A nurse in a busy emergency department provides care for many clients who present with contusions, strains, or sprains. What are treatment modalities that are common to all of these musculoskeletal injuries? Select all that apply.

A. Increased thickness of the subcutaneous skin layer - Aging typically results in thinning of the skin and subcutaneous tissue, making older adults more vulnerable to pressure ulcers rather than having increased thickness.

B. Changes in the character and quantity of bacterial skin flora - This is a common age-related change; however, it is not directly related to the course of treatment for a sacral pressure ulcer. Proper wound care can mitigate the impact of changes in skin flora.

C. Increased time required for wound healing - Aging often leads to a decline in the body's ability to repair and regenerate tissues, which can prolong the healing process of wounds, including pressure ulcers. Older adults may experience delayed wound healing compared to younger individuals.

D. Increased elasticity of the skin - Skin elasticity decreases with age, making older adults more susceptible to skin breakdown and pressure ulcers due to reduced skin resilience and ability to redistribute pressure. Increased elasticity would not affect the course of treatment positively but rather negatively in this context.

A. Applying ice intermittently - Ice application helps reduce swelling and inflammation by constricting blood vessels. It is effective in managing pain and preventing further tissue damage in contusions, strains, and sprains.

B. Elevating the injured limb - Elevating the injured limb above the level of the heart helps reduce swelling by allowing fluids to drain away from the injured area. This is particularly important in managing contusions, strains, and sprains where swelling is a common symptom. Elevation supports the body's natural healing processes.

C. Resting the affected extremity - Rest is essential to allow the injured tissue to heal. Avoiding movement and stress on the affected area prevents further damage and promotes the healing process. Resting the extremity prevents additional strain on the injured muscles, ligaments, or tendons, allowing the body to repair the damaged tissues effectively.

D. Massaging the affected limb - Massaging the affected limb is generally not recommended in the acute phase of musculoskeletal injuries, especially contusions, strains, or sprains. Massaging can potentially worsen the injury, increase swelling, and cause further tissue damage. It is important to wait until the initial acute phase has passed and consult a healthcare professional before considering massage therapy.

E. Compression dressings - Compression helps control swelling by applying pressure to the injured area. Compression dressings or bandages provide support to the injured limb, minimize swelling, and reduce the risk of further injury. However, it's essential to apply compression correctly to avoid cutting off circulation, and it's usually best done under the guidance of a healthcare provider.
