Chapter 18 : Adrenergic Drugs Questions
Question 1 of 5
The nurse is preparing to administer dopamine. Which is the correct technique for administering dopamine?
Correct Answer: D
Rationale: Dopamine is available only as an IV injectable drug and is given by continuous infusion, using an infusion pump. The other options are incorrect.
Question 2 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 3 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 4 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 5 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.
