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.

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 effects of adrenergic drugs on the body. The nurse demonstrates understanding of this group of drugs by identifying that which of the following would occur if the drug stimulates beta-1 receptors?
- A. Vasoconstriction of peripheral blood vessels
- B. Decreased gastrointestinal tract secretions
- C. Increased force of myocardial contractions
- D. Bronchodilation
Correct Answer: C
Rationale: Beta-1 receptor stimulation increases heart rate and myocardial contractility, enhancing cardiac output.
A client is prescribed dopamine. Which of the following would the nurse include in the client's plan of care?
- A. Administering dopamine only via IV route
- B. Maintaining a fixed rate of administration
- C. Monitoring blood pressure every half hour
- D. Diluting dopamine with sodium bicarbonate
Correct Answer: A
Rationale: Dopamine must be administered intravenously to ensure rapid and controlled delivery, with blood pressure monitored frequently to titrate the dose.
A nurse may be asked to administer adrenergic drugs to clients with which of the following conditions?
- A. Hypovolemic shock
- B. Respiratory distress
- C. Severe hypertension
- D. Allergic reactions
- E. Cardiac arrest
Correct Answer: A,B,D,E
Rationale: Adrenergic drugs are used to treat conditions like hypovolemic shock, respiratory distress, allergic reactions, and cardiac arrest by stimulating the sympathetic nervous system. They are contraindicated in severe hypertension.
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.
