A nurse is collecting data on a client who is a professional athlete. Which of the following findings should the nurse expect?

A. Hypothermia is defined as a core body temperature below 35°C (95°F). In a healthy, well-conditioned athlete, thermoregulation is generally efficient, so hypothermia would be an abnormal finding and could indicate environmental exposure or illness, not normal athletic physiology. B. Regular cardiovascular training in professional athletes typically improves cardiac output and vascular compliance, often resulting in normal or slightly lower blood pressure. Elevated blood pressure (hypertension) is not expected in this population. C. Professional athletes often develop athlete’s heart, a physiologic adaptation characterized by increased stroke volume and cardiac efficiency. This allows the heart to pump an adequate volume of blood at a lower rate, producing a resting heart rate that is lower than average (bradycardia, typically 40–60 bpm). This is a normal and expected finding in well-trained athletes. D. Oxygen saturation (SpO₂) reflects oxygenation of hemoglobin in arterial blood. In healthy athletes at rest, oxygen saturation is usually 95–100%, and a decrease would suggest respiratory or circulatory compromise, which is not a normal finding for this population.
