The nurse will need to assess the client’s performance of clean intermittent self-catheterization (CISC) for a client with which urinary diversion?

Clean intermittent self-catheterization (CISC) is a technique where individuals insert a catheter into the bladder at regular intervals to drain urine, then remove it immediately afterward, rather than leaving it in place; it is commonly used for patients with neurogenic bladder, chronic urinary retention, or incomplete bladder emptying, and is preferred over long-term indwelling catheters because it reduces the risk of infection, preserves bladder function, and promotes independence.

Rationale for correct answer:

2. Kock pouch: This is a continent cutaneous urinary diversion. The surgeon creates an internal reservoir from the small intestine. A “nipple” valve is created so urine does not leak out. Because there is no external bag, the client must perform CISC every 4–6 hours to empty the internal pouch through the stoma.

Rationale for incorrect answers:

1. Ileal conduit: This is an incontinent urinary diversion. The ureters are connected to a piece of the ileum, which opens onto the abdominal wall as a stoma. Urine drains continuously into an external collection bag. No catheterization is required.

3. Neobladder: A neobladder is an internal reservoir connected to the urethra. Ideally, the client voids by relaxing the pelvic floor and using the Valsalva maneuver (bearing down). While some neobladder patients may occasionally need to catheterize if they can't empty fully, it is not the standard primary method of emptying as it is for a Kock pouch.

4. Vesicostomy: This is a simple opening made directly from the bladder to the abdominal wall, common in pediatrics. It usually drains directly into a diaper or an appliance; while it can be catheterized, the Kock pouch is the definitive answer for a diversion requiring a formal CISC schedule.

Test taking strategy:

Ask: “How is urine emptied?”

• External bag - no catheter
• Internal pouch with stoma - catheter required

Continent diversions store urine thus needs to be emptied.

Take home points:

• An ileal conduit is “incontinent” - needs a bag.
• A Kock pouch is “continent” - needs a catheter.
• For patients with a Kock pouch, learning CISC is essential for survival and social continence, as the pouch can rupture if not emptied regularly.

Collecting a urine specimen for routine urinalysis involves obtaining a clean, midstream sample to ensure accuracy and reduce contamination; the patient is instructed to wash their hands, cleanse the genital area, begin urinating into the toilet, then collect the midstream portion in a sterile container, sealing it promptly and labeling it correctly. The specimen should be delivered to the laboratory as soon as possible - ideally within one hour - or refrigerated if delayed, since prolonged standing can alter results.

Rationale for correct answer:

2. Results may be altered if a sample is left standing at room temperature for a long time: If urine sits at room temperature for longer than 1 hour, it begins to decompose. Bacteria multiply, the pH becomes more alkaline as urea converts to ammonia, and glucose levels may drop as bacteria consume it. If the sample cannot be sent to the lab immediately, it must be refrigerated.

Rationale for incorrect answers:

1. A sterile specimen is required for collection: A routine urinalysis does not require a sterile specimen. It is a clean procedure, not a surgical one. A sterile specimen is only required for a urine culture and sensitivity to identify specific bacteria.

3. The external meatus requires cleaning with antiseptic soap and water before voiding: While the area should be generally clean, the formal “antiseptic wipe” procedure is specifically for a clean-catch midstream specimen. For a routine urinalysis, the client can simply void into a clean container.

4. A clean-catch midstream specimen is necessary: While a clean-catch is the “gold standard” for avoiding contamination, it is not strictly necessary for a routine screening urinalysis. A simple “random” specimen is usually sufficient unless the provider specifically orders a clean-catch or a culture.

Test taking strategy

• In nursing exams, look for the answer that addresses specimen integrity.
• Options 1, 3, and 4 are “best practice” for cultures, but Option 2 is a universal rule for all urine samples.

Take home points:

• Urine is a living medium; to get accurate results for pH, nitrites, and bacteria, the lab must receive the specimen within 1 hour or it must be cooled to pause bacterial growth.
• Always distinguish between a routine urinalysis (tests for chemistry/blood/protein) and a culture (tests for specific bacteria).
• Cultures require sterile technique; routine urinalysis do not.
