N202: Test I

An active process caused by the drop of the diaphragm and the expansion of the intercostal muscles. Inspiration
Typically a passive process mainly caused by elastic recoil of the diaphragm. Expiration
When you breathe in, the: Diaphragm contracts and the chest expands
When you breathe out, the: Chest contracts and the diaphragm relaxes
As you increase in age, the # of cilia decrease, which increases: The risk for infection
As you increase in age, alveoli lose elasticity, which increases: The resistance to airflow and decreases O2 carrying capacity
As you increase in age, muscle mass decreases, which increases: The work of breathing and pt. fatigues more easily
Slow respiratory rate, <10 bpm Bradypnea
Fast respiratory rate, > 24 bpm, usually depth is shallow Tachypnea
Absence of breathing Apnea
Regular but abnormally deep breaths with increased rate Kussmaul's respirations
Air under subcutaneous tissue Crepitus
Fluid in the outside layer of the lungs Peural effusion
Tubular sound heard over the trachea. Expiration > Inspiration Bronchial
Soft swishing lung sound. Inspiration > Expiration Vesicular
Mixture of Bronchial and vesicular sounds. Inspiration = Expiration Bronchovesicular
Fine or course popping noises usually heard on inspiration: Crackles or Rales
Constricted bronchioles, not taking deep breaths or atelectasis can cause: Decreased breath sounds
Course, continuous sounds heard during expiration: Rhonchi
High pitched, musical sounds heard on inspiration & expiration: Wheezing
If you hear crackles with pneumonia: they disappear when the pt. coughs
If you hear crackles with CHF: the crackles remain when the pt. coughs.
Rhonchi always means: Mucous
Wheezing can be heard with: Asthma, COPD, sometimes CHF
The most important breath sound to know is: Stridor
Collapsed alveoli Atelectasis
Collapsed lung Pneumothorax
If there is no air flow in the lungs, pneumothorax, there would be: Absent breath sounds
When inflammation of the pleura, lining of the lungs, is present, what would be heard? Friction rub
If you auscultated a pt.'s lungs and heard the sound of leather rubbing together, what would you document your findings as? Friction rub
If you hear decreased breath sounds in a resting patient, you should first: Tell the pt. to take several deep breaths and auscultate again
You will hear high pitched sounds on inspiration, possibly audible from the door Stridor
Hearing this lung sound usually signifies there is an obstruction: Stridor
If you hear this lung sound and the pt. appears cyanotic and is gasping for breath, this is a medical emergency - scream for help! Stridor
If you hear decreased breath sounds in a resting patient, you should first: Tell the pt. to take several deep breaths and auscultate again
