1. A patient with epilepsy becomes pregnant. Which antiepileptic drug is most teratogenic and should be avoided? → Valproate (valproic acid) — highest risk of neural tube defects and cognitive impairment
2. Which receptor type mediates the therapeutic bronchodilation effect of salbutamol (albuterol)? → Beta-2 adrenergic receptor in bronchial smooth muscle
3. The SFDA requires that pharmaceutical manufacturers comply with which international standard for manufacturing quality? → Good Manufacturing Practice (GMP) — ICH Q10 and national GMP guidelines
4. A pharmacist reviews a patient's medication for potential QT prolongation risk. Which combination creates the highest risk for torsades de pointes? → Amiodarone + azithromycin + hypokalemia
5. A patient with peptic ulcer disease positive for H. pylori is prescribed triple therapy. Which regimen is standard first-line? → PPI + clarithromycin + amoxicillin for 14 days
6. A patient with COPD is on a long-acting beta-2 agonist (LABA). Which combination is recommended to further reduce exacerbations in severe COPD? → LABA + long-acting muscarinic antagonist (LAMA) combination inhaler
7. Which adverse effect requires immediate discontinuation of clozapine? → Absolute neutrophil count (ANC) below 500/mm3 — agranulocytosis
8. Which antihypertensive class is contraindicated in pregnancy? → ACE inhibitors and ARBs
9. A pharmacist is reviewing the structure-activity relationships (SAR) of opioids. Which structural feature is essential for opioid receptor binding? → A phenolic hydroxyl group at position 3 and a tertiary nitrogen
10. A pharmacist identifies that a patient is prescribed both fluoxetine (SSRI) and tramadol. What is the clinical concern? → Serotonin syndrome and reduced tramadol activation (fluoxetine inhibits CYP2D6)
11. A parenteral nutrition bag contains the following per day: dextrose 300 g, amino acids 70 g, lipids 50 g. What is the total caloric content? → 2,170 kcal
12. What is the primary purpose of environmental monitoring in a pharmacy cleanroom? → To verify ongoing microbiological quality of the compounding environment
13. What is the primary advantage of lyophilization (freeze-drying) for sterile pharmaceutical products? → It improves long-term stability of moisture-sensitive drugs by removing water under vacuum
14. What does the acronym HEPA stand for in cleanroom air filtration? → High-Efficiency Particulate Air
15. Which antifungal drug inhibits ergosterol synthesis by targeting lanosterol 14-alpha demethylase (CYP51)? → Fluconazole (azole class)
16. Which antiseptic agent is preferred for skin antisepsis before insertion of an intravenous catheter? → Chlorhexidine gluconate 2%
17. An IV infusion of 500 mg drug is administered over 2 hours. The drug has a clearance of 10 L/hr and a half-life of 6 hours. What is the Vd? → 86.6 L
18. A patient on warfarin starts taking fluconazole for a vaginal yeast infection. What is the expected pharmacokinetic interaction? → Fluconazole inhibits CYP2C9, increasing warfarin levels and INR — increased bleeding risk
19. A 70-year-old patient is on warfarin (INR 2.5) and develops a significant GI bleed. What is the most rapid reversal option? → 4-factor prothrombin complex concentrate (PCC) plus IV vitamin K
20. Which class of drugs can cause hyperkalemia when combined with ACE inhibitors or ARBs? → Potassium-sparing diuretics and aldosterone antagonists (spironolactone, eplerenone)
21. Which therapeutic approach is used for acetaminophen (paracetamol) overdose? → N-acetylcysteine (NAC) IV or oral — replenishes glutathione to detoxify NAPQI
22. Which antiviral mechanism does oseltamivir (Tamiflu) use to treat influenza? → Neuraminidase inhibitor — prevents viral release from host cells
23. The drug-receptor interaction for a full agonist is best described as: → High affinity and high intrinsic efficacy — binds receptor and produces maximum response
24. What is the antidote for benzodiazepine overdose? → Flumazenil
25. Which of the following actions constitutes a violation of aseptic technique? → Touching the needle shaft while preparing an injectable
26. A drug has linear pharmacokinetics. The steady-state concentration at 100 mg/day is 5 mg/L. What steady-state concentration is expected at 200 mg/day? → 10 mg/L — linear kinetics means proportional increases
27. A patient on spironolactone develops gynecomastia. The pharmacist recommends switching to which potassium-sparing agent to avoid this side effect? → Eplerenone — selective MRA without anti-androgenic effects causing gynecomastia
28. For a heat-stable ophthalmic solution, which sterilization method provides the highest sterility assurance level (SAL)? → Terminal sterilization by autoclaving
29. What is the mechanism by which metronidazole kills anaerobic bacteria? → Reduced to reactive nitro radical intermediates that damage DNA
30. A patient weighing 80 kg has a serum creatinine of 2.5 mg/dL (age 55, male). Using the Cockcroft-Gault equation, calculate the estimated creatinine clearance. → CrCl = [(140-55) × 80] / [72 × 2.5] = 37.8 mL/min
