Question

Which of the following is the best indicator of shock in a trauma patient?

1) Depressed level of cognition
2) Heart rate of 80
3) Respirations of 18
4) GCS of 15

Answer 1

A depressed level of cognition is the best indicator of shock in a trauma patient because it suggests that the brain is not receiving enough oxygen, which is crucial in cases of shock.

Step-by-step explanation:

The best indicator of shock in a trauma patient among the listed options is a depressed level of cognition. This is because patients in circulatory shock often demonstrate an increased heart rate but decreased blood pressure. They may also appear confused or lose consciousness due to the inadequacy of blood flow and oxygen delivery to the tissues, leading to impaired cellular metabolism. A depressed level of cognition can indicate that the brain is not receiving enough oxygen, which is a critical concern in shock. It is worth noting that although a heart rate of 80 and respirations of 18 can be within normal ranges, they are not direct indicators of shock. A GCS (Glasgow Coma Scale) of 15 is a perfect score and typically would not indicate shock. Therefore, an altered mental status, as suggested by cognitive depression, is a key sign that may point to shock.
