Bl Week 2 Pbl Objective 3

Front 1

What does the presence of petechiae suggest?

Back 1

Platelet-type bleeding.

Front 2

What are petechiae?

Back 2

Minute (1-2 mm) hemorrhages into skin, mucous membranes or serosal surfaces.

Front 3

Name 2 classic indicators of platelet-type bleeding.

Back 3

1. petechiae
2. mucosal surface bleeding (i.e. gum bleeding, menorrhagia)

Front 4

What does platelet type bleeding mean?

Back 4

Physical findings specifically suggest a platelet problem as the cause for the patient's bleeding.

Front 5

What does purpura give information about?

Back 5

May indicate non-hematologic defects (i.e. vasculitis)

Front 6

What is purpura?

Back 6

3-5 mm hemorrhage that can be associated with platelet or clotting factor deficiencies.
Can also occur with trauma, vasculitis, or increased vascular fragility.

Front 7

What is ecchymosis?

Back 7

Large (1-2 cm) subcutaneous hemotoma (bruise)

Front 8

What is factor-type bleeding?

Back 8

Physical findings suggest a factor abnormality (factor deficiency or presence of an inhibitor) as the cause for the patient's bleeding. Suggested by hemarthroses and deep tissue hematomas.

Front 9

Define hemorrhage.

Back 9

Extravasation of blood from vessels into the extravascular space.

Front 10

What is a hematoma?

Back 10

Any accumulation of blood that is external or confined within a tissue.
Can be insignificant (bruise) to fatal (massive retroperitoneal hematoma resulting from rupture of a dissecting aortic aneurysm).

Front 11

Which bleeding manifestation is considered the largest?

Back 11

Ecchymosis.
