A client taking warfarin (Coumadin) should be instructed to avoid herbal supplements such as green tea, ginkgo, feverfew, garlic, and ginger because these could:

Increase the risk for bleeding

Cause severe headache

Decrease the effects of the warfarin (Coumadin)

Cause severe hypotension

Answer and Explanation

The Correct Answer is A

A. Increase the risk for bleeding: Herbal supplements like green tea, ginkgo, feverfew, garlic, and ginger can potentiate the effects of warfarin by enhancing its anticoagulant properties. This increases the risk of bleeding, as warfarin itself is a blood thinner designed to prevent clot formation. These herbs can further inhibit platelet aggregation or enhance anticoagulation, leading to a higher risk of bleeding complications.

B. Cause severe headache: While some herbal supplements can cause headaches as a side effect, this is not the primary concern when combined with warfarin. The interaction between these herbs and warfarin does not commonly result in severe headaches. The primary issue is the increased risk of bleeding.

C. Decrease the effects of the warfarin (Coumadin): These particular herbal supplements do not generally decrease the effects of warfarin. In fact, they are more likely to increase its anticoagulant effects. Some other substances might interfere with warfarin's efficacy, but the herbs listed are known to enhance its bleeding risk.

D. Cause severe hypotension: Severe hypotension is not a common result of combining these herbal supplements with warfarin. The primary interaction is related to the blood-thinning effects, not to blood pressure regulation. Herbal supplements that might affect blood pressure are not typically those that interact significantly with warfarin in this manner.

Correct Answer is B

Explanation

A. Oprelvekin (Neumega): Oprelvekin is a recombinant human interleukin-11 (IL-11) used to stimulate the production of platelets, not red blood cells. It is primarily indicated for patients with thrombocytopenia (low platelet count) due to chemotherapy.

B. Epoetin alfa (Procrit): Epoetin alfa is a synthetic form of erythropoietin, a hormone produced by the kidneys that stimulates the production of red blood cells in the bone marrow. It is commonly used to treat anemia associated with chronic kidney disease, chemotherapy, or HIV therapy. Therefore, it is administered to increase the number of circulating red blood cells.

C. Clopidogrel (Plavix): Clopidogrel is an antiplatelet medication that inhibits platelet aggregation, thereby reducing the risk of blood clots. It does not directly stimulate the production of red blood cells.

D. Filgrastim (Neupogen): Filgrastim is a recombinant human granulocyte colony-stimulating factor (G-CSF) that stimulates the production of white blood cells, particularly neutrophils, in the bone marrow. It is used to treat neutropenia (low white blood cell count) caused by chemotherapy, bone marrow transplantation, or certain diseases. It does not directly stimulate the production of red blood cells.

A. Most CAM therapies are totally ineffective B. Additional treatment may not be needed C. Patients must be warned that most CAM therapies are dangerous D. CAM therapies could interact with prescription and OTC medications

Correct Answer is D

Explanation

A. Most CAM therapies are totally ineffective: Incorrect. Dismissing all CAM therapies as ineffective without considering individual cases could lead to overlooking potentially helpful treatments for patients.

B. Additional treatment may not be needed: Incorrect. Collecting information about CAM use allows healthcare providers to assess the overall treatment regimen comprehensively.

C. Patients must be warned that most CAM therapies are dangerous: Incorrect. While some CAM therapies may carry risks, it's not accurate to generalize that most CAM therapies are dangerous.

D. CAM therapies could interact with prescription and OTC medications: Correct. Understanding potential interactions between CAM therapies and conventional medications is essential for patient safety and optimal treatment outcomes.
