Answer :
Final answer:
The symptoms described suggest an inadequate supply of oxygen to the body due to a possible decrease in alveolar ventilation. Stopping the suctioning and investigating other causes would be the most appropriate action. Option a
Explanation:
The symptoms described, including decreased O₂ levels, decreased blood pressure, coughing, and dysrhythmias, suggest an inadequate supply of oxygen to the body. One of the possible causes for these symptoms could be a decrease in alveolar ventilation, which refers to the movement of air in and out of the alveoli in the lungs. When ventilation is not sufficient, the capillaries that are responsible for exchanging oxygen and carbon dioxide with the alveoli may constrict, resulting in decreased oxygen levels and decreased blood pressure. This could also lead to coughing due to the body's attempt to clear the airways and dysrhythmias due to insufficient oxygen supply to the heart.
In this scenario, it would be important to address the issue causing the inadequate alveolar ventilation. If suctioning was being done and the symptoms worsened, it may be necessary to stop the suctioning and assess for other potential causes. Changing the suction catheter or increasing the suction pressure may not be necessary or effective if the root cause of the symptoms lies in the ventilation of the alveoli. Therefore, the most appropriate action would be to stop the suctioning and investigate other possible reasons for the decreased alveolar ventilation.
