Q

what are some pretreatment options for individuals with a sulfite induced bronchospasm

A

Cromolyn
Anticholinergics
Cyanocobalamin

22
Q

what causes mast cell degranulation due to a calcium chelation property?

A
Ethylenediamine tetraacetic acid (EDTA)
Stabilizing agent (found in inhalers)
23
Q

can cause a dry, non productive cough May begin within days to 12 months after initiating therapy. Patients have normal spirometry and chest xray

A

ACE inhibitors

24
Q

risk factors for cough due to ACEI

A

Female
Asian descent
Elderly
Heart failure

25
Q

what is thought to cause cough with ACEI

A

accumulate bradykinin which stimulates cough reflex and substance P which causes bronchoconstriction

26
Q

how do you manage cough due to ACEI?

A

discontinue drug and cough will usually resolve
if need to stay on ACEI cough suppressants or bronchodilators don’t work
switch to an ARB

27
Q

what drug in IV formulation can cause cough. Is associated w/ young age and absence of smoking. hx of asthma/ COPD isn’t predictive.

A

fentanyl

28
Q

what is narcotic induced non-cardiogenic pulmonary edema most commonly seen in?

A

IV heroin use

also seen with morphine, methadone, meperidine, propoxyphene

29
Q

what will a patient with narcotic induced non-cardiogenic pulmonary edema present with?

A

Comatose, depressed resps
can have cyanosis and hypoxia
decreased PFTs
appear within minutes- hours of administration

30
Q

when do patients with narcotic induced non-cardiogenic pulmonary edema

A

24-48 hours but PF abnormality may last up to 12 weeks

31
Q

Tx for narcotic induced non-cardiogenic pulmonary edema

A

naloxone
oxygen
ventilatory support

32
Q
Presents with 
Persistent cough
Tachypnea
Dyspnea
Tachycardia
Rales on auscultation
Hypoxemia
Decreased lung compliance
A

Pulmonary edema

33
Q

when is pulmonary edema seen?

A
HCTZ
contrast media
IV bleomycin
Terbutaline
salicylate OD
34
Q

what is pulmonary eosinophilia most often due to?

A

Nitrofuratoin

Para-aminosalicylic acid (topical anti-infective)

35
Q

how does someone with pulmonary eosinophilia present?

A

Fever, nonproductive cough, dyspnea, , cyanosis, bilateral pulmonary infiltrates and eosinophilia in blood

36
Q

when does pulmonary eosinophilia present with nitrofuratoin?

A

w/i 1 month of therapy

will recover within 15 days of DC of med

37
Q

Excessive amount of connective tissue in the interstitial spaces of the lung
Normal airspaces and blood vessels replaced by fibrotic tissue; lungs become small and stiff
Occurs more with higher doses of drugs

A

Chronic pulmonary fibrosis

38
Q

Drugs that cause pulmonary fibrosis

A
Bleomycin 
Busulfan
Carmustine
Methotrexate
Amiodarone
39
Q
Non-productive cough
Acute dyspnea
Tachypnea
Lung crackles
PFTs initially normal then reduce CO2
hypoxemia on ABGs
A

pulmonary fibrosis

40
Q

does pulmonary fibrosis happen immediately or a long time after receiving belomycin?

A

Both

41
Q

what drug can you give to help drug induced pulmonary fibrosis

A

prednisone

42
Q

risks for amiodarone pulmonary toxicity

A

men
increased age
pre-existing lung dz

43
Q

when does amiodarone pulmonary toxicity usually occur?

A

5 weeks- 6 years after initiating therapy

44
Q

what will amiodarone pulmonary toxicity usually quickly progress to?

A

ARDS

45
Q

MOA of amiodarone pulmonary toxicity

A

Accumulation of amiodarone and metabolite in lung tissue
Interfere with normal processing of phospholipids
Breakdown of phospholipid-laden macrophages results in pulmonary inflammation and fibrosis

hard to tell in ventilator dependent patients

51
Q

when do you worry about oxygen toxicity (what percent oxygen)

A

50-100%

52
Q

what lung damage do you see with oxygen toxicity?

A

Acute phase edema with alveolar hemorrhage

leads to fibrosis, lack of exchange
