Deck 8: Cardiopulmonary and Cardiovascular Function

Question 1

Amyloidosis is:

A)An inability to metabolize amyloid factors via excretion
B)A histologic feature of aging characterized by the progressive deposition of amyloid protein in the vascular system
C)A deficit in amyloid protein in the vascular system leading to irregularities in electrical conduction
D)A faulty interaction between pulmonary and cardiovascular systems as a result of loss of amyloid

Answer 1

B

Question 2

Which is an accurate statement about function in later life as affected by pulmonary and cardiovascular function?

A)Functional capacity is often retained and may improve with age.
B)Function may be maintained even when capacity is lost.
C)Function typically declines regardless of the status of capacity.
D)Capacity and function are unrelated in almost every situation.

Answer 2

B

Question 3

Functional capacity refers to:

A)The capacity of the cardiovascular system to transport oxygen
B)Ability to complete activities of daily living
C)Endurance during moderate exercise
D)Balance of activities during the course of a given day

Answer 3

A

Question 4

The functional performance threshold can be thought of as the:

A)Level of social and environmental support required to undertake daily activity
B)Function required to accomplish specific work-related tasks with adequate endurance
C)Ability to perform activities of daily living to meet the minimum criterion compatible with personal care and independent living
D)Performance desired by the individual to ensure best quality of life

Question 5

The metabolic demands of activities,in general:

A)Change significantly throughout the life span
B)Change from childhood to young adulthood,then remain constant
C)Change in later life as capacity diminishes
D)Remain constant throughout the life span

Question 6

The generally recommended goal for intervention relative to pulmonary and cardiovascular function is to:

A)Maintain physiological capacity and reserve well above the functional performance threshold
B)Increase capacity and reserve to the greatest extent possible through vigorous physical activity intervention
C)Maintain function without regard to pulmonary and cardiovascular capacity
D)Accept inevitable significant decrease in pulmonary and cardiovascular capacity and focus on adaptive strategies

Question 7

Which of the following defines a sedentary lifestyle?

A)Biking 20 or fewer miles per day
B)Walking 10,000 steps
C)Walking fewer than 5,000 steps
D)Thirty minutes per day of computer time

Question 8

Which of the following is an age-related change in the chest wall?

A)The joints of the thorax become more rigid,and cartilage becomes calcified.
B)The diaphragm becomes more flexible,resulting in less force during inhalation.
C)Arterial oxygen tension and saturation decrease.
D)Recumbent position increasingly improves pulmonary capacity by expanding chest wall.

Question 9

Age-related changes in heart valves result in:

A)Increased blood flow through the heart and into the lungs
B)Improved oxygenation of venous blood
C)Decreased respiration
D)Less efficient pumping of blood through the heart

Question 10

Change in body position can be associated with all of the following EXCEPT:

A)Postural hypotension
B)Dizziness or fainting
C)Increased blood flow to the brain
D)Slowed autonomic response
