What should the nurse do first if a patient has a significant change in a lab value?

When a patient shows a significant change in a lab value, the first step a nurse should take is to assess the patient for related symptoms. This approach is crucial because it helps determine the immediate impact of the altered lab result on the patient's health and well-being. By conducting a thorough assessment, the nurse can identify any signs of distress, changes in vital signs, or other physical symptoms that may be linked to the abnormal lab value. This assessment is foundational for providing safe and effective patient care.

Following the assessment, the nurse can then determine whether it is necessary to contact the healthcare provider or take other actions based on the patient's condition. Prioritizing patient assessment allows for a more informed and responsive approach to care, ensuring that any potential complications arising from the lab changes are addressed promptly.
