MONTANDON, AND DR. SCHOLEY) UPDATED
ACTUAL QUESTIONS AND CORRECT ANSWERS
Question:
1. Korotkoff sounds
Answer:
Series of sounds that correspond to changes in blood flow through an artery as pressure is released

Question:
2. 1. Snapping sound = systolic pressure
2. Murmurs = systolic to diastolic
3. Loud, crisp tapping sound
4. Thumping = ~10mmHg above diastolic
5. Silence = diastolic
Answer:
Five Korotkoff sounds

Question:
3. Pulse
Answer:
Pressure wave of circulating blood Monitored at pressure points

Question:
4. Temporal artery
Answer:
Artery palpated at the temple

Question:
5. Facial artery
Answer:
Artery palpated at the jaw/cheek

Question:
6. Carotid artery
Answer:
Artery palpated at the neck

Question:
7. Brachial artery
Answer:
Artery palpated at the inner elbow

Question:
8. Radial artery

,Answer:
Artery palpated at the wrist

Question:
9. Femoral artery
Answer:
Artery palpated at the groin

Question:
10. Popliteal artery
Answer:
Artery palpated behind the knee

Question:
11. Posterior tibial artery
Answer:
Artery palpated at the ankle

Question:
12. Dorsalis pedis artery
Answer:
Artery palpated at the top of the foot

Question:
13. Pulse pressure
Answer:
Systolic pressure - diastolic pressure

Question:
14. 40 mmHg
Answer:
Pulse pressure at 120/80 mmHg

Question:
15. Mean Arterial Pressure (MAP)
Answer:
diastolic pressure + 1/3 (systolic P diastolic P) OR 2/3 diastolic + 1/3 systolic OR Cardiac output x
resistance

Question:
16. 93.3 mmHg
Answer:
Mean arterial pressure at 120/80

Question:
17. Stroke volume
Answer:
What factor MOST affects pulse pressure?

,Question:
18. Diameter of the arterioles
Answer:
What determines resistance regarding blood flow?

Question:
19. Total flow (Cardiac output)
Answer:
(Pressure in arteries - pressure in veins)/Total peripheral resistance

Question:
20. VGCC
Answer:
voltage-gated calcium channels For our purposes: L-type calcium channels

Question:
21. Diameter of the veins
Answer:
How is the relative distribution of blood between arteries and veins determined?

Question:
22. Fluid intake and fluid loss (either passive or regulated by kidneys)
Answer:
How is blood volume regulated?

Question:
23. Renin angiotensin aldosterone system (RAAS)
Answer:
Decreased BP --> renin released from kidneys --> renin converts angiotensinogen to angiotensin I in
the liver --> ACE from the lung converts angiotensin I to angiotensin II, which acts on Gq receptors in
the adrenal cortex --> kidneys retain salt and water

Question:
24. Aldosterone
Answer:
Hormone that causes retention/reabsorption of salt (and thus water) by the kidney

Question:
25. Baroreceptors
Answer:
Monitor blood pressure Ex. aortic arch, carotid sinus, etc.

Question:
26. Compensation by cardiovascular system (vasodilation and decreased cardiac output)
Answer:
Fast response to high blood pressure

, Question:
27. Compensation by kidneys (excretion of fluid in urine, decreased blood volume)
Answer:
Slow response to high blood pressure

Question:
28. Hypertension
Answer:
Abnormally high blood pressure

Question:
29. Orthostatic hypotension
Answer:
Low blood pressure that occurs upon standing up

Question:
30. - Increased venous return
- Increased sympathetic activity
- Vasodilation in skeletal muscle
Answer:
Cardiovascular responses to exercise

Question:
31. Brain, kidneys, GI system, skin
Answer:
Organs that get more blood at rest

Question:
32. Heart (dramatically) and skeletal muscle (dramatically)
Answer:
Organs that get more blood during exercise

Question:
33. Theories about MAP in exercise
Answer:
1.) Sympathetic activity causes baroreceptors to think higher pressures are normal
2.) Baroreceptor transmission is blocked during exercise
3.) Chemoreceptor (low pH) signals outweigh baroreceptor signals

Question:
34. True capillaries
Answer:
Capillaries with continuous walls that participate in exchange Found in muscles and the brain

Question:
35. Fenestrated capillaries
