Q

According to the Frank-Starling law of the heart:

a. Increase in venous return increases the end-diastolic volume, which leads to increased stroke volume
b. When venous return decreases, stroke volume increases to compensate
c. The cardiac output cannot be varied, thereby maintaining circulatory stability
d. Parasympathetic nerve activity decreases end-diastolic volume

A

Increase in venous return increases the end-diastolic volume, which leads to increased stroke volume

20
Q

an acute loss of blood is what type of anemia?

A

hemorrhagic anemia

21
Q

The rupturing of an excessive number of circulating erythrocytes is what type of anemia?

A

hemolytic anemia

22
Q

This condition is commonly known as a heart attack

A

Myocardial infarction

23
Q

What happens in the last step of blood coagulation

A

Fibrinogen is converted to fibrin

24
Q

a swishy murmur heard between the second and first heart sounds would be indicative of:

A

An insufficient (leaky) AV valve

25
Q

Since fibrinogen is always present in the blood but the blood does not clot, ________ must normally be absent

A

thrombin

26
Q

Which of the following would NOT increase blood pressure?

a. Increased blood volume
b. Increased sympathetic stimulation
c. Increased heart rate
d. Increased stroke volume
e. Decreased cardiac output

A

Decreased cardiac output

27
Q

The second heart sound

a. Occurs when the AV valve closes
b. Signals the onset of ventricular relaxation
c. Signals the onset of atrial contraction
d. Is produced by blood rushing through the AV valve during diastole creating a turbulent flow

A

Signals the onset of ventricular relaxation

28
Q

The second heart sound represents which of the below events?

a. Valvular stenosis
b. Semilunar valves opening
c. Atroventricular valves closing
d. Semilunar valves closing
e. Atrioventricular valves opening

A

Semilunar valves closing

29
Q

e. Increased sympathetic stimulation

A

Increased potassium levels

30
Q

Most of the carbon dioxide transported in the blood is transported as:

A

Thrombopoietin

32
Q

The common endpoint of Stage 2 (common pathway) of both the intrinsic and extrinsic pathways of hemostasis is the:

A

Production (formation) of thrombin

33
Q

When platelets come in contact with this substance in an injured vessel wall, it causes them to adhere and aggregate.

A

collagen

34
Q

Substance released by platelets that cause more platelets to adhere

A

35
Q

A plasma protein activated by Factor X complex

A

36
Q

Third step in hemostasis

A

Blood coagulation

37
Q

Released from injured tissue; activates extrinsic clotting pathway

A

thromboplastin

38
Q

This agent is involved in the vascular spasm phase/stage of hemostasis

A

Thromboxane A2

39
Q

If the end-diastolic volume were held constant, increased stroke volume could be accomplished by:

A

Increased sympathetic nerve activity to the heart
