A 40-year old patient presents with symptoms suggestive of tuberculosis (TB). What is the confirmatory test for TB?
Interferon Gamma Release Assays (IGRAS)
Sputum culture
Tuberculin Skin Test (TST)
Chest X-ray
The Correct Answer is B
A. Interferon Gamma Release Assays (IGRAs): IGRAs are useful for detecting TB infection but do not confirm active TB disease. They measure the immune response to TB bacteria but don’t differentiate between latent and active infection.
B. Sputum culture: Sputum culture is the gold standard for confirming active TB because it identifies Mycobacterium tuberculosis bacteria directly, confirming active infection.
C. Tuberculin Skin Test (TST): The TST can indicate TB infection but cannot distinguish between latent and active TB, making it unsuitable as a confirmatory test for active disease.
D. Chest X-ray: A chest X-ray can show signs suggestive of TB but cannot confirm the presence of TB bacteria, so it is not definitive for diagnosing active TB.

Correct Answer is A
Explanation
A. Increased pulse, respirations and blood pressure with dysphagia and respiratory distress. A myasthenic crisis is characterized by severe muscle weakness that can lead to respiratory failure, dysphagia, and increased vital signs due to the stress of respiratory distress.
B. Hypotension, diarrhea, and increased salivation. These symptoms are more indicative of a cholinergic crisis, which is due to excess acetylcholine.
C. Bradycardia and hypothermia. Bradycardia and hypothermia are not characteristic signs of a myasthenic crisis.
D. Tachypnea and hyperactive deep tendon reflexes. While tachypnea can occur in respiratory distress, hyperactive reflexes are not typical in myasthenic crisis, as it involves neuromuscular weakness.
Correct Answer is A
Explanation
A. Drink plenty of fluids to stay hydrated. Staying hydrated is essential in managing viral pharyngitis to prevent dehydration, soothe the throat, and promote recovery.
B. Take antibiotics as prescribed until the course is complete. Antibiotics are not indicated for viral infections; they are only used for bacterial infections.
C. Avoid all forms of physical activity until fully recovered. While rest is recommended, light activities may be acceptable depending on the patient’s energy levels and symptoms. Total avoidance of all physical activity is unnecessary.
D. Use throat lozenges as needed but avoid resting to prevent throat swelling. Resting is beneficial to recovery. Throat lozenges may soothe irritation, but avoiding rest would be counterproductive.
