Q

What position should the arm be when taking blood pressure?

at heart level and supported

17
Q

the sounds of Korotkoff are turbulent sounds made by blood passing through ________________________

A

constricted arteries

18
Q

What is the formula to calculate blood pressure?

A

Cardiac output x peripheral resistance

19
Q

The amount of blood pumped in 1 minute

A

cardiac output

20
Q

Cardiac output is the amount of blood pumped in ____________________

A

1 minute

21
Q

________________ blood pressures is estimated rather than measured

A

venous

22
Q

________________ can indicate vascular problems

A

skin color

23
Q

Reclining 2-3 min (decreases/increases) BP and (decreases/increases) heart Rate…. why?

A

decreases, decreases, due to low gravity

24
Q

Immediately standing after resting (decreases/increases) BP and (decreases/increases) heart Rate…. why?

A

decreases, increases, CO decreases because venous return decreases for a second

25
Q

Exercising (decreases/increases) BP and (decreases/increases) heart Rate…. why?

A

increases, increases, because cardiac output increases

26
Q

Submersion in cold water (decreases/increases) BP and (decreases/increases) heart Rate…. why?

A

increases, increases, because the blood vessels constrict

27
Q

What are 4 factors that affect CO and PR?

A
  1. vasoconstriction/vasodilation
  2. condition of blood vessels
  3. viscosity of blood
    4 additional forces (gravity)
28
Q

What are the 3 factors that affecting peripheral resistance?

A
  1. arteriole diameter
  2. vessel length
  3. blood viscosity
29
Q

What are the 5 factors that affecting cardiac output?

A
  1. blood volume
  2. vein diameter
  3. venous return
  4. stroke volume
  5. heart rate
30
Q

What artery is most commonly used to discern pulse?

A

radial artery
