Nafcillin
What is first line treatment for MRSA?
Vancomycin
If you cant use vancomycin for MRSA, what is next best?
Linezolid
Two penicillin variants for gram negative?
Amoxicillin and ampicillin
What beta lactamase inhibitor do we give with ampicillin and amoxicillin?
Amp is sulbactam
Amoxicillin is clavulanate
What cillin are we using for pseudomonas and what is its beta lactamase?
Pipercillin and tazobactam
What do you use if you dont use pip tazo?
Carbapenem
What gram stain bacteria do 1,2,3,4 cephalosporins cover?
1,2 more positive
3 both
4, negative and pseudo
4th generation cephalosporins to know?
2 3rd generation to know?
Cefapime
Cefotaz and ceftriaxone
2 symptoms that are the backbone of lung infection or point you to lung infection?
Cough and fever
Fever and cough positive chest x ray equals?
Fever and cough negative chest x ray equals?
Fever and cough and cavitation on chest x ray equals?
Pneumonia
Bronchitis
Abscess
2 criteria for community acquired pneumonia?
1 criteria for healthcare/hospital acquired pneumonia?
Greater than 90 days from exposure to health care building
Or
Less than 48 hours from being admitted to hospital
Less than 90 days from exposure to the building
6 organism causing CAP and their context?
Strep pneumonia Klebsiella, alcoholic H flu, COPD M cat, Staph, post viral Legionella, immune system sucks
What are the two options to treat community acquired pneumonia?
when to use moxi?
Ceftriaxone and azithromycin in hospital
Just azithroymycin outside of hopsital
Moxi if beta lactam allergy
Top 2 dogs causing HAP?
What to use to treat them?
Pseudo and staph
Pip tazo and vancomycin (linezolid or meropenem if those arent available)
Top 2 things to do when someone comes in with cough and fever?
Chest x ray and pulse ox
If the x ray is negative, what do they have and how to treat?
Bronchitis (basically not as bad pneumonia)
Azithromycin or doxycycline or moxi
What happens if the chest x ray shows cavitation and there is foul smelling sputum, what do you do next?
CT to see if its fungus, TB, or abscess
Empiric treatment for abscess?
Ceftriaxone an clindamycin
What if the x ray shows consolidation, how do we proceed?
Need to figure out time of exposure to building and determine HAP vs. CAP.
Let’s say you have a patient with HIV/AIDS and pneumonia, what is the pathogen, how do you diagnose and what do you give to treat?
PCP
Sputum silver stain
TMP-SMX plus or minus steroids based on hypoxia, SOB, dyspnea
What is the curb 65 criteria used for and how do we use it?
See how to treat/manage pneumonia. Each one gets a point. Confusion, BUN over 20, Respiratory over 30, BP under 90/60, and over 65.
1 point outpatient
2 inpatient
3 and over admit, and consider ICU for 4 and 5
3 symptoms to remember for flu and which one will distinguish it from pneumonia?
