What drug enhances the output of respiratory tract fluid by reducing the adhesiveness and surface tension of the fluid which facilitates the removal of viscous mucus?
Guaifenesin.
Dextromethorphan.
Acetylcysteine.
Flunisolide.
The Correct Answer is A
Choice A rationale
Guaifenesin is an expectorant that increases the output of respiratory tract fluid by reducing the adhesiveness and surface tension of the mucus, facilitating the removal of viscous mucus.
Choice B rationale
Dextromethorphan is a cough suppressant that works on the cough center in the brain to reduce the urge to cough. It does not enhance the output of respiratory tract fluid.
Choice C rationale
Acetylcysteine is a mucolytic that breaks down the chemical structure of mucus molecules, making the mucus less viscous, but it does not enhance the output of respiratory tract fluid by reducing adhesiveness.
Choice D rationale
Flunisolide is an inhaled corticosteroid used to reduce inflammation in the airways. It does not enhance the output of respiratory tract fluid.

Correct Answer is D
Explanation
Choice A rationale
Vitamin E is an antioxidant and is not indicated to counteract the effects of warfarin. It does not have a role in reversing anticoagulation or managing bleeding. High doses of Vitamin E can actually interfere with clotting and potentially exacerbate bleeding.
Choice B rationale
Protamine Sulfate is an antidote for heparin, not warfarin. It works by neutralizing the effects of heparin, which is an anticoagulant that acts quickly to prevent clot formation. Warfarin works differently and requires a different antidote for its anticoagulant effect.
Choice C rationale
Calcium Gluconate is not an antidote for warfarin. It is typically used in cases of hypocalcemia and can stabilize cardiac membranes in hyperkalemia but has no effect on reversing warfarin-induced anticoagulation or bleeding.
Choice D rationale
Vitamin K is the correct antidote for warfarin. It counteracts the anticoagulant effects by promoting the synthesis of clotting factors that warfarin inhibits. Administering Vitamin K is standard practice in reversing the effects of warfarin and managing bleeding complications.
Correct Answer is D
Explanation
Choice A rationale
Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease characterized by obstructed airflow from the lungs. While related to respiratory health, it is distinct from tuberculosis.
Choice B rationale
Bronchiectasis is a condition involving the permanent enlargement of parts of the airways of the lung, often caused by infection or other lung conditions but is different from tuberculosis.
Choice C rationale
Emphysema is a chronic lung condition where the alveoli (air sacs) are damaged, leading to breathing difficulties. This condition is usually associated with smoking and is distinct from tuberculosis.
Choice D rationale
Consumption is an old term for tuberculosis, reflecting the wasting away (consuming) nature of the disease due to the progressive weight loss and weakness it causes.
