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?
- A. Alpha receptors
- B. Beta receptors
- C. Delta receptors
- D. Gamma receptors
- E. Omega receptors
Correct Answer: A,B
Rationale: The adrenergic nervous system involves alpha and beta receptors, which mediate the effects of catecholamines like norepinephrine and epinephrine.

A client is to receive midodrine. Which of the following would the nurse include in the plan of care to ensure that the client doesn't develop supine hypertension?
- A. Administer midodrine during the day.
- B. Ensure that the client is lying in a supine position.
- C. Instruct the client to regularly shift positions.
- D. Assist the client when moving out of bed.
Correct Answer: A
Rationale: Administering midodrine during the day reduces the risk of supine hypertension, which is more likely when the client is lying down for extended periods.
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?
- A. Heart rate
- B. Muscle movement
- C. Blood pressure
- D. Glandular secretions
- E. GI activity
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.
After administering dobutamine to a client, the nurse would assess the client closely for which adverse reaction?
- A. Cardiac arrhythmias
- B. Urinary retention
- C. Elevated temperature
- D. Sleeplessness
Correct Answer: A
Rationale: Dobutamine commonly causes cardiac arrhythmias, such as bradycardia or tachycardia, due to its beta-adrenergic stimulation.
A client has been administered dobutamine. The client is also receiving a beta-adrenergic blocking drug. The nurse would monitor the client for the development of which of the following resulting from the use of these two drugs?
- A. Bradycardia
- B. Hypertension
- C. Depression
- D. Dehydration
Correct Answer: B
Rationale: The combination of dobutamine and beta-blockers can lead to hypertension due to unopposed alpha-adrenergic effects when beta receptors are blocked.
After teaching a group of nursing students about adrenergic drugs and their effects, the instructor determines that the teaching was successful when the students identify which of the following as an effect of these drugs?
- A. Decreased myocardial contractility
- B. Vasodilation
- C. Increased cardiac output
- D. Improved airway clearance
Correct Answer: C
Rationale: Adrenergic drugs increase myocardial contractility and heart rate, leading to increased cardiac output.
