An elderly client has experienced some hypoxia as a result of chronic respiratory problems. Knowing that oxygen -deprived cells result in an accumulation of lactic acid in the cells, physiologically, the client may experience:

Question

A) An increase in fat load
B) Altered cell membrane permeability
C) Retention of lysosomal enzymes
D) Cellular shrinkage and dehydration

Answer 1

Ans: B
Feedback:
Altered membrane permeability impairs the balance, allowing too much of some and not enough of other substances to flow in and out of the cell. The altered permeability, lack of ATP, and loss of functional surface receptors make it difficult for glucose to enter the cell. Excess fat accumulates because it is unable to move through the damaged membrane. Injury to the lysosomal membranes results in the leakage (not retention) of destructive lysosomal enzymes into the cytoplasm and enzymatic digestion of cell components.
