Emergency Medical Technician (EMT) Basic Certification Practice Exam

What is a common cardiovascular change seen in geriatric patients during a medical emergency?

1. Rise in blood pressure

2. Normal blood pressure during shock

3. Increased heart rate

4. Better oxygenation

The correct answer is: Normal blood pressure during shock

The correct answer highlights that geriatric patients may present with normal blood pressure even in the context of shock. This phenomenon occurs due to several age-related physiological changes. As people age, their cardiovascular system often becomes less responsive to stressors, including those that would typically lead to an increase in heart rate or blood pressure in younger individuals. In medical emergencies, older adults may rely on their body’s compensatory mechanisms differently. For example, decreased vascular elasticity can result in less effective blood pressure regulation. Furthermore, some elderly patients may exhibit signs of shock through other parameters, such as altered mental status or weakness, even when blood pressure readings initially appear normal. Understanding this aspect of geriatric physiology is crucial for EMTs because it emphasizes the need for careful assessment beyond just vital signs. Since geriatric patients often have comorbidities and may be on medications that affect cardiovascular functioning, relying solely on blood pressure as an indicator of their condition may not be effective. This recognition is essential for providing appropriate care and making decisions during emergencies involving older adults.
