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 ["A","B","C","D"]

Explanation

A. Hypothermia: Hypothermia can slow the heart rate, leading to bradycardia.

B. Calcium channel blockers medications: These medications can slow the conduction through the AV node, causing bradycardia.

C. Athletic conditioning: Athletes often have a lower resting heart rate due to increased parasympathetic tone, which can lead to sinus bradycardia.

D. Beta-blocker medications: Beta-blockers decrease heart rate by blocking the effects of adrenaline on the heart.

E. Hyperthyroidism: Hyperthyroidism usually leads to tachycardia, not bradycardia, due to increased metabolism.

A. Insertion of central venous access B. Phlebotomy C. Fasciotomy D. Insertion of arterial line

Correct Answer is C

Explanation

A. Insertion of central venous access: This is not relevant to compartment syndrome management. Central venous access is used for fluid administration or monitoring central venous pressure.

B. Phlebotomy: This is unrelated to the management of compartment syndrome, as it involves drawing blood and does not address the increased pressure.

C. Fasciotomy: Compartment syndrome is a medical emergency where increased pressure within a closed compartment compromises circulation and tissue function. A fasciotomy involves surgically opening the compartment to relieve the pressure, prevent tissue necrosis, and save the limb. This is the definitive treatment.

D. Insertion of arterial line: While this may be useful for monitoring blood pressure in critical situations, it does not relieve compartment syndrome.
