MULTIPLE CHOICE

 

1. The nurse is aware that adrenergic drugs produce effects similar to which of these nervous systems?

a.	Central nervous system
b.	Somatic nervous system
c.	Sympathetic nervous system
d.	Parasympathetic nervous system

 

 

ANS:  C

Adrenergic drugs mimic the effects of the sympathetic nervous system.

2. When an adrenergic drug stimulates beta₁-adrenergic receptors, the result is an increased force of contraction, which is known as what type of effect?

a.	Positive inotropic
b.	Anti-adrenergic
c.	Negative dromotropic
d.	Positive chronotropic

 

 

ANS:  A

An increased force of contraction is known as a positive inotropic effect.

3. When a patient is taking an adrenergic drug, the nurse expects to observe which effect?

a.	Increased heart rate
b.	Bronchial constriction
c.	Constricted pupils
d.	Increased intestinal peristalsis

 

 

ANS:  A

Increased heart rate is one of the effects of adrenergic drugs. Sympathetic nervous system stimulation also results in bronchodilation, dilated pupils, and decreased gastrointestinal mobility, depending upon which receptors are stimulated.

4. An adrenergic agonist is ordered for a patient in shock. The nurse will note that this drug has had its primary intended effect if which expected outcome occurs?

a.	Volume restoration
b.	Increased cardiac output
c.	Decreased urine output
d.	Reduced anxiety

 

 

ANS:  B

For a patient in shock, a primary benefit of an adrenergic agonist drug is to increase cardiac output. A drug in this category should not be used in place of volume restoration, nor does it provide volume restoration (IV fluids do this). Adrenergic agonists may enhance urine output if cardiac output and perfusion to the kidneys increase. These drugs do not reduce anxiety.
