Q

What is acute pyelonephritis?

Study These Flashcards
A

No signs of complications

may be treated as outpatient

oral antibiotics: 14 days

IF COMPLICATIONS:

  • hospitalized
  • IV antibiotics
  • Parenteral therapy
19
Q

What is chronic pyelonephritis

Study These Flashcards
A

suspected in patients with recurrent UTI and acute pyelonephritis

may develop hypertension

can cause chronic renal failure and or ureosepsis

20
Q

What is urosepsis?

Study These Flashcards
A

comprises at 25% of all sepsis cases

Secondary to complicated UTI or obstructive uropathy

Patients most likely to develop urosepsis include the elderly, diabetics and immunosuppressed

21
Q

What are key concepts of urosepsis?

Study These Flashcards
A

Systemic response to infection

Bacteremia: confirmed by culture

HEmodynamically unstable: supportive therapy

Immediate antimicrobial therapy

Control of complicating factors

22
Q

What is acute glomerulonephritis?

Study These Flashcards
A

Involes and allergic or immune response: priteinuria or hematuria

S&S: history sore throat, URI, strep infection in last month, smoky or coffee colored uring

Complications: edema, hypertension

Interventions: prevention infection, fluid restriction, control nausea and anorexia, plasma, no OTC

23
Q

What is chronic glomerulonephritis?

Study These Flashcards
A

Develops over a period of 20-30 years or longer

Interventions:

  • slowing progression of disease and prevent complication
  • diet changes: low protein
  • fluid intake
  • dialysis, transplantation
24
Q

What are obstructive disorders?

Study These Flashcards
A

Tumors

Strictures

Renal calculi

25
What is prostatic enlargement?
Interferes with urinary flow at the bladder neck inflammation-prostatis benign or malignant tumore Symptoms: - nocturia - poor caliber or urinary stream - overflow incontinence
26
What are the risk factors and clinical manifestations of urolithiasis
History of urologic stones Clinical Manifestations: - pain - decreased urinary output Rediographic assessment Other diagnostic tests Complications - urinary obstriction
27
What are interventions of urolithiasis?
pain control strain urine diet teaching
28
What is drug therapy?
Antibiotics and urinary antiseptics Pain management drugs: - opiod analgesics - NSAID - spasmolytic drugs
29
What is lithotripsy?
Extracorporeal shock wave lithortripsy uses sound, laser or dry shock wave energy to break the stone into small fragments Client undergoes conscious sedation Topical anesthtic cream to skin site is stone Continuous monitoring is by electrocardiography
30
What is surgical management of Lithotripsy?
Stenting Ureteroscopy Percutaneous ureterolithotomy and nephrolithotomy Open surgical procedures - preoperative care - operative procedure
31
What is postoperative care?
Routine postoperative care when procedures for assessment of bleeding, urine and adequate fluid intake Strained urine Infection prevention Prevention of obstruction
32
What is the potential for renal failure?
Prevention key with high risk groupds Limit exposure of nephrotoxic substances Compliance with therapies and regular follow-up Blood ressure control Acute vs. Chronic
33
What are the causes of acute renal failure?
PRerenal: compromise blood flow to kidneys Intrarenal: damage to kidney tissue Postrenal: obstucts urine flow after leaving nephron
34
What are the phases of acute renal failure?
Sudden onset Oluguric: no response to fluid challenge Diuretic: unable to concentrate urine Recovery: go back to normal Acute syndrome may be reversible with prompt intervention
35
What are the different drug therapies?
Phosphate biners Diuretics Antihypertensives as needed Erythropoietin
36
What are the stages of chronic renal failure?
1: at risk 2: mild, some diminshed 3: moderate, diminished renal reserve, 50% decrease RFR, no clinical findings 4: severe, renal insufficiency, 50-80%, accumulate nitrogen waste in blood, increase BUN and creatine 5: End-stage, 80-95%, decrease GFR, \>95% decreases later, multisystem failure
37
What are the clinical manifestations of CRF?
Neurologic: accumulate nitrogen waste Cardio: dysrhythemia Respiratory: anemia, destructive RBC Hematologic GI Urinary SKin Musculoskeletal Reproductive
38
What are the interventions for excess fluid volume?
monitor I&O promote fluid balance asess manifestations of volume excess - crackles in bases of lungs - edema - distended neck veins Drug therapy includes diuretics
39
What are the interventions of decreased cardiac output?
control HTN with calcium channel blocker, ACE inhibitors Instruct clinet and family to monitor BP, weight, diet and drug therapy
40
What are the risks for infection?
Meticulous skin care Preventive skin care Inspection of vascular assess site for dialysis Monitoring of vital signs for manifestations of infection
41
What are the interventions for risk for injury?
Prevent fall or injury pathologic fractures bleeding toxic effects of prescribed drugs
42
What are interventions for fatigue
Assess fo vitamin deficiency, anemia and buildup or urea Administer vitamin and mineral supplements Administer erythropoietin therapy for bone marrow production Give iron supplements
43
What are intervernetions for anxiety?
Health care team involement Clinet and family educatoin Continuity of care Encouragement of client to ask questions and discuss fears about the diagnosis of renal failure
