A nurse is assessing a client who has asthma and signs of central cyanosis. Which of the following is a reliable indicator of cyanosis?

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. Auscultate breath sounds at least every 2 hours.

Regularly auscultating breath sounds is important for assessing respiratory status and detecting any signs of respiratory complications such as pneumonia or atelectasis. However, it is not the priority action in this scenario compared to applying antiembolic stockings, which directly addresses the increased risk of DVT and PE associated with immobility.

B. Perform range-of-motion exercises at least two to three times daily.

Range-of-motion exercises help prevent contractures and maintain joint mobility in immobile clients. While they are important for preventing musculoskeletal complications, they are not the priority action compared to applying antiembolic stockings, which directly addresses the increased risk of DVT and PE associated with immobility.

C. Make sure the client has an intake of 2,000 to 3,000 mL of fluid per day.

Maintaining adequate hydration is important for overall health and prevention of complications such as urinary tract infections and constipation. However, it is not the priority action in this scenario compared to applying antiembolic stockings, which directly addresses the increased risk of DVT and PE associated with immobility.

D. Apply antiembolic stockings.

The priority action for the nurse to contribute to the plan of care for an immobile client is to apply antiembolic stockings. Immobility increases the risk of deep vein thrombosis (DVT) and subsequent pulmonary embolism (PE). Antiembolic stockings (also known as compression stockings or TED stockings) help prevent venous stasis and decrease the risk of blood clots forming in the lower extremities. Therefore, applying antiembolic stockings is essential in mitigating the risk of potentially life-threatening complications associated with immobility.
