Select the correct statements. (Note that there may be more than one correct statement.)Group of answer choicesThrombolytic substances dissolve existing blood clots but cannot prevent their formation.Heparin cannot be absorbed from the gastrointestinal tract and therefore it is an injectable anticoagulant.One of the reasons Warfarin should not be administered in pregnancy is that it crosses the placenta and therefore may cause cerebral haemorrhage in the fetus during delivery.Heparin and warfarin effectively inhibit platelet aggregation.

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

How does heparin prevent the clotting of blood?Multiple ChoiceBy binding to calcium ionsBy depleting the blood of plateletsBy inhibiting the formation of prothrombin activator and the action of thrombin on fibrinogenBy interfering with the formation of thrombin and fibrinogen

A client has refused a prescribed injection of subcutaneous heparin. Which initial action should the nurse take?A. Document the refusalB. Notify the primary healthcare provider (PHCP)C. Review the client's most recent platelet countD. Inquire with the client about the refusal
