The nurse has instructed a patient on the procedure for obtaining a midstream urine specimen. The patient asks, "Why does the urine sample need to be collected in this manner?" The nurse's best response is:

"This method will prevent you from developing urinary incontinence by strengthening perineal muscles."

"By catching the middle of the urine stream, it provides time to ensure the bladder is completely empty."

"It is performed this way in order to verify fresh urine is obtained for testing, increasing accuracy."

"The initial stream flushes out microorganisms that accumulate at the opening of the urinary tract."
