Q

how do you investigate symmetrical lung inflation?

A

Q

what would decrease lung expansion?

Study These Flashcards
A

lung disease

e.g. pneumonia, collapsed lung

21
Q

what would cause a unilateral decrease?

Study These Flashcards
A

pleural effusion

22
Q

what would cause a bilateral decrease?

23
Q

how do you investigate breathing pattern and breathing rate?

Study These Flashcards
A
  • I’m going to have a look at your breathing, is that okay with you?
  • count number of breaths for 30 seconds, multiply by 2
  • is breathing pattern regular/irregular?
24
Q

what does rapid shallow breathing suggest?

Study These Flashcards
A

hyperventilation episodes, interstitial lung disease

25
what does a prolonged expiratory phase suggest?
significant airway obstruction | e.g. asthma, COPD
26
What is Kussmaul's respiration?
rapid, deep, sighing breathing pattern "air hungur" caused by acidosis e.g. diabetic ketoacidosis
27
where do you percuss the upper lobe on the anterior chest wall?
1. medial 1/3 of clavicle directly onto bone | 2. any point below clavicle and above 4th rib
28
where do you percuss the upper lobe on the posterior chest wall?
at level of T1 and T3 b/ scapular line and vertebral column
29
where do you percuss the middle lobe of R lung?
on anterior chest wall - 4th or 5th ICS (just under nipple for men) - just below axilla at MAL
30
where do you percuss the lower lobe on the anterior chest wall?
6th ICS near MAL | just under base of breast in females
31
where do you percuss the lower lobe on the posterior chest wall?
anywhere b/ scapula to T10 | 8th rib at scapular line
32
when is a resonant sound heard?
lung is air filled
33
when is a dull sound heard?
presence of fluid | when tissue density is increased
34
when is a flat sound heard?
solid in pleural space
35
when is a hyperresonant sound heard?
pneumothorax
36
before auscultation, what do you need to do?
1. consent 2. stethoscope on the correct way 3. ensure diaphragm is engaged by lightly tapping on it
37
where do you auscultate the upper lobe on the anterior chest wall?
1. lung apex - above medial 1/3 clavicle | 2. any point on ant chest wall below clavicle and above 4th rib
38
where do you auscultate the upper lobe on the posterior chest wall?
upper back near scapula spine (level T3)
39
where do you auscultate the middle lobe of the R lung?
anterior chest wall 1. 5th ICS at MCL (just under nipple for men) 2. just below axilla at MAL
40
where do you auscultate the lower lobe on the anterior chest wall?
6th or 7th ICS near MAL | just under base of breast
41
where do you auscultate the lower lobe on the posterior chest wall?
anywhere b/ scapula to T10 | e.g. 8th rib at scapular line
42
before demonstrating the safety triangle, what do you need to ask the pt to do?
ask pt to move the hand to the back of their head on the side you are going to demonstrate it on
43
what is the posterior border of the safety triangle?
anterior border of latissimus dorsi
44
what is the anterior border of the safety triangle?
lateral border of pectoralis major
45
what is the inferior border of the safety triangle?
5th ICS at MAL
46
what is the superior border of safety triangle?
below apex of axilla
47
why is this the "safety triangle"?
can insert a chest drain here without damaging any nearby nerves e.g. long thoracic nerve
48
where does the triangle of safety overlie?
2nd to 5th ICS
