Patients at Risk- HESI Case Study (Evolve) correctly 2023

Sally makes ongoing rounds, recommending prevention strategies and treatments for a wide variety of wounds, including pressure ulcers. A pressure ulcer is a/an: - answer Localized area of tissue necrosis A pressure ulcer is a localized area of tissue necrosis (death), caused by ischemia associated with prolonged, unrelieved pressure. Unrelieved pressure causes ischemia (poor circulation) which deprives the affected area of oxygen and nutrients, potentially leading to necrosis. Pressure ulcers usually develop in areas where soft tissue capillaries are compressed between a bony area and an external surface. Both the intensity and duration of pressure are important contributors to pressure ulcer risk. Which of the following contribute to Mr. Esserman's risk for development of pressure ulcers? - answer Paralysis of arm and leg (Mr. Esserman's paralysis increases his risk for pressure ulcers. Any person who has limited ability to move himself and change position is at risk for developing a pressure ulcer. The person must rely on others to help move and change position to prevent pressure ulcer development. Also, Mr. Esserman sits in his favorite chair for most of the day. Being confined to a chair for a prolonged period of time can cause continuous unrelieved pressure on the same areas. This can lead to pressure ulcer development.) Loss of sensation (With loss of sensation, the normal ability of the nervous system to alert a person to "numbness" that happens after being in one position for too long is no longer present. Sensations of disco
