Final answer:
The nurse should take the client's vital signs and assessments, including respirations, blood pressure, temperature, and pupillary responses.

These vital signs and assessments will help identify any possible underlying medical conditions or causes for the client's symptoms. They can provide important information about the client's overall health and guide further interventions or treatments.
