Final answer:
To collect a clean catch urine specimen, clean the meatus first, then void a little into the toilet before catching the midstream urine in the container.
Step-by-step explanation:
The appropriate sequence for collecting a clean catch urine specimen is to first clean the meatus, which is the opening of the urethra. Next, the patient should begin to void a little urine into the toilet to clear the urethra of any contaminants. Then, after the initial stream, they should catch the midstream of urine in the specimen container. This helps in ensuring a sample free of external bacteria and cells, which is crucial especially when testing for urinary tract infections.
