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 C

Explanation

A. Deficits in the right visual field: This would be associated with a left-sided stroke, as the right hemisphere controls the left visual field.

B. Motor retardation: This is not a specific sign of right hemisphere stroke. It might be seen with other types of strokes.

C. Poor impulse control: A right hemisphere stroke may cause behavioral changes, including impulsivity, poor judgment, and difficulty in regulating emotions.

D. Unable to discriminate words and letters: This would suggest aphasia, which is typically associated with left hemisphere damage, as the left hemisphere controls language.

A. A patient with second-degree atrioventricular (AV) block, type 1. rate 60, who is dizzy when ambulating B. A patient who is in a sinus rhythm, rate 98 and regular, recovering from an elective cardioversion 2 hours ago C. A patient with atrial fibrillation, rate 88 and irregular, who has a dose of warfarin (Coumadin) due D. A patient whose implantable cardioverter-defibrillator (ICD) fired twice today and has a dose of amiodarone (Cordarone) due.

Correct Answer is D

Explanation

A. A patient with second-degree atrioventricular (AV) block, type 1, rate 60, who is dizzy when ambulating. While dizziness may be a concern, second-degree AV block type 1 (Wenckebach) typically resolves without immediate intervention.

B. A patient who is in a sinus rhythm, rate 98 and regular, recovering from an elective cardioversion 2 hours ago. This patient is stable, and recovery from cardioversion typically involves monitoring, but the patient does not require immediate intervention.

C. A patient with atrial fibrillation, rate 88 and irregular, who has a dose of warfarin (Coumadin) due. The patient is stable, and the dose of warfarin can be administered after assessing the patient’s overall condition, making it a lower priority.

D. A patient whose implantable cardioverter-defibrillator (ICD) fired twice today and has a dose of amiodarone (Cordarone) due: The patient whose ICD fired twice is at high risk for life-threatening arrhythmias, and this situation requires immediate evaluation and intervention. The nurse should assess the patient first, and the dose of amiodarone may be administered to manage any underlying arrhythmias.
