In a patient with chronic kidney disease on strict fluid restriction, which assessment finding requires additional nursing action?

• A. Elevated blood pressure
• B. Dry mucous membranes
• C. Diminished breath sounds
• D. Crackles

Answer: (D)

Fluid balance in chronic kidney disease is tightly monitored because excess fluid can accumulate in the lungs, leading to pulmonary edema. Crackles on auscultation reflect fluid in the alveoli and indicate that the patient is experiencing pulmonary edema despite fluid restriction. This finding signals a need for immediate nursing action: reassess respiratory status, monitor oxygen saturation, check vital signs, review intake and output and daily weights, and communicate with the provider about potential adjustments to fluid management or meds. Positioning the patient to ease breathing and providing supplemental oxygen if needed are appropriate interim measures. Dry mucous membranes suggest dehydration rather than overload, and diminished breath sounds are not as specific for fluid in the lungs as crackles, so they don’t point to the same urgent need for intervention.
