Organophosphate
Poisoning (MCQ)
1- Complications of organophosphate poisoning are due to:
A- Accumulation of acetylcholine.
B- CNS depression.
C- Renal and hepatic failure due to formation of toxic metabolites.
معز.د
D- All of the above are expected complications.
شلفيط
2- The cholinergic toxidromes include the following, except:
A- Mydriasis.
B- Diaphoresis.
C- Bronchospasm.
D- Diarrhea.
3- Nicotinic effect is the most serious toxic effect in organophosphate
poisoning because:
A- This effect is not responsive to atropine sulphate injection.
B- It leads to a muscular weakness and respiratory failure.
C- It leads to severe hypertension and circulatory failure.
D- It leads to CNS depression and irreversible coma.
E- Both (A) & (B).
4- One of the following statements regarding organophosphates is not true:
A- They can be absorbed by any route.
B- They act by inhibiting acetylcholine.
C- They can cause chronic poisoning.
D- They induce pupillary constriction.
5- Why is it so important to give 2-PAM in the treatment of parathion:
A- Atropine sulphate is not enough for nicotinic effect.
B- To help free the complexes AchE.
C- To prevent more inhibition of AchE by binding with parathion.
D- All of the above.
6- What role does atropine sulphate play in the treatment of organophosphate
poisoning
A- It frees the complexes enzyme ACHE.
B- It antagonizes the Muscarinic and CNA effects.
C- It counteracts the rise of ACH leading to nicotinic effect.
D- All of the above.
