Format: Q&A Guide with Clinical Rationale
1: The most common cause of syncope is...
Correct Answer: Vasovagal syncope (neurally mediated).
1. Vasovagal syncope is triggered by emotional stress, pain, prolonged standing.
2. Results from inappropriate reflex response causing bradycardia and vasodilation.
3. Typically preceded by prodromal symptoms (nausea, sweating, lightheadedness).
2: What is angioedema?
Correct Answer: Localized areas of painless swelling beneath the skin, often around the eyes and lips,
but it can also involve other body areas as well. Often triggered by an allergic reaction.
1. Can involve airway (laryngeal edema) requiring emergency management.
2. Distinguish from urticaria: swelling is deeper, not pruritic.
3. Causes: ACE inhibitors, allergies, hereditary angioedema.
3: Treatment for EBV
Correct Answer: Rest and symptomatic therapy. OTC medications for pain/fever, increase fluid intake.
1. No antiviral indicated for uncomplicated infectious mononucleosis.
2. Avoid contact sports for 4-6 weeks due to splenomegaly risk.
3. Corticosteroids for impending airway obstruction or severe complications.
4: This immunoglobin is responsible for allergen development
Correct Answer: IgE (Immunoglobulin E).
1. IgE binds to mast cells and basophils, triggering histamine release.
2. Elevated in atopic conditions (asthma, allergic rhinitis, eczema).
3. Involved in Type I hypersensitivity reactions.
5: Signs and Symptoms of acute bronchospasm
Correct Answer: Spasmodic cough, wheezing, shortness of breath (SOB).
1. Expiratory wheezing is characteristic of bronchospasm.
2. May progress to use of accessory muscles, tachypnea, hypoxia.
3. Silent chest is ominous sign of severe obstruction.
, 6: Three options for emergency contraception
Correct Answer: Plan B (levonorgestrel), Ulipristal acetate (Ella), IUD (copper or hormonal).
1. Levonorgestrel effective up to 72 hours post-intercourse.
2. Ulipristal acetate effective up to 120 hours; requires prescription.
3. Copper IUD most effective (99%) up to 5 days post-intercourse.
7: What diabetic meds increase weight gain?
Correct Answer: Insulin, Thiazolidinediones (Rosiglitazone & Pioglitazone).
1. Insulin promotes adipogenesis and weight gain.
2. Thiazolidinediones cause fluid retention and increased adiposity.
3. Metformin, SGLT2 inhibitors, GLP-1 agonists promote weight loss or neutral.
8: Causes of syncope
Correct Answer: Neurally mediated (most common), orthostatic hypotension, cardiac (most severe).
1. Neurally mediated: vasovagal, situational, carotid sinus hypersensitivity.
2. Orthostatic: volume depletion, autonomic dysfunction, medications.
3. Cardiac: arrhythmias, structural heart disease (most lethal if missed).
9: This scale is used to measure severity of damage from head trauma and scores these three
categories
Correct Answer: Glasgow Coma Scale (highest score is 15). Categories: Eye Opening, Best Motor
Response, Best Verbal Response.
1. GCS 13-15 mild, 9-12 moderate, 3-8 severe TBI.
2. Motor response most predictive of outcome.
3. Intubation indicated for GCS ≤8.
10: What med classes are associated with weight gain?
Correct Answer: Diabetic meds, antidepressants, neuroleptics, seizure meds, antihistamines, hormonal
preparations, and cardiac meds (beta-blockers & antiarrhythmics).
1. Antidepressants: SSRIs, TCAs, MAOIs cause weight gain (especially paroxetine).
2. Neuroleptics: clozapine, olanzapine cause most significant weight gain.
3. Beta-blockers: older agents (propranolol) cause more weight gain than cardioselective.
11: Tests to order for cases of presyncope/syncope episodes
Correct Answer: CT Scan/MRI, EKG, Labs: CBC, Lytes, glucose, Mg, BUN/Cr, UA, ABGs, Coag
Panel, Drug screen.
1. EKG to rule out arrhythmias (prolonged QT, heart block).
2. Cardiac monitoring if suspected arrhythmia.
3. Orthostatic vital signs to assess for postural hypotension.
