Answer: D - It is never a good idea to leave a client unattended if they are feeling unwell, and it is best to stay to monitor if their condition is improving or worsening. A client may be experiencing dehydration or slight nausea due to a release of toxins in their system, so small amounts of water or juice may help them. Many times, clients just need a moment to regain their proprioception (knowing where their body is in time and space). If the condition worsens, it is best to keep the client seated or lie them down while you make an effort to reach the client’s emergency contact or doctor.
