A nurse is assessing a client who is receiving a blood transfusion. The nurse notes lung crackles, hypoxia, and distended neck veins. Which of the following actions should the nurse take? (Select all that apply)

Transfusion-associated circulatory overload (TACO) occurs when the infusion rate exceeds the cardiovascular system's capacity, leading to pulmonary edema, impaired gas exchange, and elevated central venous pressure. A. Stopping the transfusion is the immediate priority when any transfusion reaction or complication is suspected. Halting the infusion prevents further volume from entering the intravascular space, which is essential to mitigate the worsening of pulmonary congestion and cardiac strain in a client experiencing circulatory overload. B. Epinephrine is primarily indicated for anaphylactic reactions or cardiac arrest to induce bronchodilation and vasoconstriction. It is not indicated for circulatory overload, as it would increase cardiac workload and potentially exacerbate the hypertensive stress often associated with the fluid volume excess seen in TACO. C. Diuretics, such as furosemide, are a standard treatment for circulatory overload to facilitate the rapid excretion of excess intravascular fluid. Removing surplus fluid helps reduce the preload on the heart, alleviates pulmonary venous pressure, and clears the fluid from the alveolar spaces to improve breathing. D. Administering supplemental oxygen is critical for a client exhibiting hypoxia and lung crackles. Enhancing the fraction of inspired oxygen helps maintain adequate arterial oxygen saturation while the body compensates for the fluid-filled alveoli, ensuring that vital organs receive sufficient oxygenation during the acute respiratory distress. E. Placing the client in a high-Fowler's position promotes maximal chest expansion and uses gravity to shift fluid to the lung bases, thereby improving ventilation-perfusion matching. This position reduces the work of breathing and decreases venous return to the heart, which helps alleviate the symptoms of acute pulmonary edema.
