A nurse is teaching a client who reports insomnia about promoting rest and sleep. Which of the following statements should the nurse identify as an indication that the client understands the instructions?

A. This vitamin is essential for wound healing. It plays a critical role in cellular immune responses, skin integrity, and the repair of epithelial tissues. Vitamin A helps in the formation of new skin cells and promotes collagen synthesis, which is vital for wound healing.
B. While vitamin D is crucial for bone health and calcium absorption, its direct role in wound healing is less pronounced compared to other nutrients. Vitamin D supports overall immune function, which can indirectly support the healing process, but it is not as directly involved in wound repair as vitamin A or other specific nutrients.
C. Vitamin B1 is important for carbohydrate metabolism and nerve function, but its direct role in wound healing is minimal compared to other vitamins. While essential for overall health, vitamin B1 does not specifically target wound healing processes.
D. Calcium is crucial for bone health and muscle function. It plays a role in blood clotting and can support overall health, but its direct impact on wound healing is less significant compared to nutrients like vitamin A and vitamin C.

A. The client may have difficulty voiding despite being taken to the bathroom, especially if there is an underlying issue such as urinary retention or an obstruction. Therefore, this step is usually taken after assessing the situation further.
B. Inserting a straight catheter is an invasive procedure that should not be the initial action. It is typically done after other non-invasive measures have been taken to evaluate the reason for the lack of voiding. Straight catheterization can be considered if other methods do not resolve the issue or if there is a clear indication of urinary retention that needs immediate intervention.
C. Performing a bladder scan is the appropriate first step. A bladder scan, or portable ultrasound, helps assess the amount of urine in the bladder and determines if the client is retaining urine. This non- invasive procedure can provide valuable information about the presence of urinary retention, which guides further intervention.
D. Increasing fluid intake might be appropriate if the client is dehydrated or has not been drinking enough fluids. However, this step is not the first action to take if the client has not voided for 8 hours. The priority is to determine if there is a physiological issue, such as urinary retention, before increasing fluids.
