1. To be accurate in measuring blood pressure, a person should not drink coffee and smoke cigarette for at least 24 hours from the time of measurement. (True/ False)
2. The term blood pressure usually refers to the pressure in the arteries, veins, and capillaries. (True/ False)
3. The Angiotensin-1 is a substance normally present in the:
a. Blood
b. liver
c. Kidney
d. Bone marrow
4. Systolic blood pressure of less than 135 mmHg and diastolic blood pressure of less than 95 mmHg is called hypotension. (True/ False)
5. Systolic blood pressure of the vein equal to 70 mmHg. (True/ False)
6. During exercise, for example, a greater percentage of the total blood flow is diverted to skeletal muscles leading to a sudden drop in blood pressure. (True/ False)
7. One hormone regulates blood pressure:
a. Prolactin
b. Vasopressin
c. Aldosterone
d. Corticosteroid
8. In measuring diastolic blood pressure, heart sound must be heard by the stethoscope when the sphygmomanometer recording normal blood pressure of 80 mmHg. (True/ False)
9. High blood cholesterol interferes with the elasticity of the arteries resulting in increased blood pressure. (True/ False)
10. Hormones regulate blood pressure by the alternation of:
a. Body temperature
b. Cardiac output
c. Venous blood retention
d. Pulse rate
11. To get the best results in measuring blood pressure, the arm must be resting on a table so that it is about the same level as the heart. (True/ False)
12. Typically blood pressure is usually measured in the brachial artery in the left arm by using sphygmomanometer and stethoscope. (True/ False)
13. Renin as hormone secrets by:
a. Kidney
b. Liver
c. Bone marrow
d. Spleen
14. Both blood pressure and pulse rate are related to heart pumping blood in the arterial blood vessels. (True/ False)
1) it should be false
Tobacco has nicotine which shows it's effect within 30 minutes and it's t1/2 is 2 hours and it is active for approximately 20 hours, so smoking should be avoided atleast half an hour before blood pressure measurement.
Similarly caffeine has t1/2 of 4 hours, and it's duration of action is also 4 hours, so it should be eliminated 1 hour before blood pressure measurement as it has onset of action as 1 hour.
2) True
Blood pressure is defined as pressure exerted against the wall of blood vessels by blood.
Blood pressure is the product of cardiac output and peripheral resistance.
It can be measured in arteries, veins and capillaries.
Blood pressure is lowest in veins and highest in arteries.
3) answer should be a) blood
Angiotensinogen is produced in the liver but angiotensim-1 is produced from angiotensinogen by the action of enzyme renin. Renin is produced by kidney.
Angiotensin-1 is converted to angiotensin-2 by the action of an enzyme angiotensin converting enzyme in the blood..
4) False.
Normal blood pressure is termed when systolic blood pressure is less than 120mmHg and diastolic blood pressure is less than 80 mmHg.
Hypertension is termed when systolic blood pressure is more than 129 mmHg and diastolic blood pressure is 90 mmHg.
Hypotension is termed when systolic blood pressure is less than 90 mmHg and diastolic blood pressure is less than 60 mmHg.
