16
Q

What might tender cervical lymphadenopathy suggest?

A

Upper respiratory tract infection

17
Q

List some features of COPD that can be found on examination.

A

Chest wall deformity (e.g. barrel chest)
Intercostal recession
Signs of right heart failure (peripheral oedema, raised JVP, parasternal heave, tricuspid regurgitation)
Asterixis

18
Q

List some blood tests that may be useful in a patient with cough.

A

ABG – assess progression towards respiratory falure
FBC – signs of infection (high WCC)
CRP
U&Es – check dehydration, urea is a useful way of gaging severity of pneumonia
Blood cultures

19
Q

Why might you perform an ECG in a patient with a cough?

A

AF can occur secondary to pneumonia

Check for signs of right heart strain

20
Q

Which pathogens that cause pneumonia produce antigens that can be detected in the urine?

A

Streptococcus pneumoniae

Legionella pneumophila

21
Q

Why are sputum cultures rarely useful?

A

They are often contaminated by commensal bacteria

22
Q

Which scoring system is used to assess the severity of pneumonia?

A

CURB-65

23
Q

What are the different components of CURB-65?

A
Confusion
Urea
Respiratory rate 
Blood pressure
65+ yrs old
24
Q

List some complications of pneumonia.

A

Pleural effusion
Empyema
Abscess
Septicaemia

25
Q

What are the three most common causes of a chronic cough in non-smokers?

A

Asthma
GORD
Post-nasal drip

26
Q

Why shouldn’t you give 100% oxygen to patients with COPD?

A

It diminishes the hypoxic drive to breathe – this results in the patient becoming very hypercapnic
It also diminishes hypoxic vasoconstriction leading to VQ mismatch
