Flashcards in Screening 2 Deck (26):
What are the 3 types of erythrocytes disorders we talked about (broad)?
- sickle cell anemia
What type of disorder is anemia?
- NOT a disease
- sx of different blood disorders
Anemia is a reduction in
Oxygen-carrying capacity of blood
What does reduction in oxygen-carrying capacity of blood come from?
Abnormality in quantity or quality of erythrocytes
Where do we often see too few erythrocytes?
- iron deficiency, chronic GI blood loss due to NSAIDs
- chronic diseases
- inflammatory diseases
- neuro diseases
- infectious diseases
- neoplasticism diseases
What chronic diseases do we often see too few erythrocytes in?
Which inflammatory diseases do we see too few erythrocytes in?
What neuro dz do we see too few erythrocytes in?
What infectious dz do we see too few erythrocytes in?
What types of s/s will be seen with anemia?
- skin changes
- fatigue and listlessness
- dyspnea on exertion
- chest pain with minimal exertion
- decreased diastolic BP
- CNS manifestations (pernicious anemia)
With anemia, dyspnea with exertion will be accompanied with this in more severe cases
Skin changes often seen with anemia
Anemia: highly variable sx depending on
Rate of developing anemia
Anemia: look for this with skin and fingernails
- look for pale palms with normal colored creases
- observe hands at level of client's heart
- hands should be warm
Anemia: If hands are not warm, what is paleness likely due to?
Anemia: pallor assessed in dark-skinned pts
Seen via absence of underlying red tones
Assessing for anemia: exercise tolerance
Anemia will decrease exercise tolerance and may impair _________
Exercise and anemia: older adults should be monitored for:
- circulation issues
- changes in cognitive function with exercise
Older adults and anemia: sedentary lifestyle may actually be a result of
Self-imposed changes to accommodate diminished oxygenation or anemia
As anemia becomes severe, may see an increase in cardiac output and decrease in exercise tolerance, resulting in:
Young females and anemia
- Young, female athletes at increased risk for anemia and iron deficiency
- may also have inadequate dietary intake
Chronic renal failure
What precautions should be taken with pts who have chronic renal failure?
- should exercise at lower intensities
- VO2 max is about 20% lower than normal
Pts with anemia and cardiovascular disease at a higher risk for
