A nurse is admitting a new client to the hospital. The echocardiogram report revealed left ventricular enlargement. The nurse notes 2+ pitting edema in the ankles when getting the client into bed. Based on this finding, what should the nurse do first?

Choice A reason: Drawing blood for lab studies, such as BNP or electrolytes, is important in heart failure to assess severity and guide treatment. However, 2+ pitting edema and left ventricular enlargement suggest acute pulmonary congestion, making respiratory assessment the priority to detect life-threatening complications like pulmonary edema. Choice B reason: Weighing the client monitors fluid status in heart failure, as weight gain indicates fluid retention. While important, it is secondary to assessing respiratory status, as edema and ventricular enlargement suggest possible pulmonary edema, which poses an immediate threat to oxygenation. Choice C reason: Left ventricular enlargement and 2+ pitting edema indicate left-sided heart failure, which can lead to pulmonary edema, causing dyspnea and hypoxia. Assessing respiratory status first ensures detection of crackles or respiratory distress, enabling prompt intervention to prevent respiratory failure or worsening heart failure. Choice D reason: Inserting a Foley catheter monitors urine output in heart failure but is not the first action. Respiratory distress from pulmonary edema, suggested by edema and ventricular enlargement, is a more immediate concern, requiring assessment of breathing to ensure adequate oxygenation and safety.
