During a field assessment, what is the indicator of a successful intervention for a patient in respiratory distress?

The correct choice highlights vital physiological responses that signify improvement in a patient experiencing respiratory distress. Improved breath sounds indicate that air is moving more effectively through the airways, suggesting that any obstruction has relieved or that lung function is returning to normal. The return of normal saturation of peripheral oxygen (SpO2) levels reflects adequate oxygenation of the blood, which is crucial for patient stabilization. This dual assessment of breath sounds and oxygen saturation provides a concrete indication that the interventions applied, such as administering supplemental oxygen or bronchodilators, are having the desired effect on the patient’s respiratory status.

The other indicators present in the options may reflect different responses to treatment but do not directly correlate with the successful resolution of respiratory distress. For instance, decreased heart rate and increased blood pressure could indicate a range of physiological responses and do not specifically pertain to the effectiveness of respiratory interventions. Similarly, while a patient verbalizing relief and stability is a positive sign, it is subjective and may not correlate with measurable physiological improvements. Diminished lung sounds and increased anxiety are concerning signs that flag worsening respiratory function and patient distress, respectively, rather than improvements. Thus, the most definitive indicators of successful intervention in this context are the physical findings of breath sounds and SpO2 levels
