Answer 1

Questions 1

Answer - D. Breathing has improved.

As the name suggests, bronchodilators act by dilating lung airways. Bronchodilators do not increase secretions. Sputum is less viscous by drugs called mucolytics Ex:ambroxol. Sedation is a side effect caused by the use of chlorpheniramine maleate which is employed as an adjunct in severe asthma.

Question 2

Answer - D. Rise in blood pressure, anxiety, cardiac arrhythmias.

A few examples sympathomimetic bronchodilators include salbutamol and albuterol. These act as beta adrenergic agonists & bring about bronchodilation. The side effects are also due to stimulation of beta adrenergic receptors.

Question 3

Answer - A. Prophylactic

Sodium cromoglycate or cromolyn is a Mast cell stabilizer. It acts by preventing mast cells from degranulating inflammatory mediators, thus preventing the action of these inflammatory mediators & hence preventing bronco constriction. Ideally, they must be used as a prophylactic before the allergens causing mast cell degranulations are encountered.

Question 4

Answer A. Caffeine

An example of xanthine bronchodilator is theophylline. In our body caffeine is metabolised to theophylline. Theophylline is a drug with a narrow therapeutic index (has more side effects when taken in higher concentrations). Therefore drinking caffeine when using theophylline must be avoided as it increases the blood theophylline concentration.

Question 5

Answer - A

Its the standard procedure. It ensures good bioavailability.
