Final answer:
The correct procedure for maintaining an indwelling urinary catheter is to regularly clean the catheter insertion site, ensure proper positioning of the catheter, and monitor urine output and color, which means all the options provided are correct.
Step-by-step explanation:
The correct procedure for maintaining an indwelling urinary catheter is all of the above. Proper maintenance of an indwelling catheter is crucial to prevent complications such as infections, blockages, and damage to the urethra. This includes consistent and thorough cleaning of the catheter insertion site, which is crucial for preventing infections. It's also essential to ensure that the catheter is correctly positioned to prevent kinks and pressure spots, which can interfere with urine flow and cause discomfort or injury. Monitoring urine output and color provides valuable insights into the patient's hydration status, kidney function, and potential issues like bleeding or infection. Abnormalities in the volume, color, or presence of blood can signal the need for medical attention.
Moreover, maintaining the urinary system's health supports the body's ability to filter blood, excrete wastes, and maintain homeostasis, including proper ion and water balance.
