Week #4 (2026): 13-Year-Old Female With Pruritic
Skin Complaint – Comprehensive Clinical
Reasoning Guide With Full Patient Interview, ROS,
Focused Physical Exam, Differential Diagnoses,
Laboratory Evaluation
, PART 1: INITAL CLINICAL ENCOUNTER & DATA GATHERING
Opening the Encounter
Provider: "Good morning. My name is Dr. Chen, and I'm a nurse practitioner. I see you're here
because of some skin issues. Tell me what's been going on."
Emma: (fidgeting, occasionally scratching her arms) "My skin is just so itchy. Like, all the time. It's
really annoying and it's keeping me awake at night."
Provider: "I'm sorry to hear that. Itching that disrupts sleep is really tough, especially at your age
with school and everything. Before we dive into the details, I want to let you know that I'll be
asking you some questions, and also your mom, since she knows your health history. Emma, I'll
be directing most of the questions to you, since you're the expert on how you feel. Is that okay?"
Emma: "Yeah, that's fine."
Clinical Reasoning: The provider establishes rapport, validates the patient's experience, and sets
clear expectations about who will answer questions. Addressing the adolescent directly respects
her growing autonomy while still involving the parent appropriately.
PART 2: HISTORY OF PRESENT ILLNESS (HPI) – GRADUATE-LEVEL PROBING
Provider: "Emma, tell me more about this itching. When did it first start?"
Emma: "Maybe like a month ago? It started here, on the insides of my elbows." (points to
antecubital fossae)
Provider: "And since then, has it spread to other areas?"
Emma: "Yeah, now it's behind my knees, on my neck, and my wrists. Sometimes my stomach
itches too, but not as bad."
Provider: "When you say 'itchy,' describe it for me. Is it a surface itch, or does it feel deep? Does it
burn or sting at all?"
Emma: "It's just itchy. Like I need to scratch it. It doesn't burn. Sometimes after I scratch a lot, it
stings a little because I've made it raw."
Clinical Reasoning: The provider is assessing for neuropathic vs. inflammatory vs. dermatologic
causes. Burning or stinging might suggest neuropathic pain or contact dermatitis, while pure
pruritus is more consistent with atopic conditions.
