Final answer:
Before contacting medical command, supplemental oxygen and monitoring vital signs are appropriate interventions for a patient with respiratory distress on nebulized bronchodilator therapy and CPAP.
Step-by-step explanation:
A 67-year-old female with respiratory distress is receiving a nebulized bronchodilator and has been placed on CPAP. In such a medical scenario, where the patient is already receiving bronchodilation therapy and CPAP, other supportive treatments before contacting medical command may include administering supplemental oxygen, if not contraindicated, and ensuring that the patient is in a comfortable position to facilitate easier breathing. This could be complemented by monitoring vital signs closely to assess the patient's response to therapy. It's important to note that any additional interventions would depend on the patient's specific condition, the protocols established by the medical service, and the clinical judgment of the healthcare professional.
