NEW Q&A 100% Correct
What is blood pressure?:
The force exerted on artery walls during contraction
Cardiac contraction (pressure during contraction):
Systole
Cardiac relaxation (pressure during relaxation):
diastole
What is the normal ranges for blood pressure in an adult?:
- Systolic: 100-120
- Diastolic: 60-80
T/F Typically most attention is given to the systolic number in a clinical setting: True; Systolic number indicates how much force is being exerted. If your systolic number is low, you aren't able to push your blood through your body effectively.

Hypotension:
Low blood pressure
Hypertension:
High blood pressure (HTN)
What are Karotkoff sounds?: The 5 sounds you hear when tak ing a blood
pressure
Which two Karotkoff sounds do we care about?:
First sound = Systolic Last sound (absence of sound) - Diastolic
Adequate blood pressure necessary for tissue/organ perfusion:
Mean arterial pressure (MAP)
How do you calculate MAP?:
(SBP + 2DBP)/3 Example:
120/80
(120 + 2*80)/3 = 93.3
- / 3
What is the minimum MAP that is necessary to perfuse tissues/organs?-
: 60 or greater
T/F When a patient first arrives you should asses their blood pressure on one
side only?:
F; You will take their blood pressure bilaterally to get the most accurate reading then use the site with the highest initial BP
What site is the first choice for taking BP?:
Upper arm
In order, what alternative sites can you take BP?:
Forearm, thigh, calf (BP may be 20-30 mm Hg higher in lower extremities)
List reasons why you couldn't take blood pressure at a specific site?:
- Upper arm IV, mastectomy/lymph node removal, dialysis fistula, trauma,
wounds, dressings, cast
T/F It is ok to take BP on an upper arm if the clients IV is in there hand:
T; as long as we are not putting the BP cuff over the IV it is ok. However, we want to try and avoid that arm if able.
