Final answer:
In cases of respiratory distress where a nebulized bronchodilator is already being administered, additional interventions may include oxygen, CPAP, and systemic corticosteroids, depending on protocols and the child's clinical status.
Step-by-step explanation:
A 7 year old male with respiratory distress who is already receiving a nebulized bronchodilator may benefit from additional supportive therapies prior to contacting medical command. These therapies can include the administration of oxygen to improve oxygen saturation and relieve hypoxia, application of nasal continuous positive airway pressure (CPAP) if he is having significant difficulty in breathing, or in severe cases, the use of systemic corticosteroids to reduce inflammation. However, the actual decision to administer these interventions would typically depend on the treating emergency personnel's protocols and the specific clinical situation of the child. Each of these interventions aims to support the child's breathing and manage the underlying causes of the respiratory distress until further medical care can be provided.
