The physician has ordered a urinalysis and a serum osmolality (concentration) determination. The nurse assesses that the kidneys are functioning appropriately if:
1. the serum osmolality is high and the urine osmolality is low.
2. the serum osmolality is low and the urine osmolality is high.
3. findings are incidental and unremarkable.
4. the osmolality of both the urine and the serum are high, or both are low.
4
If the blood osmolality is high, the kidneys need to dilute the blood and excrete more con-centrated urine, and the reverse is true. This helps determine the test taker's understanding of the function of the kidneys.
