What vital signs may indicate the need for immediate nursing intervention?

Vital signs are critical indicators of a patient's physiological status, and significant changes signal potential life-threatening issues that require immediate attention. Hypotension refers to abnormally low blood pressure, which may reduce blood flow to vital organs and result in shock or organ failure. Tachycardia, or an elevated heart rate, can indicate various conditions, including dehydration, hemorrhage, infection, or cardiac issues. Together, these significant changes suggest that the patient's condition is deteriorating, necessitating prompt assessment and intervention by nursing staff to prevent further complications or deterioration in their health status.

In contrast, normal respiratory rates, stable blood glucose levels, and consistent body temperatures do not present immediate concerns in the same way that hypotension and tachycardia do. They may still require monitoring but do not indicate an acute crisis demanding urgent nursing action. Thus, the correct choice highlights the vital signs that signal the need for prompt and possibly life-saving intervention.
