The nurse should be aware that a pessary is most effective in the treatment of what disorder?

A. Cystocele: A cystocele involves the anterior vaginal wall and bladder prolapse. While a pessary may provide some support, it is not the primary treatment of choice specifically for cystocele; other interventions like pelvic floor exercises are usually preferred. B. Uterine prolapse: A pessary is a medical device inserted into the vagina to provide structural support to the uterus that has descended into or beyond the vaginal canal. It is most effective for relieving symptoms of uterine prolapse, preventing further descent, and improving quality of life when surgery is not immediately indicated. C. Rectocele: Rectocele involves prolapse of the posterior vaginal wall and rectum. Pessaries may provide limited support, but targeted pelvic floor therapy or surgical repair is typically more effective. D. Stress urinary incontinence: Stress incontinence is caused by weakened pelvic floor muscles leading to urine leakage during activities that increase intra-abdominal pressure. While pessaries may help in some cases, they are not the primary or most effective treatment for this condition.
