What are the classifications of wounds?
Wounds are classified based on their depth, cause, and severity, including categories like abrasions, lacerations, punctures, and surgical wounds.
124
What are the phases of wound healing?
The phases are the inflammatory phase, the proliferative phase, and the maturation phase.
125
What occurs during the inflammatory phase of wound healing?
This phase involves the initial response to injury, including redness, heat, swelling, and pain, as the body works to prevent infection and start healing.
126
Describe the proliferative phase of wound healing.
In this phase, new tissue forms, including the development of granulation tissue and re-epithelialization, as the wound fills in and the edges start to close.
127
What happens during the maturation phase of wound healing?
The wound undergoes remodeling where the new tissue gains strength and elasticity, and the scar matures and becomes less prominent.
128
What are the three types of wound healing?
The three types are primary intention (healing with minimal scarring), secondary intention (healing by granulation), and tertiary intention (delayed closure).
129
Name some local factors that may affect wound healing.
Local factors include infection, tissue necrosis, and poor blood supply.
130
What are some systemic factors that can impact wound healing?
Systemic factors include diabetes, malnutrition, and chronic illnesses.
131
How do acute wounds differ from chronic wounds?
Acute wounds heal in a predictable time frame and typically without complications, whereas chronic wounds fail to progress through the normal phases of healing and persist longer.
132
What does the mnemonic "TIME" stand for in wound management?
"T" stands for Tissue management, "I" for Inflammation control, "M" for Moisture balance, and "E" for Edge advancement.
133
Why is moist wound healing important?
Moist wound healing promotes faster healing, reduces pain, and minimizes scarring by creating an optimal environment for cell migration and tissue repair.
134
What types of dressing products promote moist wound healing?
Dressing products that promote moist wound healing include hydrocolloids, hydrogels, and foam dressings.
135
Differentiate between an ileostomy, colostomy, and urostomy.
An ileostomy diverts the small intestine to the outside of the body, a colostomy diverts the large intestine, and a urostomy diverts urine from the urinary tract.
136
What is involved in the care of a stoma?
Stoma care involves regularly changing the appliance, cleaning the stoma site, and monitoring for any signs of complications or irritation.
137
What is the definition of a wound?
A wound is a break or disruption in the normal integrity of the skin and underlying tissues.
138
What are surgical wounds?
Surgical wounds are planned and intentional, resulting from invasive procedures like surgeries.
139
How do non-surgical wounds differ from surgical wounds?
Non-surgical wounds are unexpected and often result from trauma, whereas surgical wounds are planned and intentional.
140
What is the primary difference between acute and chronic wounds based on healing time?
Acute wounds generally heal within six weeks, while chronic wounds take longer than three months to heal.
141
What are partial thickness wounds?
Partial thickness wounds affect the entire epidermis but may leave parts of the dermis intact.

What is a fungating breast cancer wound?
A fungating breast cancer wound is a type of chronic wound where the focus is on managing appearance, controlling pain, and maintaining patient comfort rather than healing.
146
What causes pressure ulcers?
Pressure ulcers result from prolonged pressure on areas of the body, often in immobile patients, leading to decreased blood supply and tissue damage.
147
What is the significance of wound classification for nurses and midwives?
Wound classification helps in effectively communicating about a patient’s progress and response to treatment.
148
How are wounds classified based on cleanliness?
Wounds can be classified as clean, clean-contaminated, contaminated, or dirty/infected based on the risk of bacterial contamination.
149
What characterizes a clean-contaminated wound?
A clean-contaminated wound is intentional, involving entry into the respiratory, gastrointestinal (GI), or genitourinary (GU) tracts, but the procedure is done under sterile conditions.
150
What is a contaminated wound?
A contaminated wound includes open traumatic wounds or intentional wounds where sterile technique was compromised.
151
What are dirty/infected wounds?
Dirty/infected wounds are traumatic wounds with dead tissue or intentional wounds with pre-existing infection.

The inflammatory phase lasts about three to six days.
156
What processes occur during the hemostasis phase of wound healing?
Hemostasis involves blood clotting to stop bleeding.
157
What happens during the inflammation phase?
During inflammation, blood vessels dilate, increasing capillary permeability to allow plasma and blood components to leak into the injured area, causing swelling, mild temperature elevation, and pain.
158
What role do white blood cells play in the inflammatory phase?
White blood cells move to the wound to ingest bacteria and cellular debris.
159
When does the proliferative phase begin, and how long does it last?
The proliferative phase begins around day two or three and lasts for about two to three weeks.
160
What occurs during the proliferative phase of wound healing?
Granulation tissue forms, wound closure begins, and new tissue is built to fill the wound space through fibroblasts secreting collagen and growing capillaries.
161
What is the duration of the maturation phase, and what happens during this phase?
The maturation phase begins around day 21 and can last for six to 12 months or longer, during which collagen remodeling increases the strength of the injured area, and the scar becomes avascular.
162
What percentage of its original strength does the tissue generally regain after the maturation phase?
The tissue generally regains about 70% of its original strength.
163
How do acute wounds progress through the phases of healing?
Acute wounds follow the normal wound healing process through the inflammatory, proliferative, and maturation phases.
164
What characterizes chronic wounds in terms of healing phases?
Chronic wounds get stuck in the inflammatory phase and cannot progress through the normal stages of wound healing.
165
What is the management goal for chronic wounds?
The goal is to restore normal wound healing physiology by promoting progression through the inflammatory, proliferative, and maturation phases.
166
How do malignant wounds differ from chronic wounds in terms of healing?
Malignant wounds generally do not heal and changes in tissue can prevent closure, whereas chronic wounds might still progress through healing phases with proper management.
167
Why is it important to educate patients on wound care before discharge?
Educating patients is crucial to prevent breakdown of the wound area and to manage the area properly to avoid further damage.
168
What is primary intention healing?
Primary intention healing occurs in surgical wounds with minimal tissue loss, where the wound edges can be easily brought together and closed with sutures, staples, or sterile strips, resulting in a clean wound with a small scar.
169
When is secondary intention healing used?
Secondary intention healing is used for wounds with significant tissue loss where the edges cannot be brought together, and healing occurs from the base upwards through granulation, leading to larger scars.
170
What distinguishes tertiary intention healing from primary and secondary intention healing?
Tertiary intention healing involves leaving the wound open for a period to allow drainage of infection or reduction of swelling before the wound edges are brought together for closure.
171
How does the healing process differ in primary intention compared to secondary intention?
In primary intention, the wound edges are approximated and closed with sutures or staples, leading to a small scar. In secondary intention, the wound heals from the base upwards through granulation, resulting in larger scars due to significant tissue loss.
172
Why might tertiary intention healing be chosen for a wound?
Tertiary intention healing is chosen to manage infection or swelling by keeping the wound open temporarily, allowing for proper drainage before closing the wound.
173
What type of wound healing is characterized by the formation of new vascular tissue?
Secondary intention healing is characterized by the formation of new vascular tissue as the wound heals from the base upwards through granulation.
174
Give an example of a situation where tertiary intention healing would be appropriate.
An example of tertiary intention healing is an open abdomen with gauze and dressing to manage drainage until inflammation subsides, after which the wound can be closed.
175
What is a key feature of wounds healed by primary intention?
Wounds healed by primary intention have clean, well-approximated edges with minimal tissue loss, resulting in a small scar.
176
What is a common result of wounds healed by secondary intention?
Wounds healed by secondary intention often result in larger scars due to significant tissue loss and healing through granulation and epithelialization.
177
How long is a wound typically left open during tertiary intention healing?
A wound is typically left open for 3 to 5 days during tertiary intention healing to allow for infection drainage or reduction of swelling before closure.
178
What effect does infection have on wound healing?
Infection can delay wound healing by causing the wound to remain stuck in the inflammatory phase, as bacteria produce toxins that interfere with healing and may cause cell death.
179
How does maceration impact wound healing?
Maceration, or overhydration of the wound, can change the pH of the skin, leading to bacterial overgrowth and skin erosion, which can cause the wound to break down and increase in size.
180
What is the impact of edema on wound healing?
Edema reduces blood flow to the area by increasing excess fluid in the interstitial space, which decreases the oxygen supply needed for cellular repair and division.
181
How does necrosis affect wound healing?
Necrotic tissue, which can appear yellow, sloughy, or black and leathery, prevents wound closure and impedes the healing process.
182
What are some local factors that can affect wound healing?
Local factors include infection, maceration, edema, necrosis, foreign bodies, pressure, and trauma to the wound site.
183
How does age affect wound healing?
Older adults often experience delayed wound healing due to chronic illnesses, age-related changes such as decreased mobility, and reduced blood supply to the wound.
184
Why is oxygenation and circulation important for wound healing?
Adequate blood flow and oxygen are crucial for wound healing as they supply the necessary nutrients and oxygen needed for tissue repair.
185
How does nutritional status impact wound healing?
Malnourished individuals or those lacking essential nutrients, such as zinc, vitamin A, and vitamin C, often experience delayed wound healing because these nutrients are vital for collagen formation and wound repair.
186
What role do medications play in wound healing?
Certain medications, such as chemotherapy, can delay wound healing by reducing cell proliferation and affecting the body's ability to repair wounds.
187
How does immunosuppression affect wound healing?

193
What does the TIME framework stand for?
The TIME framework stands for Tissue, Infection or Inflammation, Moisture Balance, and Edge of the Wound.
194
What should you assess regarding 'Tissue' in the TIME framework?
Assess the type of tissue present, including necrotic tissue, slough, and granulation tissue. Necrotic and slough tissues need removal, while granulation tissue indicates healthy wound progress.
195
How can necrotic tissue affect wound healing?
Necrotic tissue, which appears black or dark gray, prevents wound closure and must be removed for healing to progress.
196
What are signs of infection or inflammation to look for in a wound?
Signs include redness, warmth, pain, and any unusual discharge such as greenish or foul-smelling exudate.
197
How does moisture balance impact wound healing?
A wound should be kept moist but not overly wet or dry. Proper moisture balance promotes healing by allowing fibroblasts to migrate and helps minimize scarring.

Serous exudate, being thin and yellow, typically indicates a healing wound with low levels of protein.
201
What does purulent exudate suggest?
Purulent exudate indicates infection, containing pus, dead cells, and pathogens.
202
How can hemorrhagic exudate be identified and what does it indicate?
Hemorrhagic exudate is bright red and contains many red blood cells, indicating active bleeding.
203
Why is aseptic technique important in wound management?
Aseptic technique is crucial to reduce the risk of surgical site infections (SSI) and other hospital-acquired infections.
204
What are the key concepts of aseptic technique to follow?
Follow the clean and dirty area concept, where one hand or instrument is designated as clean and the other as dirty, and the wound field concept, which maintains a sterile area around the wound.
