Which drug is the antidote for organophosphate (insecticide) poisoning, used to reverse muscarinic effects?
सही उत्तर: क) Atropine
Atropine blocks muscarinic receptors and reduces secretions and bradycardia caused by excess acetylcholine. Pralidoxime is added to reactivate cholinesterase; neostigmine would worsen toxicity.

A client on digoxin reports nausea and seeing yellow-green halos around lights. What should the nurse suspect?

Gastrointestinal upset and visual changes such as yellow-green halos are classic signs of digoxin toxicity. The nurse should hold the dose and check a serum digoxin level.

-
Which electrolyte imbalance increases the risk of digoxin toxicity?
सही उत्तर: ग) Hypokalemia
Low potassium increases digoxin binding to the Na+/K+-ATPase pump, enhancing toxicity. This is why potassium is monitored in clients on digoxin with loop diuretics.

-
Which drug is used to treat severe digoxin toxicity with life-threatening dysrhythmias?
सही उत्तर: ख) Digoxin immune fab (DigiFab)
Digoxin immune fab binds free digoxin and removes it from its site of action. Calcium is avoided in digoxin toxicity because it may worsen dysrhythmias.

Which antidote is used for iron poisoning?
सही उत्तर: क) Deferoxamine
Deferoxamine chelates free iron, which is excreted in urine (often giving it a reddish 'vin rosé' colour). Dimercaprol is used for arsenic, mercury and lead.

-
Which agent is used to reverse the anticoagulant effect of warfarin?
सही उत्तर: घ) Vitamin K (phytonadione)
Vitamin K allows the liver to synthesise clotting factors II, VII, IX and X that warfarin inhibits. Protamine reverses heparin, not warfarin.

-
Which drug is the specific antagonist for benzodiazepine overdose?
सही उत्तर: ग) Flumazenil
Flumazenil competitively blocks the benzodiazepine binding site on the GABA-A receptor. It can precipitate seizures in long-term benzodiazepine users, so it is used cautiously.

-
Which drug reverses respiratory depression caused by opioid overdose?
सही उत्तर: ख) Naloxone
Naloxone is a competitive opioid receptor antagonist. Flumazenil reverses benzodiazepines, not opioids.
