The nurse is caring for a patient who is immobile. The nurse frequently checks the patient for impaired skin integrity. What is the rationale for the nurse's action?
a. Inadequate blood flow leads to decreased tissue ischemia.
b. Patients with limited caloric intake develop thicker skin.
c. Pressure reduces circulation to affected tissue.
d. Verbalization of skin care needs is decreased.
ANS: C
Body parts exposed to pressure have reduced circulation to affected tissue. Patients with limited caloric and protein intake develop thinner, less elastic skin with loss of subcutaneous tissue. Inadequate blood flow causes ischemia and breakdown. Verbalization is affected when altered cognition occurs from dementia, psychological disorders, or temporary delirium, not from immobility.
