A nurse is discussing laboratory values associated with the renal system with a newly licensed nurse. Which of the following statements by the newly licensed nurse indicates an understanding of the values?

Creatinine levels are increased in clients who have acute kidney injury.

BUN is decreased in clients who have dehydration

Specific gravity is decreased in clients who have hypovolemia.

Potassium levels are increased in clients who have polyuria.

Answer and Explanation

The Correct Answer is A

A.   Creatinine levels rise in acute kidney injury due to impaired kidney function, as the kidneys are unable to effectively filter creatinine from the blood.
B.   BUN (blood urea nitrogen) levels typically increase in dehydration due to reduced kidney perfusion, leading to decreased urine output and increased concentration of waste products in the blood.
C.   Specific gravity increases in hypovolemia because urine becomes more concentrated as the body tries to conserve water.
D.   Potassium levels may vary depending on the cause of polyuria, but polyuria itself does not necessarily cause hyperkalemia. It can be caused by various factors including diabetes insipidus or diabetes mellitus.
