Florida State Paramedic Practice Exam

What does a pH level above 7.45 indicate?

1. Acidosis

2. Normal pH

3. Alkalosis

4. Respiratory failure

The correct answer is: Alkalosis

A pH level above 7.45 indicates alkalosis, a condition characterized by an increased alkalinity of the body's fluids. The normal physiological pH range is typically between 7.35 and 7.45, so a pH greater than 7.45 suggests that the blood is less acidic and more basic than normal. Alkalosis can be caused by various factors, including excessive loss of acid, increased bicarbonate levels, or hyperventilation leading to decreased carbon dioxide levels. Understanding the significance of pH levels is critical for paramedics, as it helps assess a patient's acid-base status, which is pivotal in diagnosing and managing various medical conditions. In specific contexts, such as a patient with respiratory issues, high pH values can indicate a primary respiratory alkalosis due to hyperventilation. This can help guide treatment decisions in emergency situations. Recognizing the implications of altered pH levels is essential for effective patient care in prehospital settings.
