What information should be provided in pre-arrival instructions (PAI) for a patient in shock?

The correct choice emphasizes the importance of maintaining the patient's warmth and monitoring their condition when they are in shock. In a state of shock, the body is unable to maintain adequate blood flow to vital organs, which can lead to serious complications. Keeping the patient warm helps prevent further complications, such as hypothermia, which can exacerbate the shock.

Additionally, monitoring the patient's condition allows responders to observe changes that may require immediate medical intervention or provide critical information to arriving medical personnel. It's essential to ensure that the patient remains as stable as possible while awaiting further help, making this guidance an essential part of pre-arrival instructions.

Meanwhile, encouraging the patient to walk around is contraindicated as it can lead to further deterioration. Directing immediate transport to a medical facility is important, but it's not a specific instruction that can be carried out by the patient while awaiting help. Advising to drink water could also be unsafe depending on the type of shock (e.g., hypovolemic shock from bleeding) and could delay necessary medical treatment, thus making it unsuitable as well.
