Q- Which of the following drugs is used after chemotherapy to increase the leukocyte count if it drops?
A- Dexamethasone
B- Filgrastim
C- Interleukin-2
D- Prednisone
B- Filgrastim- Filgrastim (G-CSF) stimulates the bone marrow to increase neutrophil production and is commonly used after chemotherapy to treat or prevent neutropenia. Dexamethasone and prednisone are corticosteroids, and IL-2 is used to stimulate T-cell proliferation, not leukocyte recovery after chemotherapy.
Q- Which of the following drugs has the shortest half-life and is used in acute anxiety?
A- Alprazolam
B- Chlordiazepoxide
C- Clonazepam
D- Flurazepam
A- Alprazolam- Alprazolam has a short half-life and rapid onset of action, making it suitable for acute anxiety episodes. Chlordiazepoxide, clonazepam, and flurazepam all have longer half-lives and are not ideal for quick, short-term relief.
Q- Which one of these drugs reverses both muscarinic and nicotinic effects of organophosphorus compounds by restoring cholinesterase?
A- Atracurium
B- Atropine
C- Physostigmine
D- Pralidoxime
D- Pralidoxime- Pralidoxime reactivates acetylcholinesterase, reversing both muscarinic and nicotinic effects of organophosphate poisoning. Atropine blocks muscarinic symptoms only, and physostigmine actually increases acetylcholine. Atracurium is a neuromuscular blocker and has no role here.
