A client with a sprained ankle is seen at the clinic and is given a pair of crutches. When the client stands with the aid of the crutches, the nurse notes a space of three finger-widths between the top of the crutch and the client's axilla. Which action should the nurse take?

A. Assess the client for signs of diminished circulation in the hands is unnecessary at this stage, as the primary concern is ensuring proper crutch fit and teaching safe use. B. Proceed with teaching the client how to walk with the crutches is correct because a space of three finger-widths between the crutch and the axilla indicates proper crutch height. This prevents nerve damage and discomfort in the axilla. C. Ask the client to sit down while the crutch length is adjusted is not needed since the crutches are already appropriately adjusted based on the observed spacing. D. Confer with the physical therapist for correct crutch size is unnecessary because the nurse can confirm that the crutches are properly fitted based on standard guidelines.
