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 D

Explanation

A. Administration of prescribed Atropine. Atropine is typically used for bradycardia related to second-degree heart block Mobitz 2 or complete block, but Mobitz 1 usually resolves on its own and does not require atropine unless symptoms develop.

B. A prescription for transcutaneous pacing. Transcutaneous pacing is typically used for more severe types of heart block, such as Mobitz 2 or third-degree block, not Mobitz 1.

C. An extra dose of digoxin will be prescribed. Giving additional digoxin would be contraindicated due to its effects on AV conduction.

D. The next dose of digoxin will be held: Second-degree heart block Mobitz 1 (also known as Wenckebach) can be worsened by digoxin, which has a vagomimetic effect that can slow conduction through the AV node. Therefore, the next dose of digoxin should be held to avoid further exacerbating the block.

A. Junctional tachycardia B. Sinus tachycardia C. Atrial flutter D. Ventricular fibrillation

Correct Answer is B

Explanation

A. Junctional tachycardia: Junctional tachycardia originates from the atrioventricular (AV) node, with a faster rate and usually no visible P waves preceding the QRS complexes.

B. Sinus tachycardia: Sinus tachycardia is characterized by a regular, rapid heart rhythm originating from the sinus node, typically seen after exercise, with identifiable P waves before each QRS complex.

C. Atrial flutter: Atrial flutter presents with a “sawtooth” pattern of P waves, indicating rapid atrial contractions, which is different from sinus tachycardia.

D. Ventricular fibrillation: Ventricular fibrillation is a chaotic and irregular rhythm originating from the ventricles, which is a life-threatening condition.
