| Question | Answer |
|---|---|
| ferrous sulfate | iron deficiency anemia |
| Vit b12 cyanocobalamin | pernicious anemia |
| folic acid | megaloblastic anemia (decreased RBC production) |
| factor VIII | hemophilia A- clotting disorder causing increased bleeding |
| factor XI | hemophilia B- clotting disorder causing easy bruising and bleeding |
| desmopressin | mild hemophilia A (trauma induced, surgery) |
| heparin, enoxaparin | prevents DVT, PE, inhibits thrombin |
| warfarin action | prevents DVT,PE, inhibits Vit K |
| clopidogrel action | inhibits platelet aggregation |
| alteplase action | can break up clots |
| epoetin alpha action | produces RBC-erythrocytes |
| hemophilia A and B action/instructions | anaphylaxis reaction, have emergency equipment ready |
| desmopressin admin/A.E/instructions | give 30 min before surgery, can cause hyponatremia, monitor I&O and weight |
| heparin action/ A.E/ interactions | inhibits thrombin/hemorrhage, thrombocytopenia, DVT, don't give NSAIDs to renal insufficient pts |
| warfarin action/A.E/instructions | inhibits Vit K, decreases blood clot but DOES NOT rid of it, hemorrhage, toxicity (IF HAPPENS GIVE VIT K), pts should use electric razor, soft toothbrush, expect 3-5 days for full effects |
| clopidogrel admin/A.E/interactions | stop 1 week before surgery, check platelet levels, bleeding TTP, No NSAIDs or Anticoagulants |
| alteplase action/contraindications/interactions | breaks up clot, intracranial bleeding, cardiac dysrhythmias, No previous stroke within 6 months, No surgery 2-4 weeks prior |
| epoetin alfa action/A.E/instructions | produces RBC, DONT shake vial, hypertension, chest pain, headache, MI, DVT, monitor Hgb- different for cancer pts |
| protamine | use for heparin overdose |
| when should you stop heparin | platelet count under 100,000 |
| how to monitor heparin for correct admin | aPTT is 1.5-2 times clients baseline- test determines blood clotting time |
| heparin and oral warfarin together | warfarin takes 3-5 days for full effect, then discontinue heparin |
| warfarin pt discharge instructions | avoids NSAIDs, brush with soft toothbrush, ask before taking OTC drugs |
| liquid ferrous sulfate admin | drink with straw, dilute with water, take with food if needed |
| heparin treats | DVT |
| folic acid (IV) A.E | rash |
| filgrastim treats | chronic neutropenia (low WBC) |
| factor VIII contraindication | aspirin |
| warfarin daily lab tests | PT (prothrombin-protein in blood plasma that helps blood clot)/INR |
| alteplase instructions | monitor temp, limit venipunctures, assess neurologic status, apply pressure to oozing sites |
| what food is high in Vit k | mayonnaise |
| alteplase action | dissolves thrombi( blood clots) |
| filgrastim action | produces WBC-leukocytes |
| clopidogrel A.E | thrombocytopenia (petechiae), vision changes, weakness |
| Oprelvekin assess for A.E | ECG |
| aspirin action | inhibits platelet aggregation by inhibiting cyclooxygenase in platelets |
| alteplase A.E | headache |
| ferrous sulfate instructions | eat iron enriched foods, spread dosage across each day, take on empty stomach, increase dietary fiber |
| warfarin pt has rectal bleeding, administer what | Vit K |
| ferrous sulfate A.E | constipation |
| folic acid lab test for therapeutic effect | reticulocyte count- looks for amount of new RBC's |
| alteplase severe reaction administer what | aminocaproic acid- helps blood clot |
| factor IX eliminates R.F what disease | Creutzfeldt-Jakob's disease- memory loss with blurred vision or blindness, eventually causing dementia and even death |
| desmopressin A.E | edema |
| pt taking Desmopressin what electrolyte should be monitored | sodium, cause it can cause hyponatremia |
| factor VIII instructions | have emergency equipment ready |
| epoetin alfa admin | IV bolus over 1-3 min |
| epoetin alfa lab to monitor | Hgb |
| filgrastim A.E | enlarged spleen |
| what promotes warfarin effectiveness | dietary modifications |
| clopidogrel contraindications | PUD |
| administer what to ferrous sulfate toxicity | deferoxamine |
