Final answer:
To change bottom garments for someone with a urinary catheter and urine collection bag, unstrap the bag, carefully move the garment over the bag and catheter, and re-secure the bag after changing.
Step-by-step explanation:
To change the bottom garments of an individual with a urinary catheter and a urine collection bag strapped to their leg, it's important to maintain cleanliness and avoid dislodging the catheter. Firstly, unstrap the collection bag from the leg and ensure it's securely closed to prevent spillage. Gently pull the trousers or garment down to the level where the collection bag is attached. If the trousers are elasticated or have flexible openings, carefully maneuver them around the collection bag and catheter. For garments without flexible openings, it may be necessary to temporarily disconnect the catheter from the collection bag, ensuring the ends are kept sterile, or cutting the garment to allow it to pass over the bag and catheter if the clothing is to be disposed of. Re-secure the collection bag to the leg once the new garment is in place.
Throughout the process, take care to minimize any tugging or pressure on the catheter to maintain catheter integrity and patient comfort.
