Which laboratory results should the nurse closely monitor in a client who has end-stage renal disease (ESRD)?

A. Serum potassium, calcium, and phosphorus: Correct! In end-stage renal disease (ESRD), the kidneys are unable to adequately filter waste products and maintain electrolyte balance. Monitoring serum potassium, calcium, and phosphorus levels is crucial as imbalances in these electrolytes are common and can lead to serious complications such as cardiac arrhythmias, bone disorders, and muscle weakness. B. Erythrocytes, hemoglobin, and hematocrit: While anemia is a common complication of ESRD, monitoring erythrocyte indices (such as erythrocyte count, hemoglobin, and hematocrit) is important, but it is not specifically related to renal function monitoring. C. Leukocytes, neutrophils, and thyroxine: Monitoring leukocytes and neutrophils is important for assessing immune function and detecting infections, but it is not directly related to renal function monitoring in ESRD Thyroxine monitoring is relevant for thyroid function, which is not typically affected by ESRD. D. Blood pressure, heart rate, and temperature: Monitoring vital signs such as blood pressure, heart rate, and temperature is important in overall client assessment, but it does not specifically address the need for monitoring electrolyte imbalances associated with ESRD These parameters may be affected by complications of ESRD, but the primary focus in ESRD monitoring is on renal function and electrolyte balance.
