An older client is hospitalized with suspected heart failure. After 2 days of treatment, the client is not improving. Which laboratory value does the nurse report to the provider?

a. Potassium, 3.7 mEq/L
b. Sodium, 144 mEq/L
c. Glomerular filtration rate, 55 mL/min
d. Creatinine, 0.9 mg/dL


C
The client's GFR is extremely low; this can correspond with kidney disorders, including acute glomerulonephritis (GN). Because of pulmonary and cardiac congestion that accompanies acute GN, the condition can be mistaken for heart failure, especially in the older adult. The nurse should report this laboratory value so the client can undergo additional diagnostic studies. The other laboratory values are normal.
