RESPIRATORY Flashcards
severity of airflow obstruction can be graded according to
predicted FEV1 following the use of bronchodilators
severity of airflow obstruction, stages
FEV1 > 80% stage 1 or mild COPD
FEV1 50–79% stage 2 or moderate COPD
FEV1 30–49% stage 3 or severe COPD
FEV1 < 30% stage 4 or very severe COPD
appropriate tool to use for the annual review of asthma in a child aged four years
Childhood Asthma Control Test (or Mini Asthma Quality of Life Questionnaire or Paediatric Asthma Quality of Life Questionnaire)
clinical feature is MOST likely to suggest an alternative diagnosis to chronic obstructive pulmonary disease (COPD)
Haemoptysis
assessment of patients for LTOT should include the measurement of arterial blood gases when
two occasions at least three weeks apart
What is the threshold NUMBER of exacerbations per year, if any, after which long-term antibiotics are recommended for treating adult bronchiectasis?

If inhaled corticosteroids are not controlling a person’s asthma symptoms, then NICE recommendswhat to add
leukotriene receptor antagonist (LTRA)
If inhaled corticosteroids are not controlling a person’s asthma symptoms, then BTS/SIGN recommend
adding in a long-acting beta-2 agonist
acute severe asthma episode is defined as any one of
Peak expiratory flow (PEF) 33–50% best or predicted

NICE) advises that an urgent chest X-ray should be considered to assess for lung cancer in people aged 40 years or over with any of the following
Persistent or recurrent chest infection
Finger clubbing
Supraclavicular lymphadenopathy or persistent cervical lymphadenopathy
Chest signs consistent with lung cancer
Thrombocytosis
indication of endometrial cancer and therefore pelvic ultrasound should be considered in women aged 55 years and over
Thrombocytosis with visible haematuria or vaginal discharge
occupational asthma involves peak flow reading at work and at home twice each for how many weeks
3 weeks
characterised by the development of large conglomerate masses of dense fibrosis usually in the upper lung zones usually caused by methotrexate and rheumatoid arthritis
Progressive massive fibrosis
how many days of antibiotic course should be started for infective exacerbations of bronchiectasis
7-14 days
TEST recommended to confirm a diagnosis of COPD
Post-bronchodilator spirometry
alternative treatment’ for her mild intermittent asthma
Behavioural programmes centred on breathing exercises such as the Buteyko metho
percentage of cases of occupational asthma is caused by sensitiser-induced disease
90
why long-acting muscarinic antagonists (LAMAs) are NOT recommended for people with acute asthma
The onset of bronchodilation is too slow
disease associated with non-cystic fibrosis bronchiectasis
Rheumatoid arthritis
For CAP, patients can expect what to resolve in how many weeks (5x)
One week: the fever should have resolved
Four weeks: the chest pain and sputum production should have substantially reduced
Six weeks: the cough and breathlessness should have substantially reduced
Three months: most symptoms should have resolved but fatigue may still be present
Six months: most people will feel back to normal
Spirometry may under-diagnose and over-diagnose what population
under-diagnose younger adults and over-diagnose elderly patients
Need for LTOT in COPD is assessed by measuring ABG when
on two occasions, at least three weeks apart
In COPD, Long-term oxygen should be offered to those with a partial pressure of oxygen (PaO2) of
< 7.3 kPa when stable or < 7.3 kPa and < 8 kPa when there is associated peripheral oedema, pulmonary hypertension, secondary polycythaemia or nocturnal hypoxaemia, or oxygen saturation levels are 92% or less breathing air
first-line treatment for patients with progressive chronic pulmonary sarcoidosis
Prednisolone
Finger clubbing is suggestive of which dieases (3x)
lung cancer, interstitial lung disease, or bronchiectasis. NOT COPD
risk factors for continuing symptoms of post-acute COVID-19 (4x)
Older age, high BMI, female sex and asthma
When is pulmonary rehabilitation indicated for management of COPD
indicated in patients who have functional impairment or an MRC dyspnoea score of 3 or above
Basic support for patients with COPD (3x)
supported to stop smoking and offered a pneumococcal vaccination and an annual influenza vaccination
Long term oxygen therapy (LTOT) should be prescribed for at least
15 hours a day
high-risk CAP treatment
Co-amoxiclav + clarithromycin
patient on regular low dose ICS + SABA - not working, next step?
Switch to MART
Pulmonary fibrosis spirometry
proportionally reduced FEV1 and FVC, FEV1/FVC>70
GOLD guidelines recommend additional investigations at the diagnosis of COPD with
chest x-ray, pulse oximetry and alpha-1 antitrypsin deficiency screening
The typical COPD patient tends to present at a younger age (<45 years) with
lower lobe emphysema
self-management plan option for exacerbations should be advised for asthma according to NICE
