DH206 Chapter 17 Respiratory part 1

Asthma is characterized by irreversible airway obstruction and is associated with a reduction in expiratory airflow. Chronic obstructive pulmonary disease (COPD) is characterized by reversible airway obstruction, such as in chronic bronchitis or emphysema.

• The first statement is true; the second statement is false.

• The first statement is false; the second statement is true.

All of these medication groups are used in treatment of asthma except; which is the exception?

• Cholinergic agents

• β2-Adrenergic agonists

• Mast cell stabilizers (Cromlyn)

• Corticosteroids

Which components of asthma must be treated to control the disease?

• Inflammation

  Bronchoconstriction

• Bronchodilation

• Alveolar destruction

• All of the above

In __________, patients have persistent life-threatening bronchospasm despite drug therapy.

• chronic bronchitis

• status asthmaticus

• intermittent asthma

• chronic obstructive pulmonary disease (COPD)

• emphysema

Which treatment considerations should the dental health care worker make for patients with asthma?

• Low stress protocol during the dental appointment.

• Low stress protocol during the dental appointment.

• Observe and question the patient before the appointment to prevent an acute asthma attack.

Chronic obstructive pulmonary disease (COPD) is associated with which factors or conditions?

• Chronic bronchitis

• Smoking

• Emphysema

• All of the above

Which medications are used in the management of emphysema?

• Antimuscarinics

• β2-Adrenergic agonists

• Corticosteroids

• Xanthines

• All of the above

Which are the advantages of the metered-dose inhaler (MDI)?

• Medication is delivered directly to bronchiole, reducing the total dose and systemic adverse effects.

• Increased secretions

• Vasoconstriction of arterioles

• Increased blood pressure in lungs

• Bronchodilation by stimulation of β receptors of lungs
