A nurse is monitoring a client following a thoracentesis. The nurse should identify which of the following manifestations as a complication and contact the provider immediately?

A. Encourage oral intake of at least 3,000 mL of fluids per day:
This is not a priority intervention for ARDS. While maintaining adequate hydration is important, the primary focus in ARDS is on respiratory support and oxygenation. Excessive fluid intake may exacerbate pulmonary edema in these patients.

B. Offer high-protein and high-carbohydrate foods frequently:
Nutritional support is important in ARDS, but the primary concern is oxygenation and respiratory function. Offering high-protein and high-carbohydrate foods can support the client's overall nutritional needs, but it may not directly address the respiratory distress.

C. Administer low-flow oxygen continuously via nasal cannula:
This is not typically sufficient for ARDS. ARDS often requires higher levels of oxygen support, and low-flow oxygen may not meet the increased oxygen demand. More aggressive oxygenation strategies, such as non-invasive positive pressure ventilation (NIPPV) or mechanical ventilation, may be necessary.

D. Place in a prone position:
Placing the patient in a prone position is a recommended intervention for ARDS. Prone positioning can improve oxygenation by optimizing ventilation-perfusion matching and reducing pressure on the lungs. This intervention is aimed at improving respiratory function in ARDS patients.

A. Elevate the client’s head of bed:
Elevating the head of the bed is a good practice for patients on mechanical ventilation as it helps prevent complications such as aspiration. However, in the scenario where the client has pulled out the endotracheal tube, the immediate concern is assessing the airway and ensuring adequate oxygenation and ventilation. Elevating the head of the bed can be done later as needed.

B. Assess the client’s airway:
This is the correct and priority action. The nurse should assess the client's airway first to determine the extent of the situation. This involves checking for signs of airway obstruction, respiratory distress, or inadequate oxygenation. The assessment guides subsequent interventions.

C. Prepare the client for intubation:
While preparing for intubation may be necessary if the endotracheal tube is completely displaced, assessing the airway comes first. The nurse needs to gather information about the client's current condition before deciding on the appropriate course of action.

D. Suction the client’s mouth:
Suctioning may be necessary, especially if there are secretions or other obstructions in the mouth or airway. However, it should come after the initial assessment of the airway. If the client's airway is clear, suctioning may not be the immediate priority.
