What vital sign indicates the need for immediate nursing attention after a dressing change?

A pulse rate of 110 beats per minute is indicative of tachycardia, which can suggest a variety of underlying issues, including pain, anxiety, or potential complications from the dressing change, such as bleeding or infection. In the context of post-operative or post-procedure care, an elevated heart rate is particularly concerning and should prompt immediate assessment and intervention. This is especially critical since a significant change in vital signs can reflect a decline in the patient's physiological status.

In contrast, a temperature of 98.2 °F is within normal limits and does not require immediate nursing attention. A respiratory rate of 20 breaths per minute is also within the normal range for adults, and a blood pressure of 120/80 is considered normal and stable. Thus, among the choices provided, an elevated pulse is the most urgent indicator necessitating nursing assessment and potential intervention.
