EmpoweRN.com This is a video nursing exam or NCLEX style question going over the medication coumadin. I have placed this video in the format that helped me pass nursing school with honors and the NCLEX examination on the first attempt in 75 questions. I know it may seem unreasonably long… but it is not. Take your time, follow the instructions and read each word slowly. Lets get started ;) Question Number 1 of 4: Title: NCLEX Question: Bridging Coumadin until INR Therapeutic A client was admitted for the treatment of deep vein thrombosis. The attending physician ordered the following medication: Heparin 5,000 units S.Q. every 8 hours, Warfarin (Coumadin) 5 mg P.O, start today. The nurse’s best action would be: A. Administer neither the heparin nor coumadin B. Administer both heparin and coumadin C. Administer only prescribed coumadin D. Administer only prescribed heparin Correct Answer: B – It takes several days for the Coumadin to reach its maximum anticoagulant effect, and heparin and Coumadin therapy sometimes overlap. For more questions & for the main video visit here: http://wp.me/s4CVjD-coumadin Warfarin aka Coumadin is the most used oral anticoagulant in the world and has been used for more than 50 years for therapy in prevention of thrombus formation and subsequent thromboembolic events. Anticoagulants are blood thinners which prevent formation of blood clots as well as prevent existent blood clots from increasing in size. Blood clots can hinder blood circulation and lead to serious medical conditions, like stroke, heart attack and pulmonary embolism. Thus warfarin is helpful in treating and preventing vein and artery blockage, stroke and heart attack. Mechanism of Action Warfarin slows down the formation of blood clots within 24 hours, but the complete effect takes place between 72 to 96 hours after taking the medication. Blood clot formation is a complicated process which requires certain compounds known as coagulating factors to be present. These coagulating factors are produced by the liver. In the presence of sufficient vitamin K. Warfarin acts by inhibiting the presence of vitamin K and this inhibits the formation of coagulating factors. Substances that require vitamin K for their formation are: the anticoagulant proteins C and S and factors II, VII, IX, and X. Therefore, medications like warfarin block coagulating factors and disturb the process of clot formation. Thus slowing down blood clot formation. In the case of blood clots that are already formed, warfarin stops the clot from getting bigger. It also prevents breakage of the clot which can be otherwise dangerous if it travels in the bloodstream and blocks blood vessels. Warfarin cannot destroy or dissolve a blood clot that is already there. But the blood clot itself may slowly dissolve with time. Nor can Warfarin reverse ischemic tissue damage either, but, may help avoid secondary thromboembolic complications that can be dangerous and even fatal.

Heart & Stroke Clinical Update 2015 www.heartandstroke.ca/clinicalupdate Plenary 3c Top Developments in Anticoagulant - Oral Anticoagulation for AF-related Stroke Prevention Presented by: Andrew Ha, MD, FRCPC (see below) Hilton Toronto, December 2015 Learning Objectives 1. Review common stroke and bleeding assessment schema for patients with atrial fibrillation (AF). 2. Review randomozed controlled trials comparing the efficacy and safety of warfarin versus noval oral anticoagulants (NOAC). 3. Discussion of “real-world” observational studies on the use of warfarin and NOAC agents. 4. Review the safety and effectiveness of oral anticoagulation in high-risk patient subgroups (e.g. chronic kidney disease). 5. Reversal agents for NOACs Session Description Stroke prevention with oral anticoagulation (OAC) is one of the most important treatment goals in the management of patients with atrial fibrillation (AF). Traditionally, warfarin is the drug of choice for AF-related stroke prevention. Recently, the introduction of novel oral anticoagulant (NOAC) agents has revolutionized this field. As a consequence of the rapid uptake of NOAC agents in clinical practice, health practitioners now face many new questions when prescribing OAC for AF patients with elevated stroke risk. For instance, there is a pressing need to develop a greater understanding of the “real-world” effectiveness and safety between warfarin and NOAC agents. In addition, further delineation of the risks and benefits of warfarin vs. NOAC agents in high-risk AF patient subgroups (e.g. elderly, patients with kidney disease, patients treated with antiplatelet therapy) will be most welcomed. In this session, we will examine data from randomized clinical trials, “real-world” registries, and large-scale health administrative databases to address these keys questions on OAC use for AF-related stroke prevention.

2 MINUTE NCLEX TIPS - Understanding PT/INR Labs ------------------------------------------------------------------------------------------------------ 0:19 PT (Prothrombin Time) 1:04 How to Calculate the Therapeutic Range for PT 1:34 INR (International Normalized Ratio) ------------------------------------------------------------------------------------------------------ For patients on anti-coagulation therapy, such as Coumadin, lab results must be monitored closely and must always be assessed before administration of the medication. ------- 2 Tests Are Used: PT and INR ------- PT (prothrombin time) is an older test, but is still sometimes used. The disadvantage to this test is that it varies from lab to lab. It requires a simple calculation for patients who are on anti-coagulation therapy. The therapeutic range is always 1.5 to 2 times the range indicated on the lab report. INR (International Normalized Ratio) is the current standard lab test to evaluate anti-coagulation therapy. It uses a standardized testing reagent, so it does not vary from lab to lab. No calculation is required to interpret the results. Additional Information: In healthy people an INR of 1.1 or below is considered normal. An INR range of 2.0 to 3.0 is typically an effective therapeutic range for people on anti-coagulation therapy ------------------------------------------------------------------------------------------------------ Medical Psychology of Wisconsin, LLC www.medicalpsych-wi.com

*Subscribe for more great NCLEX videos: https://www.goo.gl/8mBXbY On our first look at anticoagulants part 1, we looked at coumadin, the most commonly used oral anticoagulant. Now we will look at heparin, a commonly used injectable anticoagulant. Heparin is a pharmaceutical preparation of the naturally occurring anticoagulant produced by white blood cells in various body tissues, obtained from pig intestines or the lungs of cattle. It is an injectable blood thinner used to treat & prevent the formation of clots and the extension of existing clots within the blood. It does not break down clots that have already formed, but it allows the body’s natural clot lysis mechanisms to work normally to break down clots that have formed.

EmpoweRN.com Hi Guys! I really hope this video helps you out a ton! This medication is one of the major ones you will see in adult Med Surg & Critical care. Although it saves lives, we have to be very careful when taking care of patients with clotting tendencies. Furthermore, we must also educate our patients about diet restrictions, safety precautions and the importance of their follow up appointments. I hope this video simplifies at least a little bit of it ;) Also, remember... you can access the audio of the video to download on your device, so that not matter where you are, you can always be learning. If you prefer to watch the video without any music, you can go to my website... you will also find the audio there: http://wp.me/s4CVjD-coumadin I hope this & all of the videos help you tremendously. Much love, - Caroline Warfarin aka Coumadin is the most used oral anticoagulant in the world and has been used for more than 50 years for therapy in prevention of thrombus formation and subsequent thromboembolic events. Anticoagulants are blood thinners which prevent formation of blood clots as well as prevent existent blood clots from increasing in size. Blood clots can hinder blood circulation and lead to serious medical conditions, like stroke, heart attack and pulmonary embolism. Thus warfarin is helpful in treating and preventing vein and artery blockage, stroke and heart attack. Mechanism of Action Warfarin slows down the formation of blood clots within 24 hours, but the complete effect takes place between 72 to 96 hours after taking the medication. Blood clot formation is a complicated process which requires certain compounds known as coagulating factors to be present. These coagulating factors are produced by the liver. In the presence of sufficient vitamin K. Warfarin acts by inhibiting the presence of vitamin K and this inhibits the formation of coagulating factors. Substances that require vitamin K for their formation are: the anticoagulant proteins C and S and factors II, VII, IX, and X. Therefore, medications like warfarin block coagulating factors and disturb the process of clot formation. Thus slowing down blood clot formation. In the case of blood clots that are already formed, warfarin stops the clot from getting bigger. It also prevents breakage of the clot which can be otherwise dangerous if it travels in the bloodstream and blocks blood vessels. Warfarin cannot destroy or dissolve a blood clot that is already there. But the blood clot itself may slowly dissolve with time. Nor can Warfarin reverse ischemic tissue damage either, but, may help avoid secondary thromboembolic complications that can be dangerous and even fatal. Indication Warfarin (Coumadin) is indicated for/to: • Prophylaxis, pulmonary embolism (PE), venous thrombosis and its extension, and to prevent blood clots from moving to other parts of the body. • Reduce the risk of another stroke or heart attack in clients who already have had stroke or heart attack, and to reduce the risk of death. • Prevent and treat blood clots associated with atrial fibrillation (irregular rapid heartbeat), heart-valve replacement and blood clots in lungs and legs.

Heike Sichmann is the very first wafarin patient to self-test. She has been taking warfarin and testing her coagulation status for 20 years. She feels safer taking warfarin and testing her INR at home than switching to one of the new drugs because self-testing puts her in control of her anti-coagulation management.

Gregory Piazza, MD, Division of Cardiovascular Medicine at Brigham and Women’s Hospital (BWH), discusses what patients need to know when taking anticoagulants or blood thinners. Anticoagulants or blood thinners are used to treat patients with a number of cardiovascular diseases. Most commonly, anticoagulants are used as atrial fibrillation treatment for irregular heart rhythm. Anticoagulants are also used to treat patients who have undergone heart valve repair and have mechanical heart valves. Anticoagulants are also used for patients who've experienced blood clots in either the veins or the arteries. In this video, Dr. Piazza discusses: • Types of anticoagulants including warfarin and novel oral anticoagulants (rivaroxaban, apixaban, edoxaban, and dabigatran) • Importance of medication adherence while taking anticoagulants • Laboratory monitoring of the International Normalized Ratio • Side effects of warfarin and novel oral anticoagulants (rivaroxaban, apixaban, edoxaban, and dabigatran) • Drug and food interactions associated with anticoagulant therapy • Activity restrictions and anticoagulant therapy • Discontinuing anticoagulant therapy before surgery • Benefits and risks of non-warfarin anticoagulants Learn more about cardiovascular care at Brigham and Women’s Hospital: http://www.brighamandwomens.org/cardiovascularmedicine Read the What you Need to Know about Anticoagulant Therapy video transcript: http://www.brighamandwomens.org/Departments_and_Services/medicine/services/video-transcripts/what-you-need-to-know-about-anticoagulant-therapy-transcript.aspx

(Visit: http://www.uctv.tv/) Anticoagulant medications have been in use for many years for the treatment and prevention of blood clots associated with different disease states. Safe management requires a delicate balance between preventing or treating a blood clot and avoiding any bleeding complications from the anticoagulant drugs. The availability of new drugs may offer some advantages. Steve Kayser, Professor Emeritus Department of Clinical Pharmacy at UCSF, discusses the use of anticoagulant medications, their differences, their benefits and their risks. Recorded on 06/26/2014.
