NUR 6001 EXAM 1 – ADVANCED HEALTH ASSESSMENT QUESTIONS COMPLETE WITH VERIFIED ANSWERS AND DETAILED RATIONALE 1. Which layer of the epidermis is found exclusively in thick skin areas such as palms and soles? A. Stratum corneum B. Stratum granulosum C. Stratum lucidum D. Stratum germinativum Answer: C. Stratum lucidum Expert Rationale: The stratum lucidum is a translucent, clear layer of the epidermis that is only present in thick skin, particularly on the palms of the hands and soles of the feet. This layer provides an extra barrier of protection in areas subjected to high friction and shear forces. Understanding this anatomical distinction is essential when assessing skin variations across different body regions. ________________________________________ 2. A patient presents with a skin lesion that is described as "confluent" in the medical record. What aspect of the lesion does this term describe? A. Morphology B. Color C. Distribution D. Texture Answer: C. Distribution Expert Rationale: "Confluent" describes the distribution pattern of lesions, indicating that they merge or run together to form larger areas of involvement. This is distinct from morphology (shape and structure), color, or texture. Accurate use of dermatologic terminology regarding distribution is essential for precise documentation and communication in advanced health assessment. ________________________________________ 3. Hair follicles are primarily anchored in which layer of the skin? A. Epidermis B. Subcutaneous layer C. Dermis D. Adipose tissue Answer: C. Dermis Expert Rationale: Hair follicles originate and are anchored within the dermis, where they receive vascular supply and are associated with sebaceous glands. The dermis provides structural support and nourishment for hair growth. Recognition of dermal structures is fundamental when evaluating wounds, inflammatory skin conditions, and hair disorders. ________________________________________ 4. A patient presents with erythematous plaques covered by silvery, keratinized scales. What is the most likely diagnosis? A. Eczema B. Psoriasis C. Acne vulgaris D. Discoid lupus erythematosus Answer: B. Psoriasis Expert Rationale: Psoriasis characteristically presents with well-demarcated erythematous plaques covered by thick, silvery-white scales resulting from rapid keratinocyte turnover. This presentation is distinct from eczematous lesions which typically show weeping or crusting, acneiform lesions which involve comedones, and discoid lupus which often shows scarring and dyspigmentation. ________________________________________ 5. To differentiate between granuloma annulare and a dermatophyte infection, which diagnostic procedure should be performed? A. Skin biopsy B. Wood's lamp examination C. Skin scraping with a 15-blade scalpel D. Patch testing Answer: C. Skin scraping with a 15-blade scalpel Expert Rationale: Skin scraping with a scalpel blade for potassium hydroxide (KOH) preparation is the standard method to identify dermatophyte infections by visualizing fungal hyphae. Granuloma annulare is a noninfectious granulomatous dermatosis that will not demonstrate fungal elements on scraping. This distinction is critical for appropriate treatment selection. ________________________________________ 6. A mature area on a patient's arm appears smooth, shiny, and lacks normal skin markings such as hair follicles and pores. This is most consistent with which finding? A. Psoriatic plaque B. Hypokeratinization C. Scar tissue D. Skin tag Answer: C. Scar tissue Expert Rationale: Mature scars typically appear smooth, shiny, and devoid of normal skin appendages including hair follicles, pores, and skin lines. This appearance results from the replacement of normal skin architecture with collagenous connective tissue. Differentiating scars from primary skin lesions is important for accurate dermatologic assessment. ________________________________________ 7. A patient presents with greasy, yellowish, adherent scales on coalescing macules along the eyebrows, scalp, and nasolabial folds. This presentation is most consistent with which form of dermatitis? A. Allergic contact dermatitis B. Seborrheic dermatitis C. Stasis dermatitis D. Atopic dermatitis Answer: B. Seborrheic dermatitis Expert Rationale: Seborrheic dermatitis classically affects sebaceous-rich areas including the scalp, eyebrows, nasolabial folds, and central chest with greasy, yellowish scales. This distribution and scale characteristic distinguish it from atopic dermatitis (typically flexural in children, extensor in infants), allergic contact dermatitis (exposure-related), and stasis dermatitis (lower extremity venous insufficiency). ________________________________________ 8. Which of the following skin lesions commonly appears on the head or face? A. Verruca vulgaris B. Dermatofibroma C. Neurofibroma D. Actinic keratosis Answer: C. Neurofibroma Expert Rationale: Neurofibromas can appear on the head, face, and trunk, either as solitary lesions or as multiple lesions in neurofibromatosis. While actinic keratoses also commonly occur on sun-exposed areas of the face, neurofibroma is the characteristic lesion identified for this presentation in dermatologic assessment. ________________________________________ 9. Which of the following skin conditions is considered premalignant? A. Actinic keratosis B. Paget's disease C. Lipoma D. Granuloma annulare Answer: A. Actinic keratosis Expert Rationale: Actinic keratoses are premalignant epidermal lesions resulting from cumulative sun exposure that have the potential to progress to squamous cell carcinoma if left untreated.
