The nurse is caring for clients on a cardiac unit. Which client would the nurse assess first?

A. The client diagnosed with endocarditis who has a temperature of 100°F: A low-grade fever in endocarditis should be monitored, but it is not immediately life-threatening. While infection is a concern, it does not require urgent intervention compared with acute cardiac symptoms. B. The client diagnosed with cardiomyopathy who has bilateral 4+ peripheral edema: Severe edema indicates fluid overload and chronic heart failure, but it is generally a slower-developing complication. Assessment and interventions are important, but it is not as urgent as new-onset chest pain. C. The client diagnosed with aortic valve stenosis who has weakness: Weakness may indicate decreased cardiac output, but unless accompanied by other acute signs like hypotension, chest pain, or syncope, it is lower priority compared with ongoing chest pain. D. The client diagnosed with angina who is reporting chest pain: Acute chest pain can indicate myocardial ischemia or an evolving myocardial infarction, which is life-threatening. Immediate assessment and intervention to relieve pain, monitor vital signs, and prevent cardiac complications take priority over other stable or chronic conditions.
