The nurse is caring for a client with advanced coronary artery disease who has developed cardiac arrest. During the resuscitation, the health care provider prescribes atropine. Which is the intended outcome of this medication?

Suppresses ectopic ventricular sites

Increases SA node automaticity

Increases myocardial contractibility

Decreases AV node conduction

Answer and Explanation

The Correct Answer is B

A. Suppresses ectopic ventricular sites: Atropine primarily increases heart rate; it does not directly suppress ectopic ventricular activity.

B. Increases SA node automaticity: Atropine blocks the parasympathetic nervous system, increasing SA node activity and heart rate in cases of bradycardia or asystole.

C. Increases myocardial contractility: This effect is more related to drugs like inotropes (e.g., dopamine), not atropine.

D. Decreases AV node conduction: Atropine actually increases conduction through the AV node by blocking vagal stimulation.

Correct Answer is B

Explanation

A. To increase hydration: This is not a priority in terminal care. In fact, increasing hydration can be uncomfortable for dying patients who are often unable to process fluids effectively.

B. To control symptoms: The primary focus in end-of-life care is to manage symptoms, such as pain, difficulty breathing, and anxiety, to ensure the patient is as comfortable as possible.

C. To promote nutrition: At the end of life, promoting nutrition is usually not the priority, as the client may no longer desire food and may be unable to tolerate it.

D. To limit environmental hazards: While important, it is not the priority in terminal care. The focus should be on comfort and symptom control.

A. Amiodarone B. Dopamine C. Adenosine D. Atropine E. Norepinephrine F. Epinephrine

Correct Answer is ["B","E","F"]

Explanation

A. Amiodarone: This is an antiarrhythmic, not a vasopressor.

B. Dopamine: Dopamine has vasopressor effects, increasing blood pressure and cardiac output.

C. Adenosine: This is used to treat supraventricular tachycardia, not for vasopressor purposes.

D. Atropine: Atropine increases heart rate by inhibiting parasympathetic activity but is not a vasopressor.

E. Norepinephrine: Norepinephrine is a potent vasopressor that increases systemic vascular resistance and blood pressure.

F. Epinephrine: Epinephrine has vasopressor and inotropic effects, making it critical during cardiac arrest.
