Which of the following best indicates a good outcome in a cardiac examination of a child?

A stable set of vital signs and the absence of distress are critical indicators of a good outcome in a cardiac examination of a child. Vital signs, including heart rate, respiratory rate, blood pressure, and oxygen saturation, reflect the child's physiological status and overall well-being. Stability in these vital signs suggests that the child's heart is functioning adequately and that there are no immediate cardiovascular concerns. Furthermore, the absence of distress indicates that the child is not experiencing any acute issues that could compromise their health, such as heart failure or significant respiratory problems. The ability to maintain stable vital signs while being free from distress is reassuring and typically signifies a favorable prognosis in a cardiac assessment.
