What should a nurse do if a vital sign reading is outside the normal range?

When a vital sign reading is outside the normal range, the appropriate action is to reassess the vital signs and report any significant changes to a healthcare provider. This approach is critical for several reasons. First, vital signs are key indicators of a patient's physiological status, and abnormal readings could signify potential complications or changes in the patient's condition that require immediate attention.

Reassessing allows the nurse to confirm that the abnormal reading is accurate and not a result of an error in measurement or temporary factors affecting the readings. If the reading remains abnormal, it is important to inform the healthcare provider, who can then evaluate the situation, consider further diagnostic steps, or adjust the treatment plan as necessary.

The other options present inadequate responses. Ignoring an abnormal reading could lead to missed opportunities for intervention. Simply documenting the reading without taking further action fails to address the potential health risks. Consulting the patient's family for input might provide context or information but does not substitute the need for professional medical evaluation and intervention concerning abnormal vital signs.
