Q

Lady with history of asthma stopped her salbutamol and fluticasone a month ago because asthma was sweet as. Moved into a new house recently and now asthma not so sweet as. Able to speak in full sentences, RR ?20-30. As well as restarting her inhalers what other medicine is useful for managing this exacerbation?
a. LAMA
b. LABA
c. Oral montelukast
d. Dust mite desensitization
e. Oral prednisone

A

Oral prednisone

The mainstay of treatment during the acute attack is supplementary oxygen, repeated inhaled bronchodilator and systemic corticosteroids

Q

Old lady with COPD. increasing SOB, taking Salbutamol prn only - increasing use over last ?6 months. Investigations show the current presentation is not due to infective exacerbation but progression of her COPD. ? next step in management.

Theophylline
Prednisone
Montelukast

Q

20 year old male, heavy smoker came in with pleuritic chest pain and dyspnoea. On exam, dull on percussion R lower lobe. Bronchial breath sounds R middle zone. Absent breath sounds R lower zone. What’s the most likely cause?
R lower lobe collapse
R lower lobe consolidation
Pleural effusion.
Tension pneumothorax

A

R lower lobe consolidation

note tht bronchial sounds aren’t normal - sounds overly well transmitted to the chest wall as a consequence of increased sound transmission through the consolidated lung parenchyma

Q

Right sided pleural effusion. Albumin 16 in effusion, 36 (N) in blood. What caused the effusion?
- Cardiac failure
- nephrotic syndrome
- bronchial carcinoma
- renal failure
- other cancers
- pneumonia
- pulmonary infarct

A

this is a transudate not exudate so a systemic balance, something to do with pressure imbalances.

Must be heart failure, as nephrotic syndrome would have LOW albumin.

A

Acute on chronic respiratory failure

I think there is moderate change in pH relative to the increase in CO2.

CTPA

want to see where blood is flowing in lungs

33

but still RR 24 and struggling, sats 97%

A

oral prednisone to get on top of attack

35
Q

Pneumonia + hyponatremia

A

Legionnaires–> atypical pneumonia with cough, SOB, fever, muscle pains, headaches and low Na+

Low sodium via ADH release! Very unusual.

36

bronchogenic carcinom

A

bronchogenic carcinoma

37
Q

20 year old woman with asthma. Previously well controlled on salbutamol + fluticasone, but she stopped a month ago due to being symptom free for ages. Moved into a new house recently and now having an asthma flare. Able to speak in full sentences, RR 24, sats 97%. Has had 6 puffs of Ventolin with no spacer over 4 hours. For acute management on exacerbation, what would you add to control this episode?
a) LAMA
b) LABA
c) Oral montelukast
d) Dust mite desensitization
e) Oral prednisone

A

Oral prednisone

This is mild asthma exacerbation

38
Q

Man with dyspnoea. Has T2DM and asthma. ABG: pH 7.1 (low), CO2 60 (high), HCO3 24 (N). Interpretation?

A

Acidosis

Caused by high CO2 = resp acidosis

N HCO3 so no metabolic compensation

38
Q

Patient with chronic cough with sputum. Spirometry obstructive (FEV1/FVC ratio below LLN). Non-reversible with bronchodilators.
a) Interstitial lung disease
b) Reversible airway disease
c) Anxiety
d) COPD

A

Both asthma + COPD obstructive pattern, but COPD not reversible

Restrictive patterns: pulmonary fibrosis

39
Q

60 year old Indian lady with worsening breathlessness due to right pleural effusion. Aspirate of effusion albumin 16 (low), serum albumin 36 (normal). Normal creatinine. What is the cause of her symptoms?
a) Lung cancer
b) Pneumonia
c) Chronic heart failure
d) Nephrotic
e) Nephritic
f) Mesothelioma
g) Metastatic

A

We know this is a transudate not an exudate. therefore caused by pressure imbalances across the pleura…. CHF (as albumin low in serum in nephrotic!!)

Differentials - cirrhosis

40
Q

What are causes of exudate?

A

malignany, infection (parapneumonic), PE

41
Q

Man in 80s with history of idiopathic pulmonary fibrosis with background of COPD. Has been on salbutamol and oral steroid have not helped previously. 2 day history of SOB at rest. X-ray shows small pleural effusion at edge of chest. Has sats of 96% on air What do you do to immediately relieve SOB?
a) Morphine
b) Theophylline c) Oxygen
d) Oral steroid e) Drain effusion

A

?morphine… palliative

IPF acute exacerbation
- O2 if <88% sats
- Glucocorticoids
- Palliative strategies reduce SOB – opioid, relaxation, fan?ma

42
Q

40 year old Asian man, non-smoker, 3 year history of coughing up green phlegm with blood streaks. Worse in winter. Has clubbing and coarse crackles. Diagnosis?

a) Bronchiectasis
b) Chronic Bronchitis
c) Bronchiolitis
d) COPD

A

Bronchiectasis

Bronchiectasis = recurrent lung infection 􏰀 damaged and enlarged bronchi 􏰀 mucus build in space 􏰀 unable to be cleared by cilia 􏰀 prone to infection
- Sx: chronic productive cough, smelly green-yellow sputum, haemoptysis, clubbing, dyspnoea, usually feel well
- Exacerbations: fever, fatigue, night sweats

43
Q

X-ray of lady with 25 pack year history showed left lung base consolidation. Shortness of breath, dry cough, also had 4 weeks leg pain and bilateral proximal leg weakness. Further investigations?
a) Bronchoscopy
b) Lung biopsy
c) CT chest
d) Sputum cytology

A

Sounds like cancer

CT chest, guides a biopsy

44
Q

Man feels fatigued, falls asleep at work is embarrassed and falls asleep in traffic. Large BMI. Reason?
a) Anaemia
b) Obstructive sleep apnoea
c) Central sleep apnoea
d) Narcolepsy

A

Obstructive sleep apnoea

45
Q

Guy with COPD. pH 7.1, HCO3 high, CO2 high, PO2 low.
a) Acute on chronic respiratory failure.
b) Type 1 respiratory failure
c) Type 2 respiratory failure

A

Hypoxia and hypercapnia

With ACUTE ON CHRONIC

COPD basically gave him chronic hypercapnia (type II) which will have been compensated to maintain normal pH, exacerbation has caused type I failure (hypoxia)

46
Q

Man has VQ scan which shows mismatch. Next management? a) CTPA
b) CXR c) ECG

A

CTPA

VQ mismatch could signal a PE

47
Q

Thoracic duct injury causing SOB. Dx? a) Chylothorax
b) Aspiration pneumonia

A

Chylothorax = disruption of the thoracic duct 􏰀 leakage of chyle (lipid rich lymph) into pleural space.

48
Q
A

Diaphragmatic rupture 􏰀 stomach herniate into chest 􏰀 NG tube in chest

49
Q
A
