A nurse has just received change-of-shift report for four clients. Which of the following clients should the nurse assess first?

A. Correct – This client is at risk for hypoglycemia, which can cause altered mental status, seizures, and coma. The nurse should reassess blood glucose levels to ensure the intervention was effective. B. Incorrect – The client with an IV infusion running low does need attention but is not at immediate risk. The nurse can replace the IV fluid after checking on the more critical client. C. Incorrect – The client scheduled for a procedure needs preparation, but there is no immediate threat to safety. D. Incorrect – The client who received pain medication 30 minutes ago needs reassessment, but pain management is a lower priority than monitoring a potentially unstable client.
