Problem: Which instruction given to a client clearly details how to collect a clean-catch urine specimen? Insert a needle through the abdomen and aspirate the amount of urine needed for the specimen. Initially put on a pair of sterile gloves, then start the flow of urine and collect the entire stream. Clean the external urethral opening and then collect the urine in the middle of the stream. Go to the bathroom and once the stream starts to flow, catch the specimen. Need Assignment Help?
