Easy
Identify the following device?
Appeared in: AIIMS Rishikesh NO - 2019
Explanation
- The image displays a flexible tube with two lumens, which is characteristic of a Foley's catheter.
- One lumen serves as the main channel for urine drainage from the bladder.
- The second lumen, connected to the red-capped port, is an inflation channel for a retention balloon at the tip, which holds the catheter in place within the bladder.
- This device is specifically designed for continuous, indwelling urinary drainage.
Why Other Options Were Wrong
- Option B: A Carman catheter is a flexible cannula used for uterine aspiration, such as in manual vacuum aspiration (MVA) procedures. It is not used for urinary drainage and lacks a retention balloon.
- Option C: K-95 catheter is not a standard or recognized term for a medical catheter in clinical practice. It serves as a plausible but incorrect distractor.
- Option D: An NG (Nasogastric) tube is inserted through the nostril, down the esophagus, and into the stomach. It is used for feeding, administering medications, or draining stomach contents. It is functionally and structurally different from a urinary catheter.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of common medical devices used in nursing practice as background academic context rather than a clinical decision trigger.
- Nurses are responsible for the sterile insertion, maintenance, and timely removal of Foley's catheters to prevent Catheter-Associated Urinary Tract Infections (CAUTIs), a common healthcare-associated infection.
- Proper care includes regular perineal hygiene, ensuring the drainage bag is kept below the bladder level to prevent backflow, and monitoring for signs of infection such as fever, cloudy urine, or discomfort.
- What if? If a patient only requires bladder emptying at intervals rather than continuously, an intermittent (or straight) catheter would be used. This type of catheter is inserted to drain the bladder and then immediately removed, reducing the risk of infection associated with an indwelling device.
How to Approach the Question
- First, carefully examine the image provided, noting the key physical characteristics of the device.
- Observe the flexible, yellowish tube, the Y-split at one end creating two ports, and the colored cap on one of the ports.
- Relate these features to your knowledge of common medical tubes and catheters. The presence of an inflation port strongly suggests a device with a retention balloon.
- Evaluate the given options. 'Foley's Catheter' is the standard term for an indwelling urinary catheter with a retention balloon.
- Eliminate the other options based on their different functions and structures: a Carman catheter is for uterine procedures, an NG tube is for gastric access, and 'K-95' is not a standard device.
