1. How do adrenergic drugs act to relieve symptoms of acute bronchospasm, anaphylaxis, cardiac arrest, hypotension, and shock, and nasal congestion?
Bronchospasm:
Adrenergic drugs stimulate beta2-adrenergic receptors causing bronchodilation
How do adrenergic drugs act to relieve symptoms of acute bronchospasm, anaphylaxis, cardiac arrest, hypotension, and shock, and nasal congestion?
Anaphylaxis:
Adrenergic drugs stimulate alpha1-receptors causing vasoconstriction; beta1, increasing heart rate and force of contraction; and beta2, causing bronchodilation
Cardiac arrest, hypotension, and shock: Adrenergic drugs stimulate alpha1 receptors, causing vasoconstriction; and beta1, increasing heart rate and force of contraction
Nasal congestion: Adrenergic drugs constrict arterioles and reduce blood flow to the nasal mucosa

2. Which adrenergic receptors are stimulated by administration of epinephrine?
Alpha and beta receptors are stimulated by epinephrine.

They are the drugs of choice in emergency situations of acute cardiovascular, respiratory, and allergic disorders.
4. Which adrenergic drug is the drug of choice to treat acute anaphylactic reactions?
Epinephrine is used because it relieves -------------, laryngeal ---------, and ----------- quickly. It acts as a physiologic antagonist of histamine and other bronchoconstricting and vasodilating substances released during anaphylaxis.

7. Why are clients with cardiac dysrhythmias, angina pectoris, hypertension, or diabetes mellitus especially likely to experience adverse reactions to adrenergic drugs?
Adrenergic drugs stimulate beta1 receptors that increase heart rate and force of contraction; alpha1 receptors cause vasoconstriction. Adrenergic drugs also stimulate glyconeogenesis and gluconeogenesis.
8. For a client who reports frequent use of OTC asthma remedies and cold remedies, what teaching is needed to increase client safety?
Rebound nasal congestion is possible with the overuse of ------------- agents. Clients with conditions that might be affected by adrenergic drugs should ---------- them. Clients should be made aware that there is an ------------- effect if they are using more than one product with an adrenergic agent.
9. For a client who reports frequent use of OTC asthma remedies and cold remedies, what teaching is needed to increase client safety?
Rebound nasal congestion is possible with the overuse of OTC adrenergic agents. Clients with conditions that might be affected by adrenergic drugs should avoid them. Clients should be made aware that there is an additive effect if they are using more than one product with an adrenergic agent.
9. Mentally rehearse nursing interventions for various emergency situations (anaphylaxis, acute respiratory distress, cardiac arrest) in terms of medications and equipment needed and how to obtain them promptly.
Nursing interventions always include an appropriate assessment of the ---------, maintaining a patent airway, -------------, and ----------- (if necessary). Alert clients should be placed in high Fowler’s if they are in acute respiratory distress and
in Trendelenburg if they are in shock.
9. Mentally rehearse nursing interventions for various emergency situations (anaphylaxis, acute respiratory distress, cardiac arrest) in terms of medications and equipment needed and how to obtain them promptly.
Nursing interventions always include an appropriate assessment of the ABCs, maintaining a patent airway, ventilation, and compressions (if necessary). Alert clients should be placed in high Fowler’s if they are in acute respiratory distress and in Trendelenburg if they are in shock.
