Question 1:
I am a pale Irish woman and after I go for a run, my face is bright red – so much so that people often think something is wrong with me. I assure everyone that I am fine and because I know that this redness is due to

Red blood cells not functioning correctly
|
|
|
Platelets not functioning correctly
|
|
|
White blood cells not functioning correctly
|
|
|
Mast cells not functioning correctly
|
Question 6
Damage to the papillary muscles of the heart causes
|
|
A decrease in the function of the aorta
|
|
|
An inability of the heart valves to close
|
|
|
A decrease in respiration rate
|
|
|
An increase in blood pressure
|
Question 7
You have decided to come visit your professor in Colorado and you head up to the mountains to go for a hike. You notice that you quickly get tired and feel out of breath, but your professor seems just fine. This is likely because your professor
|
|
Has more red blood cells than you since she lives at a higher altitude
|
|
|
Has more white blood cells than you since she lives at a higher altitude
|
|
|
Is older than you and therefore breathes better at a higher altitude
|
|
|
Has fewer platelets than you since she lives at a higher altitude
|
Question 8
A patient has a heart murmur with a distinct "swishing" sound during the cardiac cycle. What causes this sound?
|
|
The filling of the ventricles with blood
|
|
|
The closing of the semilunar valves
|
|
|
The closing of the atrioventricular valves
|
|
|
The blood flowing back through a leaky valve
|
Question 9
In the image below, which of these is a capillary?
|
|
A
|
|
|
B
|
|
|
C
|
|
|
None of these
|
Question 10
The guards at Buckingham Palace in England must stand at attention for long periods of time without moving. The uniforms of these guards have pants with very wide legs. How are these two facts related?
|
|
The guards need the wide legged pants because it is the preferred style of the Queen who has commanded them to stand in front of her palace
|
|
|
The guards need the wide legged pants to protect them from the sun as they stand for long periods of time
|
|
|
The guards need the wide legged pants so that they can contract their calf muscles to help aid arterial blood flow and keep them from passing out
|
|
|
The guards need the wide legged pants so that they can contract their calf muscles to help aid venous return and keep them from passing out
|
|
|
There is no relationship between these two facts!
|
Question 11
How can damage to the left side of the heart also result in kidney damage?
|
|
The heart damage causes an increase in blood pressure which puts too much stress on the kidneys
|
|
|
The heart damage causes a decrease in blood pressure which prevents the kidneys from functioning
|
|
|
The heat damage causes a significant increase in cardiac output which puts too much stress on the kidneys
|
|
|
Both A and C
|
Question 12
You have a patient with left side heart damage. What should you expect to happen next?
|
|
Wet breath sounds and difficulty breathing
|
|
|
Numbness in the extremities
|
|
|
Increased cardiac output
|
|
|
Loss of memory
|

|
|

|
|
|

|
|
|
