A client in chest pain has an assessment finding that requires immediate action. Which finding is this?

• A. Blood pressure 120/80 mmHg
• B. Respiratory rate 18 breaths per minute
• C. Oxygen saturation 98%
• D. Radial pulse of 110 beats per minute and irregular

Answer: (D)

In chest pain, a sign that demands immediate action is a rapid, irregular pulse. An irregular rhythm at about 110 beats per minute points to a possible arrhythmia, such as atrial fibrillation with rapid ventricular response or another conduction disturbance. In the context of chest pain, this can rapidly compromise cardiac output and worsen ischemia, making prompt assessment essential. The appropriate rapid steps are continuous cardiac monitoring and an immediate 12-lead ECG to identify the exact rhythm and guide urgent treatment if needed. The other vital signs—blood pressure around 120/80, respiratory rate about 18, and oxygen saturation near 98%—are within normal limits and do not, on their own, signal an immediate threat requiring urgent intervention.
