A. Measure the patient's urinary output: Measuring output is important but not the priority. First, the nurse must ensure that urine can drain freely. B. Ensure that the catheter tubing is not kinked: This is the priority. A kinked catheter can cause bladder distention and discomfort, leading to a sensation of urgency despite the catheter being in place. C. Provide perineal care to the patient for comfort: Comfort is important, but it does not address the potential cause of the urinary sensation. D. Reassure the patient that the sensation is to be expected: Sensation may be expected in some patients, but it’s essential to rule out mechanical obstruction first.
