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
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)
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
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%
B.50%
