Intensive Care Medicine (ICM) Practice Exam

Which of the following is a valid indication for catheterization of the urinary bladder?

1. Relieve bladder distention

2. Monitor urine output

3. Sterile sample

4. All of the above

The correct answer is: All of the above

Catheterization of the urinary bladder serves several important clinical purposes, making it valid for a variety of indications, which is why all the options fit within the reasoning for catheterization. Relieving bladder distention is crucial in patients who cannot void due to obstruction or neurological deficits. This procedure alleviates discomfort and potentially prevents complications such as bladder overdistension, which can lead to urinary retention or damage. Monitoring urine output is vital in critical care settings, as urine production can serve as an important indicator of renal function and overall fluid balance. Accurate measurement of urine output assists healthcare providers in assessing a patient's hydration status and response to treatment, especially in critically ill patients. Obtaining a sterile urine sample is particularly important for diagnosing urinary tract infections (UTIs) and other urinary conditions. Catheterization can ensure that the sample collected is free from contamination, providing reliable results. Given these scenarios, catheterization of the urinary bladder is indeed justified for all the reasons mentioned, thereby making the selection of all the provided options as a valid answer.
