For a client who had a kidney transplant 4 days ago, which assessment findings are of greatest concern?

• A. Urine output 20 mL/hr
• B. Urine output 7 mL/hr
• C. Hemoglobin 12 g/dL
• D. Creatinine 1.5 mg/dL

Answer: (B)

The assessment finding of urine output at 7 mL/hr is of greatest concern for a client who had a kidney transplant just 4 days ago. After a kidney transplant, patients should exhibit signs of adequate renal function, typically indicated by appropriate urine output. Normal urine output is generally expected to be at least 30 mL/hr for a healthy kidney.

A urine output of 7 mL/hr suggests a significant reduction in renal function or potential acute rejection or acute kidney injury, which are critical complications to monitor for in the postoperative period. This low urine output indicates that the transplanted kidney may not be functioning properly, which requires immediate investigation and likely intervention to prevent further renal impairment.

Monitoring urine output post-transplant is crucial, as it can be an early indicator of transplant rejection or other complications. In contrast, urine output of 20 mL/hr, hemoglobin of 12 g/dL, and creatinine levels of 1.5 mg/dL may still fall within acceptable limits or may not require immediate concern but should be interpreted alongside the patient’s overall clinical picture and trends in lab values. Therefore, the significantly low urine output at 7 mL/hr raises the most alarm and necessitates further evaluation.
