dL. An IDM is a newborn whose mother has pre-existing or gestational diabetes, which can aﬀect the fetal and neonatal glucose metabolism and regulation. An IDM may have hypoglycemia (low blood glucose), hyperglycemia (high blood glucose), or other complications such as macrosomia, polycythemia, or congenital anomalies. An IDM requires routine care and monitoring according to the hospital IDM protocol, which may include blood glucose testing, feeding, temperature regulation, and observation for signs of distress.

Choice C Reason: Place the infant in a warmed incubator. This is an incorrect answer that suggests an irrelevant and potentially harmful action for an IDM with normal blood glucose. Placing the infant in a warmed incubator is indicated for an IDM with hypothermia, which is a low body temperature that can impair glucose utilization and increase oxygen consumption. However, placing the infant in a warmed incubator without proper indication can cause hyperthermia, which is a high body temperature that can lead to dehydration, electrolyte imbalance, or brain damage.

Choice D Reason: Alert the clinician immediately for orders. This is an incorrect answer that implies an urgent and unwarranted situation for an IDM with normal blood glucose. Alerting the clinician immediately for orders is indicated for an IDM with signs of distress or complications, such as apnea, cyanosis, seizures, or jaundice.
