Why should respirations be counted immediately after taking the pulse?

Counting respirations immediately after taking the pulse is important because individuals may alter their breathing patterns if they are aware of being observed. This can lead to a situation where the respiratory rate is inaccurately assessed. When someone knows their breathing is being monitored, they might breathe more rapidly or deliberately, which does not reflect their true resting respiratory rate. By measuring respirations right after taking the pulse, the individual is likely to be less consciously aware that they are being observed, resulting in a more natural and accurate rate.

The other choices do not hold the same relevance. While it may seem that counting breaths immediately after taking the pulse is efficient, the primary concern is the integrity of the data collected. Simply waiting to count the respirations may not necessarily lead to a significant difference in work for the nursing assistant, nor does the act of waiting impact the physiological mechanics of respiration itself (which is why the option regarding the chest's rise and fall is inaccurate). Ultimately, ensuring accurate respiration measurements is critical for patient assessment, and immediate observation helps achieve this.
