Question 1 of 5
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?
Correct Answer: B
Rationale: The correct answer is B: Protamine sulfate. Protamine sulfate is the antidote for heparin overdose, as it works by binding to heparin to neutralize its anticoagulant effects. In this scenario, the client's symptoms of coughing up blood and blood in the stool indicate a potential heparin overdose, which can lead to excessive bleeding. Administering protamine sulfate will help reverse the effects of heparin and stop the bleeding.
Option A: Benztropine is an anticholinergic medication used to treat Parkinson's disease and extrapyramidal symptoms. It is not indicated for heparin overdose.
Option C: Vitamin K is the antidote for warfarin, a different type of anticoagulant. It is not effective for reversing the effects of heparin.
Option D: Digibind is the antidote for digoxin toxicity, not heparin overdose. It is not appropriate for this situation.
