Pulmonology Flashcards
Which chest X-ray view(s) should be ordered for this ambulatory patient? With 4 days sickness productive cough and temp of 101.4?
PA and lateral views
Why PA and lateral views for chest xray for pt with respiratory sx?
PA = minimizes anterior features of the heart
Lateral= helps us see fluid line in the lungs
The patient’s chest X-ray report indicates “an opacity in the left lower lobe.” What is the nurse practitioner’s interpretation?
Pneumonia
Your patient is a 52-year-old man with pneumonia. He denies shortness of breath. Should he get an antibiotic?
yes
Pneumonia Abx recommendations for pt without comorbidities
Amoxicillin 1 gram three times daily (strong recommendation, moderate quality of evidence), OR
Doxycycline 100 mg twice daily (conditional recommendation, low quality of evidence), OR
Macrolide (azithromycin 500 mg on first day, then 250 mg daily or clarithromycin 500 mg twice daily or clarithromycin ER 1,000 mg daily) only in areas with macrolide resistance <25% (conditional recommendation, moderate quality of evidence).
Which 5-day antibiotic regimen is most likely to produce GI upset?
- Amoxicillin 1 gram three times daily
- Doxycycline 100 mg twice daily
- Azithromycin 500 mg once, then 250 mg daily for 4 days
- These are all well tolerated
- Doxycycline 100 mg twice daily
Recommended to take on empty stomach for absorption but causes GI upset
What should be avoided by patients who take doxycycline?
- Milk Products (wait 1-2 hours bc affects absorption)
- Pregnancy (can cause discoloration to fetal tooth enamel)
- Prolonged exposure to sunlight
Treatment of CAP for outpatient adults WHO HAVE comorbidities:
(chronic heart, lung, liver, or renal disease; diabetes mellitus; alcoholism; malignancy; or asplenia)
Monotherapy:
▪ Respiratory fluoroquinolone (levofloxacin 750 mg daily, moxifloxacin 400 mg daily, or gemifloxacin 320 mg daily)
▪ Strong recommendation, moderate quality of evidence
Combination therapy:
▪ Amoxicillin/clavulanate or a cephalosporin (cefpodoxime 200 mg twice daily or cefuroxime 500 mg twice daily); PLUS
▪ Macrolide or doxycycline
Strong recommendation, moderate quality of evidence for combination with macrolide
Conditional recommendation, low quality of evidence for combination therapy with doxycycline
Which antibiotic should NOT be used to treat CAP in a patient who has comorbidities? Why
- Levofloxacin
- Moxifloxacin
- Ciprofloxacin
- Gemifloxacin
Ciprofloxacin= not a respiratory fluoroquinolone … only kills bugs below the belt
Which antibiotic should NOT be used to treat CAP in a patient who has comorbidities? Why
- Levofloxacin
- Moxifloxacin
- Ciprofloxacin
- Gemifloxacin
Ciprofloxacin= not a respiratory fluroquinolone … only kills bugs below the belt
issues might contraindicate use of a quinolone in a patient who has CAP?
Pregnancy= bone/ cartilage formation
Hx of QT prolongation – can make worse
Abdominal Aortic Aneurysm = can cause to develop/ rupture
Dehydration
CrCl <30 mL/min – kidneys excrete quinolones
How long to continue abx for pneumonia?
5-10 days … usually
Consider age, comorbidities
Is a follow-up chest Xray necessary for follow-up?
Not necessary if responding appropriately and symptom resolution n 5-7 days
What pneumococcal vax should generally adults greater than or equal to 65 receive
If immunocompromised?
PPSV23 (recommended) OR “shared decision making:”
PCV13 plus PPSV23
Diagnosis of COPD made when:
Risk factors present:
Tobacco
Occupation
Pollution exposure
