There are many links, notes, and resources to help other brave LPNs with the on line challenges of bridging to become a RN. This is an on-going record of the trials and triumphs of my journey to reach my goal to become a Registered Nurse via Excelsior College's Nursing Program. My journey continues as I further my education and career. I hope my notes and resources help other students on their journey.

- Trousseau's and Chvostek's signs
- Serum chloride level less than 98mEq/L confirms hypochloremia
- supportive values with metabolic alkalosis include a serum pH greater than 7.45 and a serum carbon dioxide level greater than 32 mEq/L
- Serum chloride level greater than 108 mEq/L confirms hyperchloremia
- supportive values with metabolic acidosios include a serum pH less than 7.35 and a serum carbon dioxide level less than 22 mEq/L
- Serum Phosphorus level less than 1.7 mEq/L (or 2.5 mg/dl) confirms hypophosphatemia, urine phosphorus level more than 1.3 g/24/hrs supports this
- Serum Phosphorus level greater than 2.6 mEq/L (or 4.5 mg/dl) confirms hyperphosphatemia, urine phosphorus level less than 0.9 g/24/hrs supports this
- Sodium - hyponatremia less than 135 mEq/;L hypernatremia greater than 145 mEq/L
- Disseminated Intravascular Coagulation - PT greater than 15 seconds; PTT greater than 60 to 80 seconds; fibrinogen levels less than 150 mg/sl; platelets less than 100,000; fibrin degradation products typically greater than 100 mcg/ml; and a positive D-dimer test specific for DIC
- Hemophilia Factor VIII assay reveals 0% to 25% of normal factor VIII (hemophilia A)
- hemophilia B factor IX assay shows deficiency in addition to baseline coagulation results similar to that of A
- Idiopathic Thrombocytopenic Purpura (ITP) platelet count is less than 20,000/ul; prolonged bleeding time
- Iron Deficiency Anemia decreased Hb, HCT, iron, ferritin, reticulocytes, red cell indices, transferring and saturation; absent hemosiderin, and increased iron biding capacity.
- Aplastic Anemia - bone marrow biopsy shows fatty marrow with reduction of stem cells, Fecal occult blood test is positive, decreased granulocytes, thromobocytes, and RBCs, hematuria
- Pernicious Anemia - from vitamin B mal-absorption
- Polycythemia vera - chronic myeloproliferateve disorder characterized by increased RBC mass, leukocytosis, thrombocytosis and increased Hb, common with jewish males age 40 - 60
- Rheumatoid Arthritis - antibodies attack the synnovium of the joint , then the articular cartilage and surrounding tendons and ligaments. ANA positive, elevated ESR, WBC, platelets and anemia, Rheumatoid factor test is positive
- Scleroderma - connective tissue disease, more women 30 -50 elevated ESR, positive rheumatoid factor 25% - 35% of the time, positive antinuclear antibody test. CXR - bilateral basilar pulmonary fibrosis, UA - proteinuria, microscopic hematuria, and casts
- Sickle Cell Anemia - congenital hematologic disease, inherited
- Systemic lupus erythematosus (SLE) - ANA test positive, decreased HB, HCT, WBC and platelets and an increased ESR, rheumatoid factor is positive, UA - proteinuria and heaturia. Lupus Erythematosus cell positive
- Vasculitis - inflammation and necrosis of blood vessels
- Wegener's Granulomatosis - affects medium to large vessels of upper and lower respiratory tract and kidney
- positive leukocytosis, elevated ESR, IgA, IgG; low titer rheumatoid factor; tissue biopsy shows narcotizing vasculitis with granulomatous inflammation
- Temporal arteritis - affects medium to large arteries, most connonly branches of th ecarotid artery
- decreased Hb and elevated ESR, tissue biopsy shows panarteritis with infiltration of mononucliar cells, giant cells within vessel wall, fragmentation of internal elastic lamina and proliferation of intima
- Takayasu's arteritis - AKA aortic arch syndrome
- decreased HB, leukocytosis, positive lupus erythematosus cell preparation and elevated ESR; Arteriography shows calcification and obstruction of affected vessels; tissue biopsy shows inflammation of adventita and intima of vessels and thickening of vessel wall
Plasma - liquid portion - water, protein (albumin and globulin), glucose, and electrolytes
Leucocytes- white blood cells
AB antigens - blood type
Thrombocytes - platelets clotting - contributors
Erythocytes - red blood cells - oxygen carrier
T-Cells -
killer, helper or suppressor
B-Cells -
responsible for humeral or immunoglobulin-mediated immunity
Immunoglobulin -
Immunoglobulin G (IgG) - major antibacterial and antiviral antibody
Immunoglobulin M (IgM) - first Immunoglobulin produced too large to cross membrane barriers, usually only in vascular system
Immunoglobulin A (IgA) - mainly found in body secretions, defends against pathogens on body surfaces, especially respiratory and GI tract
Immunoglobulin D (IgD) - in plasma, dominant antibody on surface of B cells mainly an antigen receptor.
Immunoglobulin E (IgE) - antibody involved in immediate hypersensitivity or allergic reactions, stimulates the release of mast cell granules which contain histamine and heparin.
- Lymphangiography - radiographic picture of lymphatic system -
- note allergies to iodine, seafood and radiopaque dyes
- possible throat irritation and flushing after dye
- NPO
- After procedure
- monitor V/S
- encourage fluids
- may have blue discolored skin, stool, and urine for about 48 hours
Hodgkin's progress - 4 stages
- Stage I - single lymph node region or single extralymphatic organ
- Stage II - two or more nodes on same side of diaphragm or in an extralymphatic organ
- Stage III - spreads to both sides of the diaphragm or in an extralymphatic organ, the spleen or both
- Stage IV - disease disseminates

ABGs
Normal Values
Values at sea level:
•Partial pressure of oxygen (PaO2) - 75 - 100 mmHg
•Partial pressure of carbon dioxide (PaCO2) - 38 - 42 mmHg
•Arterial blood pH of 7.38 - 7.42
•Oxygen saturation (SaO2) - 94 - 100%
•Bicarbonate - (HCO3) - 22 - 28 mEq/L
Note: mEq/L = milliequivalents per liter; mmHg = millimeters of mercury
At altitudes of 3,000 feet and above, the oxygen values are lower.
