Section 1: Clinical Reasoning and Diagnostic Process Across the Lifespan
Hypothesis Generation, Illness Scripts, & Diagnostic Errors | Q1 - Q28
Q1: A 42-year-old female presents with fatigue, weight gain, cold intolerance, and constipation for 3 months.
Which clinical reasoning process involves comparing the patient's presentation to patterns of known diseases to
generate a differential diagnosis?
A. Forward reasoning
B. Hypothetico-deductive reasoning
C. Pattern recognition (illness scripts) [CORRECT]
D. Heuristic reasoning
Correct Answer: C
Rationale: Pattern recognition, also called illness scripts or backward reasoning, involves comparing the patient's
presentation to mental models of diseases accumulated through clinical experience. The cluster of fatigue, weight gain, cold
intolerance, and constipation in a middle-aged woman matches the illness script for hypothyroidism. Forward reasoning
(option A) starts with data collection then generates hypotheses. Hypothetico-deductive reasoning (option B) generates
multiple hypotheses and tests them through additional data. Heuristics (option D) are mental shortcuts that can lead to bias.
Illness scripts develop with experience and include predisposing conditions, epidemiology, and disease prototypes.
Study Strategy: Illness scripts = pattern recognition based on clinical experience. Includes predisposing conditions, epidemiology,
pathophysiology, and disease prototypes. Develops with experience.
Q2: An NP student is evaluating a 55-year-old male with acute onset of severe tearing chest pain radiating to the
back, BP 180/110 in right arm and 145/95 in left arm. What is the PRIORITY diagnostic hypothesis?
A. Acute myocardial infarction
B. Aortic dissection [CORRECT]
C. Pulmonary embolism
D. Esophageal rupture
Correct Answer: B
Rationale: The presentation of severe tearing chest pain radiating to the back with a >20 mmHg BP differential between
arms is classic for aortic dissection — a surgical emergency. The BP differential indicates luminal compromise of the
subclavian artery. Acute MI (option A) typically presents with substernal pressure radiating to left arm/jaw, without BP
differential. PE (option C) presents with dyspnea, pleuritic chest pain, and hypoxia. Esophageal rupture (Boerhaave
syndrome, option D) follows vomiting. Immediate CT angiography of the chest is diagnostic. Mortality increases 1-2% per
hour without treatment.
Study Strategy: Tearing chest pain + BP differential >20 mmHg between arms + radiation to back = AORTIC DISSECTION until proven
otherwise. CT angiography STAT. Surgical emergency.

Q3: Which of the following best describes an illness script?
A. A standardized symptom checklist for diagnosing specific conditions
B. A mental model of a disease incorporating predisposing conditions, pathophysiology, and clinical presentation
[CORRECT]
C. A diagnostic algorithm published by a professional organization
D. A patient's narrative describing their illness experience
Correct Answer: B
Rationale: An illness script is a clinician's mental model of a disease that integrates: (1) predisposing conditions
(epidemiology, risk factors); (2) pathophysiology (the disease mechanism); (3) clinical presentation (signs, symptoms, typical
course). These scripts develop through clinical experience and allow rapid pattern recognition. Expert clinicians have rich,
detailed illness scripts that enable quick identification of common conditions and recognition of atypical presentations.
Novice clinicians have sparse scripts and rely more on analytic reasoning. Building illness scripts across primary care
conditions is essential for NR511 students.
Study Strategy: Illness scripts = mental models of disease. Components: predisposing conditions, pathophysiology, clinical
presentation. Expert clinicians have rich, detailed scripts enabling rapid pattern recognition.
Q4: A 35-year-old male presents with acute onset right lower quadrant abdominal pain, anorexia, nausea, and
low-grade fever. McBurney's point tenderness is present with rebound. What is the MOST appropriate PRIORITY
action?
A. Prescribe oral antibiotics and follow up in 48 hours
B. Order outpatient abdominal ultrasound for the next day
C. Send to the emergency department for surgical evaluation and CT abdomen [CORRECT]
D. Prescribe antispasmodics and recommend dietary changes
Correct Answer: C
Rationale: The presentation is classic for acute appendicitis. McBurney's point tenderness with rebound, anorexia, nausea,
and fever in a young male has high positive predictive value. Priority is emergency department referral for surgical
evaluation and CT imaging. Delayed diagnosis risks perforation, peritonitis, sepsis, and death. Outpatient antibiotics (option
A) or delayed imaging (option B) are inappropriate for suspected acute appendicitis. Antispasmodics (option D) miss a
surgical emergency. Alvarado score ≥7 supports the diagnosis. Surgical appendectomy is definitive treatment.
Study Strategy: Acute RLQ pain + anorexia + McBurney point tenderness + rebound + fever = appendicitis. ED referral STAT for CT →
surgery. Alvarado score ≥7 supports diagnosis.
