NUR 325 ( LATEST 2024 / 2025 ) PERFUSION | (ACTUAL EXAM ) QUESTIONS AND ANSWERS (SOLVED)

NUR 325 Perfusion

1. Define Perfusion
Answer
the flow of blood through arteries and capillaries delivering nutrients and oxygen to cells

2. Define Ischemia
Answer
Lack of perfusion to the tissue


3. Define Infarction
Answer
Tissue death from sustained ischemia

4. Define Anoxia
Answer
lack of oxygen to tissue

5. What two factors are required for optimal perfusion?

Answer
-Working heart to pump blood

-Patent (unobstructed) vasculature
6. Central perfusion is the force of blood movement generated by

?

Answer
Cardiac output

7. What is the formula for Cardiac Output?

Answer

,Cardiac output = Stroke volume X Heart rate

8. Define Stroke volume
Answer
volume of blood ejected from the LV per beat

9. Central perfusion requires what 3 things?
Answer
1. Cardiac function

2. Blood pressure
3. Blood volume

10. Tissue/Local perfusion if the volume of blood that flows to where?
Answer
the target tissue

11. Tissue/Local perfusion requires what 3 things?
Answer
1. Patent blood vessels

2. Hydrostatic pressure
3. Capillary permeability

12. What is the cause of impaired central perfusion?
Answer
Inadequate cardiac output

13. Reduced cardiac output leads to what?
Answer
Less oxygenated blood getting to tissues so there is a SYSTEMIC EFFECT.

Ischemia Cell injury

, Infarction (cell death)

14. What is the cause of impaired tissue/local perfusion?
Answer
Inadequate




-Vessel patency
-Vessel permeability
-Central perfusion

15. Impaired tissue perfusion leads to ?
Answer
reduced blood flow to the affected body tissue so there is a LOCALIZED EFFECT.

Ischemia Cell injury
Infarction (cell death)


16. Perfusion can occur to all individuals, but which populations are at the greatest risk?
Answer
MMA

-Middle aged and older adults
-Men
-African Americans

17. risk factors for impaired perfusion
