Which action typically indicates the technician should follow up with the nursing staff?

The action that indicates the technician should follow up with the nursing staff is when the patient exhibits a change in vital signs. Vital signs—such as temperature, pulse, respiration rate, and blood pressure—are crucial indicators of a patient's health status. Any significant alteration in these readings can suggest a potential health issue or change in the patient's condition, warranting further assessment and intervention by a nurse or physician.

In contrast, a patient requesting additional fluids may be common and doesn't necessarily require an immediate follow-up with nursing staff, as it could be within normal limits for patient care based on their medical needs. A patient who is sleeping is typically not a concern unless there are other signs of distress; sleeping can indicate that the patient is stable and comfortable. Finally, a stable blood pressure reading suggests that the patient is currently in a good state regarding their cardiovascular health, and therefore, this does not require follow-up unless there are other concerning symptoms present.
