A nurse is reviewing the laboratory results of a client who is postoperative and has a respiratory rate of 7/min. The arterial blood gas (ABG) values include: pH 7.22 PaCO2 68 mm Hg Base excess -2 PaO2 78 mm Hg Oxygen saturation 80% Bicarbonate 28 mEq/L. Which of the following interpretations of the ABG values should the nurse make?

A. Prepare the client for endotracheal suctioning.

Endotracheal suctioning is a procedure used to clear secretions from the airway, which may be necessary in cases of respiratory distress. However, it is not the first action to take in this scenario. Before proceeding with suctioning, the nurse should first assess the client's respiratory status and implement interventions to improve ventilation and oxygenation.

B. Elevate the head of the bed.

This is the correct action to take first. Elevating the head of the bed helps improve the client's respiratory mechanics by allowing better lung expansion and reducing the work of breathing. It also helps alleviate symptoms of respiratory distress. This intervention should be implemented immediately to optimize the client's breathing.

C. Request a chest x-ray.

While a chest x-ray may provide valuable information about the client's respiratory status, it is not the first action to take in this acute situation. Chest x-rays require time to be performed and interpreted, which may delay necessary interventions to address the client's immediate respiratory distress.

D. Obtain a sputum culture.

Obtaining a sputum culture may be indicated to identify the underlying cause of respiratory distress, such as infection. However, it is not the first action to take when the client is experiencing acute respiratory distress. The priority is to implement interventions to improve ventilation and oxygenation to stabilize the client's condition.

A. Add tap water as needed to the suction control chamber.

This is not the correct action. The suction control chamber of a water-seal chest tube drainage system is typically filled with sterile water to the prescribed level by the healthcare provider during the initial setup. Adding tap water to the suction control chamber can disrupt the balance of the system and affect the prescribed suction level. The nurse should not add tap water without specific instructions from the healthcare provider.

B. Maintain the drainage container below the level of the client's chest.

This is the correct action. In a water-seal chest tube drainage system, it's important to keep the drainage container below the level of the client's chest. This positioning allows gravity to assist in the drainage of air or fluid from the pleural space into the drainage container. It also helps prevent backflow of fluid or air into the chest cavity, ensuring the effectiveness of the drainage system.

C. Empty the collection container every shift.

While it may be necessary to empty the collection container if it becomes full, emptying it every shift is not a set rule. The frequency of emptying the collection container should be based on the volume of drainage and the facility's policy. The nurse should monitor the collection container regularly and empty it when it reaches the appropriate level, typically around half full or as indicated by facility protocol.

D. Clamp the chest tubes if it becomes disconnected.

Clamping the chest tubes if they become disconnected is not recommended. It can lead to tension pneumothorax, a life-threatening condition where air accumulates in the pleural space and compresses the lung. If a chest tube becomes disconnected, the nurse should immediately assess the situation, secure the chest tube connections, and notify the healthcare provider for further management.
