In patients with respiratory disorders, labs may indicate hypoxia through which finding?

• A. Serum glucose above normal
• B. Elevated platelet count
• C. Decreased arterial oxygen saturation
• D. Normal respiratory rate

Answer: (C)

In patients with respiratory disorders, lab findings that indicate hypoxia typically include decreased arterial oxygen saturation. Hypoxia refers to a deficiency of oxygen in the tissues, and one of the primary ways to assess oxygenation in the blood is through arterial blood gases or pulse oximetry, which measures the saturation of oxygen in the blood. When a patient is experiencing respiratory issues, such as chronic obstructive pulmonary disease (COPD) or asthma exacerbations, the ability to oxygenate blood effectively can be compromised, leading to lower oxygen saturation levels. When arterial oxygen saturation decreases, it directly reflects the body's inability to transport adequate oxygen to tissues, which can signal hypoxia. Therefore, this finding is crucial for diagnosing and managing patients with respiratory disorders. The other choices do not directly relate to hypoxia. Elevated serum glucose may be observed in various metabolic conditions but does not indicate oxygen saturation levels. An elevated platelet count is often associated with inflammatory states or other pathological conditions and does not directly indicate respiratory function or oxygenation. A normal respiratory rate, while potentially observed in some patients, does not provide sufficient information about oxygenation status, as individuals may maintain a normal rate even when experiencing hypoxia due to compensatory mechanisms. Thus, decreased arterial oxygen saturation is the most
