Correct Answer is B
Explanation
A. pH 5.0: This is within normal range (urine pH typically ranges from 4.5 to 8.0).
B. Large amount of white blood cells (WBC): A high WBC count in urine indicates possible infection or inflammation, such as a urinary tract infection (UTI), and should be reported.
C. Amber color: Normal urine is straw to amber in color, depending on hydration status. This is not abnormal.
D. Occasional casts: Occasional hyaline casts may be seen in healthy individuals, especially after exercise. Persistent or abnormal casts (e.g., RBC casts) would be more concerning.
Correct Answer is C
Explanation
A. Glycosuria: This is glucose in the urine, often caused by diabetes mellitus, not erythropoietin deficiency.
B. Polyuria: This refers to excessive urination and is unrelated to erythropoietin levels.
C. Anemia: Erythropoietin stimulates red blood cell production, so its deficiency leads to reduced RBCs, resulting in anemia.
D. Oliguria: Oliguria is low urine output often related to renal perfusion issues, not directly to erythropoietin.
