During the Oliguric phase of acute kidney injury, which of the following symptoms would you expect in a patient with fluid overload?
Explanation & Rationale
A. Distended neck veins is correct because during the oliguric phase of AKI, the kidneys are unable to excrete adequate amounts of fluid. This leads to volume overload, which increases central venous pressure. One of the most visible signs of this is jugular venous distension (JVD), indicating that the heart is under increased preload stress due to retained fluid. This can also be an early indicator of potential complications such as pulmonary congestion or heart failure. B. Hypotension is incorrect because fluid overload usually results in hypertension, not hypotension. Blood pressure rises as the circulating volume increases, which can further compromise kidney function and exacerbate cardiac stress. Hypotension is more characteristic of pre-renal AKI, which is often caused by hypovolemia or decreased perfusion to the kidneys. C. Edema is correct because impaired renal excretion during the oliguric phase causes fluid retention, leading to accumulation in the interstitial spaces. This is commonly observed as peripheral edema in the legs and feet, sacral edema in bedridden patients, and in severe cases, pulmonary edema, which can present with dyspnea and crackles on auscultation. Edema is a hallmark clinical finding in patients with AKI and fluid overload. D. Fever is incorrect because it is not a direct symptom of fluid overload. While fever may occur if there is a concurrent infection (which can contribute to AKI), it is not a defining characteristic of the oliguric phase.
