Final answer:
Two signs of impaired consciousness are difficulty in motor coordination, shown in an inability to perform simple motor tasks, and a reduced level of alertness, such as not responding to the touch of a pen.
Step-by-step explanation:
Two signs of impaired or reduced consciousness can include:
- Difficulty in motor coordination and balance, which may be manifested in the inability to perform simple tasks like raising eyebrows, shrugging shoulders, or resistance against arms and legs movements.
- A reduced level of alertness, where a patient may show a lack of response to external stimuli such as the touch of a pen, as described in the scenario of not feeling the pen on certain limbs.
These symptoms could suggest issues within the sensory system or the central nervous system and prompt further investigation through assessments like a CT scan. In cases of potential stroke, tools like the mnemonic FAST are used to quickly identify signs requiring immediate medical intervention.
