A school nurse is assessing a child who has honey-colored crusted lesions around their mouth and on their arms. The nurse should recognize this as a characteristic of which of the following skis infections?
Impetigo
Scabies
Herpes simplex virus
Tinea corporis
The Correct Answer is A
A. Impetigo. Impetigo is a highly contagious bacterial skin infection, often caused by Staphylococcus aureus or Streptococcus pyogenes. It is characterized by honey-colored crusted lesions, especially around the mouth and extremities.
B. Scabies. Scabies presents as intensely itchy burrows or papules, often in the web spaces of the fingers, wrists, and axillae, rather than honey-colored crusts.
C. Herpes simplex virus. Herpes simplex virus (HSV) typically causes grouped vesicular lesions on an erythematous base, not crusted honey-colored lesions.
D. Tinea corporis. Tinea corporis (ringworm) presents as red, scaly, annular lesions with central clearing, not honey-colored crusts.

Correct Answer is B
Explanation
A. A rapidly growing, irregular brown lesion with uneven borders. This description is more characteristic of melanoma, which presents as an asymmetrical, dark lesion with irregular borders and rapid growth.
B. A slow-growing, pearly or waxy nodule with visible blood vessels with central ulceration. BCC typically appears as a pearly, waxy nodule with visible telangiectasia (small blood vessels). It grows slowly and may develop a central ulceration over time.
C. A dark, flat lesion with a satellite pattern of spreading pigmentation. This description aligns more with melanoma, which often spreads in a radial pattern with satellite lesions.
D. A firm, scaly lesion with a rough, honey-crusted surface. This description is more consistent with squamous cell carcinoma (SCC), which presents as a rough, scaly lesion that may ulcerate.
Correct Answer is D
Explanation
A. Nausea and vomiting after eating fatty foods: This symptom is more commonly associated with gallbladder disease (e.g., cholecystitis) rather than TB.
B. Sudden high fever and chills with a rash: TB typically causes a low-grade fever, night sweats, and progressive weight loss rather than sudden high fevers with a rash, which are more indicative of systemic infections like meningococcemia or viral exanthems.
C. Wheezing and shortness of breath that improves with bronchodilators: While TB can cause respiratory symptoms, it does not typically present with reversible airway constriction like asthma or chronic obstructive pulmonary disease (COPD), which respond to bronchodilators.
D. Productive cough with blood (hemoptysis): Hemoptysis (coughing up blood) is a hallmark symptom of active TB, resulting from lung tissue damage caused by the Mycobacterium tuberculosis infection.
