A nurse is caring for a 35-year-old patient with Hodgkin lymphoma who reports progressive swelling in the neck and arms, along with difficulty swallowing and hoarseness. The patient's blood pressure is 100/70 mmHg, heart rate is 100 bpm, and oxygen saturation is 92% on room air. What is the nurse's priority action?

The patient presents with severe shortness of breath, chest pain, facial swelling, hypotension, and hypoxia, consistent with superior vena cava syndrome (SVCS). The priority action is to elevate the head of the bed and administer high-flow oxygen to improve venous drainage and oxygenation, addressing the immediate life-threatening symptoms.

Clinical Presentation Analysis

The patient exhibits classic signs of superior vena cava syndrome (SVCS), an oncologic emergency. Progressive swelling in the neck and arms, dysphagia (difficulty swallowing), and hoarseness result from impaired venous return from the head, neck, and upper extremities due to external compression or internal obstruction of the superior vena cava (SVC). In a patient with Hodgkin lymphoma, a mediastinal mass is the most common cause of this compression. The vital signs—blood pressure 100/70 mmHg, heart rate 100 bpm (tachycardia), and oxygen saturation 92% on room air—indicate developing hemodynamic instability and respiratory compromise. The tachycardia and borderline hypotension suggest decreased venous return to the heart, while the low oxygen saturation reflects potential airway edema or compression, or an associated pleural or pericardial effusion, which are known complications of anterior mediastinal masses ^[3].

Priority Action Rationale

The nurse's priority is to maintain the airway and optimize respiratory function while reducing venous congestion. Elevating the head of the bed uses gravity to decrease hydrostatic pressure in the upper body, which can temporarily reduce cerebral and laryngeal edema, thereby alleviating dyspnea and the sensation of choking. Administering high-flow oxygen is critical to correct the hypoxemia (SpO2 92%) caused by compromised gas exchange. This intervention directly addresses the immediate life-threats of airway compromise and severe hypoxemia.

Analysis of Incorrect Options

Option 1 (Administer prescribed morphine): While the patient may have chest discomfort from the mass effect, morphine is a respiratory depressant. In a patient with a compromised airway and already low oxygen saturation, this action could precipitate respiratory arrest. Pain management is secondary to airway and breathing stabilization.

Option 2 (Place in Trendelenburg position): This position is contraindicated in SVCS. Placing the head lower than the heart would dramatically increase venous pressure in the already-obstructed upper body, worsening cerebral edema, laryngeal swelling, and the risk of airway obstruction. The goal is to facilitate venous drainage from the head, not impede it.

Option 4 (Prepare for immediate chest tube insertion): A chest tube is indicated for pneumothorax or large pleural effusions causing tension physiology. The patient's primary problem is SVC compression from a mediastinal mass, which is not directly treated with a chest tube. While a chylothorax can be a rare presentation of SVC thrombosis , the immediate nursing priority remains respiratory and hemodynamic support, not an invasive procedure that does not address the underlying SVC obstruction. Furthermore, interventions involving anesthesia or positive pressure ventilation in a patient with an anterior mediastinal mass carry a high risk of cardiovascular collapse due to loss of compensatory sympathetic tone and further compression of the heart and great vessels ^[3].
