During a follow-up visit with a patient recently started on Coumadin, the home health nurse is concerned after seeing an herbal remedy that enhances the effect of anticoagulants by the patient's bedside.
What is this herbal remedy?
Asian ginseng.
Cayenne.
Aloe vera.
Kava.
The Correct Answer is A
The correct answer is choice a. Asian ginseng.
Choice A rationale:
Asian ginseng is known to enhance the effect of anticoagulants like Coumadin (warfarin). It can increase the risk of bleeding by potentiating the anticoagulant effect.
Choice B rationale:
Cayenne contains salicylates, which have blood-thinning properties, but it is not as well-documented for enhancing the effect of anticoagulants as Asian ginseng.
Choice C rationale:
Aloe vera is not known to significantly affect anticoagulant medications. It is primarily used for its soothing and healing properties on the skin.
Choice D rationale:
Kava is primarily used for its sedative and anxiolytic effects. It does not have a significant impact on anticoagulant medications.

Correct Answer is D
Explanation
Choice A rationale:
Chambers refer to the four compartments of the heart, not a layer of the heart.
Choice B rationale:
Pericardium is the sac that surrounds the heart, not a layer of the heart itself.
Choice C rationale:
Epicardium is the outermost layer of the heart, not the innermost.
Choice D rationale:
Endocardium is indeed the innermost layer of the heart, lining the inner surfaces of the heart chambers and valves.
Correct Answer is A
Explanation
Choice A rationale:
The right ventricle pumps deoxygenated blood to the lungs via the pulmonary artery. This is the only artery in the body that carries deoxygenated blood.
Choice B rationale:
The left atrium receives oxygenated blood from the lungs via the pulmonary veins, not the right ventricle.
Choice C rationale:
Pulmonary veins carry oxygenated blood from the lungs to the left atrium, not from the right ventricle to the lungs.
Choice D rationale:
The left ventricle pumps oxygenated blood to the rest of the body through the aorta, not to the lungs.
