Lower Respiratory Tract Exam Flashcards
What is considered to be a normal adult breathing rate?
quiet & regular @ respiratory rate of 14-20/min
What is bradypnea?
regular breathing rhythm but slower than normal rate (RR<14/min)
What is hyperpnea?
When is it normal?
increased depth of breathing & rate of respiration
normal during exercise
What is dyspnea?
feeling short of breath
Atelectasis
collapse of lung tissue that affects the alveoli from normal O2 absorption
Which 2 fingers do you use to percuss the lungs?
hyperextended middle finger of non-dominant hand & tapping finger of dominant hand
Where would you insert a needle for a thoracentesis?
2nd intercostal space & midclavicular line
Where would you insert a chest tube?
4th intercostal space @ mid axillary line (just superior to 5th rib to avoid neurovascular bundle)
Common chief complaints for lung exam
cough coughing & spitting up blood trouble breathing wheezing swelling
What should be considered in HPI for cc related to lungs?
medications
exposure to cold/allergen that triggers asthma
allergic reaction (to meal)
pulmonary infection (cough)
recent surgery increases risk for pulmonary embolism
recent trauma (pneumothorax)
What are some associated symptom considerations for lung cc?
ENT: drainage from ear, otalgia (earache), tinnitis, epistaxis, nasal congestion, swollen lymph nodes, sore throad
Respiratory: chest pain, shortness of breath (asthma, pneumonia)
Constitutional associated symptom considerations
fever
sweats
chills
weight loss
PE of lower respiratory track
Inspection
Palpation
Percussion
Auscultation
Pulse oximetry
measures peripheral arterial oxygen saturation
End Tidal CO2
measures ventilation
non-invasive measurement of partial pressure of CO2 in inhaled breath over time
What is a normal PET CO2 reading?
35-40 mm Hg (represents normal partial pressure of CO2 in arterial blood)
What should you look for during inspection?
assess breathing rate, rhythm, depth & effort
skin color (cyanosis?)
trachea (is it midline)
hands (clubbing?)
shape of chest (deformity?)
What does cyanosis indicate?
hypoxia (can see @ nail bed)
