Correct Answer is A

Explanation

A. Document the finding and continue to monitor the client: A PR interval of 0.24 seconds indicates first-degree AV block, which is often asymptomatic and benign if vital signs are stable. No immediate intervention is required other than continued monitoring.

B. Prepare the client for temporary pacemaker insertion: Pacemakers are not indicated for asymptomatic first-degree AV block.

C. Notify the health care provider immediately and then administer epinephrine IV: This is unnecessary as the client is stable and shows no signs of hemodynamic compromise.

D. Administer atropine per agency bradycardia protocol and then notify the health care provider: Atropine is not required for a stable heart rate of 72 bpm.

Correct Answer is B

Explanation

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.
