When planning care for a cardiac patient, the nurse knows that in response to an increased workload, the cardiac cells will

A. regeneration: Regeneration replaces lost cells with the same cell type (restores normal tissue) and usually does not produce a scar when full regeneration occurs.
B. remodeling: Remodeling is the maturation and reorganization of the repair tissue (collagen), which shapes the scar but is part of the healing process rather than the initial cause of scarring.
C. granulation: Granulation tissue is rich in new capillaries and fibroblasts and is a stage in healing that precedes scar formation, but granulation itself is not the final scar.
D. fibrous connective tissue repair: Scar formation results from replacement of normal tissue by fibrous (collagenous) connective tissue-i.e., fibrous connective tissue repair (repair rather than regeneration).

A. continually divide throughout life: This describes labile cells (e.g., epithelial cells of skin, GI tract) - not facultative mitotic cells.
B. kidney cells are facultative mitotic cells: Many renal epithelial cells (e.g., tubular cells) are stable/facultative - they do not constantly divide but can re-enter the cell cycle after injury.
C. replaced by fibrous scarring after trauma: If injury is severe and regeneration fails, even facultative cells may be replaced by scar tissue, but this is not the defining property of facultative mitotic cells.
D. divide when required: Correct description of facultative (stable) cells - they remain quiescent normally but divide when needed (e.g., after injury).
E. Two answers are correct: Both B and D are correct statements about facultative mitotic cells.
F. None are correct: Some choices (B and D) are correct.
