1. 1. The nurse obtains a health history from an older adult with a prosthetic mitral valve who has symptoms of infective endocarditis (IE).Which question by the nurse helps identify a risk factor for IE? a. "Do you have a history of a heart attack?" b. "Is there a family history of endocarditis?" c. "Have you had any recent immunizations?" d. "Have you had dental work done recently?": Answer D Dental procedures place the patient with a prosthetic mitral valve at risk for IE. Myocardial infarction, immunizations, and a family history of endocarditis are not risk factors for IE. 2. 2. What finding should the nurse expect during the assessment of a young adult with infective endocarditis (IE)? a. Substernal chest pressure b. A new regurgitant murmur c. A pruritic rash on the chest d. Involuntary muscle movement: Answer B New regurgitant murmurs occur in IE because vegetations on the valves prevent valve closure. Substernal chest discomfort, rashes, and involuntary muscle movement are clinical manifestations of other cardiac disorders such as angina and rheumatic fever. 3. 3. Which assessment finding(s) indicate to the nurse that a patient with infective endocarditis has decreased cardiac output? a. Fever, chills, and diaphoresis b. Urine production of 25 mL/hr c. Increase in heart rate of 15 beats/min with walking d. Petechiae on the inside of the mouth and conjunctiva: Answer B Decreased renal perfusion caused by inadequate cardiac output will lead to decreased urine
