Select the correct statements. (Note that there may be more than one correct statement.)Group of answer choicesAtrial fibrillation is one of the risk factors for thrombus formation.Thrombolytic substances dissolve existing blood clots and therefore are the first choice of treatment in the case of haemorrhagic stroke.When detached from its site of production, a blood clot that has formed in the left atrium will most likely block a pulmonary blood vessel and therefore cause pulmonary embolism.Aspirin should not be administered in children because it may trigger post-viral encephalitis.

Which of the following is an absolute contraindication to fibrinolytic therapy?Prior intracranial hemorrhageHistory of poorly controlled hypertensionPregnancyMenses

A nurse is caring for a 39-year-old female client on a medical-surgical floor. The interdisciplinary team has determined that the client is at a risk for the development of a pulmonary embolism and has therefore implemented prophylactic measures. The client is prescribed Warfarin therapy for its anticoagulant effects. Based on the nurse's understanding of the drug, the nurse confirms that the drug has reached a therapeutic level when which of the following coagulation results are obtained?The client's baseline coagulation studies:Activated partial thromboplastin time (aPTT): 30 secondsInternational normalized ratio (INR): 1.5Prothrombin time (PT): 10 secondsCassidy RhodyID: 112703Question 6Select one:1.PT 7 seconds, INR 2.52.PT 19 seconds, INR 2.03.PT 25 seconds, INR 2.14.aPTT 35 seconds, INR 3.0
