Study Notes
Tuberculosis (TB) Quiz - Study Notes
-
Primary Cause of TB: Mycobacterium tuberculosis, a bacteria that spreads through aerosolization.
-
Granulomatous Lesion Formation: Inflammation with the formation of tubercles (granulomas) through the accumulation of macrophages and neutrophils, isolating the bacteria.
-
Latent TB: Bacteria are dormant, enclosed in scar tissue, and non-infectious. They are not completely eliminated from the body.
-
Risk Factors for Active TB: Recent travel to high-incidence countries is the greatest risk factor. Compromised immune systems, drug use, and immigration from high-risk areas are also significant factors.
Diagnosis and Testing
-
Tuberculin Skin Test (TST): An induration greater than 15mm is considered positive in healthy adults with no risk factors.
-
Definitive TB Diagnosis: Sputum culture is the definitive diagnostic test.
-
IGRAs (Interferon-Gamma Release Assays): IGRAs are unaffected by BCG vaccination and can detect TB infection, but cannot confirm active disease. Results are not affected by prior BCG vaccinations.
Medications and Treatment
-
Vitamin B6 Supplementation: Isoniazid requires vitamin B6 supplementation to prevent peripheral neuropathy.
-
Pyrazinamide Side Effects: Nurse should emphasize monitoring for hepatotoxicity (liver damage) when teaching about pyrazinamide.
-
Multiple Medications: Multiple medications are used to prevent antibiotic resistance in TB. Combining multiple drugs is more effective at preventing the bacteria from developing resistance.
Nursing Care and Management
-
Infectiousness of TB: A client with active TB is infectious until adequate treatment is given and cultures of sputum are negative.
-
Priority Nursing Diagnosis: The priority nursing diagnosis for active TB is ineffective airway clearance, as TB primarily affects the lungs. Maintaining lung function is extremely important.
Prevention and Public Health
-
BCG Vaccine: The BCG vaccine can cause a false positive TST, but does not provide lifelong immunity.
-
TB Transmission: TB transmission is primarily through airborne particles, making poor ventilation and direct contact significant risk factors.
-
PPE for TB Care: N95 respirators are essential PPE for nurses caring for clients with active TB.
Miscellaneous
-
Multi-drug Resistant TB (MDR-TB): Incomplete or inconsistent TB treatment increases the risk of developing MDR-TB.
-
Liver Function Tests: Routine liver function tests are essential during TB treatment to monitor for potential hepatotoxicity (liver damage) associated with some TB medications.
-
Symptom Prioritization: Hemoptysis (coughing up blood) is a critical symptom during TB treatment that requires immediate attention. A persistent cough with blood can indicate complications.
