Week 5 Flashcards
What aspect of primary aging leads to impaired blood flow?
The thickening of the valve leaflets
What aspect of primary aging leads to Decreased HR in response to exercise?
A decreased response to catecholamines
What two aspects of primary aging leads to Decreased Contractile force?
Thickened left ventricle and stiffened pericardium
What is secondary to decreased contractile force?
Decreased Cardiac output
What aspect of primary aging leads to dysrhythmias?
Decreased number of pacemaker cells
What aspect of primary aging leads to an increased risk for atherosclerosis
Arteries become stiff and tortuous
What aspect of primary aging leads to increased orthostatic changes?
Blunted baroreceptor response
What aspect of primary aging leads to a risk for varicosities
Dilation of veins
What aspect of primary aging leads to a risk for peripheral edema and decreased blood return?
Incompetent valves
What side of the body is more prone to peripheral edema?
The right side
What aspect of primary aging leads to decreased lung expansion?
Calcification of ribs and Vertebral joints
What aspect of primary aging leads to thicker mucus?
Body water is reduced by 50% at age 70
What aspects of primary aging leads to Decreased respiratory effort?
- Elastin and collagen loose tensile strength
- Respiratory muscle atrophy and fatigue
What aspect of primary aging leads to increased obstruction of nasal passages?
Change in nasal structure
What aspect of primary aging leads to an ineffective mucus escalator?
A decrease in cillia
What aspect of primary aging leads to a decreased response to hypoxia/hypercapnia?
Decreased tidal volume
What aspect of primary aging leads to prolonged expiratory time?
Residual volume increases
What aspects of primary aging leads to less area for gas exchange?
- the alveoli become less elastic
- and there are fewer functional capillaries
What aspect of primary aging leads to the need to use accessory muscles while at the same time lung capacity stays the same?
Inspiration becomes less powerful and expiration is no longer passive
What are some nursing managements to help reduce cardiac workload
Space activities
encourage regular light physical activity
What are some nursing managements to improve/maintain function
loose weight
What aspect of primary aging leads to Difficulty swallowing and speaking?
Lose or fracture of teeth
What aspect of primary aging leads to dry mouth and altered digestion
Decreased salivary gland production
What aspect of primary aging leads to possible Changes in appetite
Decreased number of taste buds
