Patho

 

  • ⇑ WBC
  • ⇑ RBC
  • ⇑ Platelets
  • Clients are prone to clots and do not live very long. Die from a myocardial infarct or a stroke.

Causes

  • Cause: cancer usually in older adults 50- 75 y/o
  • Too many RBCs leading to increased hematocrit, hypervolemia, hyperviscosity, and hypertension
  • Clients with COPD who have chronic hypoxia may start making for RBCs to compensate.

Symptoms

  • Red face due to excess RBCs
  • Purple or cyanotic skin and mucuous membranes due to hypoxic blood
  • Severe burning/itching due to thick, poorly oxygentated blood.
  • Hypertension (remember blood is thick)
  • Dilated vessels
  • Clots due to obstructed blood flow.
  • Infarcts of organs (heart, brain)
  • Visual disturbances, headache, orthopnea, gout!
  • gout: painful swollen joints (usually big toe)
  • Orthopnea is due to heart failure
  • dizziness, feelilng of fullness in the head, Tinnitus
  • Think hypertension s/s
  • Uric acid and potassium increase (gout, renal failure, hyperkalemia)

Nursing Interventions

  • Apheresis/phlebotomy: removal of RBCs to reduce viscosity.
  • Hydration to reduce viscosity
  • No iron supplements
  • Anticoagulations (makes sense since at risk for clots)
