5. Describe the relationship between wheals and allergic reactions.
Wheals are a sign of chronic skin conditions unrelated to allergies.

responses, commonly seen in conditions like urticaria.

6. Interpret the significance of identifying a wound as 'recalcitrant' in wound
management.
Identifying a wound as recalcitrant indicates that it requires
specialized treatment strategies.
Identifying a wound as recalcitrant implies it is healing normally.
Identifying a wound as recalcitrant suggests it is a minor injury.
Identifying a wound as recalcitrant means it will heal without
intervention.
7. Describe the significance of the skin's pH range in relation to wound healing.
The skin's pH range only affects cosmetic appearance.
The skin's pH range of 4 to 5.5 helps maintain a protective barrier
against pathogens and supports the healing process.
The skin's pH range is irrelevant to wound healing.
A higher pH range promotes faster healing.

Exactly 1 cm
, Greater than 1 cm
Greater than 2 cm
Less than 1 cm
13. Describe the significance of identifying tunneling in a wound assessment.
Identifying tunneling is crucial as it indicates the wound's
complexity and may affect healing.
Tunneling is not significant in wound assessment.
Tunneling only affects the appearance of the wound.
Tunneling is a sign of a superficial wound.
14. In a clinical scenario, if a patient presents with a wound showing fluctuance,
what would be the most appropriate next step in management?
Suture the wound immediately.
Ignore the fluctuance as it is not significant.
Perform a culture to identify the infection.
Apply a topical antibiotic and discharge the patient.
15. Describe the characteristics that define a plaque in dermatological terms.
A plaque is a raised, round lesion that is less than 1 cm.
A plaque is a flat, discolored area of skin that is larger than 2 cm.
A plaque is a superficial, flat-topped lesion that is greater than 1
cm.
A plaque is a deep, irregular lesion that can vary in size.
