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.

Correct Answer is A
Explanation
Choice A rationale
Gemfibrozil is used to reduce elevated plasma triglycerides (VLDL) and increase HDL levels, which helps in managing hyperlipidemia.
Choice B rationale
This choice is incorrect as gemfibrozil does not reduce HDL but rather increases it while reducing plasma triglycerides (VLDL).
Choice C rationale
Gemfibrozil is not indicated for the treatment of hypertension; it is used for lipid disorders.
Choice D rationale
Gemfibrozil is not used for the treatment of deep vein thrombosis (DVT); it is specifically used to manage lipid levels.
Correct Answer is ["A","B","E"]
Explanation
Choice A rationale
Gemfibrozil is a fibrate that reduces triglycerides and increases HDL cholesterol, commonly used to treat hyperlipidemia.
Choice B rationale
Simvastatin is a statin that inhibits HMG-CoA reductase, reducing LDL cholesterol levels and is used in managing hyperlipidemia.
Choice C rationale
Enalapril is an ACE inhibitor used to manage hypertension and heart failure, not typically used for hyperlipidemia.
Choice D rationale
Warfarin is an anticoagulant used to prevent blood clots and is not used for treating hyperlipidemia.
Choice E rationale
Fenofibrate is another fibrate like gemfibrozil, used to reduce triglycerides and increase HDL cholesterol, making it an anti-lipemic medication.
