What instruction should the nurse include in the discharge teaching for self-catheterization?

The instruction to catheterize every 3 to 4 hours is correct because it establishes a regular schedule for self-catheterization, which helps maintain bladder health and function. This frequency aids in fully emptying the bladder and preventing complications such as urinary tract infections (UTIs) or bladder overdistension.

Regular catheterization intervals are often recommended based on individual needs or specific medical conditions, but generally, every 3 to 4 hours is a standard guideline for many patients. This ensures that urine does not remain in the bladder for extended periods, which is crucial for those who may not be able to void spontaneously.

While maintaining sterile technique is important for preventing infection, the option does not provide the practical aspect pertaining to frequency and is typically expected as a standard practice rather than a specific teaching point. The Cred maneuver, which involves abdominal pressure to assist voiding, may not be relevant or necessary for all patients undergoing self-catheterization. Drinking a large volume of fluid prior to catheterization is not a standardized recommendation and might not be appropriate for everyone due to individual hydration needs or medical conditions.
