The nurse plans care for a client with lymphoma presenting with facial and neck swelling, a cough, and shortness of breath. Which interventions should the nurse include in the client's care? Select all that apply

Rationale: A. Pericardiocentesis is indicated for pericardial effusion or cardiac tamponade, not for superior vena cava (SVC) syndrome caused by lymphoma. Facial and neck swelling with respiratory symptoms in lymphoma typically indicates SVC obstruction. B. Swelling in the face, neck, and upper extremities can worsen with constriction from rings, necklaces, or tight clothing. Removing jewelry helps prevent circulation compromise and discomfort. C. In severe or refractory SVC syndrome, endovascular stenting can relieve obstruction caused by a tumor compressing the superior vena cava. Preparing for stent placement is appropriate if prescribed. D. Tolvaptan is a vasopressin receptor antagonist used to treat hyponatremia or fluid overload in heart failure, not SVC syndrome. It does not relieve vascular obstruction from lymphoma. E. Elevating the head reduces venous pressure in the upper body, improving breathing and relieving edema in the face and neck. This is a noninvasive supportive intervention for SVC syndrome.
