Flashcards in Screening 6 Deck (29):
1

What are the coagulation disorders we discussed?

- hemophilia
- disseminated intravascular coagulation (DIC)

2

hemophilia is a bleeding disorder cause by a deficiency in

one of two blood clotting factors (proteins)
- factor VIII
- factor IX

3

What is the root cause of hemophilia?

several different gene abnormalities can cause the disorder

4

What is the main problem for people with hemophilia?

- people bleed unexpectedly or after minor injuries
- bleed longer, but not faster than normals

5

What is the most common clinical manifestation of s/s for hemophiliacs?

acute hemarthroses

6

What is the 2nd most common location of bleeds for hemophiliacs?

muscle bleeds

7

Where are muscle bleeds often seen?

flexor groups

8

With muscle bleeds, which are very important to distinguish between?

- iliopsoas bleed
- hip bleed

9

trunk flexion: iliopsoas bleed

causes severe pain

10

trunk flexion: hip bleed

causes mild pain

11

hip rotation: iliopsoas bleed

causes mild pain

12

hip rotation: hip bleed

causes severe pain

13

For hemophiliacs, what will repeated muscle bleeds cause over time?

- fibrotic tissue
- contractures
- possibility of peripheral nerve lesions from compression

14

Treatments for hemophilia

transfusions given to replace missing clotting factors

15

Hemophilia tx: transfusions will have greater concentrations of:

The factor they're deficient in

16

Hemophilia: Why must you watch for an acute hemarthrosis?

Pseudotumor or bone erosion can occur

17

What are the two forms of hemophilia?

- Hemophilia A
- Hemophilia B

18

Which is the most common form of hemophilia?

- Hemophilia A
- accounts for 80% of all cases

19

Hemophilia A is a deficiency of

clotting factor VIII

20

Hemophilia B is a deficiency of

clotting factor IX

21

Bleeding patterns and overall consequences: hemophilia A/B

both have similar bleeding patterns and overall consequences

22

DIC =

disseminated intravascular coagulation

23

What is DIC?

overactivation of clotting cascade with simultaneous and paradoxical

- clotting
- hemorrhaging

24

With DIC, get widespread deposition of ____. Where does this happen?

- fibrin
- in circulation and in major organs

25

Disseminated intravascular coagulation (DIC) is common after:

- shock
- sepsis
- OB/GYN complications
- cancer
- trauma

26

What should you always take into account with a pt who has DIC?

- NO PT during bleeding episodes
- monitor lab values carefully to see when it's safe to mobilize

27

Blood disorders overall: Guidelines for immediate medical attention

- Excessive or spontaneous bleeding
- Severe bruising previously seen or unreported

28

Blood disorders overall: Guidelines for physician referral

- May be warranted with exercise prescription for client with known anemia
- New episodes of joint or muscle pain in client with hemophilia

29

Blood disorders overall: Clues when screening for hematologic disease

- previous hx of chemo/radiotherapy
- chronic NSAID use
- spontaneous bleeding of any kind
- recent major surgery
- rapid onset of dyspnea
- chest pain
- weakness
- fatigue with palpitations associated with recent change in altitude
- observed changes in hands and nail beds
