question

Sigh

answer

Occasionally normal, frequent may indicate emotional dysfunction, hyperventilation and dizziness

question

Tachypnea

answer

Rapid, shallow breathing. Increased rate of 24+, response to fever, fear, exercise, respiratory insufficiency, pneumonia, alkalosis, pleurisy and lesions in the pons

question

Bradypnea

answer

Slow breathing, decreased but regular rate of 10 or less per minute. Seen with drug induced depression of respiratory system, diabetic coma and increased intracranial pressure

question

Hyperventilation

answer

Increase in both rate and depth. Occurs width extreme exertion, fear, anxiety, hepatic coma, ketoacidosis, decreased CO2 level in blood

question

Hypo ventilation

answer

Irregular shallow pattern caused by overdose of narcotics or anesthetics, prolonged bed rest or splinting of chest

question

Cheyne-strokes respiration

answer

cycle in which respirations gradually wax and wane in a regular pattern, increasing in rate and depth and then decreasing. Breathing periods = 30-45 seconds w 20 seconds of apnea causes are heart failure, renal failure, drug OD

question

T or F are cheyne-strokes respirations normal in infants or the elderly

answer

True

question

Biot Respiration

answer

Cycle length of normal respirations with apnea variable. Caused by head trauma, heat stroke, spinal meningitis

question

chronic obstructive breathing

answer

normal inspiration and prolonged expiration to overcome increased airway resistance. Can lead to dyspneic episode

question

types of discontinuous sounds

answer

Fine crackles, coarse crackles, atelectatic crackles and pleural friction rub

question

types of continuous sounds

answer

wheeze (high pitched), wheeze (low pitched) and stridor

question

fine crackles

answer

high pitched, short crackling, popping sounds heard during inspiration that are not cleared by coughing. Seen with pneumonia, heart failure, COPD, bronchitis, asmatha, emphysema and changing from sitting to supine

question

Coarse crackles

answer

loud, low pitched bubbling/gurgling sounds that start early in inspiration. May decrease with suctioning but re appear quickly. Velcro fastener sounds. Seen with pulmonary edema, pneumonia, pulmonary fibrosis, and the terminally ill

question

Atelectatic crackles

answer

fine crackles that don't last and that are not pathologic, disappear after a few breaths. Seen in aging adults, bed ridden patients of people aroused from sleep

question

Pleural friction rub

answer

Superficial sound that is course and low pitched, sounds like 2 pieces of leather being rubbed together. Seen with pleuritis along with pain with breathing

question

Wheeze (high pitched)

answer

high pitched, musical squeaking sounds that are predominant in expiration but sometimes also in inspiration. Caused by diffused airway obstruction from acute asmatha or chronic emphysema

question

Wheeze (low pitched)

answer

low pitched, single note musical snoring/moaning sounds heard more predominantly in expiration. Caused by bronchitis, single bronchus obstruction from airway tumor

question

Stridor

answer

high pitched, monophonic inspiratory crowing sound, louder in neck than in chest. Seen with croup and acute epiglottis in children or foreign inhalation

question

Atelectasis

answer

Collapsed shrunken section of alveoli or an entire lung as a result of an (1) airway obstruction (2) compression on the lung and (3) lack of surfactant Inspection- Cough, lag on expansion on affected side. Increased respiratory rate and pulse. Possible cyanosis. Palpation- Chest expansion decreased on affected side. Tactile fremitus decreased or absent over area. With large collapse, tracheal shift affected side. Percussion- Dull over area Auscultation- Breath sounds decrease vesicular or absent over area. Adventitious Sounds- None if bronchus is obstructed. Occasional fine crackles if bronchus is patent

question

Lobar Pneumonia

answer

Infection in lung parenchyma that leaves alveolar membrane porous causing RBC's and WBC's to pass to the alveoli. Alveoli fill up with debris which replaces alveolar air History- Fever, cough with pleuritic chest pain, blood tinged sputum, chills, SOB, fatigue Inspection- increased respirations 24+, lag expansion on infected side w/ nasal flaring Palpation- Chest expansion decreased on affected side. Tactile fremitus increased if bronchus patent, decreased if obstructed Percussion- dull over lobar pneumonia Auscultation- Tachycardia w/ loud bronchial breathing Adventitious sounds- Crackles: fine-medium

question

Acute Bronchitis

answer

an acute infection of the trachea and larger bronchi characterized by cough, lasting up to 3 weeks. Epithelium of bronchi are inflamed and damaged. Large airways become narrowed from capillary dilation, increased mucus, lack of cilia Inspection- Cough is productive or nonproductive. Sore throat, low grade fever, postnatal drip, fatigue Palpation- No pain or increased fremitus Percussion- Resonant Auscultation- May be clear an equal Adventitious sounds- No crackles

question

Chronic Bronchitis

answer

Proliferation of mucus glands in the passageways resulting in excessive mucus secretion, inflammation of the bronchi, Chronic bronchitis caused by smoking. Inspection- Hacking, rasping cough with thick sputum, cyanosis, clubbing dyspnea Palpation- Fremitus normal Percussion- Resonant Auscultation- Normal vesicular Adventitious sounds- crackles over deflated areas w/ possible wheeze

question

Emphysema

answer

Caused by destruction of pulmonary connective tissue causing permanent enlargement of air sacs. Caused mainly by cigarette smoking Inspection- Barrel chest, accessory muscles used, tripod position, SOB, tachypnea Percussion- Hyper resonant Auscultation- Decreased breath sounds. May have pro-longed expiration, muffled heart sounds. Adventitious sounds- none, occasional wheeze

question

Asthma

answer

Allergic hypersensitivity to certain allergens, irritants, microbes or exercise. Causes complex bronchospasm and inflammation in walls of bronchioles. Inspection- SOB w audible wheeze, accessory neck muscles, cyanosis, chronic= barrel chest Palpation- Tactile fremitus decreased, tachycardia Percussion- Resonant Auscultation- Breath sounds decreased Adventitious sounds- Bilateral wheezing on expiration

question

Pleural effusion

answer

Collection of excess fluid in the intrapleural space, with compression of overlying lung tissue. Gravity causes fluid to settle in dependent areas of thorax Inspection- increased respirations, dyspnea, tachycardia, cyanosis, abdominal distention Palpation- Tactile fremitus decreased or absent. Tracheal shift away from affected side and chest expansion decreased on affected side Percussion- dull Auscultation- Breath sounds decreased or absent Adventitious Sounds- Crackles, pleural rub

question

Heart Failure

answer

Pump failure with increasing pressure of cardiac overload causes pulmonary congestion or an increased amount of blood in pulmonary capillaries. Inspection- Increased respirations, SOB on exertion, orthopnea, paroxysmal nocturnal dyspnea, nocturia, ankle edema Palpation- Moist, clammy. Tactile fremitus normal Percussion- Resonant Auscultation- Normal vesicular, S3 gallop Adventitious sounds- Crackles at lung bases

question

Pneumothorax

answer

Free air in pleural spaces causes partial or complete lung collapse. Can be (1) spontaneous, (2) traumatic- enters through injury or (3) tension Inspection- Unequal chest expansion, tachypnea, cyanosis Palpation- Tactile fremitus decreased or absent Percussion- Hyper resonant Auscultation- Breath sounds decreased or absent Adventitious sounds- none

question

Lung Cancer

answer

Fatal, major cause is tobacco smoking followed by secondhand smoke exposure. Subjective- Fatigue, nausea, vomiting, persistent cough, anorexia, dull localized chest pain Inspection- Weight loss, clubbing, anemia, hemoptysis Auscultation- Wheezing, atelectasis

question

Where do the lower lobes reach down to upon expiration/inspiration

answer

Expiration: T10 Inspiration: T12

question

4 major functions of respiratory system

answer

1) supplies oxygen 2) removes CO2 3) maintains homeostasis 4) maintains heat exchange

question

Bronchial breath sounds

answer

Heard over trachea and larynx

question

Bronchovesicular breath sounds

answer

anteriorly heard at bifurication posteriorly heard at C7-T5

question

Vesicular breath sounds

answer

heard in complete areas of the lungs

question

Accessory neck muscles

answer

sternomastoids, scalene and trapezii

question

T or F right lung has 3 lobes and is shorter than left

answer

True
