Chapter 48 Pulse Rate and Blood Pressure
1) The difference between the maximum arterial pressure and the minimum arterial pressure is called the
A) diastolic pressure.
B) pulse pressure.
C) cardiac pressure.
D) systolic pressure.
E) mean arterial pressure.
2) After blood flows through the capillaries, the blood pressure derived from the heart is insufficient to return blood to the heart through the veins.
3) In order to be palpated to obtain the pulse, an artery must be
A) at least 1/2 inch in diameter.
B) close to the heart.
C) above the knee.
D) superficial and above the knee.
E) superficial, with firm tissue beneath it.
4) Which of the following is not true of the respiratory pump?
A) It is a mechanism that helps with venous return to the heart.
B) Contraction of the diaphragm causes an increase in the volume of the thoracic cavity, and a decrease in pressure.
C) Increased venous return to the heart causes the heart rate to increase.
D) More blood enters the heart during expiration than inspiration.
E) All of these are true of the respiratory pump.
5) When the left ventricle is at the end of its filling cycle, the ________ pressure is reached.
A) pulse
B) diastolic
C) cardiac
D) systolic
E) mean arterial
6) Blood pressure is expressed as
A) systolic pressure / diastolic pressure.
B) diastolic pressure / pulse pressure.
C) pulse pressure / systolic pressure.
D) diastolic pressure / systolic pressure.
E) systolic pressure / pulse pressure.
7) The thumb should not be used to take the radial pulse, because a person may feel a pulse from an artery in the thumb instead.
8) What is the cardiac output in a person with a heart rate of 65 beats/min and a stroke volume of 72 ml/beat?
A) 4,680 mL/beat
B) 137 mL/min
C) 4,680 mL/min
D) 1.1 mL/beat
E) 4,680 beats/min
9) Blood pressure would decrease if either the heart rate or stroke volume decreased.
10) Which of the following is not true of the effects of various factors on blood pressure?
A) An increase in cardiac output increases blood pressure.
B) An increase in peripheral resistance decreases blood pressure.
C) An increase in blood volume increases blood pressure.
D) An increase in vasoconstriction of blood vessels increases blood pressure.
E) All of these are true of the effects of various factors on the blood pressure.
11) As blood flows away from the heart through the systemic circuit, what is the first type of blood vessel in which the systolic and diastolic pressures can no longer be detected?
A) Capillaries
B) Large veins
C) Arterioles
D) Venules
E) Small arteries
12) What is the most significant factor in determining the peripheral resistance in a blood vessel?
A) Hematocrit
B) Blood vessel diameter
C) Blood viscosity
D) Blood vessel length
E) All of these factors contribute equally to the peripheral resistance in a blood vessel.
13) When measuring blood pressure with a sphygmomanometer, the pressure at which the first loud tapping sound is heard is recorded as the ________ pressure.
A) systolic
B) mean arterial
C) coronary
D) diastolic
E) pulse
14) When a person who is lying down suddenly stands up, the pulse rate decreases, due to the effects of gravity.
15) When a person suddenly moves from a supine position to a standing position, the blood pressure increases.
