A nurse is assessing a toddler who has infective endocarditis. Which of the following findings should the nurse expect?

A. New heart murmur: A new or changing heart murmur is a common clinical manifestation of infective endocarditis due to valve damage. B. Weight gain: Weight loss, not weight gain, is more typical due to decreased appetite and systemic illness. C. Bradycardia: Tachycardia (increased heart rate) is more commonly associated with infection, not bradycardia. D. Decreased body temperature: Fever (elevated body temperature), not hypothermia, is expected in infective endocarditis.
