Antidote for heparin
What action by the patient requires you to re-educate them about how to administer Heparin?Ī. You are observing the patient administer their scheduled dose of Heparin to confirm that the patient knows how to do it correctly. Your patient is being discharged home and will be required to self-administer injectable Heparin. Heparin can NOT be administered orally….only subq or IV.ġ0. Heparin can be administered orally, intravenously, or subcutaneously. Heparin works to affect the intrinsic pathways of clotting.ĭ. Select all the TRUE statements about the medication Heparin:Ĭ. aPTT values should be around 60-80 seconds to achieve a therapeutic response for Heparin.ĩ. If the aPTT is less than 60 seconds, the dose would need to be increased and a bolus may be needed. Most Heparin protocols dictate that the nurse would hold the infusion for 1 hour and to decrease the rate of infusion. Any aPTT value greater than 80 seconds places the patient at risk for bleeding. The aPTT is 105 seconds, which is too high. Hold the infusion for 1 hour and decrease the rate per protocol because the aPTT is too high. Increase the drip rate per protocol because the aPTT is too low.ĭ. Continue with the infusion because no change is needed based on this aPTT.ī. What is your next nursing action per protocol?Ī. A patient, who is receiving continuous IV Heparin, has an aPTT of 105 seconds. This is considered a (approximate…varies in labs) normal aPTT level in someone who is NOT on Heparin.Ĩ. What is the approximate NORMAL level range for an activated partial thromboplastin time (aPTT)? If the aPTT is too high, bleeding can occur.ħ. If the aPTT is too low, blood clots can form. An aPTT should be 1.5-2.5 times the normal value range for Heparin to achieve a therapeutic effect in a patient to prevent blood clots. In order for this medication to have a therapeutic effect on the patient, the aPTT should be? A patient is receiving continuous IV Heparin. Therefore, for proper dosing to be administered, a correct weight should be used.Ħ. The nurse would want to make sure the documented weight of the patient is current and accurate. Prior to starting the medication, the nurse would ensure what information is gathered correctly before initiating the drip? A patient is ordered to start an IV continuous Heparin drip. Troponin levels are used in cardiac patients to detect a myocardial infarction.ĥ. PT and INR are used to measure clotting times in patients who are taking Warfarin (Coumadin).
It is important that the nurse collect an aPTT in 6 hours (some protocols may say 4 hours) after starting the drip. An activated partial thromboplastin time (aPTT) is used to measure clotting time in patients who are on Heparin. Collect an aPTT level in 6 hours per protocol. Collect a Troponin level in 6 hours per protocol.ĭ. Collect an INR level in 4 hours per protocol.Ĭ. Collect a PT level in 6 hours per protocol.ī. What will be your next important nursing action?Ī. You administer a bolus of Heparin and start the drip per protocol as ordered by the physician. Your patient is started on a Heparin drip. Option B and D are candidates from Heparin therapy because the patient in option B has a blood clot (Heparin can prevent it from getting bigger and developing new blood clots), and the patient in option D is at risk for developing a blood clot.Ĥ. These patients are both at risk for major bleeding if placed on an anticoagulant due to their condition (one patient is post-op from brain surgery and the other patient has ulcers that could bleed). A 43-year-old female with uncontrolled atrial fibrillation.
A 36-year-old male patient with active peptic ulcer disease.ĭ. A 45-year-old female patient with a pulmonary embolism.Ĭ. A 55-year-old male patient who is post-op day 1 from brain surgery.ī. Which patients below would be at a HIGH risk for developing adverse effects of Heparin drug therapy? Select all that apply:Ī. Therefore, this medication INDIRECTLY inhibits thrombin via antithrombin III.ģ. Heparin enhances the activation of antihrombin III, which prevents the activation of thrombin and the conversion of fibrinogen to fibrin. “It enhances the activation of antihrombin III, which prevents the activation of thrombin and the conversion of fibrinogen to fibrin.” “It prevents Factor Xa from activating prothrombin to fibrinogen.”ĭ. “It inactivates the extrinsic pathways of coagulation.”Ĭ. “It inhibits clotting factors from synthesizing Vitamin K.”ī. Which statement below BEST describes how Heparin works as an anticoagulant?Ī. Heparin is an anticoagulant that belongs to the Indirect Thrombin Inhibitors family.Ģ.
