Which of the following is administered to increase the number of circulating red blood cells?

Oprelvekin (Neumega)

Epoetin alfa (Procrit)

Clopidogrel (Plavix)

Filgrastim (Neupogen)

Answer and Explanation

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.

Correct Answer is C

Explanation

A. Ferrous sulfate: This is an iron supplement and wouldn't be used to reverse warfarin's anticoagulant effect.

B. Prednisone: This is a steroid medication used for various inflammatory conditions and wouldn't be used to address excessive blood thinning.

C. Vitamin K: Vitamin K is the antidote for warfarin poisoning or excessive anticoagulation. By providing vitamin K, the body can resume producing clotting factors, counteracting warfarin's effect.

D. Heparin: This is another blood thinner medication. While it can be used in specific situations, it wouldn't be the first choice to reverse warfarin's effect because it adds another layer of anticoagulation, which could be risky.

A. "Drink a glass of water after each dose of your new drug." B. "Avoid taking other medications that can cause bleeding, such as NSAIDS like ibuprofen." C. "Follow up with the prescribed laboratory testing needed to monitor your clotting values." D. "Eat foods high in Vitamin K and calcium to help prevent clotting." E. "Continue to take your newly prescribed medications until your prescriber tells you not to do so." F. “Report any unexpected bleeding to your primary health provider."

Correct Answer is {"A":{"answers":"B"},"B":{"answers":"A"},"C":{"answers":"B"},"D":{"answers":"B"},"E":{"answers":"A"},"F":{"answers":"A"}}

Explanation

Essential

1. "Avoid taking other medications that can cause bleeding, such as NSAIDs like ibuprofen." Both aspirin and clopidogrel increase the risk of bleeding. NSAIDs like ibuprofen can further increase this risk, so it is crucial to avoid them unless advised otherwise by a healthcare provider.

2. "Continue to take your newly prescribed medications until your prescriber tells you not to do so." Discontinuing aspirin and clopidogrel without medical advice can increase the risk of stent thrombosis and other complications. It is essential to follow the prescribed regimen strictly.

3. “Report any unexpected bleeding to your primary health provider." Monitoring for signs of bleeding (such as bruising, blood in the stool or urine, or unusual bleeding) is important due to the increased bleeding risk associated with these medications. Prompt reporting can help manage and mitigate serious complications.

Unrelated

1. "Drink a glass of water after each dose of your new drug." While staying hydrated is generally good advice, it is not specifically relevant to the efficacy or safety of aspirin and clopidogrel.

2. "Follow up with the prescribed laboratory testing needed to monitor your clotting values." Routine clotting tests (such as INR, PT, or aPTT) are not typically required for monitoring the effects of aspirin and clopidogrel, as these medications do not usually require lab monitoring like warfarin does.

3. "Eat foods high in Vitamin K and calcium to help prevent clotting." This advice is unrelated because Vitamin K can counteract the effects of anticoagulants like warfarin but does not affect the action of antiplatelet drugs like aspirin and clopidogrel. Calcium intake is also unrelated to the management of these medications.
