RN Nursing · Chronic Kidney Disease · Practice question
An NP is assessing a patient with a history of chronic kidney disease (CKD). Which of the following examination findings indicates the need for rapid evaluation and possible dialysis?
-
Conjunctival pallor.
-
✓
Pericardial rub.
-
Generalized pruritus.
-
Weight loss.
Answer & explanation
Correct: Pericardial rub.
In a patient with chronic kidney disease, the development of a pericardial rub on auscultation signals uremic pericarditis, which is a serious complication indicating that uremic toxins have accumulated to a level that is causing pericardial inflammation. Uremic pericarditis is an indication for urgent initiation of dialysis because it reflects severe, life-threatening uremia that medical management alone cannot adequately address. Left untreated, it can progress to cardiac tamponade, which can be fatal. Conjunctival pallor is a common finding in CKD reflecting the normochromic, normocytic anemia caused by decreased erythropoietin production. While anemia requires management, it does not by itself mandate emergency dialysis. Generalized pruritus is another very common manifestation of CKD due to uremic toxin deposition in the skin and altered calcium-phosphate metabolism; it is uncomfortable but does not independently trigger urgent dialysis initiation. Weight loss can occur in CKD due to anorexia, protein-energy wasting, and dietary restrictions, but it is a general finding that does not specifically signal the need for immediate dialysis. The key clinical teaching point is that uremic pericarditis — evidenced by a pericardial friction rub — represents an absolute indication for dialysis in CKD because it indicates a critical level of uremia that poses immediate risk to life.
