Which laboratory tests should the nurse prepare to draw when admitting a pediatric client with possible obstructive uropathy? Select all that apply
1. Platelet count
2. Blood urea nitrogen (BUN)
3. Partial thromboplastin time (PTT)
4. Blood culture
5. Creatinine
2, 5
Explanation:
1. Platelet count is drawn when a bleeding disorder is suspected.
2. BUN is a serum laboratory test for kidney function. Obstructive uropathy is a structural or functional abnormality of the urinary system that interferes with urine flow and results in urine backflow into the kidneys; therefore, the BUN will be elevated.
3. PTT is drawn when a bleeding disorder is suspected.
4. A blood culture is done when an infectious process is suspected.
5. Creatinine is a serum laboratory test for kidney function. Obstructive uropathy is a structural or functional abnormality of the urinary system that interferes with urine flow and results in urine backflow into the kidneys; therefore, the creatinine will be elevated.
