A nurse is assessing a client who has infective endocarditis. Which of the following findings should be the priority for the nurse to report to the provider?

Rationale: A. Splinter hemorrhages to the nails are tiny, linear, reddish-brown streaks under the fingernails or toenails caused by microemboli or immune complex deposition. They are a classic peripheral manifestation of infective endocarditis (IE) and help support the diagnosis, but they are not immediately life-threatening and do not typically indicate acute decompensation. While important to document, they are a secondary finding. B. Fever is the most common symptom of infective endocarditis, resulting from the systemic infection caused by bacteria colonizing the heart valves. Fever indicates ongoing infection and may help track the effectiveness of treatment, but it is expected in IE and generally does not require urgent reporting unless accompanied by signs of hemodynamic instability or sepsis. C. Clusters of petechiae in the mouth (often on the soft palate or conjunctiva) also result from emboli or immune-mediated vascular damage. Like splinter hemorrhages, they support the diagnosis but are not immediately dangerous and do not indicate acute compromise. D. Dyspnea is correct because it may indicate pulmonary congestion or heart failure, which can develop from valve destruction, regurgitation, or left-sided heart involvement in infective endocarditis. Dyspnea can also signal pulmonary emboli, acute pulmonary edema, or systemic hypoxia, all of which are life-threatening complications requiring immediate intervention. This makes it the priority finding. The nurse should assess oxygen saturation, respiratory rate, lung sounds, and signs of fluid overload, and promptly report these findings to the provider for urgent management.
