The nurse obtains a health history from a patient with a prosthetic mitral value. Which question by the nurse would help to identify a risk factor for infectious endocarditis

Have you had any immunizations recently?

Have you had any dental work done recently?

Do you have a family history of endocarditis?

Have you every suffered a heart attack?

Answer and Explanation

The Correct Answer is B

A. Have you had any immunizations recently?: Immunizations are not associated with a significant risk of infectious endocarditis.

B. Have you had any dental work done recently?: Dental procedures can introduce bacteria into the bloodstream, posing a risk for endocarditis, especially in clients with prosthetic valves.

C. Do you have a family history of endocarditis?: Endocarditis is not typically hereditary; risk factors are more related to procedures, infections, or valve abnormalities.

D. Have you ever suffered a heart attack?: While a history of a heart attack is relevant to cardiac health, it does not directly increase the risk for infectious endocarditis.

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.

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.
