A client is admitted to the floor and has symptoms of nausea, vomiting, and diarrhea as well as immobility due to a fractured femur. Which of the following are risk factors for pressure ulcers in this client?

Correct Answer: A

Rationale: In this scenario, the correct answer is A) Dehydration. Dehydration is a significant risk factor for pressure ulcers because it can lead to reduced blood flow to the skin, making it more susceptible to damage and slower wound healing. In a client with symptoms of nausea, vomiting, diarrhea, and immobility, dehydration is a common occurrence due to fluid loss and decreased intake. Proper hydration is crucial for maintaining skin integrity and preventing pressure ulcers. Option B) Hypokalemia is not directly linked to pressure ulcer development. While electrolyte imbalances can impact overall health, they do not have a direct correlation to skin breakdown. Option C) Hypernatremia, an excess of sodium in the blood, is not a common risk factor for pressure ulcers. It is more related to fluid balance and can lead to dehydration, which is a risk factor for pressure ulcers. Option D) Fluid overload is also not a typical risk factor for pressure ulcers. While excessive fluid retention can cause swelling and affect circulation, leading to other health issues, it is not a primary risk factor for pressure ulcer development. Educationally, understanding the relationship between hydration status and pressure ulcer risk is crucial for healthcare professionals caring for immobile patients. By recognizing dehydration as a risk factor, healthcare providers can implement preventive measures such as regular skin assessments, repositioning schedules, and adequate hydration protocols to reduce the incidence of pressure ulcers in vulnerable patients.

Correct Answer: C

Rationale: The correct answer is C) Epidermis, dermis, subcutaneous tissue, fat, fascia, muscle, and bone. In a fourth-degree burn, all layers of the skin (epidermis, dermis, subcutaneous tissue) are destroyed, extending to deeper tissues like fat, fascia, muscle, and even bone. This level of tissue involvement results in significant damage and potential complications like tissue necrosis and loss of function. Option A (Epidermis, dermis, subcutaneous tissue) describes a third-degree burn, not a fourth-degree burn. Option B (Deeper layer of the dermis with damage to sweat and sebaceous glands) is more characteristic of a second-degree burn. Option D (Epidermis and dermis, hair follicles intact) is indicative of a first-degree burn, where only the superficial layers of the skin are affected. Understanding the depth of burns is crucial in healthcare, as it guides treatment decisions, predicts outcomes, and influences patient management. Educating healthcare professionals on burn classifications helps them provide appropriate care, prevent complications, and promote optimal healing for patients with burn injuries.

Correct Answer: D

Rationale: The correct answer is D) Lesion has irregular color and asymmetric shape. Dysplastic nevus syndrome is characterized by atypical moles that exhibit irregular coloration, asymmetry in shape, and uneven borders. These moles are considered precursors to melanoma, a type of skin cancer. Understanding this characteristic is crucial in identifying potential early signs of melanoma and differentiating them from common moles. Option A) Associated with sun exposure is incorrect because dysplastic nevus syndrome is not primarily linked to sun exposure but rather to genetic factors. Option B) Precursor of squamous cell carcinoma is incorrect as dysplastic nevus syndrome is specifically associated with an increased risk of melanoma, not squamous cell carcinoma. Option C) Slow-growing tumor with rare metastasis is incorrect as dysplastic nevi are not typically slow-growing tumors; they are more concerning due to their potential to progress into melanoma, which can metastasize. Educationally, recognizing the features of dysplastic nevi is essential for healthcare professionals, particularly dermatologists and primary care providers, in conducting skin assessments, detecting early signs of melanoma, and advising patients on skin cancer prevention strategies like sun protection and regular skin checks. This knowledge can ultimately lead to early diagnosis and improved outcomes for individuals at risk for skin cancer.

Correct Answer: B

Rationale: In the context of educating about the integumentary system and urticaria, the correct answer is B) Avoid contact with the causative agent. Urticaria, commonly known as hives, is often triggered by allergens or irritants. Instructing the patient to avoid contact with the causative agent is crucial in preventing or minimizing the occurrence of urticaria. This strategy addresses the root cause of the condition and helps in symptom management. Option A) Apply topical benzene hexachloride is incorrect because benzene hexachloride is a pesticide and toxic compound that should not be applied to the skin, especially in the case of urticaria where skin sensitivity is common. Option C) Gradually expose the area to increasing amounts of sunlight is incorrect as sunlight exposure can actually trigger or worsen urticaria in many individuals due to its potential to aggravate skin inflammation. Option D) Use over-the-counter antihistamines routinely to prevent the condition is incorrect because while antihistamines can help alleviate symptoms of urticaria, they are typically used for acute episodes rather than for prevention. Relying solely on antihistamines for prevention may not address the underlying cause of the condition. Educationally, understanding the importance of identifying and avoiding triggers in conditions like urticaria is essential for patients to effectively manage their symptoms and improve their quality of life. By providing accurate information and guidance on trigger avoidance, healthcare professionals can empower patients to take an active role in their skin health and overall well-being.

Correct Answer: A

Rationale: The correct answer is A) Improve self-image. Elective cosmetic surgery is most commonly requested by patients to enhance their self-image and boost their confidence. This procedure is chosen by individuals who want to alter a physical feature they are unhappy with, ultimately leading to a more positive self-perception. Option B) Remove deep acne scars is incorrect as this addresses a specific skin concern rather than a general desire to enhance self-image through elective cosmetic surgery. Option C) Lighten the skin in pigmentation problems is incorrect because it focuses on correcting a specific skin issue related to pigmentation, rather than a broad desire for cosmetic enhancement. Option D) Prevent skin changes associated with aging is incorrect as it pertains to anti-aging treatments rather than elective cosmetic surgery for self-image enhancement. In an educational context, understanding the underlying motivations for elective cosmetic surgery helps healthcare professionals provide appropriate support and guidance to patients considering such procedures. It is important to have open discussions with patients about their expectations, motivations, and potential risks involved in cosmetic surgery to ensure informed decision-making.
