CHAPTER Preventing Pressure Ulcers and Assisting …

1 431 Many of your patients or residents will be at risk for devel-oping Pressure Ulcers . Preventing Pressure Ulcers is amajor concern of the nursing team because pressureulcers are painful, hard to treat, and potentially fatal. In this CHAPTER ,you will learn about your role in Preventing Pressure Ulcers . Pressureulcers are just one type of wound you may see when you are caring forpatients and residents. In this CHAPTER , you will also learn about howthe health care team cares for people with wounds and your role inassisting the nurse with wound Pressure Ulcers andAssisting With Wound CareCHAPTER19A nursing assistantmakes an occupiedbed.

How Pressure Ulcers formMany patients and residents are not able to change position easily due to weakness,disability, or illness. This inability to change position without help places the personat high risk for developing a Pressure ulcer .

4 Pressure Ulcers form when pressurepointspress against a mattress, chair, or other surface (Fig. 19-1). The pressuresqueezes the tissues in between the bone and the surface the person is lying or sittingon. As a result, blood flow to the tissues decreases. The tissues do not receive enoughnutrients and oxygen, and they die. The dead tissue peels off or breaks open, creat-ing an open sore or ulcer . Pressure Ulcers develop in four stages (Box 19-1).The longer a person remains in one position, the more likely that person is todevelop a Pressure ulcer . Many people with limited mobility also have other riskfactors for developing a Pressure ulcer , such as: Old skin of an older person is fragile and thin, with less blood flow.

5 Poor nutrition and lack of skin to remain healthy, good nutritionand adequate fluid intake are essential. contact with water, urine, feces, or sweat causes the epi-dermis to soften and break down (leading to skin breakdown ). Cardiovascular or respiratory with cardiovascular or respira-tory problems are at high risk for developing Pressure Ulcers because their med-ical condition prevents their tissues from receiving the full amount of oxygenand nutrients. Friction and shearing (rubbing) and shearing (pulling) forcescan injure the skin and lead to skin breakdown. Friction and shearing forcesare described in more detail in CHAPTER the Omnibus Budget Reconciliation Act (OBRA), one of the crite-ria used to evaluate the quality of care given by long-term care facilities thatLWBK098-3855G-C19[431-445].

The nurse is responsible for assessing each resident srisk for developing Pressure Ulcers when the resident is admitted to the long-termcare facility. The nurse also documents any existing Pressure Ulcers . OBRA expectsthe health care team to maintain or improve the person s condition. This meansthat the health care team works to heal existing Pressure Ulcers and takes measuresto prevent new Pressure Ulcers from forming.

7 Nursing assistants help the healthcare team to achieve these goals by carefully following the person s care plan.

10 Report red, pale, white, orshiny areas over Pressure points right away. Provide good skin care. When bathing a person, cleanthe skin gently and thoroughly and rinse off the soapwell. Make sure the skin is dried well and use lotion tokeep the skin healthy and soft. Thoroughly clean anddry areas where skin touches skin, such as under thebreasts, and apply a light dusting of powder to keep theskin dry. Regular repositioning prevents any one part of the per-son s body from being under Pressure for too long. The bedpan places Pressure on the person s lower spine,one of the Pressure points. Redness over a Pressure point that does not go awayafter 5 minutes or an area over a Pressure point thatwas previously red but now is pale, white, or shiny couldbe a sign of a stage 1 Pressure ulcer .
