Which of the following is administered to increase the number of circulating red blood cells?
Oprelvekin (Neumega)
Epoetin alfa (Procrit)
Clopidogrel (Plavix)
Filgrastim (Neupogen)
The Correct Answer is B
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.

Explanation
A. Echinacea: Potential anticoagulant effects may increase the risk of bleeding when combined with warfarin.
B. Garlic: Garlic supplements have anticoagulant properties, which can increase the risk of bleeding when combined with warfarin.
C. Ginseng: Ginseng has antiplatelet effects, increasing the risk of bleeding when combined with warfarin.
D. Valerian: Valerian may interact with warfarin, potentially increasing the risk of bleeding.
E. Ginger: Ginger has antiplatelet effects, which can increase the risk of bleeding when combined with warfarin.
Correct Answer is D
Explanation
A. Easy bruising indicates the medication is effective: While some bruising is possible, excessive bruising doesn't necessarily mean the medication is working effectively. It could indicate excessive anticoagulation, requiring dose adjustments.
B. Inject the medication deep into the thigh muscle: Heparin is injected subcutaneously, targeting the fatty tissue layer just beneath the skin. Injecting into the muscle can be painful and decrease absorption.
C. Expect stools to become black and tarry: Black stools can be a sign of upper gastrointestinal bleeding, a potential but uncommon side effect. The nurse should instruct the client to report any black stools but not expect them as a normal occurrence.
D. Use a soft bristle toothbrush: This is important because heparin increases bleeding risk, and a soft-bristled toothbrush minimizes gum irritation and potential bleeding.
