An assistive personnel (AP) reports a client's vital signs as tympanic temperature 37.1° C (98.8° F), pulse 42/min, respiratory rate 14/min, and BP 98/77 mm Hg. Which vital sign should the nurse re-measure?

A. The tympanic temperature of 37.1° C (98.8° F) is within normal limits and does not require re-measurement. B. The respiratory rate of 14/min is also within the normal range (12-20 breaths per minute). C. The blood pressure of 98/77 mm Hg is not alarmingly low and does not require immediate re-measurement. D. A pulse rate of 42/min indicates bradycardia (normal resting heart rate is typically between 60-100 bpm), so it is important to re-measure to confirm this finding and assess the client's cardiovascular status.
