Study Notes

Respiratory Problem: Care for Clients with Pneumonia

Pneumonia is an acute lung infection affecting gas exchange, causing inflammation of alveoli and fluid accumulation.
Modes of transmission include:
- Airborne Transmission: Caused by respiratory droplets from coughs, sneezes, or talks of an infected person.
- Direct Contact: Involves contact with respiratory secretions or contaminated surfaces.
- Aspiration: Occurs when bacteria from the mouth/throat are inhaled, especially in at-risk populations.
- Healthcare-Associated Transmission: Often seen in patients on mechanical ventilation (VAP).

Pathophysiology of Pertussis

Transmission: Bordetella pertussis bacteria adhere to respiratory epithelial cells via inhalation of droplets from infected individuals.
Toxin Production: Key toxins include pertussis toxin (disrupts immune response) and tracheal cytotoxin (damages ciliated cells).
Inflammatory Response: Leads to severe coughing and mucus production due to cell destruction and toxin activity.

Nursing Responsibilities in Pneumonia Care

Assess Respiratory Function: Monitor coughing fits, respiratory distress, and cyanosis.
Maintain Hydration and Nutrition: Important for patients, especially children who may experience feeding difficulties.
Implement Infection Control: Use droplet precautions; educate families on hygiene practices.
Administer Medications: Macrolide antibiotics for bacterial infection; supportive care with antipyretics and hydration.
Airway Management: Position patients for easier breathing and use supplemental oxygen if needed.

Medical Treatment Approaches

Antibiotic Treatment: Macrolides (azithromycin, clarithromycin) are first-line options; TMP-SMX is an alternative.
Supportive Care: Includes hydration, antipyretics, and oxygen therapy when necessary.
Vaccination: DTaP vaccine for children and Tdap booster for adults to prevent pertussis.

Middle East Respiratory Syndrome Coronavirus (MERS-CoV)

Definition: MERS-CoV is a viral respiratory illness first identified in Saudi Arabia in 2012, affecting individuals primarily in the Middle East but also globally.
Symptoms:
- Common: Fever, cough, shortness of breath, muscle pain, sore throat.
- Severe: Can lead to pneumonia, ARDS, renal failure, and septic shock.
Pathognomonic Signs: No specific signs; diagnosis relies on clinical presentation, travel history, and lab testing.

Transmission of MERS-CoV

Human-to-Human: Transmitted primarily through respiratory droplets and close contact, especially in healthcare settings.
Animal-to-Human: Zoonotic transmission occurs via dromedary camels, considering them major reservoir hosts.
Environmental Factors: Possible indirect transmission through contaminated surfaces.

Pathophysiology of MERS-CoV

Viral Entry: MERS-CoV primarily enters through the respiratory tract and can lead to severe respiratory illness.
