Constipation

Dehydration – know the signs (which we do lol) Older people who are dehydrated – confusion, more tired Kids eyes – sunken when dehydrated Baby's fontanels impacted Increased HR – tachycardia Skin turgor – decreased

Constipation

IBS-C

constipation

Used during straining to pass a hardened stool. May cause serious problems with individuals who have heart failure, cerebral edema, hypertension and CAD Causes increased intra-abdominal pressure and increased intrathoracic pressure which decreases venous return. Temporary bradycardia, decreased cardiac output and a transient drop in arterial pressure. Then when the patient relaxed there is a decreased in thoracic pressure and a sudden flow of blood flow to the heard which causes distension and in increase in heart rate.

Valsalva Manoeuvre

Will increase the pressure – pushing Not good for HF Bradycardia, syncope (fainting) Sudden flow that goes back to the heart – that is what people can’t handle

Valsalva Manoeuvre

Poor fluid intake Meds Lack of exercise Mental health Changes in routine Chronic laxative use Resisting the urge Lack of fiber

Gastro-enteritis

An autoimmune disease that includes Crohn’s disease and ulcerative colitis (UCI) Characterised by idiopathic inflammation and ulceration. Multiple factors are involved in the etiology of IBD (environmental factors, genetics, immune function) Commonly occur during the teenage years and early adulthood and have a second peak from ages 50 – 70. Unpredictable periods of remission interspersed with episodes of acute inflammation Debilitating.

IBS

Can affect any area of the GI tract Systemic autoimmune disorder All layers of the bowel walls Diarrhea and ABD pain Discontinuous skip lesions Deep ulcerations with thickening of the bowel Cobblestoning of mucosa Can have malabsorption and nutritional deficiencies May have severe weight loss Electrolyte imbalances

Crohn’s

Rectum and the colon Inflammation is diffuse Involves the mucosa and submucosa. Spreads proximally in a continuous fashion. Crypts of Lieberkuhn develop abscesses Bloody diarrhea and ABD Pain Complications include hemorrhage, perforations, toxic megacolon Increased risk of colorectal cancer Extraintestinal manifestations

Ulcerative Colitis

Granulation tissue (makes it thicker & shorter area) – less surface area Major symptom – bloody diarrhea (many times) 10-30 Dehydration, can lose weight, absorption problems, ulcers – risk of perforations, toxic megacolon (bigger, not effective) Most common complications: Bleeding, inflammation, megacolon Megacolon complication – perforation Increased risk of colorectal cancer –need to be monitored, regular scopes Diet - Iron supplements, rich diet due to poor absorption, high calories Systemic manifestations – mostly related to malabsorption, extra supplements, electrolyte imbalances need to be fixed, lactose free diet

Ulcerative Colitis

Happens from mouth to anus Systemic autoimmune, associated w a gene Normal and abnormal areas in GI Mucosal edema – looks like cobblestone Cramping, tenderness, distension, fever, fatigue Systemic – can have arthritis due to the immune system & malabsorption, clubbing can occur (vascular changes) Chronic findings are not a priority finding – e.g. clubbing Lots of weight loss Peritonitis is not uncommon Dairy free diet Low residue roughage and fat Surgery is used in patients with severe symptoms that are unresponsive to therapy and in those with life-threatening complications – surgery is NOT curative in this condition. Malnutrition is a big reason for surgery Fistulas Carconoma

Crohn’s

In the older client with UC, the distal colon is usually involved (proctitis). In the older client with Crohn’s disease, the colon rather than the small intestine tends to be involved. There is less recurrence of Crohn’s disease in older clients treated with surgical resection. The degree of inflammation associated with both conditions tends to be less in the older adult than in the younger client.

hepatitis

antibody to this virus, show up as immunoglobulin G, show up as acute hepatitis anorexia, nausea vomiting, jaundice, last 4-6 weeks (15-50 days) Fecal and oral transmission Past response/response from vaccination – you get immunoglobulin effect IG-G; lifelong immunity w that one

Hepatitis A

can live outside the body for 7 days Needle stick injury can cause this Can be spread from mum to baby, IV drug use, sexually transmitted infection as well IG-M – acute infection. But sub named according to the type of hepatitis Chronic infection >6m HPSAG (I think?) – causes more inflammation of the liver, try and prevent any kind of complications & progression – at risk for cancer, hepatocellular cancer Decrease the viral load Minimize symptoms and progression – drugs will decrease HBV virus but not get rid of it Acute – not much treatment, symptom management

Hepatitis B

Spread IV drug use, sharing contaminated needles Used to be seen w blood transfusions Linked to high risk sex behaviours, perinatal Causes a lot of long term liver damage Antibodies to HCV does not indicate immunity – have to test differently, find out if it’s active or not Assess the viral load Chronic lifelong, lifelong fatigue Long term inflammation, you have scarring, the cirrhosis

Hepatitis C

needs hepatitis B to survive

Include cystitis, urethritis, pyelonephritis E.Coli is the most common pathogen Predisposing factors include tumours, stones, urinary retention, foreign bodies functional disorders and factors compromising immune response

Urinary tract infection

Inflammation of the urethra

Urethritis

Inflammation of the urinary bladder Characterized by pain, urgency, frequency, hematuria

Cystitis

Inflammation of the renal parenchyma and the collecting system usually caused by infection.

Pyelonephritis

is the leading cause of UTI

E.Coli

____ has these 3 areas Urethritis – often seen w STIs. * Cystitis – bladder infection. Pyelonephritis – inflammation of kidneys.

UTI

______ & _______ – sudden onset for pain, STI one of main causes. Kidney stones can also cause this. Strictures, tumours, any growth. Problems w immune system. Diabetes w high glucose (bacteria loves sugar), lots of sugar in bladder. Cloudy urine – pyuria WBC showing up in urine

Urethritis & Cystitis

Can be classified as: Upper or lower urinary tract infection Initial or recurrent Complicated or uncomplicated Unresolved bacteriuria or bacterial persistence

UTIs

upper UTI If UTI is not treated – complications: kidney damage, chronic kidney damage, lose kidney function leading to further renal disease

Pyelonephritis

urge incontinence can be a complication

Chronic UTIs

becomes an issue diet, can lead to chronic pyelonephritis – can cause kidney to shrink & not be as functional

Chronic kidney stones

Initial UTI, recurrent UTI, complicated UTI (gone someplace else), resistant to medications, complicated

Classifications of UTIs

Most common cause I bacterial infection, but fungi, protozoa or viruses can infect the kidney. Symptoms include, chills, malaise, fever, flank pain, vomiting and symptoms of lower urinary tract infections. Antibiotic either inpatient or outpatient depending on the severity. Can lead to urosepsis, shock and death of undiagnosed and untreated.

Acute Pyelonephritis

Inflammation – susceptible to infection in little pockets, causing abscesses

Pyelonephritis

Acute – stricture & backflow, urine not completely emptying, infection that travels upwards, kidney stones, symptom: people feeling like they have the flu (nausea, vomiting, fever, chill, malaise, tenderness)

Acute Pyelonephritis

lab work is monitored to see kidney function, regular kidney tissue is damaged will be replaced by scar tissue

Chronic Pyelonephritis

A term used to describe a kidney that has become shrunken and has lost function owing to scarring or fibrosis. It usually occurs as the outcome of recurring infections involving the upper urinary tract Can lead to end stage renal disease of both kidneys are involved.

Chronic Pyelonephritis

sepsis caused by infections of the urinary tract, including cystitis, or lower urinary tract and bladder infections, and pyelonephritis, or upper urinary tract and kidney infections. Will eventually go into shock if untreated.

Urosepsis

Inflammation of the urethra Causes Bacterial or viral infection Trichomonas and monilial infection (especially in women) Chlamydia Gonorrhea (especially in men)

Urethritis

The result of obstruction and subsequent rupture of the periurethral glands into the urethral lumen with epithelialization (regrowth of tissue) over the opening of the resulting periurethral cavity More common in women than in men They occur mostly in the area of the periurethral glands

Urethra diverticula

Chronic, painful inflammatory disease of the bladder Characterized by symptoms of urgency, frequency, and pain Bladder pain syndrome or painful bladder syndrome Assessment focuses on characterization of the pain associated with interstitial cystitis. Data collection includes a bladder log or voiding diary kept over a period of at least 3 days to determine diurnal voiding frequency and patterns of nocturia.

Interstitial cystitis

Rarely a primary lesion It is usually secondary to TB of the lung. In a small percentage of clients with pulmonary TB, the tubercle bacilli reach the kidneys via the bloodstream. Onset occurs 5–8 years after the primary infection.

Renal TB

Glomerulonephritis Acute post-streptococcal glomerulonephritis Goodpasture’s syndrome Rapidly progressive glomerulonephritis Chronic glomerulonephritis Nephrotic syndrome

IMMUNOLOGICAL DISORDERS OF THE KIDNEYS

An immune related inflammation of the glomeruli. Proteinuria, hematuria, decreased urine production and edema. Elevated serum urea and creatinine can be present. Wbc, rbs and cast are present in the urine.

glomerulonephritis

Most common in children and young adults - but all age groups can be affected Occurs 5 – 21 days after an infection of the pharynx or skin by nephrotoxic strains of GrouP A B-hemolitic streptococci. Generalized body edema, hypertension, oliguria, hematuria and proteinuria. Treatments consists of managing the symptoms – diuretics, antihypertensives, diet changes, REST

Acute Poststreptococcal Glomerulonephritis

Is an autoimmune disease characterized by circulating antibodies against glomerular and alveolar basement membrane. Primary target organ is the kidney, but the lungs are also involved Rare disease that is seen mostly in young male smokers Circulating antiGBM antibodies are diagnostic of this syndrome.

Goodpasture's syndrome

Glomerular disease associated with rapid, progressive loss of renal function over days to weeks Renal failure may occur within weeks to months, in contrast to chronic glomerulonephritis, in which it develops insidiously and progresses over many years. Clinical manifestations include hypertension, edema, proteinuria, hematuria and RBC casts.

RAPIDY PROGRESSIVE GLOMERULONEPHRITIS

A syndrome that reflects the end stage of glomerular inflammatory disease Most types of glomerulonephritis and nephrotic syndrome can eventually lead to _______

Chronic glomerulonephritis

Describes a clinical course that can be associated with a number of disease conditions. Occurs when the glomerulus is excessively permeable to plasma protein - proteinuria – which leads to low plasma albumin and tissue edema

Nephrotic syndrome

Includes any anatomical or functional condition that blocks or impedes the flow of urine. Congenital or acquired. Causes are either intrinsic, extrinsic or functional.

Obstructive uropathies

Nephrolithiasis – crystals precipitate to form stones which lodge within the urinary system Calculus – stone Lithiasis – sone formation. Pain, hematuria, renal colic, N&V, Type of stone formation is affected by metabolic, dietary, genetic, climatic lifestyle and occupational influences.

Urinary tract calculi

Major categories of Stones Calcium phosphate, calcium oxalate, uric acid, crystine struvite (magnesium-ammonium phosphate) Diagnosis Urinalysis, urine cultures, ultrasound, cystoscopy, CT, (inserting dye to see how it comes thru kidneys) IVP Analysis of the stones – break up stone & assess, may be diet related then needs diet changes

Urinary tract calculi

Two approaches are used for the management of _______ 1. management of the acute attack- pain management, infection n management 2. Directed at evaluation of the stone formation and the prevention of further development of stones. Treatment –surgery, lithotripsy, diet, medications,

renal lithiasis

PLAN Relieve pain Relieve obstruction Educate client on prevention.

Nursing management: renal calculi

A rise in the incidence of traumatic renal injuries is related to an increase in the mechanization and speed of transportation and to the increase in violent crimes and injuries.

Renal trauma

Nephrosclerosis Renal artery stenosis Renal vein thrombosis

renal vascular problems

A vascular disease of the kidney characterized by sclerosis of the small arteries and arterioles of the kidney, resulting in renal tissue destruction. Benign nephrosclerosis Malignant (accelerated) nephrosclerosis

Nephrosclerosis

Partial occlusion of one or both renal arteries and their major branches A major cause of abrupt-onset hypertension

Renal Artery Stenosis

An embolus occurring in the renal vein Symptoms include flank pain, hematuria, or fever, or nephrotic syndrome

Renal Vein Thrombosis

Polycystic kidney disease ** Medullary cystic disease Alport’s syndrome

Hereditary Renal Diseases

Most common genetic disease in Canada Multiple cysts are present Enlarging cysts damage surrounding tissue Two forms of polycystic kidney disease Adult form – autosomal dominant disorder Childhood form – rare autosomal recessive disorder

Polycystic Kidney Disease

A hereditary disorder that occurs in two forms: Autosomal recessive form associated with renal failure before age 20 Autosomal dominant form associated with renal failure after age 20

Medullary cystic disease

Also known as chronic hereditary nephritis Two forms (1) Classic Alport’s syndrome—inherited as a sex-linked (2) Nonclassic Alport’s syndrome—inherited as an autosomal trait

Alport’s Syndrome

causes Sensio neural problems, deafness, problems w eyes **

Alport’s

no deafness / eye stuff involved

Nonclassical Alport’s

Various metabolic and connective tissue disease processes may have an effect on renal function

Renal Involvement in Metabolic and Connective Tissue Diseases

Kidney cancer is increasing Occur in the cortex or the pelvis Benign or malignant No characteristic early symptoms Generalized symptoms include weight loss, weakness, anemia Classic symptoms of gross hematuria, flank pain and a palpable mass are those of advanced disease.

Urinary tract tumours

6th most common type of cancer is Canadians Most common tumor of the urinary tract is the transitional cell carcinoma of the bladder. Symptom of gross, painless hematuria is the most common finding.

Bladder cancer

Diagnosis is done with a urinary log, urine residuals, U/A, urine cultures, ultra sounds, IV, CT Pelvic muscle strength testing, Bladder and sphincter testing. Treatment depends on the type but can consist of bladder routines, catheterizations, muscle floor therapies, biofeedback, incontinent pads, condom catheters, electric simulation. Drugs Muscarinic Receptor Antagonist and Anticholinerchics A-Adrenergic Antagonists Tricyclic Antidepressants Calcium channel blockers Hormone therapy

Urinary incontinence and retention

outside urethra

Urostomy

common medication used for spasms

Ditropan

not used for bladder spasms
