Final answer:
The charge nurse would intervene if the student nurse selects stockings that are too tight, rolls the stockings down below the knee, or applies the stockings unevenly.
Step-by-step explanation:
When assisting a student nurse in applying knee-length compression stockings onto a client with chronic venous insufficiency, the charge nurse would intervene if the student nurse performs any of the following actions:
- Selecting stockings that are too tight and constrictive
- Rolling the stockings down below the knee
- Applying the stockings unevenly, causing wrinkles or folds
Compression stockings should provide a snug but comfortable fit, evenly distributing pressure along the leg. They should be applied smoothly without wrinkles or folds to ensure proper compression and blood flow.
