An 85-year-old client is experiencing uncontrollable leakage of urine with a strong desire to void and even leaks on the way to the toilet. Which priority nursing diagnosis will the nurse include in the client's plan of care?

The correct answer is C: Urge urinary incontinence. In this scenario, the client is experiencing sudden, strong urges to void leading to leakage. This is characteristic of urge incontinence, which is commonly seen in older adults due to detrusor muscle overactivity. The priority nursing diagnosis would focus on addressing the underlying cause of the urgency and implementing strategies to manage and prevent episodes of incontinence. Functional urinary incontinence (A) refers to the inability to reach the toilet due to physical or cognitive impairments, which is not the case here. Urinary retention (B) is the inability to empty the bladder fully, which is opposite to the symptoms described. Impaired skin integrity (D) may be a concern due to incontinence, but addressing the underlying urinary issue takes precedence.
