Question 3

What is the maximum GCS score, and what does a score of 8 or below indicate?

Accepted Answer

Maximum 15; 8 or below = severe brain injury and potential airway compromise

Answer

GCS maximum is 15 (E4+V5+M6). Score <=8 indicates severe brain injury with risk of airway compromise requiring intubation.

Question 4

A patient's capillary refill time is 5 seconds. What does this suggest?

Accepted Answer

Impaired peripheral perfusion — may indicate shock or cardiovascular compromise

Answer

Normal CRT is <2 seconds. A CRT of 5 seconds is significantly prolonged, suggesting impaired perfusion.
