You are caring for two clients with head injuries. Client A lost consciousness at the time of his head injury. He was alert and oriented on arrival in the ED, but 2 hours later he does not respond even when you press on his nail beds. Client B has been hospitalized for 1 day. He has not been fully alert since admission and continues to be lethargic. He requires more and more stimulation to give a response. Which client’s condition is more serious? Explain your choice.
