Question

2. Explain how immobility can lead to the following:

     A. Decubitus ulcers

     B. Respiratory infections

Answer 1

2, a, Decubitus ulcer:
It is also called bedsores. bedsore injure skin and underlying tissue due to prolonged pressure on the skin. prolonged sitting or lying on a particular body part failure to distribute pressure causes tissue damage. so immobility is the main cause of pressure sore development.
b, Respiratory infections:
Immobility causes thickening of mucous secretions to cause atelectasis and pneumonia. when the person does not mobilize they can not take a full breath because of position. It causes the accumulation of secretion inside the lungs that cause lung infection. mobility can loosen lung secretion.
