Review Question - QID 213178

A 46-year-old woman presents to the clinic complaining that she “wets herself.” She states that over the past year she has noticed increased urinary leakage. At first it occurred only during her job, which involves restocking shelves with heavy appliances. Now she reports that she has to wear pads daily because leakage of urine will occur with simply coughing or sneezing. She denies fever, chills, dysuria, hematuria, or flank pain. She has no significant medical or surgical history, and takes no medications. Her last menstrual period was 8 months ago. She has 3 healthy daughters that were born by vaginal delivery. Which of the following tests, if performed, would most likely identify the patient’s diagnosis?
