All of the following are characteristics of the epidermis except that it

Correct Answer: A

Rationale: Correct Answer: A (is vascularized) Rationale: The epidermis is avascular, meaning it does not contain blood vessels. This is crucial for protection against external factors. The other choices are correct: B) It is multilayered to provide protection, C) It is flexible to allow for movement, and D) It is self-repairing to heal minor injuries. Summary: - A: Incorrect, as the epidermis lacks blood vessels for protection. - B: Correct, as the epidermis is multilayered for protection. - C: Correct, as the epidermis is flexible for movement. - D: Correct, as the epidermis has self-repairing capabilities.

Correct Answer: B

Rationale: The correct answer is B. The fair-skinned 55-year-old who has just had neck surgery and plans to walk outside is most at risk for sun exposure. Sunscreen is important to prevent skin damage and reduce the risk of skin cancer, especially for fair-skinned individuals who are more susceptible to sunburn and skin damage. A: Tetracycline can cause photosensitivity, but it is not the most concerning in this scenario. C: Dark-skinned individuals have more natural protection against UV rays, so sunscreen may not be as critical. D: Although the pruritic rash may be uncomfortable, it is not directly related to the need for sunscreen.

Correct Answer: A

Rationale: The correct answer is A because a patient with periorbital cellulitis requires close monitoring and immediate intervention due to the risk of complications such as vision loss or intracranial involvement. This assignment will provide the new graduate with an opportunity to develop critical thinking skills and prioritize care for a potentially unstable patient. Choice B is incorrect because a patient needing discharge instructions after skin grafts is usually stable and may not require acute interventions, making it less suitable for a new graduate. Choice C is incorrect because a dressing change for a stage 3 pressure ulcer post-hydrotherapy is a routine procedure that may not challenge the new graduate's critical thinking skills or require immediate interventions. Choice D is incorrect as teaching before a punch biopsy is important but not as time-sensitive or critical compared to managing a patient with periorbital cellulitis.

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: C

Rationale: The correct answer is C: Wash hands before and after applying a topical medication. This is crucial to prevent the spread of infection as proper hand hygiene reduces the risk of introducing harmful bacteria to the wound. Cold wet soaks (A) do not address hand hygiene and may not be effective in preventing infection. Proper disposal of soiled material (B) is important but not the most critical action for preventing infection. The use of an antiseptic solution (D) is helpful, but without proper hand hygiene, the risk of spreading infection remains high.
