Chapter 18 : Adrenergic Drugs Questions
Question 1 of 5
The nurse is aware that adrenergic drugs produce effects similar to which of these nervous systems?
Correct Answer: C
Rationale: Adrenergic drugs mimic the effects of the sympathetic nervous system.
Question 2 of 5
When an adrenergic drug stimulates beta-adrenergic receptors, the result is an increased heart rate, which is known as what type of effect?
Correct Answer: C
Rationale: A positive chronotropic effect is an increased heart rate. An increased force of contraction is known as a positive inotropic effect. Positive dromotropic effect is an increase in the conduction of cardiac electrical nerve impulses through the atrioventricular node.
Question 3 of 5
When a patient is taking an adrenergic agonist drug, the nurse expects to observe which effect?
Correct Answer: B
Rationale: Increased heart rate is one of the effects of adrenergic drugs. Sympathetic nervous system stimulation also results in bronchodilation, dilated pupils, and decreased gastrointestinal motility, depending upon which receptors are stimulated.
Question 4 of 5
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?
Correct Answer: B
Rationale: 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.
Question 5 of 5
The nurse is administering a stat dose of epinephrine. Epinephrine is appropriate for which situation?
Correct Answer: C
Rationale: Treatment of cardiac arrest is an indication for the use of epinephrine. The other options are not indications for epinephrine.
