Step-by-step explanation:
The nursing diagnosis that should be prioritized in the patient's plan of care is Risk for infection related to presence of an indwelling urinary catheter. A urinary catheter increases the risk of bacteria entering the urinary tract, leading to a urinary tract infection (UTI). UTIs can be serious and have complications, especially in patients with pressure ulcers. It is important for the nurse to implement measures to prevent infection, such as ensuring proper catheter care and monitoring for signs and symptoms of infection.
