Final answer:
The answer is a) True. While decreased blood pressure is a common symptom of shock, not all older patients with shock will experience low blood pressure. Other signs and symptoms should be monitored.
Step-by-step explanation:
The answer to the question, "Do not equate blood pressure with shock in older patients," is a) True. It is important to understand that while decreased blood pressure is a common symptom of shock, not all older patients with shock will experience low blood pressure. Shock is a life-threatening condition where the circulatory system fails to supply enough oxygen and nutrients to the tissues. Therefore, it is crucial to monitor other signs and symptoms of shock, in addition to blood pressure, in older patients.
For example, systemic blood pressure needs to stay above 60 to ensure proper filtration, and a patient with a blood pressure reading of 70/45 arriving at the emergency department confused and complaining of thirst could be exhibiting signs of hypovolemic shock. This condition often presents with symptoms such as rapid heart rate, weak pulse, cool and clammy skin, rapid shallow breathing, and thirst due to significant fluid loss or bleeding.
