A nurse is caring for a 70-year-old client who has a pressure injury in the coccyx area. The nurse identifies that which of the following factors associated with aging may impact the ability for the ulcer to heal?

This scenario focuses on age-related physiological changes that impede wound healing. Knowledge of geriatric nutrition, skin integrity, and the role of protein in collagen synthesis and tissue repair is necessary to evaluate the healing potential of ulcers. Choice A rationale . Low bone density, or osteoporosis, affects skeletal strength and increases fracture risk. However, it does not directly impair the cellular processes of soft tissue repair or the inflammatory phase required for a pressure injury to heal effectively. Choice B rationale . Elevated hemoglobin levels would typically suggest polycythemia or dehydration. For wound healing, low hemoglobin (anemia) is usually the concern, as it reduces oxygen delivery to tissues. Normal hemoglobin ranges are 12 to 18 g/dL depending on sex. Choice C rationale . Aging often involves decreased protein levels due to poor intake or malabsorption. Protein is essential for collagen synthesis and immune function. Serum albumin levels below 3.5 g/dL are strongly associated with impaired wound healing and tissue breakdown. Choice D rationale . Increased muscle mass would generally support better metabolic health and circulation. However, aging is characteristically associated with sarcopenia, which is the loss of muscle mass, rather than an increase, which contributes to overall physical frailty.
