A 22-year old patient presented with a very deep (3 cm) skin laceration due to an accident that had occurred 3 days prior. The wound was red, hot to the touch, and swollen. A Staph. aureus infection was also diagnosed. Which of the following statements pertaining to this case is correct?:Question 2Select one:a.The redness of the wound is due to arteriolar vasodilation.b.Once the bacterial infection was resolved, the would would heal to complete resolution.c.The swelling in the wound is due to a hemorrhagic exudate.d.The exudate produced in the wound is a serous exudate.e.The Staph. aureus infection would likely speed up wound healing.

The correct statement pertaining to this case is: "The redness of the wound is due to arteriolar vasodilation."

Explanation:

a. The redness of the wound is due to arteriolar vasodilation. This is correct. In response to injury and inflammation, the body increases blood flow to the affected area. This is achieved by vasodilation of the arterioles, which results in redness and heat.

b. Once the bacterial infection was resolved, the wound would heal to complete resolution. This is not necessarily true. Deep wounds, especially those that are 3 cm deep, may not heal completely and can leave a scar.

c. The swelling in the wound is due to a hemorrhagic exudate. This is not necessarily true. Swelling or edema in a wound is usually due to an inflammatory exudate, which is a fluid that leaks out of blood vessels due to increased permeability in response to inflammation. A hemorrhagic exudate, which contains a high concentration of red blood cells, is usually associated with trauma or serious injury.

d. The exudate produced in the wound is a serous exudate. This is not necessarily true. The type of exudate can vary depending on the stage and severity of the wound. In this case, with a deep wound and bacterial infection, the exudate is more likely to be purulent (containing pus), not serous.

e. The Staph. aureus infection would likely speed up wound healing. This is incorrect. Bacterial infections generally delay wound healing by causing further tissue damage and inflammation.
