During the inflammatory process, which of the following physiological responses occur?
- A. Capillaries dilate, causing erythema and increased warmth at the site of injury.
- B. Leukocytes are shunted away from the site to fight infection.
- C. Leukocytes move into the interstitial space and attack microorganisms.
- D. Red blood cells deliver more oxygen and nutrients to promote healing.
- E. Fluid in the interstitial spaces prevents redness and pain.
- F. Edema causes pressure on nerve endings, resulting in discomfort and pain.
Correct Answer: A,C,D,F
Rationale: During inflammation, capillaries dilate (erythema and warmth), leukocytes migrate to fight infection, red blood cells supply oxygen/nutrients, and edema causes pain. Leukocytes are not shunted away, and fluid does not prevent redness/pain.

- A. Serosanguineous

A patient has a black, hard, leathery scab on his left heel. The stage of this injury is
- A. Deep-tissue pressure injury.
- B. Stage 2.

A patient has had emergency surgery because of a bowel obstruction. The wound becomes infected with Escherichia coli. This likely occurred because
- A. These bacteria are always present on the skin and easily enter a wound if sterile technique is not used.
- B. These bacteria grow in the absence of oxygen, which is the case in the bowel.
- C. These bacteria are present in the bowel, and with emergency surgery there is no time to perform special bowel preparations.
- D. The patient had poor nutritional intake because these bacteria grow in dying tissue.
Correct Answer: C
Rationale: E. coli, common in the bowel, likely contaminated the wound during emergency surgery due to lack of bowel prep time.
You are a nurse, and you are running behind schedule on a very busy workday. The UAP offers to change a patient's abdominal dressing for you. She is a first-semester nursing student. Which is the most appropriate response?
- A. That would be great. Don't forget to measure the open area in the middle of her incision for me.'
- B. I know you have been taught to do this in school, so you are not the same as the other UAPs. Go ahead and change the dressing.'
- C. Thanks, but could you help Mr. Wu walk in the hall instead? That way I can get that dressing changed.'
- D. You know you can't do that as a UAP. I would be in big trouble if I let you change that dressing!'
Correct Answer: C
Rationale: UAPs, including nursing students, are not permitted to perform complex tasks like dressing changes, which require nursing judgment. Delegating a simpler task is appropriate.
A colonized wound is one in which
- A. There is potential for becoming infected.
- B. Infection is present as a result of gross contamination related to trauma.
- C. Infection is present as evidenced by high numbers of microorganisms and either purulent drainage or necrotic tissue.
- D. A high number of microorganisms are present without signs and symptoms of infection.
Correct Answer: D
Rationale: A colonized wound has many microorganisms but no clinical signs of infection, distinguishing it from an infected wound.
