URGENT FINDING
UNIT 2
Areas of ecchymosis are often signs of trauma that could be the result of physical abuse, but are often presented as resulting from an injury or ‘clumsiness’ from the consumer. Ecchymotic areas at the base of the skull or on the face, buttocks, breasts or abdomen should warrant a high index of suspicion for abuse, especially if found in children or pregnant women, as should burns (e.g. cigarettes, iron) and belt buckle or bite marks. In addition, lacerations, scars, haematomas and puncture wounds should carry a high index of suspicion. Patterned injuries, such as those caused by ropes or chains, need to be investigated further.
Signs of physical abuse can also be present in the hair. Hair that is singed or unusually kinked may have been exposed to re. Alopecia can be caused by repeated pulling. Describe injuries in relation to type, age (old/new) and anatomical location.
Any signs of abuse should be investigated further and referred as necessary. Check your responsibilities for mandatory reporting with your state/territory or federal law. Further information relating to investigating possible abuse can be found in Chapter 3.
Bleeding, ecchymosis and vascularity

Inspect the skin for evidence of bleeding, ecchymosis or increased vascularity.
N
Normally, there are no areas of increased vascularity, ecchymosis or bleeding.

Bleeding from the mucous membranes, previous venipuncture sites or lesions should be considered abnormal.

Ecchymosis is caused by extravasation of blood into the skin as a result of trauma; it can also occur with heparin or warfarin use or liver dysfunction.
An erythematous dilation of small blood vessels is abnormal (see Figure 8.6D).

P
This erythematous dilation describes a telangiectasia. Erythematous dilations tend to appear on the face and thighs; they occur more frequently in women.
Spider angiomas are bright red and star-shaped (see Figure 8.6E). There is often

These ndings can indicate different stages of necrosis, or tissue death. Conditions that starve the affected body part of oxygen, whether in acute or chronic situations, can cause necrosis. Diabetes mellitus, disseminated intravascular coagulation, acute hypovolaemia, and severe electric charge are some of the conditions that can cause necrosis.

P
Gas gangrene, or clostridial myonecrosis, is a Gram-positive infection that affects skeletal muscles that have decreased oxygenation. The clostridia organisms are endogenous to the gastrointestinal tract and are also found in the soil. Consumers who experience circulatory compromise, such as in diabetes mellitus, arterial insufciency, trauma and constricting casts, are at risk for developing gas gangrene. Consumers who have contaminated wounds and decreased vascularity to the affected area are also at risk for developing gas gangrene.
HEALTH EDUCATION
Evaluating skin lesions
A simple approach to teaching people how to decide to seek medical review for skin lesions is an essential tool for nurses. The following ABCDE mnemonic for evaluating skin lesions is easy to remember.
> A (Asymmetrical): Is the lesion asymmetrical? > B (Borders): Are the borders of the lesion irregular? > C (Colour): Is the colour of the lesion uneven, irregular or multicoloured? > D (Diameter): Has the lesion’s diameter changed recently? > E (Elevation): Has the lesion become elevated?
If the answer is ‘yes’ to any of the questions in this evaluation, consumers should be referred to or advised to go to their medical ofcer or skin lesion/cancer clinic for further assessment.
CHAPTER 8
Lesions
E
1. Inspect the skin for lesions, noting the anatomic location. Lesions can be
localised, regionalised or generalised. They can involve exposed areas or skin folds (see
2. Note the grouping or arrangement of the lesions: discrete, grouped,
conuent, linear, annular, polycyclic, generalised or zosteriform (see
3. Inspect the lesions for elevation (at or raised).
4. Using a ruler, measure the lesions.
5. Describe the colour of the lesions.
6. Note any exudate for colour or odour.
7. Note the morphology of the skin lesions. Skin lesions can be primary,
originating from previously normal skin, or secondary, originating from primary lesions. For specic descriptions of primary lesion morphology, see
Figure 8.8. For specic descriptions of secondary lesion morphology, refer to Figure 8.9.

CLINICAL REASONING
Practice tip: Wound evaluation
If a wound is present, the following assessment process should be undertaken (Benbow,
2016). Assess:
1. the person (examine all areas of the skin for signs of scarring, dermatological disorders,
skin changes, condition of skin, nails and hair of the extremities, skin colour temperature, pulse, capillary rell and oedema)
2. the region around the wound
3. the current dressing (type, condition, time since last changed)
4. exudate (colour, amount, odour)
5. wound base and edge (measure the borders of the wound with a centimetre ruler)
6. periwound skin
7. management of the wound to date, knowledge levels and related problems.
Draw a picture in your notes to depict necrotic areas, drains and other features.
Describe location in relation to anatomical landmarks.
Wound assessment should take a holistic, person-centred view. A useful framework to
undertake this is the 9 Cs of wound care (Baranoski, Ayello & Langemo, 2008):
> Cause of the wound > Clear picture of what the wound looks like > Comprehensive picture of the consumer > Contributing factors > Communication with other healthcare practitioners > Continuity of care > Centralised location for wound care information > Components of the wound care plan > Complications of the wound.

CLINICAL REASONING
Practice tip: MRSA infections
The incidence of skin and soft tissue infections caused by methicillin-resistant Staphylococcus aureus (MRSA) has signicantly increased in the outpatient population (called Community-Associated MRSA). MRSA is carried by approximately 30% of the population (either on their skin or in their nose or mouth), and is often not a problem for healthy people (Turnidge, Coombs, Daley, Nimmo & Australian Group of Antimicrobial Resistance (AGAR) participants, 2000–14, 2016). However, in some circumstances, it has the ability to cause outbreaks of infection that can cause serious poor health outcomes or worse. Deaths due to MRSA infections have occurred in young and old alike (Turnidge et al., 2016).
Risk factors are close living quarters (e.g. childcare centres, sporting groups, military barracks, dormitories, prisons and other institutions) and poor hygiene (e.g. sharing towels, bedsheets, sports equipment, handling soiled clothes and other personal items, and skin contact).
All suspect lesions or wounds need to be cultured for MRSA. MRSA is a notiable condition required to be reported by doctors, hospitals and laboratory technicians. Reporting is condential.
