Which of the following are consequences of skin impairment?

Correct Answer: C

Rationale: The correct answer is C: Infection of the wound. Skin impairment can lead to an open wound, making it susceptible to bacterial invasion and infection. Bacteria can enter the wound, leading to inflammation and potential complications. Purulent leakage (choice A) is a symptom of infection, not a direct consequence of skin impairment. Itching (choice B) is a common symptom of skin irritation but not a direct consequence of skin impairment. Pain (choice D) can be a result of skin impairment but is not as directly linked to the consequences of an infected wound. Ultimately, infection of the wound is the most critical consequence of skin impairment due to the potential for serious complications and delayed healing.

Correct Answer: B

Rationale: The correct answer is B because growing cultured skin is indeed time-consuming. Cultured skin requires a significant amount of time for cells to proliferate and form a suitable skin graft. This process can take several weeks to months, thus delaying treatment for patients in need of immediate skin repair. A: Pigmentation mismatch is not a disadvantage as it can be managed with techniques like pigmentation matching. C: The risk of infection can be minimized through proper sterile techniques during the culturing process. D: The risk of rejection can be reduced by using the patient's own cells to grow the cultured skin, making rejection less likely.

Correct Answer: A

Rationale: The correct answer is A because malignant melanomas typically present as non-keratotic and soft lesions. Choice B is correct as melanomas arise from melanocytes. Choice C is correct as melanoma has a high mortality rate. Choice D is correct as melanomas often have irregular color and asymmetric shape.

Correct Answer: B

Rationale: The correct answer is B: Warty, irregular papules or plaques. Seborrheic keratosis is a common benign skin growth characterized by warty, raised, and often brown or black lesions. These growths have a stuck-on appearance and may be smooth or rough. They are not associated with white patchy yeast infections (choice A), excessive turnover of epithelial cells (choice C), or deep inflammation of subcutaneous tissue (choice D). The key characteristics of seborrheic keratosis are the warty and irregular nature of the lesions, which differentiate it from other skin conditions.

Correct Answer: A

Rationale: The correct answer is A: Warm oatmeal baths. Oatmeal has soothing properties and helps to soften scales and crusts, making it easier to remove them gently without causing further damage to the skin. The warm temperature of the bath also helps in loosening the scales. B: Warm saline dressings are more suitable for wound cleansing or promoting wound healing, not specifically for debridement of scales and crusts. C: Cool sodium bicarbonate baths may help with itching and inflammation but may not effectively promote the removal of scales and crusts. D: Cool magnesium sulfate dressings are more commonly used for wound healing and managing inflammation, not specifically for debridement of skin lesions.
