How should a urine specimen be collected according to nursing procedures?

• A. Via clean catch method
• B. Via catheterization
• C. Via midstream urine sample
• D. Via bag collection

Answer: (B)

The collection of a urine specimen via catheterization is a method used when a sterile sample is required, particularly in cases where the patient may have difficulties providing a clean catch sample or when precise measurements of the urine are needed. Catheterization allows health care providers to access the bladder directly, thus minimizing contamination from the urethra, genital area, or outside environment, which is especially important for certain diagnostic tests. This method is often employed in clinical settings when an accurate urine analysis is critical, such as in patients with urinary retention or those who cannot urinate. While other methods such as the clean catch and midstream collection techniques are also valid for obtaining urine specimens, they do not guarantee the level of sterility that catheterization provides. A bag collection is typically suitable for infants or young children but carries a higher risk of contamination. Therefore, catheterization is a reliable approach when a high level of sterility is necessary or when other methods are impractical.
