Final answer:
A sudden decrease in oxygen saturation level would warrant immediate intervention in a patient with progressive kyphoscoliosis leading to respiratory distress.
Step-by-step explanation:
When a patient with muscular dystrophy presents with progressive kyphoscoliosis leading to respiratory distress, there are many potential findings that would warrant immediate intervention by the nurse. However, one finding that would specifically require immediate attention is a sudden decrease in oxygen saturation level.
In a patient with respiratory distress, a decrease in oxygen saturation indicates that they are not getting enough oxygen, which can be life-threatening. Immediate intervention could include administering supplemental oxygen, assessing for respiratory distress severity.
Notifying the healthcare provider for further intervention. Other potential findings that would require immediate intervention include sudden difficulty breathing, cyanosis (blue discoloration of the skin), or a decrease in respiratory effort.
