90. What should be in the patient teaching for taking Coumadin? Such as interactions.

Avoid Aspirin, Manicure, Vitamin K. Advise the patient to limit foods high in vitamin K, such as leafy green vegetables, beans, broccoli, cabbage, cauliflower, cheese, fish, and yogurt. Vegetables with large amounts of vitamin K can interfere with the anticoagulant's effect (see Home Care Checklist: Ensuring Appropriate Vitamin K Intake Instruct patient to take medication as directed. Take missed doses as soon as remembered that day; do not double doses. Inform health care professional of missed doses at time of checkup or lab tests. Inform patients that anticoagulant effect may persist for 2-5 days following discontinuation. Advise patient to read Medication Guide before starting therapy and with each Rx refill in case of changes. •Review foods high in vitamin K (see food sources for specific nutrients). Patient should have consistent limited intake of these foods, as vitamin K is the antidote for warfarin, and alternating intake of these foods will cause PT levels to fluctuate. Advise patient to avoid cranberry juice or products during therapy. •Caution patient to avoid IM injections and activities leading to injury. Instruct patient to use a soft toothbrush, not to floss, and to shave with an electric razor during warfarin therapy. Advise patient that venipunctures and injection sites require application of pressure to prevent bleeding or hematoma formation. • Advise patient to report any symptoms of unusual bleeding or bruising (bleeding gums; nosebleed; black, tarry stools; hematuria; excessive menstrual flow) and pain, color, or temperature change to any area of your body to health care professional immediately.Patients with a deficiency in protein C and/or S mediated anticoagulant response may be at greater risk for tissue necrosis. • Instruct patient not to drink alcohol or take other Rx, OTC, or herbal products, especially those containing aspirin or NSAIDs, or to start or stop any new medications during warfarin therapy without advice of health care professional. •Advise patient to notify health care professional if pregnancy is planned or suspected or if breastfeeding. •Instruct patient to carry identification describing medication regimen at all times and to inform all health care personnel caring for patient on anticoagulant therapy before lab tests, treatment, or surgery. • Emphasize the importance of frequent lab tests to monitor coagulation factors Drug-Drug •Abciximab, androgens, capecitabine, cefotetan, chloramphenicol, clopidogrel, disulfiram, fluconazole, fluoroquinolones, itraconazole, metronidazole (including vaginal use), thrombolytics, eptifibatide, tirofiban, sulfonamides, quinidine, quinine, NSAIDs, valproates, and aspirin may ↑ the response to warfarin and ↑ the risk of bleeding. •Chronic use of acetaminophen may ↑ the risk of bleeding. •Chronic alcohol ingestion may ↓ action of warfarin; if chronic alcohol abuse results in significant liver damage, action of warfarin may be ↑ due to ↓ production of clotting factor. •Acute alcohol ingestion may ↑ action of warfarin. •Barbiturates, carbamazepine, rifampin, and hormonal contraceptives containing estrogen may ↓ the anticoagulant response to warfarin. •Many other drugs may affect the activity of warfarin. Drug-Natural Products: • St. John's wort ↓ effect. •↑ bleeding risk with anise, arnica, chamomile, clove, dong quai, fenugreek, feverfew, garlic, ginger, ginkgo, Panax ginseng, licorice , and others.

ITP is the most common thrombocytopenia of childhood, occurring most frequently in the 2- to 10-year age-group. It occurs in either acute or chronic form. As its name implies, the cause ofITP is unknown; however, it is believed to be an autoimmune response to disease-related antigens. The acute form of ITP usually follows a viral infection (such as a respiratory infection, rubella, rubeola, mumps, or chickenpox; or after infection with parvovirus B19) and is selflimiting; the chronic form has periods of remission. -symptoms: •easy or excessive bruising (purpura) — your skin naturally bruises and bleeds more easily as you age, but this shouldn't be confused with ITP •superficial bleeding into your skin that appears as a rash of pinpoint-sized reddish-purple spots (petechiae), usually on your lower legs •Prolonged bleeding from cuts •Spontaneous bleeding from nose •Bleeding gums, especially after dental work •Blood in urine or stools •Unusually heavy menstrual flow •Fatigue

MEMMLERS P. 384-385, 387 Antigens=any foreign substance that induces an immune response; they are large protein molecules-carbs and some lipids may act as antigens; normally only nonself antigens stimulate an immune response; found on surface of pathogenic organisms, transfused blood cells, transplanted tissues, cancer cells, pollen, toxins, & food. *critical feature: it stimulates the activity of certain lymphocytes classified as T or B cells Antibodies= Y-shaped proteins secreted by plasma cells (activated B cells) in response to specific antigens. B cells are 2nd class of active lymphocytes in immunity; surface receptors on B cells bind w/a specific type of antigen which exposure to the antigen stimulates the cells to multiply rapidly producing clones or plasma cells; mature cells produce antibodies against the original antigen & release them into the blood providing humotal immunity. *ALL antibodies contained in part of plasma called gamma globulin

62. What is mitral valve prolapse?

Mitral valve prolapse manifestations: -palpitations, dyspnea, chest pain, activity intolerance, syncope; midsystolic click (CK p.1578) -Mitral valve prolapse is a condition in which the two valve flaps of the mitral valve do not close smoothly or evenly. Mitral valve prolapse is also known as click-murmur syndrome, Barlow's syndrome or floppy valve syndrome -When the heart pumps (contracts) part of one or both flaps collapse backward into the left atrium. In some cases, the prolapsed valve lets a small amount of blood leak backward through the valve, which may cause a heart murmur -The most common cause of MVP is due to small, usually harmless, tumor-like growths of collagen on the valve leaflets (called myxomatous changes). Mitral valve prolapse occurs in 2 percent to 3 percent of the population. A person can be born with the genetic risk of developing MVP or it can be caused by other health problems, such as some connective tissue diseases -Many people live with this condition without symptoms but when a prolapsing valve allows blood to leak back into the atrium, this is called regurgitation. A regurgitating, (or leaky) mitral valve may need to be treated Symptoms, which in some cases may be related to leaking of the mitral valve, can include: •Chest pain (not caused by coronary artery disease or a heart attack) •Dizziness •Fatigue •Sensation of feeling the heart beat (palpitations) •orthopnea or SOB with activity (AHA website)

82. What is atrial depolarization?

PR Interval Atrial contraction

112. What is the Homan's sign?

Pain and edema occur when the vein is obstructed. The circumference of the calf or thigh may increase. Active dorsiflexion of the foot may result in calf pain. This is referred to as a positive Homans' sign and may indicate thrombophlebitis. Homans' sign is a classic but unreliable sign because it is not specific for DVT and appears in only 10% of DVT patients. Superficial thrombophlebitis may show signs of inflammation such as erythema, warmth, and tenderness along the course of the vein.

60. For a patient with chronic angina pectoris, how would you give nitroglycerin?

Place nitroglycerin tablet under tongue to dissolve (quick absorption). The client can take up to two more doses of nitroglycerin at 5-min intervals. Ati med surg 298 ◯ Immediately put one sublingual tablet under the tongue and let it dissolve. Rest for 5 min. ◯ If pain not relieved by first tablet, call 911, then take a second tablet. ◯ After 5 more minutes, take a third tablet if pain is still not relieved. Do not take more than three sublingual tablets. Ati pharm 285

114. What is a thrombocyte? memm, 288

Platelets, also called thrombocytes (THROM-bo-sites), are cell fragments that participate in blood clotting.

30. Prothrombinase occurs in the clotting process, explain it more.

Prothrombinase converts prothrombin in the blood to thrombin. Calcium is needed for this step. Thrombin, in turn, converts soluble fibrinogen into insoluble fibrin. Threads of fibrin form a meshwork that entraps plasma and blood cells to form a clot.

27. Patient with occlusion of the lower extremities has cold feet and calls the nurse for assistance, what would be a proper nursing action?

Put on socks

26. Cardiac catheterization patient has a left antecubital IV inserted, what pulse site would you palpate?

Radial pulse

107. How long after must a patient be observed after blood transfusions? med surge, 380

Remain with the client for the first 15 to 30 min of the infusion (reactions occur most often during the first 15 min) and monitor: ☐ Vital signs (then every hour afterward). ☐ Rate of infusion. ☐ Respiratory status.

4. Bradycardia EKG

Sinus bradycardia is a slow rhythm originating in the SA node. It is characterized by a pulse rate of less than 60 bpm (or even less than 50 bpm, according to some sources). Causes of sinus bradycardia include sleep, vomiting, intracranial tumors, MI, drugs (espcially digitalis toxicity), carotid sinus massage, vagal stimulation, endocrine disturbances, increased intracranial pressure, and hypothermia. When found in association with MI, it is a beneficial rhythm because it reduces myocardial oxygen demand.

72. What are the risk factors for Atherosclerosis?

Smoking, HTN, obesity, hypercholesterolemia, animal fats, sedentary life style, DM, combo of BC pills and smoking Coronary artery disease (CAD) is the term used to describe a variety of conditions that obstruct blood flow in the coronary arteries. Atherosclerosis (a common arterial disorder characterized by yellowish plaques of cholesterol, lipids, and cellular debris in the inner layers of the walls of large and medium-size arteries) is the primary cause of ASHD. The lumen (a cavity or channel within any organ of the body) of the vessel narrows as the disease progresses. Blood flow to the heart is obstructed when this process occurs in the coronary arteries. Atherosclerosis, the basic underlying disease affecting coronary lumen size, is characterized by changes in the intimal lining (the innermost layer) of the arteries. The severity of the disease is measured by the degree of obstruction within each artery and by the number of vessels involved. Obstructions exceeding 75% of the lumen of one or more of the three coronary arteries increase the risk of death. The basic physiologic changes of the atherosclerotic process result in problems with myocardial oxygen supply and demand. When the myocardial oxygen demand exceeds the supply delivered by the coronary arteries, ischemia results (Figure 48-10). The artery walls also become less elastic and less responsive to blood flow

28. What is erythropoietin?

Stimulates red blood cell production in the bone marrow. This hormone is produced when there is a decreased oxygen supply in the blood. Hypoxia stimulates the kidneys to secrete erythropoietin, prompting red bone marrow to manufacture more erythrocytes and hemoglobin. A problem with this can result in anemia.

91. What should you D/C in a patient with poor circulation in lower extremities?

Stockings or socks with elastic tops.

38. For a patent on anticoagulant therapy, when should they take their medication?

Take medication at the same time each day

64. What blood levels would you expect to find in a patient with iron deficiency anemia?

Tests for levels of hemoglobin indicate whether iron deficiency anemia (a condition of lack of iron needed to carry oxygen throughout the body) is present Confirmation of iron deficiency anemia should be undertaken if there is a low level of hemoglobin. These tests include total iron content, percent iron saturation, total iron-binding capacity, and levels of transferrin (a protein that binds and transports iron) and ferritin (the storage form of iron). Hemoglobin: The normal hemoglobin level is 14 to 18 g/dL for men and 12 to 16 g/dL for women. -Hematocrit -Ferritin -Serum Iron (Fe) -CBC *decreased RBCs or Hemoglobin *hypochromic and microcytic RBCs

78. What is ventricle depolarization?

The QRS complex represents the depolarization of the ventricles.

25. Blood returns from the lungs to the right atrium, is that correct?

The blood returns from the lungs to the LEFT atrium

101. What is the sinoatrial node? ck, 1541

The heartbeat is initiated in the sinoatrial (SA) node -located in the upper part of the right atrium, just beneath the opening of the superior vena cava. -AKA, the pacemaker. Impulses are then passed to the AV node.

67. What is a Monocyte?

Type of leukocyte (agranular) -are the largest in size; they average about 5% of the leukocytes -they lack easily visible granules; nuclei are round or curved and are not segmented -function: phagocytosis (engulfing of foreign matter) -some monocytes enter the tissues and mature into phagocytes called macrophages -2%-6%: expressed as percentage of total WBC -100-600/mm3- expressed in actual numbers X 10 to the 9th power/mm3

Weakness Decreased BP Rapid, weak, thready pulse Rapid respirations Cold, clammy skin w/ pallor Oliguria

96. Patient has flu like symptoms with petechiae in mount and legs, also chills. What is infective endocarditis?

\Endocarditis is an infection or infl ammation of the inner membranous lining of the heart, particularly the heart valves. Classifi ed on the basis of cause, it may result from invasion of an organism (infective endocarditis) or from injury to the lining. The term bacterial endocarditis has been replaced by infective endocarditis because causative organisms include fungi, chlamydiae, rickettsiae, viruses, and bacteria. The causative organisms—most commonly Streptococcus viridans, Streptococcus pyogenes, Staphylococcus aureus, Staphylococcus epidermidis, and enterococci— are deposited on the heart lining or valves. As the organism embeds into the tissue, a vegetative growth perforates the chambers or valve leafl ets. Fibrin and calciferous growths of the vegetation may ulcerate and scar the valves; or the growths may break away, causing emboli, infection, or abscess in organs where they lodge. The loss of portions of vegetative lesions into the circulation results in embolization. Systemic embolization occurs from left-sided heart vegetation, progressing to infarction of an organ (particularly the brain, the kidneys, and the spleen) and limb. Right sided heart lesions embolize to the lungs. Endocarditis may develop after cardiac surgery, which in itself is traumatic. People at risk include patients with rheumatic, congestive, or degenerative heart disease.

33. Orthopenia, orthopenic, why are they used and define?

an abnormal condition in which a person must sit or stand to breathe deeply or comfortably

granular leukocyte; eosinophils (and basophils) make up a small percentage of the white cells but increase in number during allergic reactions -stain with acidic dyes

106. What are the five DVT risk factors?

high calcium

66. What is the best position for a patient with right sided HF?

● Right-sided heart failure (cor pulmonale) ◯ Air trapping, airway collapse, and stiff alveoli lead to increased pulmonary pressures. ◯ Blood flow through the lung tissue is difficult. This increased workload leads to enlargement and thickening of the right atrium and ventricle. ◯ Manifestations include the following. ■ Low oxygenation levels ■ Cyanotic lips ■ Enlarged and tender liver ■ Distended neck veins ■ Dependent edema ◯ Nursing Actions ■ Monitor respiratory status and administer oxygen therapy. ■ Monitor heart rate and rhythm. ■ Administer medications as prescribed. ■ Administer IV fluids and diuretics to maintain fluid balance. ◯ Right-sided failure Subjective/Objective findings: ■ Jugular vein distention ■ Ascending dependent edema (legs, ankles, sacrum) ■ Abdominal distention, ascites ■ Fatigue, weakness ■ Nausea and anorexia ■ Polyuria at rest (nocturnal) ■ Liver enlargement (hepatomegaly) and tenderness ■ Weight gain *orthopneic position most comfortable*
