A frail, older adult home health patient who had chickenpox as a child has been exposed to varicella (chickenpox) several days ago. What should the nurse do?

A. Decreased plasma volume:Burn injuries cause a significant inflammatory response, leading to fluid shifts from the intravascular space to the interstitial space. This results in hypovolemia and decreased plasma volume, especially during the acute phase of burns.

B. Diuresis:Diuresis typically occurs after fluid resuscitation and stabilization of the client (in the later phase of burn recovery). In the initial phase, oliguria is more common due to hypovolemia and reduced renal perfusion.

C. Hypermagnesemia:Hypermagnesemia is not typically associated with burn injuries. Instead, clients with burns often experience hypomagnesemia due to fluid shifts, protein loss, and increased renal losses.

D. Capillary leak:Burn injuries lead to a systemic inflammatory response, causing capillary leak syndrome. This increases vascular permeability, allowing fluid, electrolytes, and proteins to leak into the interstitial spaces, contributing to edema and hypovolemia.

E. Loss of protein:Proteins are lost through damaged capillaries and open burn wounds, contributing to decreased oncotic pressure, edema, and a need for aggressive nutritional support to promote healing and recovery.

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.
