Instructions: Each question includes the verified correct answer and a detailed clinical pharmacology
rationale.
1: What is the appropriate treatment for fungal otitis externa?
Correct Answer: Treatment involves cleaning and 2% acetic acid solution application.
1. Acetic acid creates acidic environment inhibiting fungal growth (Aspergillus, Candida).
2. Topical antifungal drops (clotrimazole) if acetic acid fails.
3. Avoid antibiotics which worsen fungal infection.
2: What is the appropriate treatment for bacterial otitis externa?
Correct Answer: Involves cleaning and topical antimicrobials.
1. Topical fluoroquinolone drops (ciprofloxacin, ofloxacin) penetrate ear canal.
2. Avoid systemic antibiotics unless severe or spreading infection.
3. Keep ear dry during treatment; wick placement for edema.
3: What is the appropriate treatment for mild acne?
Correct Answer: Involves topical antibiotics and retinoids.
1. Topical retinoids (tretinoin, adapalene) normalize follicular keratinization.
2. Topical antibiotics (clindamycin, erythromycin) reduce Cutibacterium acnes.
3. Benzoyl peroxide provides antibacterial effect without resistance.
4: What is the appropriate treatment for moderate acne?
Correct Answer: Involves oral antibiotics like doxycycline and comedolytics.
1. Oral tetracyclines (doxycycline, minocycline) for inflammatory acne.
2. Combined with topical retinoid and benzoyl peroxide for synergy.
3. Limit oral antibiotics to 3-4 months to reduce resistance.
5: What is the appropriate treatment for severe acne?
Correct Answer: Includes isotretinoin for effective treatment.
1. Isotretinoin reduces sebum production, normalizes keratinization, decreases C. acnes.
2. Teratogenic: requires iPledge program monitoring and two negative pregnancy tests.
3. Monitor triglycerides, LFTs, mood changes (depression risk).
, 6: What complication is associated with eczema treatment using Tacrolimus?
Correct Answer: Risk of cancer with Tacrolimus use.
1. Topical calcineurin inhibitors (TCI) carry FDA boxed warning for lymphoma/skin cancer.
2. Risk based on animal studies; clinical significance in humans controversial.
3. Reserve for second-line, short-term use in patients >2 years.
7: What is the treatment for eczema?
Correct Answer: Involves Tacrolimus and Pimecrolimus.
1. Topical calcineurin inhibitors for moderate-severe atopic dermatitis.
2. Useful for steroid-induced atrophy, face, neck, intertriginous areas.
3. Apply twice daily; burning sensation common first few days.
8: What are examples of penicillin antibiotics?
Correct Answer: Include any 'cillin' antibiotics.
1. Amoxicillin, ampicillin, penicillin VK, piperacillin, nafcillin, oxacillin.
2. Mechanism: inhibit cell wall synthesis (beta-lactam binding to PBPs).
3. Cross-allergy with cephalosporins ~1-2% for severe reactions.
9: What are examples of cephalosporin antibiotics?
Correct Answer: Include Cephalexin, cefoxitin, cefotaxime, and more.
1. Generations: 1st (cephalexin), 2nd (cefoxitin), 3rd (ceftriaxone), 4th (cefepime), 5th (ceftaroline).
2. Broader gram-negative coverage with higher generations.
3. Ceftriaxone contraindicated in neonates with hyperbilirubinemia (displaces bilirubin).
10: What are examples of carbapenem antibiotics?
Correct Answer: Include antibiotics like imipenem.
1. Imipenem/cilastatin, meropenem, ertapenem, doripenem.
2. Broadest spectrum beta-lactams; reserve for multidrug-resistant organisms.
3. Imipenem lowers seizure threshold (caution with CNS lesions).
11: What monitoring is needed for penicillin antibiotics?
Correct Answer: Include renal impairment and drug level monitoring.
1. Penicillins excreted renally; dose adjustment for CrCl <30 mL/min.
2. High doses may cause neurotoxicity (seizures) in renal failure.
3. Monitor for hypersensitivity, C. diff, electrolyte disturbances (Na+ content).
12: What monitoring is needed for cephalosporin antibiotics?
Correct Answer: Monitoring includes renal impairment and drug levels.
1. Renal dose adjustment for most cephalosporins (except ceftriaxone hepatically excreted).
2. Monitor for C. diff, bleeding (moxalactam, cefoperazone - vitamin K deficiency).
3. Ceftriaxone biliary sludging in neonates (avoid with calcium).
