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. 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.

A. Colonization - replicating microorganisms: not yet Infected

This pairing is correct. Colonization refers to the presence and replication of microorganisms on the wound surface. At this stage, the wound is not yet infected, as there may be microorganisms present, but they have not caused an inflammatory response or tissue damage.

B. Systemic infection - Wound is darker than the surrounding skin with noted drainage present

This description does not match the stage of systemic infection. Systemic infection refers to an infection that has spread beyond the initial wound site, affecting the entire body systemically. The symptoms of systemic infection may include fever, increased heart rate, malaise, and altered mental status. The description provided seems more indicative of a local infection with drainage.

C. Contaminated - infection beyond the wound

This pairing is incorrect. Contaminated wounds refer to wounds with a high risk of infection due to the presence of foreign material or significant contamination. However, contamination does not necessarily mean that an infection has already developed beyond the wound. It signifies a risk of infection but does not define the infection stage itself.

D. Local infection - sepsis

This pairing is incorrect. A local infection is confined to the wound site and may present with symptoms such as erythema, warmth, swelling, pain, and purulent drainage. Sepsis, on the other hand, is a severe systemic response to infection, characterized by widespread inflammation and organ dysfunction. Sepsis is not synonymous with a local infection; it represents a more advanced and life-threatening stage of infection.
