Q1In a neonate diagnosed with respiratory distress syndrome (RDS), which of the following conditions would contribute to a decrease in surfactant production?
Show answer
✓ Correct answer: Premature birth
Answer: Premature birth. In neonates, particularly those born prematurely, there is often a deficiency in surfactant production due to immature lungs. Surfactant reduces surface tension in the lungs and is crucial for keeping the alveoli open. Increased oxygen levels and decreased $$CO_{2}$$ levels do not directly reduce surfactant production. Term birth typically indicates adequate surfactant levels.
Q2For newborns experiencing transient tachypnea (TTN), what do grunting, nasal flaring, and chest retractions signify?
Show answer
✓ Correct answer: An attempt to maintain adequate lung expansion
Answer: An attempt to maintain adequate lung expansion For newborns with TTN, the fluid in the lungs can lead to difficulty in breathing, resulting in reduced lung expansion. Grunting and nasal flaring are mechanisms to create positive end-expiratory pressure (PEEP) to keep alveoli open, while chest retractions indicate the effort needed to breathe effectively. Energy conservation is critical for sick newborns and is often shown by decreased activity. Upper airway resistance is due to nasal or pharyngeal structural factors, and airway obstruction is typically due to mucus or congenital issues, which are not alleviated by grunting or retracting.
Q3Which of the following treatments is recommended for neonates with Respiratory Distress Syndrome (RDS) to improve lung function?
Show answer
✓ Correct answer: Exogenous Surfactant Therapy
Answer: Exogenous Surfactant Therapy Surfactant is a substance that helps keep the air sacs in the lungs open. It's often deficient in premature infants with RDS. Administering exogenous surfactant improves lung function and reduces the risk of complications and mortality in these infants. Surfactant therapy should be administered early and infants should be continuously monitored for improvements in oxygenation and respiratory effort.
Q4A nurse is caring for an infant receiving continuous positive airway pressure (CPAP) therapy and observes signs of nasal flaring and retractions. Which of the following is an appropriate nursing action?
Show answer
✓ Correct answer: Provide non-nutritive sucking with sucrose and swaddling during the adjustment of the CPAP interface
Answer: Provide non-nutritive sucking with sucrose and swaddling during the adjustment of the CPAP interface Comfort measures (e.g., non-nutritive sucking, expressed breast milk, sucrose, and swaddling) are recommended during CPAP interface adjustments to provide pain relief and reduce stress responses. Increasing the CPAP pressure without consulting the physician can cause potential harm and is not recommended. Mucus is not miscible with saline solution, so a bolus of saline will not help in this situation. Additionally, bolus saline has no role in adjusting CPAP settings. Turning the infant's head during CPAP adjustment is not advised, as it could occlude the jugular vein, increase intracranial pressure, and pose other risks.
Q5Which gas is most commonly administered to newborns in respiratory distress?
Show answer
✓ Correct answer: Oxygen
Answer: Oxygen Oxygen is most commonly administered to newborns experiencing respiratory distress to ensure they receive adequate oxygenation. Similarly to other drugs, it must be treated with caution and given only for specific indications. These include biochemical criteria (e.g., $$PaO_{2}$$ below 60 mm Hg) and clinical criteria such as respiratory distress, central cyanosis, apnea, asphyxia, hypotonia, and low oxygen saturations. While gases like helium, nitrous oxide, and carbon dioxide can have medical uses, they are not commonly used for respiratory distress in newborns.
Q6While administering indomethacin to a newborn with patent ductus arteriosus, the nurse should closely monitor for which electrolyte imbalance?
Show answer
✓ Correct answer: Hyponatremia
Answer: Hyponatremia Indomethacin can cause hyponatremia due to its effect on kidney function. It leads to increased sodium and water excretion, resulting in a decrease in serum sodium levels. Indomethacin is often used to close a patent ductus arteriosus and should be used cautiously, especially in newborns with renal impairment.
