. A patient is seen in the clinic with severe anemia. His religious beliefs prohibit the administration of blood products. His physician prescribes epoetin alfa (Epogen, Procrit) therapy. What other agent will the physician likely prescribe? 1\. myeloablative therapy 2\. a nonsteroidal anti-inflammatory drug 3\. an antimetabolite 4\. ferrous sulfate (Feosol, Feratab)

Short Answer

Expert verified
The physician will likely prescribe ferrous sulfate.

Step by step solution

01

Identify the Medical Condition

The patient is diagnosed with severe anemia, which indicates a deficiency in the number or quality of red blood cells, or the amount of hemoglobin they contain.
02

Review Epoetin Alfa Purpose

Epoetin alfa (Epogen, Procrit) is a medication that stimulates the production of red blood cells and is commonly used to treat anemia, especially in patients who cannot receive blood transfusions.
03

Determine Supporting Treatment

In addition to stimulating red blood cell production, the body needs the necessary building blocks to make new red blood cells. Therefore, the physician would likely prescribe a treatment that provides these essentials.
04

Evaluate Medication Options

Myeloablative therapy isn't used here as it destroys bone marrow rather than supporting red blood cell production. Nonsteroidal anti-inflammatory drugs don't help with anemia directly, nor do antimetabolites. Ferrous sulfate, however, is an oral iron supplement, which can increase the iron available for new hemoglobin production.
05

Select the Supporting Agent

Given that iron is crucial for hemoglobin production and epoetin alfa boosts red blood cell production, the physician will likely prescribe ferrous sulfate alongside epoetin alfa.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Epoetin Alfa
Epoetin Alfa is a remarkable therapeutic agent used primarily for individuals suffering from anemia, particularly when blood transfusions are not an option. It functions by imitating a natural hormone in the body, erythropoietin, which is essential for promoting the production of red blood cells in the bone marrow.
Epoetin Alfa comes to the rescue when red blood cell counts are critically low, as seen in severe cases of anemia. This condition can occur due to various reasons, including chronic kidney disease, chemotherapy, or certain chronic illnesses that affect blood production.
  • It helps alleviate symptoms of anemia such as fatigue and weakness by ensuring that more oxygen-carrying red blood cells circulate in the body.
  • Patients who avoid blood transfusions for religious beliefs find Epoetin Alfa particularly useful as it allows the body's natural mechanisms to enhance blood production without external blood products.
Overall, Epoetin Alfa plays a vital role in managing anemia by boosting the body's natural ability to produce red blood cells, hence helping in effectively addressing the condition.
Iron Supplementation
Iron supplementation is a critical adjunct therapy for those receiving Epoetin Alfa to treat anemia. Iron is a fundamental component needed for the synthesis of hemoglobin, the protein in red blood cells responsible for oxygen transport throughout the body.
When red blood cell production is stimulated, as with Epoetin Alfa, the demand for iron increases dramatically to make new hemoglobin—the key ingredient of red blood cells. Thus, adding iron supplements such as ferrous sulfate ensures there is enough iron available to meet this increased demand.
  • Iron supplements come in different forms, with ferrous sulfate being among the most common and effective for boosting iron levels in the body.
  • Regular iron intake is crucial to support the efficacy of treatments like Epoetin Alfa, assisting in both red blood cell production and maintenance of adequate hemoglobin levels.
Lasting results in treating anemia depend on balancing iron availability with stimulated red blood cell production, making supplementation a pivotal part of the treatment plan.
Red Blood Cell Production
Red blood cell production, also known as erythropoiesis, is a critical process in the human body that ensures all tissues receive an ample supply of oxygen.
This process predominantly occurs in the bone marrow, where stem cells develop into mature red blood cells equipped with hemoglobin. Hemoglobin is the protein that binds oxygen in the lungs and releases it in tissues, playing a central role in maintaining cellular function across the entire body.
  • Erythropoiesis is heavily influenced by various factors, including availability of nutrients like iron and the presence of erythropoietin—a hormone synthesized primarily by the kidneys.
  • In cases where anemia is present, promoting red blood cell production becomes crucial, and therapies like Epoetin Alfa are specifically designed to accelerate this process.
The successful treatment of anemia hinges on effectively increasing red blood cell production, making it an integral focus in medical management strategies to restore and maintain optimal health.

. The physician orders 1000 milliliters of D5NS for a patient. The nurse will hang: 1\. 5 percent dextrose in 0.9 percent sodium chloride. 2\. isotonic sodium chloride with 5 grams of dextrose added to the liter bag by the pharmacy. 3\. normal saline after she has added 5 grams of dextrose to a liter bag. 4\. 5 percent dextrose in any saline solution concentration.

One drug can alter the absorption of another drug. One drug increases intestinal motility. What effect will this have on the second drug? 1\. None; absorption of the second drug is not affected. 2\. The increased gut motility increases the absorption of the second drug. 3\. The absorption of the second drug cannot be predicted. 4\. Less of the second drug will be absorbed.

A patient is admitted with a deep vein thrombosis (DVT) in his leg. The physician will order an intravenous infusion of: 1\. morphine. 2\. a sedative. 3\. heparin sodium. 4\. a vasodilator

In hanging a parenteral IV fluid that is to be infused by gravity, rather than with an infusion pump, the nurse notes that the IV tubing is available in different drop factors. Which tubing is a microdrop set? 1\. 15 drops per milliliter 2\. 60 drops per milliliter 3\. 20 drops per milliliter 4\. 10 drops per milliliter

Your patient takes levothyroxine (Synthroid) for hypothyroidism and warfarin (Coumadin) for deep vein thrombosis prophylaxis. What is the possible interaction between these drugs? 1\. There is no interaction. 2\. There is an increased risk for bleeding. 3\. There is an increased risk for cardiovascular effects from levothyroxine. 4\. The warfarin dose may need to be increased to anticoagulate the blood.
