What should a CNA do if Mr. Johnson is cold, clammy, and confused?

In a situation where a patient like Mr. Johnson exhibits symptoms of being cold, clammy, and confused, the appropriate action is to page the charge nurse. These symptoms can indicate potential medical emergencies, such as hypoglycemia or shock, which require immediate assessment and intervention by a licensed nurse.

Paging the charge nurse ensures that a qualified professional can evaluate Mr. Johnson's condition, provide any necessary treatments, and decide on the best course of action. This intervention is crucial since the CNA must always work under the guidance of a nurse when faced with potentially serious health changes in a patient.

Taking his temperature, administering glucose tablets, or waiting for the nurse to return may delay critical intervention. Therefore, the most responsible and effective choice is to alert the charge nurse promptly for further assessment and care.
