Question 1 of 5
When describing the autonomic nervous system to a group of nursing students, the instructor determines that the teaching was successful when the students identify which body function as being controlled by this system?
Correct Answer: A,C,D,E
Rationale: The autonomic nervous system regulates involuntary functions such as heart rate, blood pressure, glandular secretions, and gastrointestinal (GI) activity. Muscle movement is primarily controlled by the somatic nervous system.
Question 2 of 5
When describing drugs that block or inhibit the sympathetic nervous system, the nurse includes which of the following?
Correct Answer: A,B,E
Rationale: Antiadrenergic drugs, adrenergic blocking drugs, and sympatholytics are terms used to describe medications that inhibit the sympathetic nervous system by blocking its effects.
Question 3 of 5
A nurse is preparing to administer a sympathomimetic drug. Which of the following might the nurse be preparing to give?
Correct Answer: B,C,D
Rationale: Sympathomimetic drugs mimic the effects of the sympathetic nervous system, such as increasing heart rate and blood pressure. Isoproterenol, midodrine, and epinephrine are examples, while clonidine and reserpine have different mechanisms.
Question 4 of 5
The nurse administers isoproterenol (Isuprel) to a client. Which of the following would most likely occur?
Correct Answer: B,C,E
Rationale: Isoproterenol stimulates beta receptors, leading to increased heart rate, increased glucose metabolism, decreased gastric motility, dilation of coronary blood vessels, and wakefulness.
Question 5 of 5
When describing the adrenergic nervous system, which of the following would the instructor describe as two types of receptors that are found in this system?
Correct Answer: A,B
Rationale: The adrenergic nervous system involves alpha and beta receptors, which mediate the effects of catecholamines like norepinephrine and epinephrine.
