Final answer:
The functional signs that could be present when evaluating an unconscious patient are sudden onset, stable vital signs, and normal breathing.
Step-by-step explanation:
The functional signs that could be present when evaluating an unconscious patient include:
- Sudden onset: If the unconsciousness occurs suddenly, it may indicate a traumatic event or an acute medical condition.
- Stable vital signs: If the patient's vital signs, such as heart rate and blood pressure, are within normal range, it suggests that the unconsciousness is not caused by a critical condition.
- Normal breathing: If the patient is breathing normally, it indicates that the respiratory system is functioning adequately.
It is important to note that gradual onset and responsive to stimuli are not typically associated with unconsciousness. Gradual onset of unconsciousness is more commonly seen in conditions such as drug overdose or metabolic disorders, while responsiveness to stimuli suggests a level of consciousness.
