The nurse administers isoproterenol (Isuprel) to a client. Which of the following would most likely occur?
- A. Decreased heart rate
- B. Increased use of glucose
- C. Decreased gastric motility
- D. Constriction of coronary blood vessels
- E. Wakefulness
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.

A nurse is reviewing the different types of shock that may occur. The nurse demonstrates understanding of the information when the nurse identifies which of the following as a type of distributive shock?
- A. Cardiogenic-obstructive shock
- B. Septic shock
- C. Hypovolemic shock
- D. Anaphylactic shock
- E. Neurogenic shock
Correct Answer: B,D,E
Rationale: Distributive shock includes septic, anaphylactic, and neurogenic shock, characterized by widespread vasodilation and maldistribution of blood flow. Cardiogenic and hypovolemic shock are not distributive.
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.
Before administering dobutamine to a client, the nurse should assess which of the following?
- A. Blood pressure
- B. Blood glucose
- C. Respiratory rate
- D. Pulse
- E. Level of consciousness
Correct Answer: A,C,D,E
Rationale: Dobutamine administration requires monitoring of blood pressure, respiratory rate, pulse, and level of consciousness to assess cardiovascular and neurological status.
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 nurse is preparing to administer a prescribed adrenergic agent to a client who is in shock. Before administering the drug, the nurse would assess for and document which of the following as a sign of shock?
- A. Increased temperature
- B. Reddish/pinkish skin
- C. Dry, dehydrated skin
- D. Changes in consciousness
Correct Answer: D
Rationale: Changes in consciousness are a key sign of shock, indicating inadequate cerebral perfusion, and should be documented before administering adrenergic drugs.
