Answer to Question 1
B
Feedback:
The nurse should understand that during the second stage of the inflammatory phase, the body keeps producing more white blood cells. A second wave of defense follows the local changes when leukocytes and macrophages (types of white blood cells) migrate to the site of injury, and the body produces more and more white blood cells to take their place. During the first stage, local changes occur. Immediately following an injury, blood vessels constrict to control blood loss and confine the damage. Shortly thereafter, the blood vessels dilate to deliver platelets that form a loose clot. The membranes of the damaged cells become more permeable, causing the release of plasma and chemical substances that transmit a sensation of discomfort.
Answer to Question 2
B
Feedback:
The proliferation phase is the period during which new cells fill and seal a wound. This phase occurs from 2 days to 3 weeks after the inflammatory phase. The inflammatory phase is the physiologic defense immediately after tissue injury. Resolution is the process by which damaged cells recover and reestablish their normal function. Remodeling follows the proliferation phase and is the period during which the wound undergoes change and maturation.
