Correct Answer is A
Explanation
A. These values indicate elevated BUN (blood urea nitrogen) and creatinine levels indicating impaired kidney function, typical findings in chronic kidney disease.
B. These are the normal BUN and creatinine levels hence are not indicative of chronic kidney disease.
C. These values are within the normal BUN and creatinine levels hence are not indicative of chronic kidney disease.
D. These are normal BUN and creatinine levels and are not indicative of chronic kidney disease.
Correct Answer is A
Explanation
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.
