Chapter 18 : Adrenergic Drugs Questions
Question 1 of 5
The nurse is presenting information to a class of students about adrenergic drugs. Which are the effects of drugs that stimulate the sympathetic nervous system?
Correct Answer: A,D,E,G
Rationale: Stimulation of the sympathetic nervous system causes bronchodilation, increased heart rate, pupil dilation, and glycogenolysis as well as many other effects. The other responses are effects that occur as a result of the stimulation of the parasympathetic nervous system.
Question 2 of 5
The nurse is to administer epinephrine 0.5 mg subcutaneously. The ampule contains 1 mL of medication and is labeled 1 mg/mL. Identify how many milliliters of epinephrine the nurse will give.
Correct Answer: 0.5 mL
Rationale: 1 mg : 1 mL :: 0.5 mg : x mL; (1 * x) = (1 * 0.5); x = 0.5 mL.
Question 3 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 4 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 5 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.
