,hyperventilation, if someone is blowing off too much CO2 they become more - Answer: Alkaline,
respiratory alkalosis
if a patient's lung are not functioning very well and they are unable to remove or blow off CO2 very well,
the CO2 will build up in their system becoming - Answer: acidic, respiratory acidosis
Perfusion - 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 - Answer: nose, sinuses, pharynx, larynx
Lower respiratory tract - Answer: Lungs,Trachea, two mainstem bronchi, lobar, segmental, and
subsegmental bronchi; bronchioles; alveolar ducts; alveoli
common cause of respiratory ailments - Answer: Cigarette smoke
Nursing care of a patient experiencing upper respiratory system disorders - 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 - 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 - 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 - 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 - Answer: compression or consolidation of lung tissue, as occurs in pneumonia.
Lung sounds - Answer: Bronchial
Bronchovesicular
Vesicular
Adventitious sounds - Answer: Crackles
Wheezes
Rhonchus
Pleural friction rub
Other Indicators of Respiratory Adequacy - Answer: Cyanosis, decreased capillary refill, clubbing of nails
in fingers, level of consciousness, Chest Circumference, Anxiety, Dyspnea Orthopnea, General
Appearance
Diagnostic Assessment of lungs - 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 odor
Imaging 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 - 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?
- 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? - Answer: A.25%
B.50%
C.75%
D.100%
