Question | Answer |
---|---|
What is the purpose of breathing (name two) | (1) - to provide oxygen for tissue perfusion so that cells have enough oxygen to metabolize and generate energy 2) - to remove carbon dioxide, the waste product of metabolism |

Name the accessory muscles that help during breathing | |
What do the scalene muscles do | |
What does the sternocleidomastoid muscles do | |
What do the trapezius and pectoralis muscles do | |
What changes in the alveoli are related to aging | Surface area decreases, diffusion capacity decreases,elastic recoil decreases, bronchioles and alveolar ducts dilate, ability to cough decreases, airways close early |
What nursing interventions should you use because of the changes in the alveoli | |
Why are interventions needed for the change in alveoli | Potential for mechanical or infectious respiratory complications is increased in these situations.The upright position minimizes ventilation perfusion mismatching |
What physiologic changes occur in the lungs that are related to aging | Residual volume increases,vital capacity decreases, efficiency of oxygen and carbon dioxide exchange decreases, elasticity decreases |
What interventions would you use because of the changes in lungs due to aging | Include inspection, palpation, percussion and auscultation in lung assessments,help patient actively maintain health and fitness, assess patients respirations for abnormal breathing patterns, encourage frequent oral hygiene |
What are the rationales for using these interventions for the changes in lungs due to aging | The focused lung assessments are needed to detect normal age-related changes,health and fitness keep losses of respiratory functioning to a minimum, periodic breathing patterns (e.g. Cheyne Stokes) can occur, oral hygiene aids in the removal of secretions |
What are the physiologic changes in the pharynx and the larynx that are related to aging | Muscles atrophy,vocal cords becomes slack, laryngeal muscles lose elasticity airways lose Cartilage |
What intervention would you use because of changes in the pharynx and larynx r/t aging and what is the rationale | |

What interventions should you use due to the pulmonary vascular to change r/t aging and why | |
What kind of physiologic change occurs to the elderly's exercise tolerance, What intervention should you use and why | Body's response to hypoxia and hypercarbia decreases, assess for subtle manifestations of hypoxia because early assessment helps prevent complications |
What physiologic changes do you notice in the elderly's muscle strength | Respiratory muscle strength, especially the diaphragm and the intercostals decrease, |
What interventions can you use r/t changes in elderly and what are the rationales | Encourage pulmonary hygiene and help patient actively maintain health and fitness, Because regular hygiene and overall fitness help maintain maximal functioning of the respiratory system and prevent illness |
what intervention could you use to prevent infection and why | Encourage pulmonary hygiene and help patient actively maintain health and fitness, Because regular hygiene and overall fitness help maintain maximal functioning of the respiratory system and prevent illness |
What changes occur to the elderly's chest wall | Anteroposterior diameter increases, thorax becomes shorter, progressive kyphoscoliosis occurs chest wall compliance (elasticity) decreases, mobility may decrease, osteoporosis is possible |
Discuss the normal changes of aging - patients may be anxious because they must work harder to breathe, Discuss the need for increased rest periods during exercise | |
Women have greater bronchial responsiveness and larger airways, this factor increases the risk for a more rapid decline in lung function as the woman ages | |
Patients with dark skin usually show a lower oxygen saturation because of the deeper coloration of the nail bed and this does not reflect the true oxygenation | |
Why are the elderly more susceptible to infection, what intervention could you use and why The effectiveness of the cilia decreases, Immunoglobulin A decreases, alveolar macrophages are altered | |
