A newborn is admitted to the NICU with suspected meconium aspiration syndrome (MAS). The infant is experiencing respiratory distress with grunting, nasal flaring, and cyanosis. What is the nurse's highest priority intervention?
1Administer supplemental oxygen via nasal cannula
2Position the infant in Trendelenburg position to facilitate drainage
3Perform chest physiotherapy to mobilize secretions
4Prepare for endotracheal intubation and mechanical ventilation✓ 정답
해설
Severe respiratory distress with grunting, nasal flaring, and cyanosis in MAS indicates life-threatening airway obstruction requiring immediate endotracheal intubation and mechanical ventilation. Other options (oxygen, positioning, chest physiotherapy) are insufficient for severe cases.
Clinical Judgment
This question assesses clinical priority setting. The patient is exhibiting severe respiratory distress due to Meconium Aspiration Syndrome (MAS). The key clues are "grunting, nasal flaring, and cyanosis". These are signs of acute respiratory failure that cannot be resolved with simple oxygen supplementation, requiring you to Notify HCP!. Therefore, the nurse's top priority intervention is to prepare for a higher level of airway management and respiratory support.
Memory Tip: Remember MAS-I: Meconium blocks the Airway, and Severe distress requires Intubation.
KR vs US: In Korea, initial management for a MAS patient might involve immediate suctioning along with oxygen supplementation and conservative care. However, in the NGN/US approach, severe respiratory distress accompanied by cyanosis is considered an absolute indication requiring immediate action to prepare for mechanical ventilation.
Clinical Practice GuideThe focus of MAS management is securing the airway, adequate ventilation, and correcting hypoxia and acidosis. For a lethargic newborn born in thick meconium-stained amniotic fluid, oropharyngeal and nasopharyngeal suctioning immediately after birth is standard. However, if progressive respiratory distress develops after admission to the NICU, mechanical ventilation along with suctioning through an endotracheal tube is very likely needed.
Caution: Options 1, 2, and 3 are all interventions that can be used in MAS management, but they are not the highest priority intervention for a patient with "cyanosis." In SATA (Select All That Apply) questions, these interventions may all be included in the list of correct answers, but in a single-choice "highest priority" question, airway securing and life-sustaining respiratory support always come first.
Meconium Aspiration Syndrome — Neonatal respiratory distress syndrome caused by the fetus inhaling amniotic fluid contaminated with meconium. Can lead to airway obstruction, chemical pneumonia, and pulmonary hypertension.
Cyanosis — Bluish discoloration of the skin or mucous membranes, a severe sign indicating low oxygen saturation in the blood.
Endotracheal Intubation — A procedure that involves inserting a tube into the trachea to secure the airway and provide mechanical ventilation.
Respiratory Distress — Dyspnea. It presents with signs such as tachypnea, nasal flaring, intercostal retractions, grunting, and cyanosis.
Meconium — Newborn's first stool. It consists of mucus, bile, and fetal intestinal cells, and is sterile. Its presence in amniotic fluid may be a sign of fetal distress.
