A client returns to the unit after ureteroscopy with laser lithotripsy for a ureteral calculus. The nurse notes the client's urine in the collection bag is pink-tinged. The client reports mild flank discomfort rated 3/10. Which explanation best describes why pink-tinged urine is expected following this procedure?
- The client is experiencing acute kidney injury from nephrotoxic contrast dye used during the procedure.
- Pink-tinged urine indicates a urinary tract infection that developed immediately after the procedure.
- The laser energy destroys the bladder wall lining, causing bleeding from the bladder mucosa.
- The instrumentation used during the procedure causes minor mucosal irritation and small vessel trauma along the ureter.
