A bed-bound chart has a prescription for routine urinalysis. In which way does the nurse obtain the urine sample for the laboratory?
A.
Insert an indwelling urinary catheter
B.
Insert an intermittent urinary catheter
C.
Cleanse the urinary meatus and provide a sterile container
D.
Pour urine collected from a clean bedpan into a specimen cup
The correct answer and Explanation is :
Correct Answer: C. Cleanse the urinary meatus and provide a sterile container
Explanation:
Routine urinalysis is a common diagnostic test used to evaluate various aspects of kidney function and detect any abnormalities, such as infection, dehydration, or disease. For a routine urinalysis, it is essential to obtain a clean-catch midstream urine sample to avoid contamination. Here’s why Option C is the most appropriate:
- Clean-Catch Midstream Technique:
This method involves cleansing the urinary meatus (the external opening of the urethra) to minimize contamination from external bacteria or skin cells. The patient is instructed to start urinating and then, midstream, collect urine in a sterile container. This ensures the sample is as uncontaminated as possible, allowing for more accurate lab results. - Sterile Container:
Using a sterile container ensures that no foreign particles or contaminants enter the urine sample, which could alter the lab results. Clean-catch midstream samples are typically sufficient for routine urinalysis, as this technique reduces contamination from external sources.
Why Not the Other Options?
- A. Insert an indwelling urinary catheter: This is an invasive procedure and typically only indicated when a patient is unable to void on their own, requires accurate urine output monitoring, or needs a sterile sample under specific circumstances (e.g., certain types of infections). For routine urinalysis, inserting a catheter introduces unnecessary risk, such as infection.
- B. Insert an intermittent urinary catheter: While less invasive than an indwelling catheter, intermittent catheterization is also unnecessary unless the patient cannot void naturally. It should not be used routinely due to the risk of introducing pathogens.
- D. Pour urine collected from a clean bedpan: Urine collected in a bedpan is more likely to be contaminated by skin cells, bacteria, or other environmental factors, compromising the accuracy of the urinalysis.
Thus, the correct procedure for a routine urinalysis in a bed-bound patient is cleansing the meatus and using a sterile container for the sample.
