Integumentary System Multiple Choice Questions and Answers Questions
Question 1 of 5
Keratinocyte is to epidermis as ___ is to dermis.
Correct Answer: A
Rationale: The correct answer is A: fibroblast. Keratinocytes are the predominant cells in the epidermis responsible for producing keratin, a protein that provides structural support and protection to the skin. Similarly, fibroblasts are the main cells in the dermis that produce collagen and elastin fibers, which give the skin its strength and elasticity. Fibrocytes (choice C) are inactive fibroblasts, and dermoblasts (choice B) and dermocytes (choice D) are not recognized cell types in dermatology. Therefore, fibroblast is the most appropriate analogy for the relationship between keratinocyte and epidermis.
Question 2 of 5
A 20-year-old patient is being seen in the dermatology clinic for a basal cell carcinoma on her eye. The nurse would expect the physician to complete which intervention?
Correct Answer: B
Rationale: The correct answer is B: Mohs' micrographic surgery. This technique is preferred for basal cell carcinoma on sensitive areas like the eye because it allows for precise removal of cancerous tissue layer by layer while sparing healthy tissue. It offers the highest cure rate and best cosmetic outcome. Electrosurgery (A) may not be as precise, Cryosurgery (C) is not ideal for tumors on the eye, and Radiation (D) is typically reserved for cases where surgery is not feasible.
Question 3 of 5
A patient with severe burn injuries to the abdomen and legs becomes combative when it is time to change the dressings. What nursing intervention will be most helpful to this patient?
Correct Answer: B
Rationale: The correct answer is B because premedicating the patient with pain and anxiety medications before the dressing change can help decrease their discomfort and anxiety, making the process more tolerable. This intervention promotes patient comfort and cooperation, ensuring a successful and safe dressing change. Allowing the patient to determine the time of dressing change (A) may not address the underlying issue of anxiety and may lead to delays in care. Telling the patient it is okay to cry during the dressing change (C) does not actively address the patient's discomfort and may not be sufficient in managing their distress. Explaining the importance of dressing changes (D) may be helpful in some situations but may not directly address the patient's immediate need for pain and anxiety relief during the procedure.
Question 4 of 5
Which manifestation is characterized by eczematous eruptions with well-defined geometric margins?
Correct Answer: C
Rationale: The correct answer is C: Contact dermatitis. Contact dermatitis is characterized by eczematous eruptions with well-defined geometric margins due to direct contact with an irritant or allergen. Choice A is incorrect as drug eruptions typically present with bright red erythematous macules and papules. Choice B describes atopic dermatitis, which presents with lichenification, scaling, and excoriation. Choice D, nonspecific eczematous dermatitis, is a general term and does not specify the well-defined geometric margins seen in contact dermatitis.
Question 5 of 5
Which information would a nurse consider when planning care for a client with scabies?
Correct Answer: A
Rationale: Correct Answer: A (Highly contagious) Rationale: 1. Scabies is a highly contagious skin infestation caused by mites. 2. Understanding its contagious nature is crucial to prevent spread. 3. Isolation precautions and treatment of close contacts are essential. 4. Recognizing and addressing the contagious aspect is key in planning care. Summary: B: Scabies is caused by mites, not a fungus. C: Scabies is an acute condition with intense itching, not chronic. D: Scabies is not typically associated with other allergies.
