A client will need serial blood pressure monitoring and frequent blood sampling for ABG's and diagnostic studies. Which of the following vascular devices should the nurse recommend?

Rationale:

A. A small stab wound with a skin blade made into the pleural space is incorrect because creating an open incision is not the standard emergency treatment for a tension pneumothorax. While surgical chest tube placement (thoracostomy) may follow, the immediate life-saving intervention is rapid decompression with a needle. Making a stab wound without proper equipment and sterile technique would be unsafe and inappropriate.

B. Covering the chest wall wound with gauze is incorrect because this intervention is associated with management of an open pneumothorax (“sucking chest wound”), not a tension pneumothorax. In fact, completely sealing a chest wound without allowing air to escape can worsen pressure buildup and potentially create or exacerbate a tension pneumothorax.

C. Immediate tracheostomy is incorrect because a tracheostomy establishes an airway but does not relieve pressure trapped in the pleural space. A tension pneumothorax is a problem of trapped intrapleural air compressing the lung and shifting mediastinal structures—not an upper airway obstruction.

D. Insertion of a 14-gauge needle into the pleural space is correct. A tension pneumothorax occurs when air enters the pleural space and cannot escape, causing progressive pressure buildup. This pressure collapses the affected lung, shifts the mediastinum, compresses the opposite lung, and reduces venous return to the heart, leading to hypotension and potentially cardiac arrest. Immediate needle decompression (needle thoracostomy) using a large-bore needle (commonly 14-gauge) inserted into the pleural space allows trapped air to escape and relieves pressure. This emergency intervention is lifesaving and is followed by chest tube placement for definitive treatment of Tension pneumothorax.

Rationale:

A. Notify the healthcare provider is incorrect as the first action. While the provider must be informed of potential ETT displacement, immediate assessment of the patient’s airway and lung sounds is the priority to ensure safety.

B. Obtain a STAT chest x-ray is incorrect as the first action. A chest x-ray is important for confirming tube placement, but you must first assess for clinical signs of airway compromise or hypoxia before imaging. Waiting for a chest x-ray could delay intervention if the tube has entered a mainstem bronchus.

C. Give the client something for anxiety is incorrect because the anxiety may be a response to hypoxia or airway obstruction, not a primary anxiety issue. Administering medication without assessing the underlying cause could delay critical intervention.

D. Listen to the client's lungs is correct. The first action is to assess breath sounds bilaterally to determine whether the tube has migrated into a mainstem bronchus, which typically causes absent or diminished breath sounds on one side. Immediate assessment of ventilation and oxygenation guides urgent interventions, such as repositioning the ETT, providing oxygen, or calling for help.
