Ethics definition
addresses questions such as the following: How should I behave? What actions should I perform? What kind of person should I be? What are my obligations to myself and to fellow humans? Ethical judgments are concerned with values. The goal of an ethical judgment is to choose that action or state of affairs that is good or right in the circumstances.
first line of treatment for postmenopausal osteoporosis
alendronate (70mg/week) of risendronate (25mg/wk or 150mg/month) also consider zoledronate (5mg q12months) to decrease risk of adverse GI effects and to increase adherence
Cerebral blood flow (CBF)
amount of blood in mL passing through 100g of brain in one min that is monitored and influenced by autoregulation
Tumors can be classified by
anatomic site, histology (severity) or extent of disease (staging; extent and spread)
Health effects associated with air pollution
asthma, CVD (HTN), cancer, immunological effects and reproductive effects (birth defects/infant death and neuro problems)
Autoregulation
automatic adjustment in diameter of the cerebral blood vessels by the brain to maintain a constant blood flow during changes in arterial blood pressure; its purpose is to provide for brains metabolic needs and maintain cerebral perfusion pressures
extend of disease classification of tumor (staging AND extend & spread)
based on anatomic extend of disease rather than on cell appearance staging: (a) 0: Cancer in situ (b) I: Tumor limited to tissue of origin; localized tumor growth (c) II: Limited local spread (d) III: Extensive local and regional spread (e) IV: Metastasis extend and spread (TMF): (a) TNM staging cannot be applied to all malignancies (like leukemia) (b) Anatomic extent of disease is based on 3 parameters: (i) Tumor size and invasiveness (T) (ii) Spread to lymph nodes (N) (iii) Metastasis (M) (c) The higher the M number, the more extensive the metastasis. (d) T1, T2 ect. Description of primary tumor based on size and/or invastion into nearby structures, the higher the T number, the larger the tumor and/or the more it has grown into the nearby tissues. (e) The higher the N number, the more extensive the lymph node involvement.

extraarticular manifestations
(can affect almost every organ) i) Rheumatoid Nodules: (1) Rheumatoid nodules develop in about half the patients with RA.17 Rheumatoid nodules appear subcutaneously as firm, nontender, granuloma-type masses. They are often located on bony areas exposed to pressure, such as the fingers and elbows. Nodules at the base of the spine and back of the head are common in older adults. Treatment is usually not needed. However, these nodules can break down, similar to pressure ulcers. Cataracts and vision loss can result from scleral nodules. Nodular myositis and muscle fiber degeneration can cause pain similar to that of vascular insufficiency. In later disease, nodules in the heart and lungs can cause pleurisy, pleural effusion, pericarditis, pericardial effusion, and cardiomyopathy. ii) Cataracts and vision loss iii) Muscle fiber degeneration = pain (similar to vascular insufficiency) iv) Nodules in heart and lungs = pleurisy, pleural effusion, pericarditis, pericardial effusion, cardiomyopathy v) Sjogren's Syndrome- diminished lacrimal or salivary secretions (1) Sjögren's syndrome(SHOW-grins) can occur by itself or in conjunction with other arthritic disorders, such as RA and SLE. Affected patients have diminished lacrimal and salivary gland secretion, leading to a dry mouth; burning, itchy eyes with decreased tearing; and photosensitivity vi) Felty Syndrome - enlarged spleen and low WBC = risk of infection (1) Felty syndrome is rare but can occur in patients with long-standing RA. It is characterized by an enlarged spleen and low white blood cell (WBC) count. Patients with Felty syndrome are at increased risk of infection and lymphoma. (2) Flexion contractures and hand deformities cause diminished grasp strength and affect the patient's ability to perform self-care tasks. Depression also may occur. However, it is unclear if the patient becomes depressed from struggling with chronic pain and disability, or if depression is part of the autoimmune disease process.18 vii) Hand deformities, decreased grasp strength viii) Depression

Legal in New Mexico, Oregon, Vermont, Washington
a)Normal ICP
1. Volume in skull made up of brain tissue, blood, cerebrospinal fluid (CSF) 2. Hydrostatic force measured in the brain CSF compartment 3. Volume remains constant
Increased ICP Complications
1. compression of brainstem causes an upset in the process of the hypothalamus/pituitary--> SIADH--> high levels of ADHD in body cause retention of water--> hyponatremia and hypo-osmolity--> LOW URINE OUTPUT, INCREASED BODY WEIGHT, AND SYMPTOMS OF HYPONATREMIA (cramping/pain/weakness) 2. Diabetes insipidus (d/t deficiency of production or secretion of ADH or a decreased renal response to ADH-->INCREASED URINE OUTPUT AND PLASMA OMSOLALITY --> fluid/electrolyte imbalances 3. Herniation (brain tissue forcibly shifts downward due to increased ICP that forces the shift from an area of high pressure to an area of less pressure (spinal column) (spinal column = vaccuum)
Compensatory mechanisms for HF (3)
1. neurohormonal response a) renin-angiotensin-aldosterone system (RAAS) maintains homeostasis to promote sodium/fluid retention to increase BP (but overtime, it actually causes symptoms of HF) b) sympathetic nervous system activated in response to decreased SV/CO--> release of catecholamines--. vasoconstriction--> increased HR (chronotropic) and myocardial contractility (inotropy) *overtime, this increases workload, preload (volume), and oxygen 2. ventricular dilation: heart enlarges to increase volume of blood (Frank-Starling law: increased contraction leads to increase CO and dilation occurs as an adaptive mechanism to cope with increasing blood volume *overtime, elastic elements become overstretched and cannot contract effectively 3. Ventricular hypertrophy: increased muscle mass and wall thickness in response to overwork and strain (occurs slowly for muscles to thicken) *overtime, muscle has poor contractility, requires more oxygen, and has poor coronary circulation, prone to dysrhythmias
Complications of HF (5)
1. pleural effusion d/t excess accumulation in pleural cavity from increasing pressure in pleural capillaries --> dyspnea, cough, chest pain 2. dysrhythmias (d/t enlargement of heart which changes electrical pathways), afib promotes thrombus formation within the atria--> stroke 3. left ventricular thrombus: enlarged LV and decreased CO combine to increase the risk of thrombus formation in LV which can decrease contractility/CO/perfusion --> stroke 4. Hepatomegaly: RF causes liver to become congested with venous blood--> liver cells die--> fibrosis --> cirrhosis 5. renal failure: decreased CO that accompanies chronic HF results in decreased perfusion to the kidneys and can lead to renal insufficiency or failure
TAA incidence and symptoms
6-10/100,000, 20% generic, men and women equally, more common with increasing age sx: depend on the location -compression of adj structures: chest pain, SOB, cough, hoarseness, dysphagia -ascending aorta: aortic regurgitation and HF -superior vena cava: edema of the face, neck and arms

Respect for autonomy in ethics
Based on human dignity and respect for individuals, autonomy requires that individuals be permitted to choose those actions and goals that fulfill their life plans unless those choices result in harm to another.
DMARDs in treatment of RA
Because irreversible joint changes can occur as early as the first year of RA, HCPs aggressively prescribe disease-modifying antirheumatic drugs (DMARDs). These drugs may slow disease progression and decrease risk of joint erosion and deformity. The choice of drug is based on disease activity; the patient's functional level; and lifestyle considerations, such as the wish to become pregnant.
What is biomonitoring

What act regulates the air pollution from point and non-point sources?
Clean Air Act
Distributive justice
Distributive justice requires that there be a fair distribution of the benefits and burdens in society based on the needs and contributions of its members. This principle requires that, consistent with the dignity and worth of its members and within the limits imposed by its resources, a society must determine a minimal level of goods and services to be available to its members.

Types of HF
LEFT SIDED HF: most common, results from either inability of LV to empty during systole OR inability to fill during diastole *left sided can be classified as systolic, diastolic, or mixed 1. systolic failure (HFrEF): results from an inability of the heart to pump blood (decreased EF less than 45%) which causes the LV to become dilated and hypertrophied--> low SV and CO which cause increase in end diastolic volumes and pressures--> pulmonary congestion and edema as it backs up into lungs 2. diastolic failure (HFpEF): inability of ventricles to relax and fill during diastole due to stiff ventricles (d/t HTN)--> decreased filling ventricles/SV/CO--> pulmonary congestion 3. MIXED: seen in dilated cardiomyopathy (DCM) where poor systolic function is further compromised by a dilated LV that is unable to relax--> poor EF <35%, high pulmonary pressures, biventricular failure (both ventricles are dilated and have poor filling and emptying capacity RIGHT SIDED: when RV fails to pump effectively, fluid backs up into venous system causing peripheral edema, ab ascites, hepatomegaly, JVD -most common cause is Left sided HF

leading cause of death in the US
heart disease most common reason for hospital admission for those over 65years old annual cost of 40 billion dollars
heart failure definition
heart is unable to pump enough blood to meet demand which causes intravascular and interstitial volume overload and poor tissue perfusion -caused by a deficient in either ventricular filling (diastolic function)*preserved EF* or ventricular ejection (systolic function) *reduced EF*
pathophysiology of heart failure
heart tries to compensate by enlarging (heart stretches), developing more muscle mass (cells get bigger), pumping faster -BVs also narrow to keep BP up -body diverts blood away from less important organs -usually affects left side of heart first -these compensatory mechanisms mask HF until these fail

risk factors for breast cancer
i) Age and gender (women 99%; >50yrs majority and increases in incidence around 60yrs) iii) 1st degree relative iv) Personal history of colon cancer, endometrial cancer, ovarian cancer. Personal history significantly increases risk of breast cancer, risk of cancer in other breast, and recurrence. v) Menstrual history: early menarche (before 12yrs), late menopause (after 55) increases ris vi) Full term pregnancy after age 30, nullparity (prolonged exposure to unopposed estrogen) vii) Atypical epithelial hyperplasia of breast tissue: biopsy U Hyperplasia is an abnormal overgrowth of cells but rarely presents with a "lump". increases risk 4-5x. It is usually seen on imaging and diagnosed via biopsy. viii) Breast Density: more connective tissue than fatty tissue, which can sometimes make it hard to see tumors on a mammogram ix) Weight gain & obesity after menopause: fat cells store estrogen which increase the likelihood of developing breast cancer x) Radiation (damages DNA) xi) Alcohol consumption
Drug therapy for for advanced/metastatic prostate cancer
i) Androgen Deprivation (hormone) therapy (ADT) (1) Prostate cancer growth is largely dependent on presence of androgens (2) Tumors become resistant within a few years so watch PSA levels (3) Risk for cardiovascular side effects, osteoporosis & fractures (meds may be prescribed to decrease bone mineral loss (Reclast, Evista) (4) Medications will either inhibit synthesis or block the androgen receptors ii) Chemotherapy (1) Reserved for when the cancer progresses despite other treatments (2) Goal: Palliative care iii) Combination (ADT & Chemo) iv) Radium - 223: reserved for bone metastases (1) dichloride (Xofigo) In most men with metastatic castration-resistant prostate cancer—prostate cancer that no longer responds to hormone therapy—the cancer spreads (metastasizes) to the bones. Bone metastases can cause intense pain, weakness, and bone fractures, greatly impairing quality of life—and in some cases causing death. (2) Several drugs have been approved by the Food and Drug Administration (FDA) to prevent pain and fractures in patients with bone metastases, but none of these drugs improves the survival of men with prostate cancer. v) Orchiectomy (1) Surgical removal of testes *gold standard for androgen deprivation* as there are no side effects to be managed (2) Low cost, rapid relief of bone pain from metastases (3) Usually shrinks prostate and relives urinary obstructions seen in later stages (4) Side Effects: weight gain and loss of muscle mass, depression dt physical changes (5) Performed rarely because it cannot be reversed

post-operative complications of open aneurysm repair
i) Cardiac (prevalence of CAD in Vascular pts) (1) MI-most common is prevalent in vascular patients; patients can have cardiac stress due to hemodynamic changes with aortic cross-clamping and de-clamping. (2) CHF: Due to prevalence of CAD; surgical blood loss worsens morbidity. (3) Arrhythmias: related to an underlying cause such as hypoxemia, MI, or electrolyte imbalance. ii) Pulmonary (1) Atelectasis: Due to decreased lung function or incisional pain. The goal is to re-inflate the alveoli to assist in oxygenation and prevent pneumonia. iii) GI/GU (1) Renal failure: Multiple causes from surgery-suprarenal occlusion can decrease renal blood flow by 80%, the blockages can result in renal hypoperfusion. Ureteric injury can occur during dissection and arterial repair and passage of the aortic graft can cause compression of iliac artery (2) Ischemic colitis/perforation: occurs in the first 24-28 hours post-op. Ischemia and colonic perforation=multi-system organ failure. Most often caused by inadequate blood supply to the sigmoid colon and rectum from marginal collateral mesenteric flow. (3) Prolonged Ileus: due to bowel manipulation and fluid sequestration. (4) Aortoenteric fistula: Due to erosion of graft into small bowel, most often involves duodenum. iv) Graft occlusion & LE ischemia: Due to embolization from manipulation of the aorta, an occluded graft, or hypoperfusion. v) Compartment syndrome: Prolonged ischemia from acute occlusion or clamp time. Pressure in the muscle builds to dangerous levels, preventing blood flow to nerve and muscle cells and causing damage. Can cause permanent disability if not corrected vi) Hemorrhage: most common are residual anticoagulants, leakage from suture lines, retroperitoneal bleed. vii) Graft infection: Risk is greatest at implantation. Caused by skin flora, GI tract flora, infected lymph, bacteria plaque of diseased vessel viii) Incision infection ix) Paraplegia: most concerned with TAA repairs. Risk is 10x higher after an emergent repair. Due to hypoperfusion and reperfusion injury-results from prolonged aorta clamp
Pharmacologic therapy

Drug therapy in Breast Cancer Treatment
i) Chemotherapy: use of cytotoxic drugs to destroy cancer cells. (1) A combination of drugs is usually superior to the use of a single drug. Combination treatment is beneficial because the drugs have different mechanisms of action and work at different parts of the cell cycle. (2) Before and after surgery, chemotherapy is usually given for 3 to 6 months. (3) However, when a patient has metastasis, chemotherapy may be given for the rest of the patient's life. ii) iii) Trastuzumab (Herceptin) (1) Immunotherapy - targets cells and alters gene expression (kills from inside): use of cytotoxic drugs to destroy cancer cells. (1) A combination of drugs is usually superior to the use of a single drug. Combination treatment is beneficial because the drugs have different mechanisms of action and work at different parts of the cell cycle. (2) Before and after surgery, chemotherapy is usually given for 3 to 6 months. (3) However, when a patient has metastasis, chemotherapy may be given for the rest of the patient's life. ii) Tamoxifen citrate or toremifene (Fareston), and fulvestrant (Faslodex) (Oral)à Interferes with estrogen activity (1) Estrogen receptor blocker (2) Tamoifen= choice therapy in ER-positive patients with all stages of breast cancer (also used in high risk premenopausal and postmenopausal women to prevent breast cancer) iii)
Key points in managing a concussion during the acute phase
i) Child/adolescent-validated assessment and symptom scales should be used ii) The expected duration of symptoms is < 4 weeks iii) Prolonged recovery is defined as > 4 weeks iv) A brief period of cognitive and physical rest should be followed v) Individualized approach vi) Early sub-threshold exercise is associated with improved recovery patterns and outcomes vii) A graduated return to learn and return to physical activity plan is crucial viii) All schools should be encouraged to have a concussion policy and should offer appropriate academic support. ix) Children and adolescents should not return to sport until they have successfully returned to school. Early introduction of symptom-limited physical activity is appropriate and encouraged x) Partnership with multi-disciplinary team xi) Management should be individualized xii) Symptom-limited aerobic exercise xiii) A targeted PT program in patients with cervical spine or vestibular dysfunction should be considered xiv) A collaborative approach, including cognitive behavior therapy, to assist with any undiagnosed or new onset/persistent mood or behavioral issues should be considered
RA pathophys
i) Chronic, systemic autoimmune disease ii) Inflammation of connective tissue in synovial joints iii) Marked by periods of remission and exacerbation iv) Cause: Unknown (1) Autoimmune, genetics, environment v) Antigen -> triggers formation of IgG ->autoantibodies form = rheumatoid factor (RF). RF combines with IgG to form immune complexes & deposit on synovial membranes ->activates inflammation. Neutrophils are attracted -> they release enzymes that damage cartilage and thicken synovial lining. vi) The exact cause of RA is unknown. However, it probably results from a combination of genetics and environmental triggers. An autoimmune etiology is currently the most widely accepted theory, suggesting changes of RA begin when a genetically susceptible person has an initial immune response to an antigen. Although a bacterium or virus has been proposed as a possible antigen, no infection or organism has been identified to date. Starts with an antigen (probably not the same in all patients) à triggers formation of an abnormal immunoglobulin G (IgG). RA is marked by autoantibodies to this abnormal IgG. The autoantibodies are known as rheumatoid factor (RF). They combine with IgG to form immune complexes and deposit on synovial membranes à activates inflammation. Neutrophils are attracted and they then release enzymes that damage the cartilage and thicken the synovial lining. vii) Other inflammatory cells include T helper (CD4) cells, which stimulate cell-mediated immune responses. Activated CD4 cells cause monocytes, macrophages, and synovial fibroblasts to secrete the proinflammatory cytokines interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor (TNF). These cytokines drive the inflammatory response in RA.
Diagnostic tests for Colorectal cancer
i) DRE reveals nodular, fixed prostate gland (1) Abnormal prostate may feel hard, nodular, and asymmetric ii) PSA used to diagnose, stage, monitor, usually 55-69yrs (1) Most men are diagnosed by elevated levels of PSA (glycoprotein produced by the prostate above 4ng/mL) (2) Many men will live and die with prostate cancer, but will not die from it iii) An elevated level of prostatic isoenzyme of serum acid phosphatase (prostatic acid phosphatase [PAP]) is another indicator of prostate cancer, especially if the cancer has spread outside of the prostate. With advanced prostate cancer, serum alkaline phosphatase is increased as a result of bone metastasis. iv) Transrectal ultrasonography v) Urinalysis vi) Cytoscopy vii) Bone scan, MRI, CT Grade and stage determine prognosis

Stages of Death (and nursing interventions)
i) Denial: First stage (1) Initial awareness of impending death& deny the reality of the situation (5) Nursing care and interventions: to accept the individual's reactions and to provide an open door for honest dialogue ii) Anger: Second stage (1) Feeling that nothing is right (2) Difficult for individuals around the dying person (3) Unfilled desires and unfinished business (4) Family may feel guilt, embarrassment, grief, or anger in response to the dying person's anger (5) Nursing care and interventions (a) The nurse should not take the anger personally, but provide structure and continuity, which provides a sense of security. Allow the patient to maintain control as much as possible. The nurse may need to share the experience with a colleague. iii) Bargaining: Third stage (1) Postponement of the inevitable (2) Promises in return for an extension of life (3) Most bargains are made with God and usually kept as secret (4) Nursing care and interventions at this stage (a) The nurse should be available to listen and allow the patient to share his or her thoughts and feelings. iv) Depression: Fourth stage (1) Reality of the dying process is emphasized (2) Many losses can lead to depression (3) Usually a silent depression (4) Interest in prayer and desire for clergy (5) Nursing care and interventions during this stage (a) The nurse should allow the expression of sorrow and support periods of silence as well as respect the desire of the patient to be alone at times. The nurse should not try to cheer up the patient. Referrals to spiritual or religious leaders may be appropriate. v) Acceptance: Fifth stage (1) Struggling ends and relief ensues (2) Possibility of this being a final rest to gain strength for the long journey (3) Come to terms with death and gain a sense of peace (4) Nursing care and interventions during this stage (a) The nurse should support the patient's choice of selective contacts. The nurse should help simplify the environment with what is most important to the patient and provide support for family members

i) Diagnose: Bone Scan, CT Scan, MRI, xray (stage joint damage) (1) Joint space narrows as disease advances, look for osteophytes ii) Labs = Not used with OA iii) Synovial Fluid Analysis: used to rule out other types of arthritis (inflammatory) Clear, yellow= no inflammation iv) Nursing Assessment: (1) Joint Deformity, Presence of Nodes, knee and/or hip alignment (2) Pain, tenderness, stiffness, crepitation (3) Level of Disability, ROM (4) Ability to perform ADL's
interprofessional care for OA
i) Drug Therapy (1) Mild (a) Acetaminophen (b) Topical Agents: Capsaicin Cream, Voltaren gel, Aspercreme (2) Moderate (a) Low Dose NSAIDs (b) Salicylate (aspirin- some patient prefer but not as common now) (3) Corticosteroids (a) Intraarticular Injections (up to 4) (b) Systemic - not needed with OA (4) Hyaluronic Acid Injections -knee OA (5) DMARDs: Disease-Modifying Antirheumatic Drugs ii) Surgery (1) Only for loss of function, unmanaged pain or decreased independence (2) Arthroscopy or Joint Replacement
Biopsies in breast cancer (4)
i) FNA biopsy (fine needle aspiration) is performed by inserting a needle into a lesion to sample fluid from a breast cyst, remove cells from intercellular spaces, or sample cells from a solid mass. Before the procedure, the breast area is first locally anesthetized. Then the needle is placed into the breast, and fluid and cells are aspirated into a syringe. Three or four passes are usually made. If the results are negative with a suspicious lesion, an additional biopsy may be necessary. ii) A core (core needle) biopsy involves removing small samples of breast tissue using a hollow "core" needle. For palpable lesions, this is accomplished by fixing the lesion with one hand and performing a needle biopsy with the other. In the case of nonpalpable lesions, stereotactic mammography, ultrasound, or MRI image guidance is used. Stereotactic mammography uses computers to pinpoint the exact location of a breast mass based on mammograms. With ultrasound, the radiologist or surgeon watches the needle on the ultrasound monitor to help guide it to the area of concern. Because a core biopsy removes more tissue than an FNA, it is more accurate. iii) Vacuum-assisted biopsy is a version of core biopsy that uses a vacuum technique to help collect the tissue sample. In core biopsy, several separate needle insertions are used to acquire multiple samples. During vacuum-assisted biopsy, the needle is inserted only once into the breast, and the needle can be rotated, which allows for multiple samples through a single needle insertion. iv) Minimally invasive breast biopsies have become the standard of care for diagnosing abnormalities found either on imaging studies or through clinical examination. However, in some cases an excisional biopsy is recommended. An excisional biopsy is performed in an operating room
Pathophysiology of colorectal cancer
i) Most (about 95%) of CRC cases are adenocarcinomas (which is cancer that begins in glandular or secretory cells that are found in tissue that line internal organs) ii) Begin as type of polyp called an adenoma (2 types of polyps: hyperplastic and adenomas; adenomas develop into cancer) iii) Typically, few effects until spread iv) Metastasis to regional lymph nodes common v) Seeding of tumor: into muscularis mucosae and eventually gains access to lymph nodes vi) Since venous blood leaving the colon and rectum flows through the portal vein and the inferior rectal vein, the liver is a common site of metastasis
nursing care of OA
i) Rest and Joint Protection ii) Heat and Cold iii) Nutrition iv) Exercise v) Avoid Smoking vi) Transcutaneous Electrical Nerve Stimulation (TENS) vii) Complementary and Alternative Therapies (1) Herbs (2) Nutritional Supplements (3) Glucosamine Chondroitin (4) Movement therapies (5) Acupuncture (6) Massage viii) GOALS: maintain joint function, protect joint, achieve independence in self-care, and drug/nondrug pain relief
clinical manifestations of RA
i) Fatigue, Anorexia & Weight loss: The onset of RA is typically insidious. Nonspecific manifestations such as fatigue, anorexia, weight loss, and generalized stiffness may precede the onset of joint symptoms. ii) General Stiffness (1) After activity & in morning (2) Stiffness becomes more localized in the following weeks to months. Specific joint involvement is marked by pain, stiffness, limited motion, and signs of inflammation (e.g., heat, swelling, tenderness). Joint symptoms occur symmetrically and often affect the small joints of the hands (PIP and MCP) and feet (MTP). Larger peripheral joints such as wrists, elbows, shoulders, knees, hips, ankles, and jaw may also be involved. The patient typically experiences joint stiffness after periods of inactivity. Morning stiffness may last from 60 minutes to several hours or more, depending on disease activity. MCP and PIP joints are typically swollen. In early disease, the fingers may become spindle shaped from synovial hypertrophy and thickening of the joint capsule. Joints are tender, painful, and warm to the touch. As the disease progresses, inflammation and fibrosis of the joint capsule and supporting structures may cause deformity and disability. Muscle atrophy and tendon destruction cause one joint surface to slip past the other (subluxation). Metatarsal head dislocation and subluxation in the feet may cause pain and walking disability (Fig. 64-3, D). Ulnar drift ("zig-zag deformity"), swan neck, and boutonnière deformities are common in the hands (Fig. 64-4). iii) Joint stiffness (usually second) (1) Symmetric Involvement (2) Small Joints (3) "Spindle fingers", "zig-zag" & Subluxation (4) Tender, painful, warm iv) Precipitation Event? (1) Stressful event or work stress (2) Infection (3) Physical exertion (4) Childbirth (5) Surgery (6) Emotional Upset
adverse side effects to treatments of osteoporosis
i) GI distress: abdominal pain, nausea, vomiting and esophageal and gastric irritation ii) Important to maintain an upright posture for 30-60mins and renal toxicity so check serum Cr before administering
Assessment of RA
i) History and Physical ii) Complete blood cell (CBC) count iii) Erythrocyte sedimentation rate (ESR)à inflammation iv) C-reactive protein (CRP)à inflammation v) Rheumatoid factor (RF) occurs in 80% of patients with RA and higher in active disease vi) Antibody to citrullinated peptide (anti-CCP): often more accurate than RF (use for early diagnosis and treatment) vii) Antinuclear antibody (ANA) increased in 20-30% of RA patients (part of the autoimmune response- reaction to the antigen) viii) X-ray studies of involved joints (soft tissue swelling and demineralization) ix) Synovial fluid analysis: early: slightly, straw colored
reasons for declining vaping since 2019
i) Increased public awareness of the risk associated with THC-containing e-cigarette, or vaping, product use as a result of the rapid public health response, Removal of vitamin E acetate from some products & Law enforcement actions related to illicit products
Screening guidelines for breast cancer
i) Mammogram: X-rays to visualize internal breast structure ii) Starting at age 45 & Annually until 54 yrs iii) >55yrs = biannually until health conditions worsen and life expectancy is <10yrs iv) Consistent Self-Breast Exams
synovial fluid analysis related to RA
i) Management (1) Nutritional and weight management counseling (2) Therapeutic exercise (3) Psychologic support (4) Rest and joint protection, use of assistive devices (5) Heat and cold applications ii) Drug Therapy (Table 64-3) (1) Disease-modifying antirheumatic drugs (DMARDs) (2) Intraarticular or systemic corticosteroids (3) Nonsteroidal antiinflammatory drugs (NSAIDs) (4) Biologic response modifiers (BRMs) iii) Positive RF occurs in approximately 80% of adults with RA, and titers rise during active disease. iv) ESR and C-reactive protein (CRP) are general indicators of active inflammation. An increase in antinuclear antibody (ANA) titers is also seen in 20% to 30% of patients with RA.3 v) Testing for the antibodies to citrullinated peptide (anti-CCP) is also important in the diagnosis of RA. Levels of anti-CCP are more specific than RF for RA. In some cases, testing may allow an early, accurate diagnosis.3 vi) Synovial fluid analysis in early disease often shows slightly cloudy, straw-colored fluid with many fibrin flecks. The enzyme MMP-3 is increased in the synovial fluid of the patient with RA, and it may be a marker of progressive joint damage. The WBC count of synovial fluid is elevated. i) X-rays alone are not diagnostic of RA. They may show only soft tissue swelling and possible bone demineralization in early disease. A narrowed joint space, articular cartilage destruction, erosion, subluxation, and deformity are seen in later disease.
Diagnosing TB
i) Mantoux TB Skin Test (TST) (1) Positive >5cm *Positive does not determine if they are latent or active (just determines antibodies)* ii) Interferon-gamma release assays (IGRAs) Blood Tests measure immune response to TB bacteria (1) QuantiFERON-TB Gold (2) T-SPOT test iii) Sputum specimens (1) 3 consecutives (2) Smear is not definitive, but culture IS (isolates bacteria, but takes up to 8 weeks) iv) Chest x-ray: cannot be used alone
Surgeries in Breast Cancer Treatment
i) Mastectomy (1) Radical: breast, chest muscle and nodes (2) Simple (total): entire breast (3) Segmental (4) Modified radical: breast and axillary nodes (keeps pectoralis muscle) (5) Axillary node dissection (6) Nipple-sparing: areola are left in place (a) Women who have a small cancer near the outer part of the breast, with no signs of cancer in the skin or near the nipple ii) Lumpectomy or Breast conservation (if less than 5cm and used in combination with chemo) (1) involves removal of the entire tumor along with a margin of normal surrounding tissue (Fig. 51-6, A). In some cases, it may take two to three additional surgeries to remove all the cancer from the margins. After surgery, radiation therapy is delivered to the entire breast, ending with a boost to the tumor bed. If the risk for recurrence is high, chemotherapy may be administered before radiation therapy iii) Breast reconstruction (1) Individual preference (2) Timing of reconstruction (3) Several procedures iv) Axillary Lymph Node Analysis (1) Sentinel lymph node biopsy (SLNB) is the preferred standard for axillary lymph node analysis and staging. It was described on p. 1212. However, if the sentinel lymph node cannot be identified, or if the node is positive for cancer, ALND may have to be performed.
Complications of TB
i) Military TB: Spread of TB bacteria to distant organs--> Fever, cough, hepatomegaly or splenomegaly ii) Pleural TB: Extrapulmonary TB (TB outside of lungs)--> Unilateral, exudative pleural effusion (cloud fluid buildup: congestion, cough and diminished breath sounds) AND Empyema: pus pockets from infection *need chest tube* iii) Organ involvement: spine (obstruction of discs/vertebrae, abdomen (peritonitis), lymph nodes, kidneys, urogenital tract, etc
Genetics involved in Prostate Cancer
i) No single gene causes prostate cancer ii) Prostate Cancer Categories (1) Sporadic: 75% (by chance, after birth) (2) Familial: <20% (genes + environment) (3) Hereditary (inherited): 5-10% (passed down in a family from one generation to next) (a) (1) three or more first-degree relatives with prostate cancer, (2) prostate cancer in three generations on the same side of the family, and (3) two or more close relatives (father, brother, son, grandfather, uncle, nephew) on the same side of the family diagnosed with prostate cancer before age 55. (b) Only genetic testing can determine whether a man has a genetic mutation. However, no genetic tests are available to determine if a man is predisposed to developing prostate cancer. (c) Having a family history does not mean that a man will develop prostate cancer; it indicates that he has an increased risk.
Causes of drug-resistant TB
i) Nonadherence to full course of treatment ii) Prescription of wrong treatment iii) Drugs for treatment not available iv) Drug quality is poor
Clinical manifestations of breast cancer
i) Nontender lump in breast (hard palpabale) ii) Most often in upper outer quadrant (where glandular tissue lie) iii) Abnormal nipple discharge (usually unilateral and may be clear or bloody) iv) Rash around nipple area v) Nipple retraction vi) Dimpling of skin vii) Change in nipple position viii) Usually painless ix) Peau d'orange (d/t plugging of dermal lymphatics) x) Infiltration, dimpling (pulling in) of overlying skin xi) *Most often found by patient
Paget's breast cancer
i) Paget's (PAJ-its) disease of the breast is a rare form of breast cancer. Paget's disease of the breast starts on the nipple and extends to the dark circle of skin (areola) around the nipple. ii) Paget's disease of the breast occurs most often in women older than age 50. Most women with Paget's disease of the breast have underlying ductal breast cancer, either in situ — meaning in its original place — or, less commonly, invasive breast cancer. Only in rare cases is Paget's disease of the breast confined to the nipple itself.
Medicare coverage for testing of osteoporosis (every 2 years) for the five populations:
i) Persons with vertebral abnormalities ii) Persons with primary hyperparathyroidism iii) Women who are estrogen deficient or at clinical risk for osteoporosis iv) Persons taking long-term glucocorticoids v) Persons being monitored for response to treatment with an FDA- approved osteoporosis medication
Phyllodes
i) Phyllodes (full-OH-deez) tumors of the breast are rare, accounting for less than 1% of all breast tumors. The name "phyllodes," which is taken from the Greek language and means "leaflike," refers to that fact that the tumor cells grow in a leaflike pattern. Other names for these tumors are phylloides tumor and cystosarcoma phyllodes. Phyllodes tumors tend to grow quickly, but they rarely spread outside the breast. ii) Phyllodes tumors can occur at any age, but they tend to develop when a woman is in her 40s. Benign phyllodes tumors are usually diagnosed at a younger age than malignant phyllodes tumors. Phyllodes tumors are extremely rare in men.
Nursing interventions for prostate cancer
i) Promote urinary elimination (1) Assess degree of incontinence and effect on lifestyle (2) Teach Kegel exercises (3) Teach methods to control dampness, odor (a) Do not attempt to prevent accidental voiding by restricting fluids (4) Absorbent pads worn inside underwear (5) Refer to PT or continence specialist (6) Explore options such as external collection device (7) Encourage verbalizing feelings about impact of incontinence ii) Promote communication related to sexual dysfunction (1) Surgical treatment may cause ED (2) Assess pretreatment sexual function (3) Teach client about actual or potential effects of therapy on sexual function (4) Provide opportunity for client and partner to discuss implications and concerns (5) Discuss medical, surgical treatments for ED (6) Refer for sexual counseling as appropriate iii) Promote effective pain management (1) Assess intensity, location, quality of pain (2) Provide optimal pain relief (3) Teach client and family noninvasive methods of pain control
surgery for prostate cancer
i) Prostatectomy (1) Simple (2) Radical- entire gland, seminal vesicles and neck of bladder because the cancer tends to be in different locations within the glad (3) Retropubic: a low midline abdominal incision is made to access the prostate gland, and the pelvic lymph nodes can be dissected (4) Perineal: an incision is made between the scrotum and anus (5) Suprapubic i) Nerve-Sparing Procedure: Near the prostate gland are neurovascular bundles that maintain erectile functioning. The preservation of these bundles during a prostatectomy is possible while still removing all of the cancer. Nerve-sparing prostatectomy is not indicated for patients with cancer outside of the prostate gland. Although the risk of ED is reduced with this procedure, there is no guarantee that potency will be maintained. ii) Cryotherapy: is a surgical technique for prostate cancer that destroys cancer cells by freezing the tissue. It has been used both as an initial treatment and as a second-line treatment after radiation therapy has failed. A TRUS probe is inserted to visualize the prostate gland. Probes containing liquid nitrogen are then inserted into the prostate. Liquid nitrogen delivers freezing temperatures, thus destroying the tissue. The treatment takes about 2 hours under general or spinal anesthesia and does not involve an abdominal incision.
ID team approach to RA
i) Registered Nurse (RN) (1) • Administer drug therapy as ordered. (2) • Teach patient and caregiver about medications, including increased risk of infection with disease-modifying agents. (3) • Assess disease impact on quality of life and joint function. (4) • Assess pain intensity and administer analgesics as ordered. Assess patient response. (5) • Develop program for rehabilitation and education with the interprofessional team. (6) • Teach patient about need for balance of rest and activity, with use of joint protective strategies. ii) Unlicensed Assistive Personnel (UAP) (1) • Assist patient with passive ROM of affected joints. (2) • Notify RN about patient complaints of pain. (3) • Assist patient with self-care needs. iii) Physical Therapist (1) • Assess patient's current mobility and need for assistance. (2) • Establish exercise regimen and teach patient to perform exercises safely. (3) • Coordinate PT with RN so that patient can receive timely analgesia. (4) • Discuss home environment with patient and identify possible modifications to facilitate disease management (e.g., bathroom on first level to avoid stairs). iv) Occupational Therapist (1) • Assess impact of patient's condition on ability to perform ADLs. (2) • Instruct patient in use of assistive devices (e.g., long-handled reacher, long-handled shoe horn) to facilitate self-care without increasing stress on joints. (3) • Discuss home environment with patient and identify possible modifications to facilitate role performance (e.g., kitchen modifications for meal preparation). v) Social Worker (1) • Assess need for durable medical equipment (e.g., walker). (2) • Assess psychosocial and financial impact of disease. Arrange vocational retraining if needed
Stages of Colorectal Cancer
i) Stage 0 cancer has not grown beyond the mucosal layer. ii) Stage I cancer has grown beyond the mucosa into the submucosa, but no lymph nodes are involved. iii) Stage II cancer has grown beyond the submucosa into the muscle but there is no lymph node involvement or metastasis. iv) Stage III cancer is any tumor with lymph node involvement but no metastasis. v) Stage IV cancer is any tumor with lymph node involvement and metastasis
stages of RA
i) Stage I: Synovitis, high WBC (synovial fluid) 5-60k (1) Synovial membrane swelling with excess blood (2) Membrane containing small areas of lymphocyte infiltration (3) High WBC counts in synovial fluid (5000-60,000/µL) Due to swarm of neutrophils at site (4) X-ray results: soft tissue swelling, possible osteoporosis, but no evidence of joint destruction ii) Stage II: Increased joint inflammation, narrowing of joint space (1) Increased joint inflammation, spreading across cartilage into joint cavity (2) Signs of gradual destruction in joint cartilage (3) Narrowing joint space from loss of cartilage iii) Stage III: Pannus formation, cartilage erodes, bone is exposed (1) formation of synovial pannus (2) Joint cartilage becomes eroded, bone exposed (3) X-ray results: extensive cartilage loss, erosion at joint margins, possible deformity iv) Stage IV: end-stage, inflammation subsides, loss of joint function (1) End-stage: inflammatory process subsides (2) Loss of joint function (3) Formation of subcutaneous nodules

diagnostic criteria for RA
i) Synovitis that is not related to another disease ii) Joint Involvement iii) Serology iv) Acute Phase Reactants v) Duration of Symptoms more than 6 weeks vi) What kind of specialist does a patient with RA see? (1) A doctor or a team of doctors who specialize in care of RA patients should diagnose and treat RA. This is especially important because the signs and symptoms of RA are not specific and can look like signs and symptoms of other inflammatory joint diseases. Doctors who specialize in arthritis are called rheumatologists, and they can make the correct diagnosis.
clinical manifestations of OA
i) Systemic = NONE (no fever, fatigue or organ involvement) ii) Joints (1) Range: Mild discomfort à Significant disability (2) Pain is primary symptom and reason for seeking care (3) Early Stages: pain relief with rest (4) Later Stages: pain at rest, pain with barometric pressure, disability, joint stiffness after period of rest, overactivity can cause inflammation, *crepitation, grating sensation, bone spurs (5) Asymmetrical (typically) (6) Weight-bearing joints are commonly involved iii) Deformity (1) Heberden's Nodes: distal finger joints due to osteophytes and loss of joint space, red, swollen and tender (2) Bouchard's Nodes: proximal finger joints; red, swollen and tender (3) Bowlegged: Knee OA; medial joint arthritis (4) Knock-kneed: Knee OA; lateral joint arthritis (5) Uneven Leg Length: Hip OA

types of breast cancer 4
i) Tissue Type (in situ within the duct) (1) Ductal carcinoma (epithelial lining of milk ducts) (2) Lobular carcinoma (epithelial lining of milk glands) (3) Other: inflammatory (rare and aggressive, blocks lymph flow), Paget's disease (infects ducts around nipple then spreads), Phyllodes tumor (leaf-like tumor) ii) Invasiveness (invading through wall of duct) (1) Noninvasive (in situ) (2) Invasive (spreading) iii) Hormone Receptor and Genetic Status: biopsy reveals if there are certain proteins that are estrogen or progesterone receptors (because hormones attach and fuel growth) (1) Cancers are called hormone receptor-positive or hormone receptor-negative based on whether or not they have these receptors (proteins). Knowing the hormone receptor status is important in deciding treatment options iv) HER-2 Genetic Status (human epidermal growth factor receptor 2): HER2-positive breast cancer is a breast cancer that tests positive for a protein called human epidermal growth factor receptor 2 (HER2), which promotes the growth of cancer cells. v) In about 1 of every 5 breast cancers, the cancer cells have a gene mutation that makes an excess of the HER2 protein. HER2-positive breast cancers tend to be more aggressive than other types of breast cancer.
OA causes
i) Trauma: injuries can happen to bones that interrupt the blood supply (dislocations and fractures); this can cause damage to the bones and ultimately causes osteoarthritis because the healing isn't entirely perfect and the stress put on that bone can be uneven. This causes the bone to rub together and break down. ii) Mechanical Stress: repetitive activities like sports cause cartilage deterioration iii) Inflammation: repeated responses to local inflammation can impact cartilage health. iv) Joint Instability: if surrounding supportive structures of a joint are damaged, then there is uneven stress on that joint v) Neurologic Disorders: abnormal movements that result from loss of sensation or reflexes can cause cartilage deterioration vi) Skeletal Deformities: congenital or aquired conditions also impact cartilage (this is where you might see osteoarthritis in children) vii) Hematologic or Endocrine Disorders: bleeding into a joint cavity can impact the cartilage viii) Drugs: certain drugs can stimulate collagen digesting enzymes in the joints (corticosteroids)
Radiation therapy for prostate cancer
i) Used as a primary treatment or palliative treatment ii) Delivered by external beam: most widely used method of delivering radiation treatments for men with prostate cancer. This therapy can be used to treat patients with prostate cancer confined to the prostate and/or surrounding tissue. Patients are usually treated on an outpatient basis 5 days a week for 4 to 8 weeks; each treatment lasts only a few minutes. iii) Brachytherapy (interstitial implants of radioactive seeds into prostate gland allowing for higher radiation doses directly in the tissue while sparing the surrounding tissue such as the rectum and bladder. (1) Seeds are placed in the prostate gland with a needle through a grid template guided by TRUS to ensure accurate placement of seeds
Genetics & Colorectal Cancer
i) Very small portion of CRC are caused by inherited gene mutations ii) Familial adenomatous polyposis (FAP), attenuated FAP (AFAP), and Gardner syndrome are caused by inherited changes in the APC gene. The APC gene is a tumor suppressor gene iii) Lynch Syndrome: 3% (Hereditary Nonpolyposis Colorectal Cancer (HNPCC) - germline variants in DNA MMR genes iv) Peutz-Jeghers Syndrome- STK11 (LKB1) gene, tumor suppressor gene v) MYH-associated polyposis (MAP) - MYH gene, changes how the cell proofreads and fixes errors when cells divide
BRMs (biologic response modifiers) in treatment of RA
i) also called biologics or immunotherapy) are also used to slow disease progression in RA. These drugs are classified based on their mechanism of action (Table 64-3). (1) They can be used to treat patients with moderate-to-severe who have not responded to DMARDs. They can also be used alone or in combination therapy with a DMARD such as methotrexate (most common DMARD)
Inflammatory breast cancer
i) develops rapidly, making the affected breast red, swollen and tender. ii) Inflammatory breast cancer occurs when cancer cells block the lymphatic vessels in skin covering the breast, causing the characteristic red, swollen appearance of the breast. iii) Inflammatory breast cancer is considered a locally advanced cancer — meaning it has spread from its point of origin to nearby tissue and possibly to nearby lymph nodes. iv) Inflammatory breast cancer can easily be confused with a breast infection, which is a much more common cause of breast redness and swelling. Seek medical attention promptly if you notice skin changes on your breast
Direct observation therapy of TB
i) hospitalized for short term and given follow up care for direct therapy) (1) Observe and document individual clients taking TB drugs (2) Prevents antibiotic resistance in community (3) Ensures effective treatment of individuals
Anatomic site classification of tumor

indications for surgical intervention for aneurysm
if symptomatic, rapidly enlarging aneurysm greater than 5.5cm
biomarkers related to RA
increased biomarkers can predict extraarticular manifestations i) Biomarkers: measurable substances that can predict the presences of a specific disease, infection or environmental exposure. We can even use biomarkers to track progress, treatment effectiveness and predict outcomes of diseases. They are very objective. They really do not tell us how the patient "feels" or is tolerating the plan of care or progression of the disease- that is very subjective but important when assessing biomarkers.

Acute nicotine exposure
raises blood pressure and spikes your adrenaline, which increases HR
Tumor necrosis factor inhibitors in treatment of RA
reduce inflammation and can stop disease progression by targeting an inflammation-causing substance called Tumor Necrosis Factor (TNF).It binds to TNF in circulation before TNF can bind to the cell surface receptor. Thus they inhibit the inflammatory response. This drug is given as a subcutaneous injection. There are several different TNF inhibitors that are used for RA.
bone marrow and stem cell transplantation in cancer treatment

volume or preload (amount of ventricular stretch at the end of diastole) pressure or afterload (heart working against blood to eject it during systole) contractility: strength of muscle contractions HR increased Ejection fraction (amount of blood pumped by left ventricle with each beat)
When is autoregulation ineffective?
when MAP <70 or >150 if low, then the CBF will decrease and cerebral ischemia will occur if high, the CBF will stop constricting--> dilate--> increase flow
Macrophages can be activated by _________________ and secrete ______________
y-interferon which is produced by T cells to become nonspecifically lytic for tumor cells (1) cytokines, interleukin-1, TNF, and colony-stimulating factors (CSFs) (2) IL-1 and presentation of the processed antigen à T cell activation and production (3) Alpha interferon augments the killing ability of NK cells (4) TNF causes hemorrhagic necrosis of tumors and exerts cytocidal or cytostatic actions against tumor cells (5) CSFs regulate the production of various blood cells in bone marrow and stimulate various WBCs (6) B cells can produce specific antibodies that bind to tumor cells (antibodies are often detectable in patient's serum and saliva)
DO promoting agents increase odds of cancer?
yes because promotion occurs during the second stage which is the reversible proliferation of altered cells which increases likelihood of additional mutations
