Final answer:
The catheter tubing should be placed under the leg while the resident is in bed.
Step-by-step explanation:
When caring for a resident with a urinary catheter, the catheter tubing should be placed under the leg while the resident is in bed. This positioning helps to prevent any kinks or obstructions in the tubing, ensuring that urine can flow freely from the resident's bladder to the collection bag. Placing the tubing under the leg also helps to maintain proper alignment and prevent accidental dislodgement of the catheter.
