The nurse is planning to teach infant care and preventive measures for sudden infant death syndrome (SIDS) to a group of new parents. Which information is most important for the nurse to include?

Choice A reason: Marking an outline of the "olive-shaped" mass in the right epigastric area is not a priority nursing action. The mass is caused by hypertrophy of the pyloric sphincter, which obstructs gastric emptying and causes projectile vomiting. The mass may not be palpable in all cases.

Choice B reason: Instructing parents regarding care of the incisional area is a post-operative nursing action, not a pre-operative one. The parents will need to learn how to keep the incision clean and dry, monitor for signs of infection, and administer pain medication as prescribed.

Choice C reason: Monitoring amount of intake and infant's response to feedings is important, but not the highest priority. The infant may have difficulty feeding due to nausea, vomiting, and abdominal pain.

Choice A reason: Scheduling the child for a STAT magnetic resonance imaging (MRI) of the neck is not a priority action for the nurse. MRI is a diagnostic test that uses magnetic fields and radio waves to produce images of the internal structures of the body. MRI of the neck may be useful to rule out other causes of respiratory distress, such as tumors, abscesses, or foreign bodies, but it is not an urgent procedure. Moreover, MRI requires the child to lie still for a long time, which may be difficult or impossible for a child who is anxious and in respiratory distress.

Choice B reason: Providing a nebulizer treatment with bronchodilators is not a suitable action for the nurse. Nebulizer is a device that delivers medication in the form of a mist that can be inhaled into the lungs. Bronchodilators are medications that relax the smooth muscles of the airways and improve airflow. Nebulizer treatment with bronchodilators may be helpful for children with respiratory distress caused by asthma, bronchiolitis, or chronic obstructive pulmonary disease, but not for children with respiratory distress caused by upper airway obstruction, which is the most likely scenario for this child.

Choice C reason: Obtaining bedside trays for intubation or tracheotomy by the healthcare provider is the most appropriate action for the nurse. Intubation is a procedure that involves inserting a tube through the mouth or nose into the trachea to secure the airway and provide ventilation. Tracheotomy is a surgical procedure that involves creating an opening in the neck and inserting a tube into the trachea to bypass the upper airway obstruction. Both procedures are life-saving interventions for children with respiratory distress caused by upper airway obstruction, which is the most likely scenario for this child. The nurse should prepare the necessary equipment and assist the healthcare provider in performing these procedures.

Choice D reason: Beginning prescribed intravenous antibiotic administration is not a relevant action for the nurse. Antibiotics are medications that kill or inhibit the growth of bacteria that cause infections. Antibiotics may be indicated for children with respiratory distress caused by bacterial infections, such as pneumonia, tonsillitis, or epiglottitis, but not for children with respiratory distress caused by non-infectious causes, such as foreign bodies, anaphylaxis, or congenital anomalies. Moreover, antibiotics are not an immediate intervention for respiratory distress, as they take time to exert their effects.
