As your largest, fastest-growing, and most exposed organ, your skin forms a vital protective barrier that safeguards you from infection, regulates your body temperature, and helps facilitate your sense of touch. Your skin is inherently strong, but it’s also vulnerable to injury — sufficient pressure or friction can easily result in a scratch, abrasion, laceration, or some other painful wound. Luckily, your skin is remarkably resilient, too, in that it can repair most wounds and heal itself without much external support. Although wound healing is a relatively straightforward process, it can be accelerated, slowed, or otherwise influenced by a variety of factors. Here’s what you need to know about the stages of healing, and why some wounds may take longer to improve than others. Wound healing basicsWounds go through three specific stages as they progress through the healing process: InflammationDuring the inflammatory phase of healing, your body’s corrective mechanisms form a clot to stop any bleeding, then stimulate nearby blood vessels to flood the area with reparative and regenerative cells like growth factors, enzymes, white blood cells, and antibodies. ProliferationOnce initial inflammation subsides, your body enters the second stage of healing: proliferation. During this phase, the wound contracts as your body builds a new network of blood vessels to ensure the area receives enough oxygen and nutrients to support the growth of new, healthy tissues. MaturationThe final stage of healing, maturation, occurs when tissue regrowth has advanced far enough to prompt wound “resurfacing” with fresh skin cells. Once the surface area is strong, scabs fall away to reveal tighter, newer skin layers that may continue to remodel and rebuild for a year or longer. Wound healing progressionThe type, size, and severity of a wound can affect how quickly it heals — shallow cuts heal more quickly than deep lacerations, clean wounds heal faster than infected ones, and linear wounds tend to improve more quickly than round ones. A wide range of external physiological factors can also affect wound-healing progression, prolonging or even impeding the process altogether. Five of the most significant factors are: 1. Advanced ageAs you get older, hormonal changes and the cumulative effects of photoaging (sun damage) combine to leave your skin drier, thinner, more delicate, and less elastic. Besides leaving your skin more susceptible to injury, these age-related changes can substantially slow the healing process; older tissues simply don’t repair and regenerate as quickly as younger tissues. 2. Excess body weightPeople who are very overweight or obese are more likely to experience delayed wound healing as well as wound complications, including infection. Being overweight places more pressure on the wound itself, effectively decreasing the amount of nutrients and oxygen it receives to fuel the healing process. Wounds that occur within skin folds also tend to heal more slowly due to continuous friction and tissue breakdown. 3. Chronic illnessChronic conditions are a major factor in impaired wound healing for many people. Although the mechanisms at play tend to be numerous and varied, most persistent illnesses delay healing by interfering with one or more aspects of the immune system response. Diabetes can slow the healing process by making white blood cells less effective. Diabetes, cardiovascular disease, and other conditions that give rise to poor circulation may also make it harder for your body to deliver oxygen, nutrients, and reparative cells to an injured area. 4. Poor nutritionOptimal wound healing requires optimal nutritional support. People who eat an unhealthy diet that doesn’t meet their basic nutritional needs are more likely to experience the kind of slow or delayed healing that can lead to chronic wounds or injuries that take longer than three months to heal completely. 5. Unhealthy habitsPeople who smoke cigarettes and drink alcohol are more likely to experience slower healing rates than those who don’t smoke or drink. Both habits inhibit wound healing by suppressing your body’s inflammatory response and restricting the flow of blood, oxygen, nutrients, and reparative cells to the injured area.

Which of the following stimulates the wound healing process?Hypoxia stimulates wound healing such as the release of growth factors and angiogenesis, while oxygen is needed to sustain the healing process (Bishop, 2008).
Which action would the nurse take to decrease the risk of transmission of VRE?Doctors, nurses, and other healthcare professionals should: ➢ Wash their hands thoroughly with soap and water or use an alcohol based hand sanitizer before and after caring for every patient. This will prevent the spread of VRE from being passed from patient to patient.
Which reported clinical manifestations would the nurse expect from a client with ulcerative colitis?They include diarrhea, weight loss, abdominal cramping, anemia, and blood or pus in bowel movements. There's no cure for ulcerative colitis.
Which reason does the nurse give when instructing the client to take pyridostigmine about 1 hour before meals?The answer is C. Pyridostigmine is an anticholinesterase medication that will help improve muscle strength. It is important the patient has maximum muscle strength while eating for the chewing and swallowing process.
