Final answer:
a) "I should collect the urine midstream to avoid contamination."
The correct client statement indicating she has understood how to collect a clean-catch urine specimen is "I should collect the urine midstream to avoid contamination." This method ensures specimen integrity for accurate culture results.
Step-by-step explanation:
The clinic nurse has instructed a female client on how to collect a clean-catch urine specimen for culture and sensitivity. Among the provided options, the statement from the client indicating effective teaching is "I should collect the urine midstream to avoid contamination." This method is essential for avoiding contaminants normally present around the urethra and maintaining the specimen's integrity for accurate culture results.
It's also recommended to use a sterile container for the collection to prevent any external contamination. Refrigerating the specimen may be necessary if there's a delay in delivering it to the clinic to inhibit bacterial growth that could compromise the results.
