NUR 328 EXAM 3: ANEMIA
Classic anemia symptoms
-Fatigue -Weakness -Dyspnea -Pallor
Vitamin B12 (Cyanocobalamin)

anemia
-disorder involving too few red blood cells (RBCs) or ineffective RBCs that can alter the blood's ability to carry oxygen -Reduced oxygen-carrying capacity-hypoxemia
pernicious anemia:
-type of megaloblastic anemia characterized by lack of vitamin B12 secondary to low production of intrinsic factor by gastric cells -vitamin B12 must be replaced by IM injection or nasal spray because it cannot be absorbed through the gastrointestinal tract
schedule an appointment to measure hemoglobin twice a week for at least 2 to 6 weeks.

Ferrous Sulfate
Action: -elevate the serum iron concentration -then either converted to hemoglobin or trapped in reticuloendothelial cells for storage and eventual release and conversion into a usable form of iron for RBC production
Epoetin alfa
Action: acts like the natural glycoprotein erythropoietin to stimulate the production of RBCs in the bone marrow
Vitamin B12 (Cyanocobalamin)
Adverse effects: -HYPOkalemia -Hydroxocobalamin has been associated with itching, rash -peripheral edema -heart failure -nasal irritation
C. vasoconstriction, platelet aggregation, and conversion of prothrombin to thrombin
Blood coagulation is a complex reaction that involves A. vasoconstriction, platelet aggregation, and plasminogen action. B. vasodilation, platelet aggregation, and activation of the clotting cascade. C. vasoconstriction, platelet aggregation, and conversion of prothrombin to thrombin. D. vasodilation, platelet inhibition, and action of the intrinsic and extrinsic clotting cascades
Ferrous Sulfate
Contraindications: -Hemochromatosis (excessive iron) -hemolytic anemias, -normal iron balance
Epoetin alfa
Indication: -anemia -anemia associated with renal failure and for patients on dialysis -anemia associated with AIDS therapy -for anemia associated with cancer chemotherapy when the bone marrow is depressed and the kidneys may be affected by toxic drugs
ferrous sulfate
Iron Preparations PT drug
Folic Acid
Should be combined with B12 Prevents neural tube defects during pregnancy Used with alcohol use disorder AE- bronchospasm DI- large doses may decrease affects of anticonvulsants
VITAMIN K
The nurse is caring for a 73-year-old client receiving warfarin. When the nurse performs the initial shift assessment, the nurse observes blood in the client's urinary drainage bag. After reporting the observation to the physician, which substance will the nurse likely administer?
Iron supplement
The nurse is caring for a client who is receiving epoetin alfa. What adjunct treatment will the nurse expect the health care provider to order for this client?
for treatment of anemia associated with renal failure.
The nurse would expect the physician to prescribe epoetin alfa (Epogen) as the drug of choice A. for acute blood loss during surgery. B. to replace blood loss from traumatic injury. C. for treatment of anemia during lactation. D. for treatment of anemia associated with renal failure.
TRUE
Warfarin typically takes 3 days to achieve its onset of action.
B. to decrease the production of vitamin K clotting factors in the liver.
Warfarin, an oral anticoagulant, acts A. to directly prevent the conversion of prothrombin to thrombin. B. to decrease the production of vitamin K clotting factors in the liver. C. as a catalyst in the conversion of plasminogen to plasmin. D. immediately, so it is the drug of choice in emergency situations
aPTT
What laboratory value will the nurse prioritize when providing care for a client prescribed intravenous heparin?
"I should use aspirin to control my arthritis pain."
While preparing a client for discharge, the nurse teaches about the proper use of warfarin, which has been prescribed by the physician. Which statement by the client indicates that additional teaching is required?
ferrous sulfate
interactions: -absorption decreases preparations are taken with antacids, tetracyclines(spaced at least 2 hours apart) -decrease anti-infective if these drugs are taken because of a decrease in absorption (should be administered at least 2 hours apart)
-deferasirox tftr -deferiprone -deferoxamine mesylate
medications for iron toxicity
Epoetin alfa
take IV or Sub-Q
Central Nervous System Stimulants
-Used clinically to treat both attention deficit disorders and narcolepsy -Calm hyperkinetic children and help them focus -Redirect and excited the arousal stimuli from the reticular activating system -RAS - deep in the brain stem -Lots of different drugs -Older drugs have more systemic side effects -Newer drugs are more centrally acting and don't have the side effects that the older drugs have
Iron deficiency anemia
-low RBC count with low iron available because of high demand, poor diet, or poor absorption; treated with iron replacement -Most common type of anemia worldwide -Nutritional iron deficiency -Metabolic or functional deficiency -Manifestations when serum Hgb decreased to 7 or 8 gm/dl
Ferrous Sulfate
Adverse effects: -Staining (skin/teeth) -Hypotension -Iron toxicity (causing coma and even death) -anaphylactic reactions
Epoetin alfa
Adverse effects: -headache -HTN -edema -Chest Pain -fatigue -asthenia -dizziness -potential for serious seizures
