A nurse is caring for a client at risk for atelectasis. Which independent nursing measure should the nurse prioritize to prevent atelectasis development?

Pulmonary Function Tests assess chronic respiratory conditions like COPD and asthma. In an acute pneumothorax, these tests are unnecessary as the priority is stabilizing the airway and restoring lung expansion. The client is in respiratory distress, making PFTs impractical and irrelevant at this stage.

Obtain Intravenous Access: IV access is necessary to administer fluids, medications, and potential emergency interventions. Given the client's signs of respiratory distress and hemodynamic instability (tachycardia, hypotension), IV access ensures rapid treatment in case of deterioration.

Thoracentesis: Thoracentesis is used to remove pleural fluid in conditions like pleural effusion but is not appropriate for a pneumothorax. Inserting a needle into the pleural space could worsen the lung collapse and lead to further respiratory compromise. The correct intervention is a chest tube insertion.

Obtain ABGs: ABGs provide critical information on oxygenation, ventilation, and acid-base balance. The client has tachypnea, cyanosis, and low O₂ saturation, indicating possible respiratory acidosis or hypoxemia. ABGs will guide oxygen therapy and further management.

Prepare for Insertion of a Chest Tube: A chest tube is the definitive treatment for a pneumothorax. It removes air from the pleural space, allowing lung re-expansion. Given the client's absent breath sounds, tachypnea, and hypoxia, immediate chest tube insertion is necessary to prevent further deterioration.

Computed Tomography (CT) of the Chest: While a CT scan provides detailed lung imaging, it is not the first-line diagnostic tool for pneumothorax. A chest X-ray is usually sufficient to confirm the diagnosis. In an emergency setting, immediate intervention (such as chest tube placement) takes priority over advanced imaging.

A. Auscultate lungs for the presence of breath sounds: This is the priority action following endotracheal intubation, as it directly assesses the effectiveness of the intubation. Auscultating the lungs allows the nurse to confirm that the endotracheal tube is properly positioned in the trachea and that air is reaching the lungs. Abnormal breath sounds, such as decreased or absent sounds on one side, may indicate improper placement or complications like a pneumothorax, making this assessment critical for patient safety.
B. Assess baseline level of consciousness: While assessing the client's level of consciousness is important for evaluating their overall neurological status, it is not the immediate priority following intubation. Changes in consciousness can be influenced by various factors, including sedation or hypoxia, but ensuring proper airway placement and ventilation is more urgent to prevent respiratory compromise.
C. Assess for the presence of circumoral cyanosis: Circumoral cyanosis can indicate inadequate oxygenation, but it may not be immediately apparent after intubation. This assessment is important, but it is secondary to confirming that breath sounds are present and that the airway is secure. Identifying airway placement issues is more crucial before evaluating for signs of hypoxia.
D. Determine that the pulse oximetry is greater than 95%: Monitoring pulse oximetry is essential for assessing oxygen saturation and identifying potential hypoxia. However, if the endotracheal tube is not properly placed, the pulse oximetry may not accurately reflect the client’s respiratory status. Therefore, ensuring proper ventilation through auscultation of breath sounds takes precedence over solely relying on pulse oximetry readings.
