Study Notes

Upper Respiratory Conditions

Inflammation in nasal tissue often leads to chronic inflammation and congestion.
Common physical exam findings include nasal congestion, turbinate hypertrophy (boggy and pale), clear drainage, and throat redness due to post nasal drip.
Lung exams are generally normal and ears should appear unaffected.
Diagnostic tests might show elevated eosinophils and basophils in CBC; allergy testing can involve skin tests or specific IgE testing.
Management includes minimizing symptoms, reducing inflammation, limiting medications, and increasing tolerance to triggers.
Second-generation antihistamines like Zyrtec, Clarinex, and Allegra are preferred for their safety and efficacy in reducing secretions and itching but are ineffective against congestion.
Decongestants require caution in patients with cardiovascular issues, hypertension, or diabetes, and are essential for all sinusitis cases.

Influenza (Flu)

Influentially contagious disease, affecting 5-20% of the population annually with approximately 20,000 deaths and 200,000 hospitalizations yearly.
Influenza types:
- A: Infects both animals and humans; capable of quick mutations.
- B and C: Exclusively human infections.
Transmission can occur via animal-human contact, contaminated surfaces, or fecal material, with peak risk from 1 day before symptoms to 5-7 days afterward.
The incubation period is typically 1-4 days.
Goals of treatment focus on preventing complications like pneumonia and sinusitis, which can occur due to blockages in the sinus mucosa from inflammation.
Chronic sinusitis and potential bacterial infections are complications, commonly associated with dental abscesses and allergic triggers.

Pharyngitis

Characterized by inflammation of the pharynx, can be acute bacterial, viral, or chronic (often noninfectious).
Physical signs include varying throat redness and possible exudate, particularly with strep infections that present with white patches.
Treatment differs: viral pharyngitis focuses on symptom relief, while bacterial infections require antibiotics like penicillin or erythromycin for patients allergic to penicillin.
Throat care includes fluids, mouth care, and in bacterial cases, targeted antibiotic therapy.

Lower Respiratory Problems

Acute Bronchitis

Predominantly viral, characterized by inflammation of the bronchi, lasting up to 3 weeks with symptoms like cough, fever, and malaise.
Physical exam may reveal rhonchi or crackles, with treatment aimed at symptom relief.

Pneumonia

Acute lung inflammation from infections, varying types include community-acquired, hospital-acquired, aspiration, and opportunistic pneumonia.
Symptoms include fever, cough (with or without sputum), chills, and possible shortness of breath, especially in elderly patients.
Diagnostic tests entail chest X-ray, CBC, and sputum culture, while nursing management focuses on respiratory assessment, medication administration, and patient support.

Tuberculosis

Chronic infectious disease mostly impacting lungs, marked by inflammatory responses to TB nuclei imprinted in alveoli.
Pathophysiology includes immune reactions leading to scar and granuloma formation.

Chronic Respiratory Conditions

Chronic Bronchitis

Defined by excessive mucus production and productive cough lasting over 3 months, with structural airway changes.
Key symptoms include dyspnea, increased respiratory rate, and tenacious sputum.

Emphysema

Permanent enlargement of airspaces distal to bronchioles, correlating with bronchial wall destruction.
Loss of elastic recoil and increased airway resistance lead to symptoms like dyspnea, barrel chest, and accessory muscle use.

Diagnostic Tests for COPD

Bronchoscopy allows visualization of lungs using a camera to assess and sample lung tissue.
Chest X-rays and pulmonary function tests (PFT) evaluate lung volumes, highlighting discrepancies in FEV1/FVC ratios indicative of obstructive versus restrictive diseases.

PFT Findings in COPD

Decreased FEV1 often indicates airflow restriction, with a corresponding lowered FEV1/FVC ratio.
TLC measures total inspiratory capacity; obstructive patterns reveal air trapping and reduced FEV1 with a decreased ratio.
Restrictive patterns show decreased FEV1 and FVC while maintaining a normal FEV1/FVC ratio.

General Examination

Monitoring lung sounds through percussion and auscultation provides additional diagnostic information on respiratory conditions.
