What is true about the urine osmolality when the kidney is adequately functioning?
Equal to the excretion of urea
In a ratio of 10:1 with the serum
Approximately half of the serum
Equal to the osmolality of the serum
The Correct Answer is D
A. Equal to the excretion of urea: Urea excretion contributes to osmolality but does not define it.
B. In a ratio of 10:1 with the serum: This is not a recognized ratio for urine and serum osmolality.
C. Approximately half of the serum: In a healthy kidney, urine osmolality may vary but typically equals serum osmolality in a state of balance.
D. Equal to the osmolality of the serum: Under normal conditions, the kidney regulates urine osmolality to maintain a balance with serum osmolality, reflecting adequate kidney function.

Correct Answer is A
Explanation
A. Bleeding from the kidney: Dark red urine often indicates bleeding from the upper urinary tract, including the kidneys, due to trauma, infection, or stones.
B. Dehydration: Dehydration typically causes concentrated urine with a darker yellow color, not red.
C. Bleeding from the lower urinary tract: Bleeding from the lower urinary tract usually results in bright red urine, not dark red urine.
D. Excessive red meat in the patient's diet: While dietary factors can influence urine color (e.g., beets), red meat does not cause dark red urine.
Correct Answer is B
Explanation
A. Specific gravity: Specific gravity measures urine concentration but does not directly assess renal function.
B. Creatinine: Serum creatinine levels provide the most accurate measure of renal function as they reflect the kidney’s ability to filter waste.
C. Phosphates: Phosphate levels are affected by kidney function but are not the most direct measure.
D. BUN: Blood Urea Nitrogen (BUN) can be affected by other factors like hydration and protein intake, making it less reliable than creatinine.
