A nurse is caring for a client who is postoperative. Which of the following actions should the nurse take to help prevent an incisional infection?

The correct answer is: a. Edema.

Choice A: Edema

Edema is swelling caused by excess fluid trapped in the body’s tissues. It is a common sign of inflammation and infection. When a wound becomes infected, the body’s immune response can cause increased fluid accumulation in the affected area, leading to noticeable swelling. This swelling is often accompanied by redness, warmth, and pain, which are classic signs of infection.

Choice B: Petechiae

Petechiae are small, red or purple spots caused by bleeding into the skin. They are not typically associated with wound infections but rather with conditions that cause bleeding or clotting disorders. Petechiae do not indicate an infection but rather a different underlying issue that may require further investigation.

Choice C: Urticaria

Urticaria, also known as hives, is a skin reaction that causes itchy welts. It is usually a result of an allergic reaction and is not a sign of wound infection. Urticaria is characterized by raised, red, itchy bumps on the skin and does not typically occur in response to an infected wound.

Choice D: Crusting over granulated tissue

Crusting over granulated tissue is a normal part of the wound healing process. Granulation tissue forms as the wound heals, and a crust or scab may develop over it to protect the new tissue underneath. This is not an indication of infection but rather a sign that the wound is progressing through the healing stages.

Choice A reason: When a patient has an elevated temperature, the body is attempting to cool down through vasodilation, which is why the skin may appear flushed and feel warm. Removing excess blankets can help facilitate the body's natural cooling process. Offering fluids is also crucial as fever can lead to dehydration, especially if there is sweating. Adequate hydration helps regulate body temperature and replaces fluids lost through sweating. The normal body temperature range is typically between 36.5°C to 37.5°C (97.7°F to 99.5°F). When the body temperature rises above this range, interventions such as removing blankets and providing fluids can be effective in reducing fever.

Choice B reason: Increasing the patient's activity is not advisable when they have an elevated temperature and are experiencing severe fatigue. Activity generates heat and can raise body temperature further, exacerbating the fever. Rest is recommended to conserve energy and reduce metabolic demand, which can help lower the body temperature.

Choice C reason: The use of ice bags can be a rapid cooling measure but must be used with caution. Direct application of ice to the skin can cause vasoconstriction and shivering, which can actually increase the body's core temperature. It is generally reserved for hyperthermia or heatstroke when immediate cooling is necessary. For a simple fever, less aggressive cooling measures are usually preferred.

Choice D reason: Decreasing the patient's intake is not appropriate unless there is a specific contraindication, such as vomiting or risk of aspiration. Adequate nutrition supports the immune system and provides the energy needed for the body to combat the underlying cause of the fever.
