The nurse is caring for a client who currently has a deep vein thrombosis. Which of the following medications would be administered to lyse existing clots? (Select All that Apply.)
Aspirin
Heparin
warfarin (Coumadin)
alteplase (Activase)
anistreplase (Eminase)
Correct Answer : D,E
A) Aspirin: While aspirin is an antiplatelet medication that can help prevent further clot formation, it does not have thrombolytic properties and does not directly lyse existing clots. Therefore, it is not appropriate for this purpose.
B) Heparin: Heparin is an anticoagulant used to prevent the extension of existing clots and reduce the risk of new clots forming, but it does not dissolve existing clots. It helps manage deep vein thrombosis but does not have thrombolytic activity.
C) Warfarin (Coumadin): Warfarin is an oral anticoagulant that is used to prevent new clot formation and the growth of existing clots. However, like heparin, it does not actively lyse or dissolve existing clots.
D) Alteplase (Activase): This medication is a thrombolytic agent that actively dissolves blood clots by activating plasminogen to plasmin, leading to clot breakdown. It is appropriate for use in cases of deep vein thrombosis when clot lysis is indicated.
E) Anistreplase (Eminase): Similar to alteplase, anistreplase is another thrombolytic agent used to lyse existing clots. It acts by converting plasminogen to plasmin, effectively breaking down fibrin in clots, making it suitable for the treatment of deep vein thrombosis.

Correct Answer is D
Explanation
A) Pancytopenia: While some medications can cause pancytopenia, it is not a common or direct side effect of alteplase. This condition involves a reduction in red blood cells, white blood cells, and platelets, and is not typically associated with thrombolytics.
B) Hypertension: Alteplase is not known to cause hypertension. In fact, the goal of administering alteplase in the context of a pulmonary embolism is to dissolve the clot and restore normal blood flow, which may help stabilize blood pressure.
C) Hypokalemia: This condition, characterized by low potassium levels, is not a common side effect of alteplase. There are other medications that may cause electrolyte imbalances, but alteplase itself is not typically linked to hypokalemia.
D) Internal bleeding: This is a significant risk associated with alteplase, as it is a thrombolytic agent that dissolves clots. The nurse should closely monitor for signs of internal bleeding, such as changes in vital signs, unexplained bruising, or blood in urine or stool. This is the most critical side effect to assess for in a client receiving alteplase
Correct Answer is A
Explanation
A) Losartan (Cozaar): This medication is an angiotensin II receptor blocker (ARB) and is often used as an alternative for patients who experience a cough due to ACE inhibitors. Unlike ACE inhibitors, ARBs do not typically cause a cough because they do not affect bradykinin levels, making losartan an appropriate choice for managing hypertension without the adverse effect of a persistent cough.
B) Hydralazine HCL (Apresoline): While hydralazine is an antihypertensive, it works through a different mechanism (direct vasodilation) and is not a first-line alternative for patients with a history of ACE inhibitor-induced cough. It's generally used in specific situations, such as severe hypertension or heart failure.
C) Furosemide (Lasix): This is a loop diuretic primarily used for conditions like heart failure or edema, rather than for the management of hypertension alone. It does not address the underlying hypertension in the same manner as ACE inhibitors or ARBs.
D) Metoprolol (Lopressor): This is a beta-blocker that can be used for hypertension, but it does not directly address the issue of cough related to ACE inhibitors. Switching to a beta-blocker may not be the best option if the client is specifically seeking to avoid the cough associated with ACE inhibitors.
