NUR 2502 MDC 3 EXAM 2 100% VERIFIED FALL 2022 hyperventilation, if someone is blowing off too much CO2 they become more Correct Answer- Alkaline, respiratory alkalosis if a patient's lung are not f... unctioning very well and they are unable to remove or blow off CO2 very well, the CO2 will build up in their system becoming Correct Answer- acidic, respiratory acidosis Perfusion Correct Answer- is adequate arterial blood flow through the peripheral tissues (peripheral perfusion) and blood that is pumped by the heart to oxygenate major body organs (central perfusion) upper respiratory tract Correct Answer- nose, sinuses, pharynx, larynx Lower respiratory tract Correct Answer- Lungs,Trachea, two mainstem bronchi, lobar, segmental, and subsegmental bronchi; bronchioles; alveolar ducts; alveoli common cause of respiratory ailments Correct Answer- Cigarette smoke Nursing care of a patient experiencing upper respiratory system disorders Correct Answer- maintaining a patent airway to allow adequate ventilation and oxygenation. Along with a focused respiratory assessment, the nurse will utilize information obtained from the patient and family during the admission history interview. Information regarding the patient's history of upper respiratory disorders, smoking, and environmental exposures will be utilized to determine the necessary testing and treatment Normal Changes in Aging Adults Correct Answer- Alveoli function decreases Ability to cough decreases Lungs loose residual volume, vital capacity and gas exchange decreases. Respiratory muscles atrophy Vascular resistance increases, capillary flow decreases Susceptibility to infection increases.The turbinates Correct Answer- three bones that protrude into the nasal cavities from the internal portion of the nose increase the total surface area for filtering, warming, and humidifying inspired air before it passes into the nasopharynx. The paranasal sinuses Correct Answer- air-filled cavities within the bones that surround the nasal passages Lined with ciliated membrane, the sinuses provide resonance to speech, decrease the weight of the skull, and act as shock absorbers in the event of facial trauma.. Fremitus refers to vibratory tremors that can be felt through the chest by palpation, Increased fremitus may indicate Correct Answer- compression or consolidation of lung tissue, as occurs in pneumonia. Lung sounds Correct Answer- Bronchial Bronchovesicular Vesicular Adventitious sounds Correct Answer- Crackles Wheezes Rhonchus Pleural friction rub Other Indicators of Respiratory Adequacy Correct Answer- Cyanosis, decreased capillary refill, clubbing of nails in fingers, level of consciousness, Chest Circumference, Anxiety, Dyspnea Orthopnea, General Appearance Diagnostic Assessment of lungs Correct Answer- Laboratory assessment - RBC - ABG- is a blood gas and this tells us the acid base balance of the patient - Sputum- can tell us if microorganisms are growing in the lung - describe color, clarity, and any odorImaging assessment - x-rays-Xrays show us areas of opaque which usually indicate pneumonia/consolidation of fluid -CT- computed tomography. Lung nodules, areas of fluid buildup Other noninvasive diagnostic assessments - Pulse oximetry-circulating O2- tells us oxygen levels in the tissues- usually fingers, toes, or earlobes - Capnometry and capnography-how much CO2 is leaving the lungs. -PFTs-Lung function- tell us how well the lungs function at moving air in and out - Exercise testing-Exercise tolerance Invasive Diagnostic Assessment Correct Answer- -Endoscopic examinations -Bronchoscopy- is a camera that looks at the airway passages -Thoracentesis- can remove fluid buildup from the lung -Lung biopsy- is used to diagnose some lung diseases or cancer Which assessment finding for an older adult patient does the nurse ascribe to the natural aging process? Correct Answer- A.Tightening of the vocal cords B.Decrease in residual volume C.Decrease in the anteroposterior diameter D.Decrease in respiratory muscle strength D. As a person ages, vocal cords become slack, changing the quality and strength of the voice; the anteroposterior diameter increases; respiratory muscle strength decreases; and the residual volume increases. The nurse knows that under normal physiologic conditions of tissue perfusion, a patient will have what percent of oxygen dissociate from the hemoglobin molecule? Correct Answer- A.25% [Show More]
