A 33-year-old female presents with lower abdominal quadrant pain. She is conscious and alert but in moderate pain. When you assess her radial pulse and cannot locate it, what should you assess next?

A 33-year-old female presents with lower abdominal quadrant pain. She is conscious and alert but in moderate pain. When you assess her radial pulse and cannot locate it, what should you assess next?

• A. Capillary refill time
• B. Blood pressure in the arm with a cuff
• C. Assess the rate, regularity, and quality of her carotid pulse
• D. Check for distal hair pattern

Answer: (C)

When a peripheral pulse can’t be found, you immediately look for a central pulse to gauge perfusion. The carotid pulse is the quickest and most reliable central pulse to assess in an adult because it’s close to the heart and less affected by peripheral factors. By feeling the carotid and noting its rate, regularity, and quality, you gain essential information about cardiac function and perfusion: a strong, regular carotid pulse suggests adequate circulation, while a weak, irregular, or absent pulse indicates possible shock or other life-threatening issues and requires urgent action. Capillary refill time is not dependable in adults for acute assessment, and distal hair pattern isn’t relevant to perfusion. Measuring blood pressure is important, but you need a palpable pulse to obtain a valid reading, so checking the carotid pulse first is the best next step.
