The correct answers for a patient with chronic kidney disease (CKD) would be:
A. Anemia - CKD can lead to anemia due to decreased erythropoietin production and reduced kidney function.
B. Increased blood pressure - CKD is often associated with hypertension due to fluid overload and other factors.
C. Increased GFR - This is incorrect. Chronic kidney disease typically results in a decreased glomerular filtration rate (GFR).
D. Increased erythropoietin production - This is incorrect. In CKD, the production of erythropoietin decreases, leading to anemia.
Therefore, the correct answers are A and B.
