1: What is the purpose of differential diagnoses?
Correct Answer: To identify and rule out multiple potential conditions to reach the correct diagnosis
1. Differential diagnosis is a systematic method of generating a list of possible conditions based
on history and physical exam.
2. Each potential diagnosis is tested against clinical findings to rule in or rule out.
3. Prioritizes life-threatening and common conditions first.
2: Where in the SOAP note is the diagnosis documented?
Correct Answer: In the Assessment section
1. SOAP = Subjective, Objective, Assessment, Plan.
2. Assessment includes differential diagnoses, primary diagnosis, and reasoning.
3. Plan includes diagnostic tests, medications, referrals, patient education.
3: Define specificity and sensitivity in disease diagnosis.
Correct Answer: Specificity measures true negatives; sensitivity measures true positives
1. Sensitivity = ability to correctly identify those WITH the disease (true positive rate). “SNOUT”
– Sensitive test, Negative result rules OUT disease.
2. Specificity = ability to correctly identify those WITHOUT the disease (true negative rate).
“SPIN” – Specific test, Positive result rules IN disease.
3. Both are measures of test accuracy.
4: What are sources for clinical decision-making?
Correct Answer: Evidence-based research, clinical practice guidelines
1. Evidence-based practice integrates best research evidence, clinical expertise, and patient
values.
2. Guidelines from professional organizations (CDC, USPSTF, AAFP) provide recommendations.
3. Clinical decision support tools also aid decision-making.
, 5: Define evidence-based practice.
Correct Answer: The integration of best research evidence with clinical expertise and patient values
1. EBP is the gold standard for clinical decision-making.
2. Requires systematic review of literature and critical appraisal.
3. Incorporates patient preferences and clinical context.
6: What is a systematic literature review?
Correct Answer: A summary of all relevant studies on a specific clinical question using systematic
methods
1. Systematic reviews use explicit, reproducible methods to identify, select, and appraise studies.
2. Meta-analysis may combine results statistically.
3. Provides high-quality evidence for clinical guidelines.
7: Rubella is also known as?
Correct Answer: German measles
1. Rubella is a viral exanthem (3-day measles) with mild prodrome, post-auricular/occipital
lymphadenopathy.
2. Rash: pink macules/papules starting on face, spreading to trunk.
3. Teratogenic if contracted in pregnancy (congenital rubella syndrome).
8: What is telogen effluvium?
Correct Answer: A temporary hair loss condition caused by stress or trauma
1. Telogen effluvium occurs 2-3 months after a physiologic stressor (illness, surgery, childbirth,
weight loss, medication).
2. Diffuse hair shedding; self-limited, resolves in 6 months.
3. Reassure patient; no treatment needed unless persistent.
9: How is intensely dry skin managed?
Correct Answer: With emollients, moisturizers, and avoiding irritants
1. Thick emollients (petrolatum, ceramides) repair skin barrier.
2. Apply immediately after bathing; use lukewarm water, mild cleansers.
3. Avoid long hot showers, harsh soaps, fragrances.
10: How is urticaria managed?
Correct Answer: With antihistamines and identifying/removing triggers
1. Urticaria (hives): raised, pruritic wheals.
2. First-line: non-sedating antihistamines (loratadine, cetirizine, fexofenadine).
3. Identify triggers: medications, foods, infections, stress, physical stimuli.
