The nurse explains to a client that drugs that activate beta 2-adrenergic receptors:
1. relax bronchiolar smooth muscle.
2. result in airway diameter narrowing.
3. increase labored breathing
4. decrease production of viscous secretions.
Correct Answer: 1
Rationale 1: Drugs that activate beta 2-adrenergic receptors cause bronchiolar smooth muscle to relax.
Rationale 2: Drugs that activate beta 2-adrenergic receptors result in airway diameter increasing.
Rationale 3: Drugs that activate beta 2-adrenergic receptors increase airway diameter resulting in increased ease of breathing.
Rationale 4: Drugs that activate beta 2-adrenergic receptors do not affect the production of viscous secretions.
Global Rationale: Beta2-adrenergic agonists are used to relieve and prevent the bronchospasm that is a characteristic pathophysiological feature of asthma. Airway diameter is increased, decreasing work of breathing. Viscosity of secretions is not affected.
