Final answer:
The nurse should protect an older patient's skin during dressing removal by pushing the skin away from the adhesive to prevent tearing and injury due to the skin's reduced elasticity and thinness.
Step-by-step explanation:
Considering the characteristics of older patients' skin, such as reduced elasticity and thinness due to aging, the nurse should protect the patient's skin during dressing removal by pushing the skin away from the adhesive. This technique minimizes trauma and potential tearing of the skin, which is more fragile in the elderly due to factors like decreased collagen and elastin production, as well as a reduction in the regenerative capacity of the dermis. Performing this action carefully can help prevent skin injury and promote better wound healing in older patients, taking into consideration their more delicate integumentary system.
