The nurse is caring for a patient with congestive heart failure who has bilateral ankle edema, jugular vein distention, and a weight gain of 3 pounds in the past 24 hours. What is the nurse's priority action?

Choice A rationale Teaching the patient about fluid restriction is a critical component of long-term chronic disease management for heart failure to prevent future exacerbations. However, education is a lower priority during an acute phase of fluid volume excess. When a patient presents with physical symptoms like a significant 3-pound weight gain and peripheral edema, the nurse must prioritize physiological stabilization and pharmacological intervention over teaching, as the patient may be too distressed to effectively learn or retain information. Choice B rationale A thorough respiratory assessment is vital to check for pulmonary edema, often manifested by crackles or decreased oxygen saturation, which frequently accompanies right-sided heart failure progression. While assessment is a key nursing step, the symptoms provided already confirm significant systemic fluid overload. After identifying the problem through these initial findings, the nurse should move to the intervention that will directly resolve the fluid excess and prevent the patient from progressing into acute respiratory distress or failure. Choice C rationale Encouraging sodium restriction is a necessary dietary modification because sodium promotes water retention through osmotic pressure, worsening the workload on a failing heart. Like fluid restriction education, this is a secondary prevention strategy meant for long-term maintenance. In the presence of acute jugular vein distention and rapid weight gain, dietary changes will not work fast enough to relieve the current pressure on the cardiovascular system or reduce the extracellular fluid volume effectively. Choice D rationale Administering a prescribed diuretic, such as furosemide, is the priority because it directly addresses the fluid volume excess by promoting the excretion of sodium and water by the kidneys. This pharmacological intervention reduces the preload and systemic venous pressure, thereby alleviating the jugular vein distention and ankle edema. Rapid diuresis is necessary to prevent the fluid from backing up further into the pulmonary circulation, which could lead to life-threatening pulmonary edema and impaired gas exchange.
