A patient has a diagnosis of Impaired Gas Exchange. Which assessment finding shows that the interventions have been effective?
A.
The patient’s Spo2 is 97% on 2L NC
B.
The patient appears comfortable
C.
The patient is coughing up copious white sputum
D.
The patient is able to move out of bed without difficulty
The correct answer and Explanation is :
The correct answer is A. The patient’s SpO2 is 97% on 2L NC.
Explanation:
Impaired gas exchange refers to the inadequate exchange of oxygen and carbon dioxide in the lungs, leading to hypoxemia (low blood oxygen levels) and potential respiratory distress. When assessing the effectiveness of interventions for a patient with this diagnosis, the primary goal is to improve oxygenation and ensure adequate gas exchange.
Option A: A SpO2 of 97% on 2L NC (nasal cannula) indicates that the patient is achieving a nearly normal level of oxygen saturation. This is a key indicator of improved gas exchange, as normal SpO2 levels typically range from 95% to 100%. Maintaining a SpO2 of 97% suggests that the interventions—such as supplemental oxygen therapy—are successfully supporting the patient’s respiratory needs.
Option B: While the patient appearing comfortable is a positive sign, it is subjective and does not provide a direct measure of gas exchange. Comfort can be influenced by various factors, and it does not necessarily correlate with effective oxygenation.
Option C: Coughing up copious white sputum could indicate underlying issues such as infection or congestion, which may complicate gas exchange rather than signify improvement. This finding requires further evaluation rather than being an indicator of successful intervention.
Option D: The ability to move out of bed without difficulty suggests improved functional mobility, which is important for overall recovery. However, it does not directly address the effectiveness of interventions aimed at enhancing gas exchange.
In conclusion, the primary assessment finding indicating successful intervention for impaired gas exchange is the measurement of SpO2, making Option A the best choice. Monitoring oxygen saturation provides objective data to assess the patient’s respiratory status and the effectiveness of therapeutic interventions.
