Exam 2 - Upper Respiratory Infections Flashcards
1
Q
simple (acute) bronchitis
A
- inflammation of the bronchi and bronchioles
- etiology: bacterial or viral infection
- NO AIRFLOW OBSTRUCTION
- presentation: usually mild and self-limited/requires only supportive care
- prognosis: good, usually better in 3-4 weeks
2
Q
chronic bronchitis
A
- bronchitis for 3 months out of the year for at least 2 years
- etiology: cigarettes
- AIRFLOW OBSTRUCTION = a form of COPD
- presentation: may have acute exacerbation of chronic bronchitis
- prognosis: premature morbidity and mortality
3
Q
clinical symptoms of acute bronchitis
A
- often begins as a common cold
- sore throat (pharyngeal erythema)
- nasal discharge (rhinorrhea)
- muscle aches
- PERSISTENT COUGH (can last 3 weeks)
- wheezing in severe cases
- sputum production in most patients
- enlarged lymph nodes
4
Q
diagnosis of acute bronchitis
A
- based mostly on symptoms and physical assessment
- CBC to distinguish bacterial from viral infection
5
Q
treatment of acute bronchitis
A
- broad spectrum antibiotics for bacterial infection
- expectorants
- cough suppressants
6
Q
histamines
A
- stored in mast cells (skin and soft tissue) and the basophils (blood)
7
Q
what can histamines cause when activated
A
- hives and itching
- dilation of blood vessels resulting in erythema and hypotension
- bronchoconstriction - shortness of air
- affect sleep/wake cycles
- increase the secretion of acid in the stomach
8
Q
what causes the majority of the symptoms associated with allergic reactions
A
- histamine
9
Q
what is allergic rhinitis
A
- inflammatory disorder
10
Q
clinical manifestations of allergic rhinitis
A
- sneezing
- rhinorrhea
- pruritis
- nasal congestion
- watery, itchy eyes
11
Q
how is allergic rhinitis triggered
A
- by allergens
- bind to IgE antibodies on mast cells and release inflammatory mediators
12
Q
what are some environmental triggers for allergic rhinitis
A
- dust mites
- mold
13
Q
acute sinusitis
A
- an infection of the facial sinuses and membranes of the nose
- inflammation causes the sinus cavity to become obstructed by fluid accumulation and edema allowing for bacterial growth and infection
14
Q
etiology: acute sinusitis
A
- may accompany an URI, nasal polyps, deviated septum or allergic reaction
- viral duration is 5-7 days
- bacterial duration is up to 4 weeks
15
Q
side effects for acute sinusitis
A
- h/a
- facial pain or pressure over sinus area
- nasal obstruction
- fatigue
16
Q
treatment for acute sinusitis
A
- antibiotics
- decongestants
- antihistamines
- mucolytic agents to decrease secretions
17
Q
epiglottitis clinical diagnosis
A
- inspiratory stridor and retractions
- rapid onset of fever
- pain
- difficulty swallowing
- drooling
- ABSENCE OF BARKING COUGH DIFFERENTIATES FROM CROUP
18
Q
epiglottis
A
- rare, but life-threatening infection
- causes sudden swelling of the epiglottis
- without treatment, the epiglottis can become so large that it blocks the windpipe, making it hard to breath
- can be fatal
19
Q
symptoms of epiglottis
A
- drooling and difficulty managing saliva in the mouth
- severe sudden sore throat
- stridor
- SOA especially when laying down
- muffled voice
20
Q
what is a bronchospasm
A
- sudden constriction of the bronchial muscles making breathing difficult
