A nurse is changing the dressing on a client's wound. The nurse should recognize that which of the following findings is an indication of a wound infection?

Edema

Petechiae

Urticaria

Crusting over granulated tissue

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is A

Explanation

Choice A reason: Urinary catheterization is a well-known risk factor for HAIs, particularly catheter-associated urinary tract infections (CAUTIs). The use of indwelling urinary catheters can introduce bacteria into the urinary tract and is associated with a significant proportion of HAIs.

Choice B reason: While malnutrition can affect the immune system and increase the risk of infections, it is not a direct cause of HAIs. Good nutritional status is important for wound healing and infection prevention, but it does not cause HAIs by itself.

Choice C reason: Having multiple caregivers can increase the risk of transmitting infections, especially if hand hygiene and other infection control practices are not consistently followed. However, it is not considered a direct cause of HAIs like urinary catheterization is.

Choice D reason: Chlorhexidine washes are actually used as a preventive measure against HAIs, particularly in reducing the risk of surgical site infections. They are not a cause of HAIs but rather part of the solution to prevent them.

A. Wrapping the cuff too loosely around the client's arm B. Measuring blood pressure right after the client's mealtime C. Positioning the client's arm above heart level D. Deflating the cuff too slowly

Correct Answer is C

Explanation

The correct answer is: c. Positioning the client’s arm above heart level.

Choice A: Wrapping the cuff too loosely around the client’s arm

Wrapping the cuff too loosely can lead to an inaccurately high blood pressure reading, not a low one. A loose cuff does not compress the artery properly, causing the device to overestimate the pressure needed to occlude the artery.

Choice B: Measuring blood pressure right after the client’s mealtime

Measuring blood pressure right after a meal can cause a slight increase in blood pressure due to the body’s metabolic response to digestion. This is not a common cause of a low blood pressure reading.

Choice C: Positioning the client’s arm above heart level

Positioning the client’s arm above heart level can lead to an inaccurately low blood pressure reading. When the arm is elevated, the hydrostatic pressure decreases, resulting in a lower reading. This is a well-known source of error in blood pressure measurement.

Choice D: Deflating the cuff too slowly

Deflating the cuff too slowly can cause venous congestion, which may lead to an inaccurately high reading rather than a low one. The standard deflation rate is 2-3 mm Hg per second to ensure accurate measurement.
