Kartegener's syndrome
27
What should a patient with recurrent pulmonary embolisms be screened for?
Thrombophilia screen e.g. factor V Leiden
28
What pulse can be seen in severe asthma and why?
Pulsus paradoxus as there is decreased left atrial filling pressures on inspiration

Which atypical pneumonia can cause dry cough and deranged LFTs?
Legionella
33
How do you treat pulmonary Aspergillosis ?
Amphotericin B
34
What bronchodilator can decrease serum potassium?
salbutamol
35
What is the pulmonary capillary wedge pressure and refractory hypoxaemia like in ARDS?
pulmonary capillary wedge pressure: <18 refractory hypoxaemia PaO2:FiO2 < 200
36
What antibiotics are used to treat aspiration pneumoniae?
IV metronidazole and cefuroxime
37
What are the target oxygen saturations in an asthma attack?
94-98%
38
What symptoms suggest an acute exacerbation of COPD and what medication is prescribed if not admitted to hospital?
increase in dyspnoea, cough, wheeze increase in sputum suggestive of an infective cause patients may be hypoxic and in some cases have acute confusion -> increase bronchodilator use, give prednisolone and Abx only if purulent sputum/ signs of pneumonia
39
What can be seen on a CXR of a TB patient?
scarring at the apices
40
What can a bloody aspiration of a pleural effusion suggest and what investigation is warranted next?
Mesothelioma Pleural biopsy

TB RIPE
42
What is Caplan's syndrome?
Rheumatoid pneumoniosis RA+ peripheral fibrous nodules in the lungs of coal workers
43
If symptoms suggest pneumonia but no consolidation on the CXR what does this mean?
a lower respiratory tract infection
44
If bronchodilators don't help in an acute asthma attack what other medication can be considered?
IV Magnesium sulphate
45
Which attacks is IV theophylline used in?
Acute asthma attacks
46
Which lung cancer can cause a monophonic wheeze?
Non small cell lung cancers e.g squamous cell cancers
47
How is stage 1-2 NSCLC managed? (4cm)
Lobectomy +/- chemotherapy Unfit-> radiotherapy
48
How do you manage a pneumothorax <2cm in a COPD patient who is not breathless?
Needle aspiration
49
Name a mucolytic
carbocysteine
50
How can sun exposure worsen sarcoidosis?
Sarcoid granulomas can activate vitamin D increasing serum calcium
51
When is non invasive ventilation contraindicated and what is given instead?

Towards the affected side
58
In pneumothorax which way does the trachea deviate?

In patients with raised ICP what kind of ventilation may help?
1. sit patient up 2. mechanical hyperventilation decreased CO2 eading to vasoconstriction
60
What imaging is always done first in suspected PE?
CXR to rule out any other differentials
