The nurse is caring for a client who is terminally and approaching the end of life. Which goal would the nurse identify as the priority?

To increase hydration

To control symptoms

To promote nutrition

To limit environmental hazards

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is A

Explanation

A. It indicates a normal depolarization of the atria: A PR interval of 0.12–0.20 seconds is within the normal range, representing normal conduction through the atria and AV node.

B. It provides information about atrial repolarization: Atrial repolarization is obscured by the QRS complex and not reflected in the PR interval.

C. It shows an early indication of first-degree heart block: First-degree heart block is indicated by a PR interval longer than 0.20 seconds.

D. It reflects a delayed conduction through the atria: A delay in conduction would result in a prolonged PR interval.

A. Suppresses ectopic ventricular sites B. Increases SA node automaticity C. Increases myocardial contractibility D. Decreases AV node conduction

Correct Answer is B

Explanation

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.
