Q

Leukostasis

A

life-threatening complication

high leukemic WBC count in the peripheral blood: > 100,000

Blood thickens and blocks circulatory pathways

Q

Leukemia Diagnosis

A
  • WBC count: 20,000- 100,000 prior to tx
  • H&H, platelets decreased
  • bleeding time increased
  • bone marrow biopsy
  • lymph node biopsy for lymphoma
  • Lumbar puncture, PET/CT scan for leukemic cells outside blood or bone marrow

Complications of Leukemia

A

!! Neutropenia: report ANC <2000 and report temp > 37.8 (100 F) NOTIFY IF TEMP IS 99.5

!! Thrombocytopenia: greatest risk < 50,000

Q

Symptoms of diverticulitis and complications

A
  • acute pain in LLQ, distention, decreased or absent BS, nausea, vomiting, systemic symptoms of infection

older adults: afebrile, normal WBC, possible abd. tenderness

COMPLICATIONS
-erosion of bowel wall/ perforation
-abscess
-peritonitis
-bleeding

17
Q

Diverticulitis Diagnostic studies

A

usual: sigmoidoscopy/ colonoscopy

Preferred: CT w/ oral contrast
- occult blood
- CBC, UA
- barium enema
- blood cultures
- abd. x-ray or chest x-ray: rule out other causes

18
Q

Goal of acute diverticulitis

A

bowel rest to reduce inflammation

  • clear liquids, bed rest, analgesia
  • if severe; hospitalization; NPO, NGT, bed rest, IV fluids w/ antibiotics.

surgical resection w/ anastamosis, or temporary colostomy if recurring

19
Q

Inflammatory Bowel Disease

A

chronic recurrent inflammation of GI tract.Common in teens and early adulthood. Peak in 60s

Ulcerative colitis
Chron’s disease

20
Q

IBD: etiology and pathophysi.

A

actual cause is unknown
Autoimmune disease: environmental or bacterial trigger causes an overactive, inappropriate, sustained immune response in a genetically susceptible person

200 genes associated

21
Q

IBD: environmental factors

A
  • diet, smoking, stress after microbial flora
  • high intake of refined sugar, fat, polyunsaturated fatty acid, omega-6 fatty acid
  • low intake of raw fruit, veggies, omega- 3 foods, dietary fibers

Drug associations: NSAIDs, antibiotics, oral contraceptives
