Chapter 67: Care of Patients with Kidney Disorders Flashcards
The kidneys are responsible for
meeting the human need for urinary ELIMINATION by filtering wastes and maintaining FLUID AND ELECTROLYTE BALANCE, as well as ACID–BASE BALANCE.
Pyelonephritis
is a bacterial infection in the kidney and renal pelvis
interferes with urinary ELIMINATION
Acute pyelonephritis
active bacterial infection
involves immunity responses leading to acute tissue inflammation, local edema, tubular cell necrosis, and possible abscess formation anywhere in the kidney.
chronic pyelonephritis
repeated or continued upper urinary tract infections that occur almost exclusively in patients who have anatomic abnormalities of the urinary tract. Bacterial infection causes local (e.g., kidney) and systemic (e.g., fever, aches, and malaise) inflammatory symptoms.
Reflux
is the reverse or upward flow of urine toward the renal pelvis and kidney.
how people get pyelonephritis
organisms usually move up from the urinary tract into the kidney tissue.
Abscesses
pockets of infection can occur anywhere in the kidney
acute pyelonephritis involves
MMUNITY responses leading to acute tissue inflammation, local edema, tubular cell necrosis, and possible abscess formation
chronic inflammation in the kidney glomerular and tubular structures cause:
Fibrosis and scar tissue
filtration, reabsorption, and secretion are impaired; and kidney function is reduced
acute pyelonephritis result from
bacterial infection, with or without obstruction or reflux.
Chronic pyelonephritis usually occurs with
structural deformities, urinary stasis, obstruction, or reflux.
chronic kidney stone disease can lead to:
stones may retain organisms, resulting in ongoing infection and kidney scarring.
Drugs, such as high-dose or prolonged use of NSAIDs can lead to:
papillary necrosis and reflux.
Other causes of kidney scarring contributing to increased risk for pyelonephritis are
inflammatory responses resulting from IMMUNITY excesses with antibody reactions, cell-mediated immunity against the bacterial antigens, or autoimmune reactions.
The focus of care for pyelonephritis patients is to
manage the structural or functional abnormality that contributes to recurrent infection and inflammatory fibrosis.
pyelonephritis- Urinalysis shows
positive leukocyte esterase and nitrite dipstick test and the presence of white blood cells and bacteria.
pyelonephritis- blood cultures and labs show:
determine the source and spread of infectious organisms. Other blood tests include the WBC count and differential of the complete blood count, as well as C-reactive protein and erythrocyte sedimentation (ESR) rate to determine IMMUNITY responses and presence of inflammation
Blood urea nitrogen (BUN) and creatinine are used as baseline and to trend recovery or deterioration. Estimate of glomerular filtration rate (GFR) also is used to trend kidney function.
X-ray of the kidneys, ureters, and bladder and IV urography are performed to diagnose
stones or obstructions.
Cystourethrogram is indicated for some patients to:
define urinary tract structures and identify any defects, such as stones, obstructions to the outflow of urine, and urine reflux caused by incompetent bladder-ureter valve closure.
Cystourethrogram
is an X-ray test that takes pictures of your bladder and urethra while your bladder is full and while you are urinating.
pyelonephritis Interventions include
the use of drug therapy with antibiotics, analgesics if needed, diet and fluid therapy, and teaching to ensure the patient’s understanding of the treatment.
Other procedures to improve lower urinary tract drainage include
pyelolithotomy, nephrectomy, ureteral diversion, or reimplantation of the ureter to restore proper bladder drainage.
pyelolithotomy
surgical procedure that removes stones from the ureter or renal pelvis
nephrectomy
removal of all or part of a kidney
Acute glomerulonephritis (GN)
develops suddenly from an excess IMMUNITY response within the kidney tissues. Usually an infection is noticed before kidney symptoms of acute GN are present. The onset of symptoms is about 10 days from the time of infection.
Many causes of primary GN
infectious
secondary glomerulonephritis can be caused by
multi-system diseases, manifested as acute or chronic disease.
glomerulonephritis s/s
proteinuria, hematuria, decreased glomerular filtration rate, edema, and hypertension.
systemic or confined to the kidneys.
glomerulonephritis Urinalysis
demonstrates red blood cells and protein
glomerulonephritis renal biopsy
provides a precise diagnosis of the condition, assists in determining the prognosis, and helps outline treatment.
glomerulonephritis Interventions
focus on managing infections, fluid overload, preventing complications, and providing appropriate patient education.
glomerulonephritis ask about:
systemic diseases that alter IMMUNITY such as systemic lupus erythematosus (SLE)
changes in urine ELIMINATION patterns and any change in urine characteristics.
Mild to moderate hypertension occurs with acute GN as a result of
impaired FLUID AND ELECTROLYTE BALANCE with fluid and sodium retention
Rapidly progressive glomerulonephritis (RPGN),
a type of acute nephritis, develops over several weeks or months and causes loss of renal function.
Patients become quite ill quickly
