A nurse teaches a patient who is at risk for mild hypernatremia. Which statement does the nurse include in this patient's teaching?

A. Stop the infusion of IV fluids:

This action may be appropriate if there are signs of infiltration or extravasation, where the IV fluid leaks into the surrounding tissue instead of entering the vein. Stopping the infusion can help prevent further tissue damage and assess the extent of the infiltration.

B. Apply cold compresses to the IV site:

Cold compresses can help reduce swelling and discomfort at the IV site. This action may be appropriate if there are signs of local inflammation or mild irritation at the insertion site.

C. Elevate the extremity on a pillow:

Elevating the extremity can help reduce swelling and promote venous return. This action is beneficial if there is edema or localized swelling above the IV site.

D. Flush the catheter with normal saline:

Flushing the catheter with normal saline is not typically the initial action in response to edema and tenderness above the IV site. Flushing is more commonly performed to ensure patency and proper functioning of the IV catheter.

A. Excessive scarring:

Excessive scarring is not an example of a first-degree burn. It typically occurs in more severe burns that affect deeper layers of the skin, such as second-degree or third-degree burns. Second-degree burns extend into the dermis, while third-degree burns damage all layers of the skin and can lead to significant scarring. First-degree burns, on the other hand, only affect the outer layer of the skin (epidermis) and usually do not result in excessive scarring.

B. Blistering from flames:

Blistering from flames is more characteristic of a second-degree burn rather than a first-degree burn. Second-degree burns involve damage to both the epidermis and part of the dermis, which can result in blister formation. These burns are often caused by direct contact with flames, hot liquids, or steam.

C. Blackened dead skin:

Blackened dead skin is indicative of a third-degree burn, which is the most severe type of burn. Third-degree burns damage all layers of the skin, including the epidermis, dermis, and sometimes underlying tissues. The skin may appear charred or blackened, and these burns often require medical intervention, such as skin grafting, due to the extent of tissue damage.

D. A sunburn:

A sunburn is an example of a first-degree burn. It occurs due to overexposure to ultraviolet (UV) radiation from the sun, leading to redness, pain, and mild swelling of the skin. First-degree burns affect only the outer layer of the skin (epidermis) and typically heal within a few days without significant scarring or blistering. Applying soothing lotions, staying hydrated, and avoiding further sun exposure can help manage sunburns.
