A nurse is teaching a newly hired nurse about the risks of cellulitis following an injury. Which of the following statements by the newly hired nurse shows the teaching was effective?
Explanation & Rationale
A. "Skin abrasions cause red blood cells to respond to the area of infiltration and cause inflammation.": Red blood cells are not the primary responders to bacterial invasion; inflammation is mediated mainly by immune cells such as neutrophils and macrophages, not red blood cells. B. "Skin abrasions facilitate the entry and travel of bacteria to deeper tissue layers.": Breaks in the skin, such as abrasions, compromise the protective barrier and allow bacteria to enter underlying tissues, increasing the risk of cellulitis. Understanding this mechanism reflects effective teaching about infection risk. C. "Skin abrasions only cause cellulitis when it is deep enough to impact the dermal layer of skin.": Even superficial abrasions can allow bacteria to penetrate and cause cellulitis; depth is not the only determining factor for infection. D. "Skin abrasions lead to inflammation because of the proliferation of neutrophils.": While neutrophils mediate inflammation once infection occurs, the initial risk stems from bacterial entry through the abrasion rather than neutrophil proliferation alone.
