37
Displacement of the apex beat from its usual location can occur due to? [1]
**Displacement** of the **apex** **beat** from its usual location can occur due to **ventricular hypertrophy**.
38
How do you test for heaves and thrills?
**Heave**: * Place the heel of your hand parallel to the left sternal edge (fingers vertical) to palpate for heaves. **Thrill**: * **horizontally** across the chest wall, with the flats of your fingers and palm over the valve to be assessed.
39
What lung ascultation would indicate pulmonary oedema? [1]
**Coarse crackles** are suggestive of pulmonary oedema (associated with left ventricular failure).
40
What would suggest pleural effusion on ascultation of lung fields?
**Absent air entry** and stony dullness on percussion are suggestive of an underlying pleural effusion (associated with left ventricular failure).
41
What assessing for in eyes of resp exam? [1]
**Horners syndrome**: due to lung cancer at apex of lung
42
Lymph nodes?

43
When might you see changes in inspiratory / exp phase of inhalation [2]
the **expiratory** **phase** is often **prolonged** in **asthma** exacerbations and in patients with **COPD**).
44
Things looking for when assessing mouth in resp?
**Central cyanosis:** bluish discolouration of the lips and/or the tongue associated with hypoxaemia. **Oral candidiasis**: a fungal infection commonly associated with steroid inhaler use (due to local immunosuppression). It is characterised by pseudomembranous white slough which can be easily wiped away to reveal underlying erythematous mucosa.
45
Reasons for symmetrical reduced chest expansion? [3] Reasons for asymmetrical reduced chest expansion? [3]
**Symmetrical**: pulmonary fibrosis reduces lung elasticity, restricting overall chest expansion. **Asymmetrical**: pneumothorax, pneumonia and pleural effusion would all cause ipsilateral reduced chest expansion.
46
When assessing breath sounds, how would you describe: Quality of breath sounds? [2] Volume of breath sounds? [1] Added sounds? [4]
47
Why can second heart sound split?
The difference in timing between the closure of the aortic and pulmonary valves physiological: during inspiration intrathoracic pressure increases, increases venous return, pulmonary valve closes slightly later. pathological: LBBB and aortic stenosis cause the aortic valve closure to be delayed
48
reasons for a pulse deficit?
difference between the apical and radial pulse rates due to eg. **atrial fibrillation**
49
where do you find posterior tibial pulse

50
resp causes of wasting of small hand muscles?
lung cancer involving the brachial plexus
51
What is this sign? [1]
**Xanthomata** are raised yellow cholesterol-rich deposits that are often noted on the palm, tendons of the wrist and elbow. Xanthomata are associated with **hyperlipidaemia** (typically familial hypercholesterolaemia), an important risk factor for cardiovascular disease.
52
Reasons for Dupuytren’s contracture? [4]
