Emergency Medical Technician (EMT) Intermediate Practice Exam

An acute accelerated drop in hemoglobin level occurs during which type of crisis?

1. Hypoglycemic

2. Hemolytic

3. Anaphylactic

4. Septicaemic

The correct answer is: Hemolytic

A significant and abrupt decrease in hemoglobin levels is characteristic of a hemolytic crisis. Hemolytic crises occur when there is an accelerated destruction of red blood cells, which leads to the release of hemoglobin into the bloodstream. This process can be triggered by various factors such as infections, autoimmune diseases, blood transfusions reactions, or certain medications. When red blood cells are destroyed, the hemoglobin levels drop rapidly, which can result in symptoms of anemia, including pallor, fatigue, increased heart rate, and shortness of breath. It is critical for EMTs to recognize the signs of a hemolytic crisis, as prompt intervention is crucial to manage the complications arising from severe anemia or shock that can result from this condition. Other options like hypoglycemic and anaphylactic crises primarily pertain to metabolic and allergic reactions, respectively, and are not directly associated with sudden drops in hemoglobin levels. Septicaemic conditions involve systemic infection but are more related to sepsis and its effects rather than a direct and acute decrease in hemoglobin due to red blood cell destruction. Thus, hemolytic crises stand out as the condition most directly linked to an acute decline in hemoglobin.
