24
Q

what is INR

A

25
Q

normal INR

A

0.81 - 1.2

26
Q

what is the typical therapeutic INR lvl

A

2-3

<2 = med not effective at preventing blood clots
>3 = risk of bleeding
27
Q

what does the typical therapeutic INR lvl mean

A
  • it is considered the effective therapeutic range for people taking warfarin
28
Q

what is the difference betwen INR and PT (2)? similarities (2)?

A
  • INR is used more often
  • INR is calculated from PT time
  • both assess extrinsic and common pathways of the coagulation cascade
  • both used for pts taking warfarin
29

35
Q

what are the similarities between PTT and aPTT (1)? differences (2)

A

A

7.35 to 7.45

37
Q

what is pH

A
  • a scale used to measure the acidity or basicity of a solution
