Which skin condition occurs as an allergic reaction to mite eggs?

Correct Answer: A

Rationale: Rationale: The correct answer is A) Scabies. Scabies is a skin condition caused by an infestation of the human itch mite. This mite burrows into the skin to lay eggs, triggering an allergic reaction that leads to intense itching and a pimple-like rash. It is highly contagious and usually spreads through close physical contact. Option B) Impetigo is a bacterial skin infection, often characterized by honey-colored crusts on the skin. It is not caused by mites or related to an allergic reaction to mite eggs. Option C) Folliculitis is an inflammation of the hair follicles, usually caused by bacterial or fungal infections. It presents as red, swollen bumps or pustules around hair follicles. It is not associated with mite eggs. Option D) Pediculosis refers to an infestation of lice, not mites. Lice are parasitic insects that infest the hair and scalp, leading to intense itching. It does not involve mite eggs or an allergic reaction to them. Educational Context: Understanding skin conditions like scabies is crucial for healthcare professionals, especially those working in dermatology or primary care settings. Recognizing the symptoms of scabies, such as intense itching and a rash in characteristic locations like between fingers and on wrists, helps in accurate diagnosis and timely treatment. Educating patients about scabies transmission and prevention is also important to control outbreaks and prevent reinfection. Knowledge of various skin conditions and their distinguishing features is vital for healthcare providers to provide effective care and support to patients with dermatological issues.

Correct Answer: A

Rationale: Educational Rationale: Patient teaching for risk reduction of skin cancer is a crucial aspect of healthcare education. Option A, having suspicious moles checked by a dermatologist, is the correct choice because early detection of skin cancer greatly improves treatment outcomes. By regularly monitoring moles and seeking professional evaluation, individuals can catch potential issues early on. Option B, daily sun exposure every ½ hour, is incorrect as excessive sun exposure is a known risk factor for skin cancer. Encouraging frequent, unprotected sun exposure contradicts the goal of risk reduction. Option C, daily sun exposure of 1 hour to build tolerance, is also incorrect for the same reason. Option D, applying moisturizer, while important for skin health, is not directly related to skin cancer risk reduction. Although moisturizing can help maintain skin integrity, it does not address the primary preventive measure of monitoring and early detection of suspicious moles. In an educational context, emphasizing the importance of regular skin checks by a dermatologist, along with sun protection measures like wearing sunscreen and protective clothing, can empower individuals to take an active role in reducing their risk of skin cancer. By understanding the rationale behind these preventive measures, patients can make informed choices to safeguard their skin health.

Correct Answer: C

Rationale: The correct answer is C) Saline. Using saline to clean a wound is recommended because it is a gentle and effective way to remove debris and bacteria without damaging the surrounding tissues or causing further irritation. Saline solution is isotonic, meaning it has a similar concentration of salt and minerals as the body, which helps to promote healing and reduce the risk of infection. Option A) Hydrogen peroxide is not recommended for cleaning wounds as it can be too harsh on the tissues, leading to delayed wound healing and potential damage to healthy cells. The bubbling action can also disrupt the wound bed and impede the healing process. Option B) Tap water may contain impurities or chemicals that can be harmful if introduced into an open wound. It is not sterile like saline solution, which increases the risk of infection. Option D) Leaving a wound undisturbed can be appropriate in some cases, but it is essential to clean a wound to prevent infection and promote proper healing. Neglecting to clean a wound can lead to complications and prolong the healing process. Educationally, it is crucial to teach proper wound care techniques to promote optimal healing outcomes. Emphasizing the use of gentle, isotonic solutions like saline can help students understand the importance of maintaining a clean wound environment while minimizing tissue damage. Encouraging evidence-based practices in wound care will equip students with valuable skills to provide effective care in various healthcare settings.

Correct Answer: C

Rationale: The correct answer is C) the threat to his self-image. Psoriasis is a chronic skin condition that can have a significant impact on a person's physical appearance, leading to feelings of embarrassment, self-consciousness, and low self-esteem. The emotional impact of psoriasis often stems from the visible nature of the condition, which can result in social stigma and negative perceptions from others. This can lead to psychological distress and a diminished quality of life for individuals living with psoriasis. Option A) its effect on the central nervous system is incorrect because while psoriasis is an immune-mediated condition, its emotional impact is more closely tied to the psychological and social aspects rather than direct effects on the central nervous system. Option B) the effects of the drugs used to treat the psoriasis is incorrect because while some medications used to treat psoriasis may have side effects, the emotional impact primarily arises from the visibility of the skin condition itself rather than the treatment modalities. Option D) the fear of dying is incorrect as psoriasis is not a life-threatening condition, and the emotional impact typically revolves around the challenges of managing a chronic skin condition rather than fear of mortality. In an educational context, understanding the emotional impact of psoriasis is crucial for healthcare professionals working with patients with this condition. By recognizing the psychosocial challenges faced by individuals with psoriasis, healthcare providers can offer holistic care that addresses not only the physical symptoms but also the emotional well-being of the patient. This knowledge can help improve patient outcomes and overall quality of life for individuals living with psoriasis.

Correct Answer: A

Rationale: In the resuscitative phase of care for a patient like Mr. Aspen, monitoring urine output is crucial as it provides essential information about kidney function and fluid balance. This is important for assessing the effectiveness of resuscitation efforts and ensuring adequate organ perfusion. Option A is correct because in critically ill patients, maintaining adequate urine output is indicative of sufficient cardiac output and renal perfusion, which are essential for overall patient stability and recovery. Option B, pain level, while important, is not the most critical variable to monitor during the resuscitative phase. Pain management is crucial for patient comfort, but it does not directly impact physiological stability in the same way urine output does. Option C, central venous pressure, may provide information about fluid status, but it is not as reliable or immediate as monitoring urine output in assessing kidney function and fluid balance during resuscitation. Option D, progression of wound healing, is not a priority during the resuscitative phase when the focus is on stabilizing vital functions and ensuring organ perfusion. Educationally, this question highlights the importance of prioritizing key physiological parameters in the management of critically ill patients and underscores the significance of monitoring urine output as a vital sign in assessing fluid status and renal function.
