1Pulse pressure is the difference between [blank_start]systolic[blank_end] and [blank_start]diastolic[blank_end] pressure.
- Asystolic
- Bdiastolic
2If your systolic blood pressure is 120 and your diastolic pressure is 67, what is the pulse pressure?
- A45
- B50
- C53
- D55
3If your systolic blood pressure is 110 and your diastolic is 80, what is your mean arterial pressure?
- A85
- B90
- C65
- D75
4[blank_start]Vascular distensibility[blank_end] is the ability of a vessel to stretch.
- AVascular distensibility
5[blank_start]Veins[blank_end] are the most distensible vessels. They are [blank_start]8[blank_end] (numeral) times more distensible than arteries.
- AArteries
- BVeins
- C4
- D5
- E8
- F10
6Vascular distensibility equals [blank_start]vascular tone[blank_end].
- Avascular tone
7[blank_start]Vascular compliance[blank_end] is the total quantity of blood that can be stored in a given portion of the circulation for each mmHg of pressure. It's the ability of a vessel to stretch and hold volume.
- AVascular compliance
8[blank_start]Compliance[blank_end] is the ability of a vessel to stretch and hold volume.
- ACompliance
9The two factors affecting pulse pressure are [blank_start]arterial compliance[blank_end] and [blank_start]stroke volume[blank_end].
- Aarterial compliance
- Bstroke volume
10If all other factors are equal, the pulse pressure reflects the [blank_start]stroke volume[blank_end].
- Astroke volume
11Factors Affecting Pulse Pressure:
Increase in stroke volume [blank_start]increases[blank_end] pulse pressure. Conversely, decreases in stroke volume [blank_start]decrease[blank_end] pulse pressure.
Decreases in arterial compliance [blank_start]increase[blank_end] pulse pressure. Increases in compliance [blank_start]decrease[blank_end] pulse pressure.- Adecreases
- Bincreases
- Cdecrease
- Dincrease
- Edecrease
- Fincrease
- Gdecrease
- Hincrease
12Which of the following describes how arteriosclerosis affects pulse pressure?
- APulse pressure is increased to nearly twice normal
- BPulse pressure is significantly decreased
- CDiastolic pressure falls very low before the next heartbeat
- DAortic pressure can fall all the way to zero between heartbeats.
13Match the following abnormal pressure pulse contours to their definitions:
[blank_start]Arteriosclerosis:[blank_end] Decreases compliance of arterial tree, thus leading to increase in pulse pressure.
[blank_start]Patent Ductus Arteriosus:[blank_end] Associated with low diastolic pressure and high systolic pressure, net result is very high pressure.
[blank_start]Aortic regurgitation:[blank_end] Condition associated with backward flow of blood through the aortic valve. Low diastolic and high systolic pressure leads to high pulse pressure.- AArteriosclerosis:
- BPatent Ductus Arteriosus:
- CAortic regurgitation:
14What number represents a widened pulse pressure?
- AGreater than 30
- BGreater than 40
- CGreater than 50
- DGreater than 60
15What number represents a narrowed pulse pressure?
- ALess than 10 mmHg
- BLess than 20 mmHg
- CLess than 30 mmHg
- DLess than 40 mmHg
16[blank_start]60[blank_end] (number) percent of the blood is in the veins.
- A60
17When veins are constricted, large quantities of blood are transferred to the heart, thereby increasing [blank_start]cardiac output[blank_end].
- Acardiac output
18The Law of LaPlace reminds us that as a structure [blank_start]expands[blank_end], it increases it radius.
- Aconstricts
- Bexpands
19Select the relationship between the Law of LaPlace, wall tension and radius.
Increased vessel, [blank_start]increased[blank_end] radius, and [blank_start]increased[blank_end] tension- Adecreased
- Bincreased
- Cdecreased
- Dincreased
