29
Q

What should you test in acute severe asthma in the ED?

A

1) Lung function tests (PEF or FEV1)
2) O2 Sat

30
Q

Which test is reserved for asthma patients who are poorly responsive to initial treatment
or deteriorating?

A

Arterial blood gases

31
Q

The primary therapy of acute exacerbations is pharmacologic, which includes giving all of these concurrently:

A

1) β2-agonists
2) Corticosteroids
3) Inhaled ipratropium
4) O2

32
Q

Why shouldn’t we use sedatives during an asthma attack?

A

Anxiety may be a sign of
hypoxemia = worsened by CNS depressants

33
Q

Should you give antibiotics to a patient suffering from an exacerbation?

A

No, exacerbations are caused by viruses, not bacteria.

34
Q

If a patient presents with an asthma attack and has a very high demand for O2, which organisms should you suspect?

A

1) Mycoplasma
2) Chlamydia

35
Q

Which drugs can be prescribed as maintenance therapy?

A

1) ICS
2) ICS-LABA
3) ICS-LABA-LAMA
4) LTRA
5) Biologic therapy

36
Q

What is asthma maintenance treatment?

A

Drugs prescribed for use every day or on a regular basis even when the patient does not have asthma symptoms

37
Q

What is asthma controller treatment?

A

Targeting both symptom control and future risk

38
Q

Which drugs can be prescribed as controller therapy?

A

ICS-containing relievers

39
Q

What are asthma relievers?

A

Asthma inhalers taken as needed for quick relief of symptoms (rescue inhalers)

40
Q

Which drugs can be prescribed as asthma relievers?

A

1) SABAs
2) ICS-SABA

41
Q

Which drugs can be prescribed as Anti-inflammatory relievers (AIR)?

A

ICS-Formoterol

43
Q

What is the initial treatment of asthma ≥ 6 years of age?

A

ICS-containing treatment at time of diagnosis + reliever inhaler for quick relief of symptoms

44
Q

Which drugs are given as the initial treatment of asthma ≥ 6 years of age?

A

1) Budesonide-formoterol
2) Beclomethasone-formoterol
3) ICS-salbutamol

45
Q

What are the reasons for starting ICS-containing medications?

A

1) Reduction of risk of severe exacerbations and ER visits or hospitalization

2) Early initiation leads to greater improvement in lung function than delayed use

3) Reduction in long-term decline in lung function

4) For patients with occupational asthma

5)

46
Q

In patients with occupational asthma, early removal from exposure to sensitizing agent and early ICS-containing treatment increases the probability of:

A

1) Resolution of symptoms
2) Improvement of lung function
3) Improvement of airway hyper-responsiveness
