Ch. 4 Flashcards
Cell Proliferation and Tissue Regeneration and Repair
Skin assessment of African American client, notes of the healed wound on the leg but excess of scar tissue. The nurse documents this as which of the following?
Keloid p. 81
large leg wound…notes client’s past medical history includes diabetes, chronic atrial fibrillation, asthma, and neuropathy. Which one has the greatest potential to negatively impact the healing of the client’s wound?
Diabetes p.84
Some tissues, such as the mucosal surface of the GI tract have cells that are capable of cell division and serve as reserve source for specialized cells. Which term describes these cells?
Stem cells p.72, 73, 76
When caring for a client with a wound that is healing by primary intention the nurse recognized which of these best describes this type of wound?
Surgical incision p.79
Client w/ hypovolemic shock secondary to penetrating multiple trauma. post-op which factors places the client at risk for poor wound healing?
Tissue hypoxia p. 83-84
select the statement that best describes stem cells
Undifferentiated cells of continuously dividing tissues that have the capacity to generate multiple cell types. p. 73
Cigarette smoker had a mass removed from the lung. He will have a good amount of fibrosis developed in the surgical area. Fibrosis is described as:
Result in replacement tissue in the form of connective (fibrous) tissue which leads to scar formation or fibrosis of the lung. p. 71
Researchers wish to reactive the cell cycle in nonproliferating cells to assist the body to repair tissue. To reactivate the cycle, which substance will the researchers need to remove from the cell?
CDK inhibitors P.73
While reviewing the phases of wound healing, the students note that the first cells to arrive after injury are the:
neutrophils p.80
Describe the process resulting in specialized cells.
Differentiation p. 71-72
which stage of a cell’s life cycle is where the preparation of mitosis occurs?
G1 p.72-73
An infected burn of the arm is an example of wound healing by primary or secondary intention?
secondary p. 79-80
Post-op patient documents that the surgical incision is healing by which of the following?
primary intention p. 79
To promote wound healing, which nutrient does the nurse encourage to consume?
Vit. C p.81
What happens if, in the process of going through the cell cycle, a cell is damaged?
There are built in checkpoints in the cell cycle to allow for defects to be edited and repaired p. 72
