Lab exam #2 Flashcards
When the valves stiffen, this is called ____
stenosis
“Maximum amount of air that can be moved in the lungs in the largest breath”
Vital capacity
What is the average resting heart rate?
75bpm
If your blood type is O+, which antibody(s) is present?
αA and αB
If you have the antibody B floating in your plasma, what blood type are you? (ignore Rh factor)
A
“Amount of air that cannot be forced from the lungs”
Residual volume
What does E encompass?
E encompasses the IRV, TV, and ERV, which is Vital Capacity.
If your blood type is B+, which antibody(is) is present?
αA
What is the most common blood type?
(in the world: A +) (In USA: O-) (need to ask prof. which one he meant)
People that are hypo-reactive will….
Maintain a relatively stable Bp in cold…neither sys/dia will go above baseline by more than 22mmhg
Apical pulse pressure is taken…
Taken at the heart (count the number of Lub-dups)
In pregnancy, why does the αRh diffuse and not the αA or αB?
Because the Rh molecules are smaller
Name the two tools used to measure BP
Stethoscope and sphygmomanometer
How do you find pulse pressure?
Systolic minus diastole
___ = TV + IRV + ERV
VC (vital capacity)
Your blood type is determined by ______, but decided by_______
determined by antigens, but decided by genetics
What are the three primary predictors of vital capacity?
Height, age, and gender
blood antigens are a type of ______
glycoprotein
What is floating in your plasma, antigens or antibody’s?
Antibody’s
“Volume of air inhaled or exhaled at rest” this describes…..
Tidal volume
What is the average TV at?
.500L
Isovolumetric relaxation occurs when the ____ valves close
Sl
In the lab, what’s one way to determine blood type?
The technician will use antibodies on the patient’s blood to see what agglutinates.
If your blood type is AB-, list all the antigens and alphas
Antigen: A and B Antibody: αRh
The Lub sound you hear occurs when ____ valves close
AV
What does C indicate?
C indicates TV + IRV which equals the inspiratory capacity.
What does it mean to auscultate?
To hear and listen to the heart valves opening and closing

What does the residual volume prevent?
Prevents the lungs from collapsing
If your blood type is O-, which antibody(s) is present?
αA, αB, and αRh
If your blood type is B-, which antibody(s) is present?
αA and αRh
If your blood type is positive which Rh factor do you have?
The Rh antigen
“volume of air that can be forcibly inhaled beyond tidal volume”
Inspiratory reserve volume (IRV)
Why can O- people only receive blood from O-?
Because all other blood types have an antigen attached to their blood cells. O- has αA, αB, and αRh, which means any other blood type given would cause O- ‘s antibodies to attach and destroy the antigens it was just given. O- has no antigens, so the donor can only be another O-
What is the equation for finding MAP?
MAP = 2/3(DIA) + 1/3 (SIA)
How do you prevent hemolytic disease of newborns?
Mom receives an injection that binds to the antigens of the fetus so the mom’s antibodies cannot attach.
Atherosclerosis is the build up of _____ on the walls, leading to the stiffening of the arteries which is called ______
plaque; arteriosclerosis
A positive or negative blood type indicates the presence or absence of what on the red blood cell?
The Rh antigen
the suffix “itis” indicates _______
inflammation
Chronic high blood pressure can lead to ______
atherosclerosis
You listen at the ____ intercostal space to hear the AV valves
5th
What does pulse deficit indicate?
Indicates something is wrong with the heart or cardio system
When measuring bp, how do you find your systolic measurement?
After you occlude the artery, slowly start to deflate the cuff. When you hear the first korotkoff sound, look at the sphygmomanometer. The number with the first sound is your systolic.
Make sure measurements are with 3 decimal places…
(-:
What are the secondary factors that can predict VC?
Pulmonary diseases, fitness level, and the quality of the air
Remember to always write your ______ after the answer or he’ll mark it wrong
measurement (mmhg, bpm, etc.)
Assume that RV is _____L
1.00L
Calculate the MAP for 120/90
100mmhg
500mL = ___ L
.500L
