List 2 contraindications of Bupropion and 2 side effects
CI: Seizure disorder, ETOH withdrawal, bulemia/anorexia, linezolid/MOA inhibitors, hepatic impairment
Side effects: lowers seizure threshold, insomnia, dry mouth, tremor
What are the stages of smoking cessation
Pre-contemplative – not ready, unaware of need to change, do not intend to change in 6m
Contemplative – ready to quit in 6m
Preparation – ready to quit in 30d, have taken steps
Action – quit in last 6m
Maintenance – quit > 6m
List 2 CXR and 2 PFT changes of radiation pneumonitis?
2 CXR Findings:
- can be normal
- Perivascular haziness -> patchy alveolar filling densities.
- straight-line effect, which does not conform to anatomical 🡪 diagnostic of RILI.
2 PFT Findings:
Reduction in lung volumes (TLC, FVC, RV).
Tidal volumes decreased, and the respiratory rate may be elevated.
DLCO reduced.
List 4 factors of radiation pneumonitis?
*Volume of lung irradiation.
*Dose of radiation.
Time-dose factor.
Method of irradiation.
Concurrent chemotherapy.
*Younger age.
*Smoking history.
Poor ECOG prior to treatment.
* = similar to risk factors of bleomycin
COPD.
Female.
ILD.
2 features of methotrexate induced lung toxicity
What is the incidence?
1-10% incidence
1, - HP (Most common) – loose granulomas, lymphocytic infiltration, +/- eosinophilic infiltration
2. Organizing pneumonia
3. AIP (acute interstitial pneumonitis with non-cardiogenic pulmonary edema)
4. Pulmonary fibrosis
Typically at the bases
5. Effusion/pleuritis
6. Pulmonary infections (PJP, CMV, Nocardia, mycobacteria,
7. Pulmonary lymphoproliferative disease — Lymphoproliferative disease (including non-Hodgkin [B cell] and other lymphomas)
Risk factors for MTX lung toxicity
- Age > 60
- pre-existing lung disease
- renal disease, low albumin diabetes
- higher dose

list two mechanisms by which tocolytics can cause pulmonary edema (terbutaline, albuterol given during preterm labor)
- decreased ventricular filling time, increase HR
- increase capillary permeability
- dramatic reflex increase in vessel tone when discontinued after birth is successful, with fluid overload due to fluid shifts in immediate post partum period
