therapy for hypothyroidism.
8. Long-term use of which drug class can lead to osteoporosis and adrenal suppression?
A. NSAIDs
B. Corticosteroids
C. Opioids
D. Antibiotics
Answer: B. Corticosteroids

C. Liver function tests
D. Urinalysis
Answer: B. Serum lithium levels
Rationale: Lithium has a narrow therapeutic index and requires regular serum level
monitoring.
12. Which drug is a selective serotonin reuptake inhibitor (SSRI)?
A. Amitriptyline
B. Fluoxetine
C. Phenelzine
D. Bupropion
Answer: B. Fluoxetine
Rationale: Fluoxetine is an SSRI that inhibits serotonin reuptake.
13. A patient taking an MAO inhibitor should avoid which of the following?
A. Tyramine-rich foods
B. Dairy products
C. Green leafy vegetables
D. Whole grains
Answer: A. Tyramine-rich foods
Rationale: Tyramine can precipitate a hypertensive crisis in patients on MAO inhibitors.
14. Which antipsychotic is most associated with extrapyramidal symptoms?
A. Clozapine
B. Olanzapine
C. Haloperidol
D. Quetiapine
Answer: C. Haloperidol
Rationale: Haloperidol is a typical antipsychotic with a high risk of extrapyramidal symptoms.
15. Which drug is used to reverse heparin anticoagulation?
A. Vitamin K
B. Protamine sulfate
C. Naloxone
D. Flumazenil
Answer: B. Protamine sulfate
Rationale: Protamine sulfate binds to heparin and neutralizes its anticoagulant effect.
16. Which medication is a direct oral anticoagulant (DOAC)?
A. Warfarin
B. Heparin
C. Rivaroxaban
D. Aspirin
Answer: C. Rivaroxaban
Rationale: Rivaroxaban is a direct factor Xa inhibitor, a type of DOAC.
, 17. Which drug is a loop diuretic?
A. Hydrochlorothiazide
B. Furosemide
C. Spironolactone
