Flashcards in Screening 2 Deck (26):
1

What are the 3 types of erythrocytes disorders we talked about (broad)?

- anemia
- polycythemia
- sickle cell anemia

2

What type of disorder is anemia?

- NOT a disease
- sx of different blood disorders

3

Anemia is a reduction in

Oxygen-carrying capacity of blood

4

What does reduction in oxygen-carrying capacity of blood come from?

Abnormality in quantity or quality of erythrocytes

5

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

6

What chronic diseases do we often see too few erythrocytes in?

- cancer
- kidney
- liver

7

Which inflammatory diseases do we see too few erythrocytes in?

- RA
- SLE

8

What neuro dz do we see too few erythrocytes in?

Pernicious anemia

9

What infectious dz do we see too few erythrocytes in?

- TB
- AIDS

10

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)

11

With anemia, dyspnea with exertion will be accompanied with this in more severe cases

Heart palpitations

12

Skin changes often seen with anemia

- pallor
- jaundice

13

Anemia: highly variable sx depending on

Rate of developing anemia

14

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

15

Anemia: If hands are not warm, what is paleness likely due to?

Vasoconstriction

16

Anemia: pallor assessed in dark-skinned pts

Seen via absence of underlying red tones

17

Assessing for anemia: exercise tolerance

Diminished

18

Anemia will decrease exercise tolerance and may impair _________

Oxygenation

19

Exercise and anemia: older adults should be monitored for:

- circulation issues
- changes in cognitive function with exercise

20

Older adults and anemia: sedentary lifestyle may actually be a result of

Self-imposed changes to accommodate diminished oxygenation or anemia

21

As anemia becomes severe, may see an increase in cardiac output and decrease in exercise tolerance, resulting in:

- dyspnea
- tachycardia
- palpitations

22

Young females and anemia

- Young, female athletes at increased risk for anemia and iron deficiency
- may also have inadequate dietary intake

23

CRF

Chronic renal failure

24

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

25

Pts with anemia and cardiovascular disease at a higher risk for

Angina

26

Anemia impairs

Wound healing
