hyperventilation, if someone is blowing off too much CO2 they become more—
Correct 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—
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 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— 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
