A nurse is caring for a client who is prescribed heparin via intravenous (IV). 40 minutes after the administration of heparin, the client reports "coughing up blood" and notes there is blood in his stool.
Based on the client's presenting symptoms, which of the following options is an antidote for this client?
Benztropine.
Protamine sulfate.
Vitamin K.
Digibind.
The Correct Answer is B
Choice A rationale
Benztropine is an anticholinergic agent used to treat Parkinsonism and extrapyramidal symptoms, not suitable for reversing heparin effects.
Choice B rationale
Protamine sulfate is the specific antidote for heparin overdose. It works by neutralizing the anticoagulant effects of heparin.
Choice C rationale
Vitamin K is an antidote for warfarin overdose, promoting the synthesis of clotting factors, but ineffective against heparin.
Choice D rationale
Digibind is an antidote for digoxin toxicity, not appropriate for counteracting heparin.
