A nurse is caring for four clients on the urology unit. Which of the following data gathered by the nurse leads them to suspect Polycystic Kidney Disease?

A. Severe flank pain, nausea, and vomiting is incorrect because these symptoms are more characteristic of acute kidney stones or obstruction rather than Polycystic Kidney Disease (PKD). While PKD can cause pain, it is usually due to cyst enlargement or infection rather than sudden severe episodes. B. Polyuria, nocturia, sudden colicky pain, and a palpable kidney mass is correct because these are classic findings in PKD. PKD is a genetic disorder characterized by the development of multiple fluid-filled cysts in the kidneys, which can enlarge the kidneys and cause palpable masses. The cysts can interfere with normal urine formation, leading to polyuria (frequent urination) and nocturia (nighttime urination). Colicky pain may occur if cysts rupture or if there is obstruction or infection. C. Urinary urgency, weak urine stream, and dysuria is incorrect because these findings are more typical of lower urinary tract conditions such as urinary tract infections (UTIs) or benign prostatic hyperplasia (BPH), not PKD. D. Periorbital edema, dark frothy urine, and elevated blood pressure is incorrect because these are signs of nephrotic syndrome. Edema and proteinuria (dark frothy urine) result from significant protein loss, which is not the hallmark of PKD.
